Argumentum ad lapidem (Latin: “appeal to the stone”) is a logical fallacy that consists in dismissing a statement as absurd without giving proof of its absurdity.
Ad lapidem statements are fallacious because they fail to address the merits of the claim in dispute. The same applies to proof by assertion, where an unproved or disproved claim is asserted as true on no ground other than that of its truth having been asserted.
The name of this fallacy is derived from a famous incident in which Samuel Johnson claimed to disprove Bishop Berkeley‘s immaterialist philosophy (that there are no material objects, only minds and ideas in those minds) by kicking a large stone and asserting, “I refute him thus.”[3] This action, which is said to fail to prove the existence of the stone outside the ideas formed by perception, is said to fail to contradict Berkeley’s argument, and has been seen as merely dismissing it.
Example
Speaker A: Infectious diseases are caused by microbes.
Speaker B: What a ridiculous idea!
Speaker A: How so?
Speaker B: It’s obviously ridiculous.
Speaker B gives no evidence or reasoning, and when pressed, claims that Speaker A’s statement is inherently absurd, thus applying the fallacy.
Ignoratio elenchi (also to known as irrelevantconclusion or missing the point) is the informal fallacy of presenting an argument that may or may not be logically valid and sound, but (whose conclusion) fails to address the issue in question (from Ancient Greek ἔλεγχος elenchos, meaning ‘an argument of disproof or refutation’). It falls into the broad class of relevance fallacies.
Irrelevantconclusion should not be confused with formal fallacy, an argument whose conclusiondoes not follow from its premises (cf. belief bias)
Ignoratio elenchi is one of the fallacies identified by Aristotle in his Organon. In a broader sense he asserted that all fallacies are a form of ignoratio elenchi. A related concept is that of the red herring, which is a deliberate attempt to divert a process of enquiry by changing the subject. Ignoratio elenchi is sometimes confused with straw man argument.
Ignoratio Elenchi, according to Aristotle, is a fallacy which arises from “ignorance of the nature of refutation”. In order to refute an assertion, Aristotle says we must prove its contradictory; the proof, consequently, of a proposition which stood in any other relation than that to the original, would be an ignoratio elenchi. Since Aristotle, the scope of the fallacy has been extended to include all cases of proving the wrong point… “I am required to prove a certain conclusion; I prove, not that, but one which is likely to be mistaken for it; in that lies the fallacy… For instance, instead of proving that ‘this person has committed an atrocious fraud’, you prove that ‘this fraud he is accused of is atrocious;’” … The nature of the fallacy, then, consists in substituting for a certain issue another which is more or less closely related to it, and arguing the substituted issue. The fallacy does not take into account whether the arguments do or do not really support the substituted issue, it only calls attention to the fact that they do not constitute a proof of the original one… It is a particularly prevalent and subtle fallacy and it assumes a great variety of forms. But whenever it occurs and whatever form it takes, it is brought about by an assumption that leads the person guilty of it to substitute for a definite subject of inquiry another which is in close relation with it.
— Arthur Ernest Davies, “Fallacies” in ‘A Text-Book of Logic’
Example 1: A and B are debating as to whether criticizing indirectly has any merit in general.
A: There is no point in people ranting on social media about politics; the president is not going to read it anyway.
B: But it is their social media. People can agree on making a petition or convey notice from many others that they will be signing one based on their concerns.
A: Well, I do not keep up with it anyway.
A attempts to support their position with an argument that politics ought not to be criticized on social media because the message is not directly being heard by the head of state; this would make them guilty of ignoratio elenchi, as people such as B may be criticizing politics because they have a strong message for their peers, or because they wish to bring attention to political matters, rather than ever intending that their views would be directly read by the president.
Example 2: A and B are debating about the law.
A: Does the law allow me to do that?
B: The law should allow you to do that because this and that.
B missed the point. The question was not if the law should allow, but if it does or not.
Dr Johnson’s unique “refutation” of Bishop Berkeley’s immaterialism, his claim that matter did not actually exist but only seemed to exist, has been described as ignoratio elenchi: during a conversation with Boswell, Johnson powerfully kicked a nearby stone and proclaimed of Berkeley’s theory, “I refute it thus!” (See also argumentum ad lapidem.)
Etymology
The phrase ignoratio elenchi is from Latin, meaning ‘an ignoring of a refutation’. Here elenchi is the genitive singular of the Latin noun elenchus, which is from Ancient Greek ἔλεγχος (elenchos), meaning ‘an argument of disproof or refutation’. The translation in English of the Latin expression has varied somewhat. Hamblin proposed “misconception of refutation” or “ignorance of refutation” as a literal translation, John Arthur Oesterle preferred “ignoring the issue”, and Irving Copi, Christopher Tindale and others used “irrelevant conclusion”.

Carl Friedrich Freiherr von Weizsäcker (28 June 1912 – 28 April 2007) was a German physicist and philosopher. He was the longest-living member of the team which performed nuclear research in Germany during the Second World War, under Werner Heisenberg‘s leadership. There is ongoing debate as to whether or not he and the other members of the team actively and willingly pursued the development of a nuclear bomb for Germany during this time.
A member of the prominent Weizsäcker family, he was son of the diplomat Ernst von Weizsäcker, elder brother of the former German PresidentRichard von Weizsäcker, father of the physicist and environmental researcher Ernst Ulrich von Weizsäcker and father-in-law of the former General Secretary of the World Council of Churches, Konrad Raiser.
Weizsäcker made important theoretical discoveries regarding energy production in stars from nuclear fusion processes. He also did influential theoretical work on planetary formation in the early Solar System.
In his late career, he focused more on philosophical and ethical issues, and was awarded several international honors for his work in those areas.

José Manuel Rodríguez Delgado (August 8, 1915 – September 15, 2011) was a Spanish professor of physiology at Yale University, famed for his research on mind control through electrical stimulation of the brain.
Delgrado used permanent brain implants to control behaviour. Later he utilised non-inversive methods.

Abstract - Free behaviour and brain stimulation (1964)
Of the methods used to investigate the neurophysiological basis of behavior, perhaps the most direct and dramatic is electrical stimulation of the brain. Direct stimulation of the brain is considered a crude method for the exploration of cerebral functions, and the understanding of the results is limited. The chapter describes methodology for cinemanalysis, telerecording, and telestimulation to study free behavior during brain stimulation. It also demonstrates that spontaneous activities are recorded, identified and quantified, allowing the systematic study of free and evoked behavior on both individual and social levels. The chapter also discusses the types and significance of behavior evoked by brain stimulation in unrestrained subjects and presents a theory of fragmental organization of behavior. Brain stimulation evokes (1) stereotyped tonic or phasic activity without any emotional disturbance, (2) driving activity to reach an objective with a motor performance adapted to the relations between subject and purpose, (3) changes in behavioral tuning that are detected in isolated animals because of the lack of manifestations, but may modify decisively the character of response to normal stimuli, (4) inhibition of spontaneous or evoked behavior, and (5) abnormal effects such as tremor or seizures. www.sciencedirect.com/science/article/pii/S0074774208607734
Rodríguez Delgado’s research interests centered on the use of electrical signals to evoke responses in the brain. His earliest work was with cats, but he later did experiments with monkeys and humans, including psychiatric patients.[3][4]
Much of Rodríguez Delgado’s work was with an invention he called a stimoceiver, a radio which joined a stimulator of brain waves with a receiver which monitored E.E.G. waves and sent them back on separate radio channels. Some of these stimoceivers were as small as half-dollars. This allowed the subject of the experiment full freedom of movement while allowing the experimenter to control the experiment. This was a great improvement from his early equipment which included visual disturbance in those whose wires ran from the brain to bulky equipment that both recorded data and delivered the desired electrical charges to the brain. This early equipment, while not allowing for a free range of movement, was also the cause of infection in many subjects.[5]
The stimoceiver could be used to stimulate emotions and control behavior. According to Rodríguez Delgado, “Radio Stimulation of different points in the amygdala and hippocampus in the four patients produced a variety of effects, including pleasant sensations, elation, deep, thoughtful concentration, odd feelings, super relaxation, colored visions, and other responses.” Rodríguez Delgado stated that “brain transmitters can remain in a person’s head for life. The energy to activate the brain transmitter is transmitted by way of radio frequencies.”[6]
Using the stimoceiver, Rodríguez Delgado found that he could not only elicit emotions, but he could also elicit specific physical reactions. These specific physical reactions, such as the movement of a limb or the clenching of a fist, were achieved when Rodríguez Delgado stimulated the motor cortex. A human whose implants were stimulated to produce a reaction were unable to resist the reaction and so one patient said “I guess, doctor, that your electricity is stronger than my will”. Some consider one of Rodríguez Delgado‘s most promising finds is that of an area called the septum within the limbic region. This area, when stimulated by Rodríguez Delgado, produced feelings of strong euphoria. These euphoric feelings were sometimes strong enough to overcome physical pain and depression.[2]
Rodríguez Delgado created many inventions and was called a “technological wizard” by one of his Yale colleagues. Other than the stimoceiver, Rodríguez Delgado also created a “chemitrode” which was an implantable device that released controlled amounts of a drug into specific brain areas. Rodríguez Delgado also invented an early version of what is now a cardiac pacemaker.[2]
In Rhode Island, Rodríguez Delgado did some work at what is now a closed mental hospital. He chose patients who were “desperately ill patients whose disorders had resisted all previous treatments” and implanted electrodes in about 25 of them. Most of these patients were either schizophrenics or epileptics. To determine the best placement of electrodes within the human patients, Delgado initially looked to the work of Wilder Penfield, who studied epileptics’ brains in the 1930s, as well as earlier animal experiments, and studies of brain-damaged people.[2]
The most famous example of the stimoceiver in action occurred at a Córdoba bull breeding ranch. Rodríguez Delgado stepped into the ring with a bull which had had a stimoceiver implanted within its brain. The bull charged Delgado, who pressed a remote control button which caused the bull to stop its charge. Always one for theatrics, he taped this stunt and it can be seen today.[7] The region of the brain Rodríguez Delgado stimulated when he pressed the hand-held transmitter was the caudate nucleus. This region was chosen to be stimulated because the caudate nucleus is involved in controlling voluntary movements.[2] Rodríguez Delgado claimed that the stimulus caused the bull to lose its aggressive instinct.
Although the bull incident was widely mentioned in the popular media, Rodríguez Delgado believed that his experiment with a female chimpanzee named Paddy was more significant. Paddy was fitted with a stimoceiver linked to a computer that detected the brain signal called a spindle which was emitted by her part of the brain called the amygdala. When the spindle was recognized, the stimoceiver sent a signal to the central gray area of Paddy’s brain, producing an ‘aversive reaction’. In this case, the aversive reaction was an unpleasant or painful feeling. The result of the aversive reaction to the stimulus was a negative feedback to the brain.[2] Within hours her brain was producing fewer spindles as a result of the negative feedback.[8] As a result, Paddy became “quieter, less attentive and less motivated during behavioral testing”. Although Paddy’s reaction was not exactly ideal, Rodríguez Delgado hypothesized that the method used on Paddy could be used on others to stop panic attacks, seizures, and other disorders controlled by certain signals within the brain.[2] [9][10]
Publication
José Rodríguez Delgado authored 134 scientific publications within two decades (1950-1970) on electrical stimulation on cats, monkeys and patients – psychotic and non-psychotic. In 1963, New York Times featured his experiments on their front page. Rodríguez Delgado had implanted a stimoceiver in the caudate nucleus of a fighting bull. He could stop the animal mid-way that would come running towards a waving red flag.[11]
He was invited to write his book Physical Control of the Mind: Toward a Psychocivilised Society as the forty-first volume in a series entitled World Perspectives edited by Ruth Nanda Anshen. In it Rodríguez Delgado has discussed how we have managed to tame and civilize our surrounding nature, arguing that now it was time to civilize our inner being. The book has been a centre of controversy since its release.[1] The tone of the book was challenging and the philosophical speculations went beyond the data. Its intent was to encourage less cruelty, and a more benevolent, happier, better man, however it clashed religious sentiments.
José Rodríguez Delgado continued to publish his research and philosophical ideas through articles and books for the next quarter century. He in all wrote over 500 articles and six books. His final book in 1989, was named Happiness and had 14 editions.
Delgado later learned he could duplicate the results he got with the stimoceiver without any implants at all, using only specific types of electromagnetic radiation interacting with the brain. He lamented he didn’t have access to the technology when Franco was in power, as it would have allowed him to control the dictator at a distance.

“INTRODUCTION the cerebellum is a neural structure, of a crystalline like organization, present in all vertebrates. its progressive growth from fishes to mammals, and particularly in primates, takes place following the repetition of a primitive cellular plan and connectivity. development the cerebellum is organized in folia located one behind the other in the rostrocaudal axis, and placed transversally on the brain stem. the cerebellar cortex has five types of neuron: purkinje, stellate, basket, golgi and granule cells. apart from granule cells, the other cell types are inhibitory in nature. afferent fibers to the cerebellar cortex are of two types (mossy and climbing) and carry information from somatosensory, vestibular, acoustic and visual origins, as well as from the cerebral cortex and other brain stem and spinal motor centers. the only neural output from the cerebellar cortex is represented by purkinje axons that synapse on the underlying deep nuclei. cerebellar nuclei send their axons towards many brain stem centers and, by thalamic relay nuclei, act on different cortical areas. functionally, the cerebellum seems to be organized in small modules, similar in structure, but different in the origin and end of their afferent and efferent fibers. the cerebellum is involved in the coordination or integration of motor and cognitive processes. conclusion although cerebellar lesion does not produce severe motor paralysis, loss of sensory inputs or definite deficits in cognitive functions, its certainly affects motor performance and specific perceptive and cognitive phenomena.”

“THe method for the permanent placement of multiple lead electrodes in the brain of animals was developed by one of us four years ago. during this time, its use in the conscious cat and monkey has revealed that motor effects and changes in behavior can be elicited by electrical stimulation of various parts of the brain; the placement of the electrode has not been associated with infection and during several months time has caused only slight gliosis formation about the needle electrode. with this experience in animals and in the hope that it might be helpful in establishing a more physiological basis for psychosurgical procedures, we have modified this technique for use in psychotic patients.”

“The use of brain-derived signals for controlling external devices has long attracted the attention from neuroscientists and engineers during last decades. although much effort has been dedicated to establishing effective brain-to-computer communication, computer-to-brain communication feedback for closing the loop” is now becoming a major research theme. while intracortical microstimulation of the sensory cortex has already been successfully used for this purpose, its future application in humans partly relies on the use of non-invasive brain stimulation technologies. in the present study, we explore the potential use of transcranial alternating-current stimulation (tacs) for synthetic tactile perception in alert behaving animals. more specifically, we determined the effects of tacs on sensory local field potentials (lfps) and motor output and tested its capability for inducing tactile perception using classical eyeblink conditioning in the behaving animal. we demonstrated that tacs of the primary somatosensory cortex vibrissa area could indeed substitute natural stimuli during training in the associative learning paradigm.”
“Sociologists have long studied how moral entrepreneurs construct claims-making campaigns. however, their opponents’ strategies to mount counterclaimsmaking campaigns are less studied. this article examines how the world wrestling federation (wwf) used humor to attack its enemy, the parents television council. by using narrative structures familiar to its fans, the wwf exploited characteristics of its opponent suitable for parody. it created a group of wrestlers called the right to censor who preached the moral values espoused by the parents television council, yet were the most flagrant cheaters in the industry. this case study shows that under the right circumstances counterclaimsmaking using irony and satire can be effective.

“The snowden revelations about national security agency surveillance; starting in 2013; along with the ambiguous complicity of internet companies and the international controversies that followed provide a perfect segue into con- temporary conundrums of surveillance and big data. attention has shifted from late c20th information technologies and networks to a c21st focus on data; currently crystallized in ‘“big data.”’ big data intensifies certain surveillance trends associated with information technology and networks; and is thus implicated in fresh but fluid configurations. this is considered in three main ways: one; the capacities of big data (including metadata) intensify surveillance by expanding interconnected datasets and analytical tools. existing dynamics of influence; risk-management; and control increase their speed and scope through new techniques; especially predictive analytics. two; while big data appears to be about size; qualitative change in surveillance practices is also perceptible; accenting consequences. important trends persist – the control motif; faith in technology; public-private synergies; and user-involvement – but the future-orientation increasingly severs surveillance from history and memory and the quest for pattern-discovery is used to justify unprecedented access to data. three; the ethical turn becomes more urgent as a mode of critique. modernity’s predilection for certain definitions of privacy betrays the subjects of surveillance who; so far from conforming to the abstract; disembodied image of both computing and legal practices; are engaged and embodied users-in-relation whose activities both fuel and foreclose surveillance.”

“Current revelations about the secret us-nsa program, prism, have con-firmed the large-scale mass surveillance of the telecommunication and electronic messages of governments, companies, and citizens, including the united states’ closest allies in europe and latin america. the trans-national ramifications of surveillance call for a re-evaluation of contempo-rary world politics’ practices. the debate cannot be limited to the united states versus the rest of the world or to surveillance versus privacy; much more is at stake. this collective article briefly describes the specificities of cyber mass surveillance, including its mix of the practices of intelligence services and those of private companies providing services around the world. it then investigates the impact of these practices on national secu-rity, diplomacy, human rights, democracy, subjectivity, and obedience.”

The nucleus accumbens has a significant role in the cognitive processing of motivation, aversion, reward (i.e., incentive salience, pleasure, and positive reinforcement), and reinforcement learning (e.g., Pavlovian-instrumental transfer).
Sagittal MRI slice with highlighting (red) indicating the nucleus accumbens.
The nucleus accumbens (NAc or NAcc), also known as the accumbens nucleus, or formerly as the nucleus accumbens septi (Latin for nucleus adjacent to the septum) is a region in the basal forebrain rostral to the preoptic area of the hypothalamus.[1] The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum. The ventral striatum and dorsal striatum collectively form the striatum, which is the main component of the basal ganglia.The dopaminergic neurons of the mesolimbic pathway project onto the GABAergic medium spiny neurons of the nucleus accumbens and olfactory tubercle. Each cerebral hemisphere has its own nucleus accumbens, which can be divided into two structures: the nucleus accumbens core and the nucleus accumbens shell. These substructures have different morphology and functions.
Different NAcc subregions (core vs shell) and neuron subpopulations within each region (D1-type vs D2-type medium spiny neurons) are responsible for different cognitive functions. As a whole, the nucleus accumbens has a significant role in the cognitive processing of motivation, aversion, reward (i.e., incentive salience, pleasure, and positive reinforcement), and reinforcement learning (e.g., Pavlovian-instrumental transfer); hence, it has a significant role in addiction. In addition, part of the nucleus accumbens core is centrally involved in the induction of slow-wave sleep. The nucleus accumbens plays a lesser role in processing fear (a form of aversion), impulsivity, and the placebo effect. It is involved in the encoding of new motor programs as well.
Dölen, G., Darvishzadeh, A., Huang, K. W., & Malenka, R. C.. (2013). Social reward requires coordinated activity of nucleus accumbens oxytocin and serotonin. Nature
“Social behaviours in species as diverse as honey bees and humans promote group survival but often come at some cost to the individual. although reinforcement of adaptive social interactions is ostensibly required for the evolutionary persistence of these behaviours, the neural mechanisms by which social reward is encoded by the brain are largely unknown. here we demonstrate that in mice oxytocin acts as a social reinforcement signal within the nucleus accumbens core, where it elicits a presynaptically expressed long-term depression of excitatory synaptic transmission in medium spiny neurons. although the nucleus accumbens receives oxytocin-receptor-containing inputs from several brain regions, genetic deletion of these receptors specifically from dorsal raphe nucleus, which provides serotonergic (5-hydroxytryptamine; 5-ht) innervation to the nucleus accumbens, abolishes the reinforcing properties of social interaction. furthermore, oxytocin-induced synaptic plasticity requires activation of nucleus accumbens 5-ht1b receptors, the blockade of which prevents social reward. these results demonstrate that the rewarding properties of social interaction in mice require the coordinated activity of oxytocin and 5-ht in the nucleus accumbens, a mechanistic insight with implications for understanding the pathogenesis of social dysfunction in neuropsychiatric disorders such as autism.”
Trezza, V., Damsteegt, R., Achterberg, E. J. M., & Vanderschuren, L. J. M. J.. (2011). Nucleus Accumbens -Opioid Receptors Mediate Social Reward. Journal of Neuroscience
“Positive social interactions are essential for emotional well-being and proper behavioral development of young individuals. here, we studied the neural underpinnings of social reward by investigating the involvement of opioid neurotransmission in the nucleus accumbens (nac) in social play behavior, a highly rewarding social interaction in adolescent rats. intra-nac infusion of morphine (0.05-0.1 μg) increased pinning and pouncing, characteristic elements of social play behavior in rats, and blockade of nac opioid receptors with naloxone (0.5 μg) prevented the play-enhancing effects of systemic morphine (1 mg/kg, s.c.) administration. thus, stimulation of opioid receptors in the nac was necessary and sufficient for morphine to increase social play. intra-nac treatment with the selective μ-opioid receptor agonist [d-ala(2),n-mephe(4),gly(5)-ol]enkephalin (damgo) (0.1-10 ng) and the μ-opioid receptor antagonist cys-tyr-d-trp-arg-thr-pen-thr-nh(2) (ctap) (0.3-3 μg) increased and decreased social play, respectively. the δ-opioid receptor agonist dpdpe ([d-pen(2),d-pen(5)]-enkephalin) (0.3-3 μg) had no effects, whereas the κ-opioid receptor agonist u69593 (n-methyl-2-phenyl-n-[(5r,7s,8s)-7-(pyrrolidin-1-yl)-1-oxaspiro[4.5]dec-8-yl]acetamide) (0.01-1 μg) decreased social play. intra-nac treatment with β-endorphin (0.01-1 μg) increased social play, but met-enkephalin (0.1-5 μg) and the enkephalinase inhibitor thiorphan (0.1-1 μg) were ineffective. damgo (0.1-10 ng) increased social play after infusion into both the shell and core subregions of the nac. last, intra-nac infusion of ctap (3 μg) prevented the development of social play-induced conditioned place preference. these findings identify nac μ-opioid receptor stimulation as an important neural mechanism for the attribution of positive value to social interactions in adolescent rats. altered nac μ-opioid receptor function may underlie social impairments in psychiatric disorders such as autism, schizophrenia, or personality disorders.”
Day, J. J., Roitman, M. F., Wightman, R. M., & Carelli, R. M.. (2007). Associative learning mediates dynamic shifts in dopamine signaling in the nucleus accumbens. Nature Neuroscience
“The ability to predict favorable outcomes using environmental cues is an essential part of learned behavior. dopamine neurons in the midbrain encode such stimulus-reward relationships in a manner consistent with contemporary learning models, but it is unclear how encoding this translates into actual dopamine release in target regions. here, we sampled dopamine levels in the rat nucleus accumbens on a rapid (100 ms) timescale using electrochemical technology during a classical conditioning procedure. early in conditioning, transient dopamine-release events signaled a primary reward, but not predictive cues. after repeated cue-reward pairings, dopamine signals shifted in time to predictive cue onset and were no longer observed at reward delivery. in the absence of stimulus-reward conditioning, there was no shift in the dopamine signal. consistent with proposed roles in reward prediction and incentive salience, these results indicate that rapid dopamine release provides a reward signal that is dynamically modified by associative learning.”
Wise, R.. (1989). Brain Dopamine And Reward. Annual Review of Psychology
“While the evidence is strong that dopamine plays some fundamental and special role in the rewarding effects of brain stimulation, psychomotor stimulants, opiates, and food, the exact nature of that role is not clear. one thing is clear: dopamine is not the only reward transmitter, and dopaminergic neurons are not the final common path for all rewards. dopamine antagonists and lesions of the dopamine systems appear to spare the rewarding effects of nucleus accumbens and frontal cortex brain stimulation (simon et al 1979) and certainly spare the rewarding effects of apomorphine (roberts & vickers 1988). it is clear that reward circuitry is multisynaptic, and since dopamine cells do not send axons to each other or receive axons from each other, dopamine can at best serve as but a single link in this circuitry. if dopamine is not a final common path for all rewards, could it be an intermediate common path for most rewards? some workers have argued against such a view, but at present they must do so on incomplete evidence. for example, phillips (1984) has argued that there must be multiple reward systems, functionally independent and organized in parallel with one another. his primary evidence, however, is the fact that brain stimulation is rewarding at different levels of the nervous system. as we have seen in the case of midline mesencephalic stimulation, the location of the electrode tip in relation to the dopamine cells and fibers tells us little about the role of dopamine in brain stimulation reward. it seems clear that the ventral tegmental dopamine system plays a critical role in midline mesencephalic reward, despite the distance from the electrode tip to the dopamine cells where morphine causes its dopamine-dependent facilitory effects or to the dopamine terminals where low-dose neuroleptics presumably cause theirs. until pharmacological challenge has been extended to the cases discussed by phillips, we can only speculate as to the role of dopamine in each of those cases. in the cases where pharmacological challenge has been examined, only nucleus accumbens and frontal cortex have been found to have dopamine-independent reward sites. it is not consistent with the dopamine hypothesis that dopamine-independent reward sites should exist in these areas, since any reward signals carried to nucleus accumbens or frontal cortex by dopamine fibers would-unless we are to believe that reward ‘happens’ at these sites-have to be carried to the next stage of the c…”
www.uni-kiel.de/psychologie/mausfeld/ Mausfeld_Why do the lambs remain silent_2015
Mausfeld focuses on perceptual psychology and also works on the theoretical foundations of experimental psychology and the psychology of understanding. He also deals with the rivalry of cognitive psychology and cognitive neuroscience in cognitive science. Another area of interest is the history of ideas in the natural sciences. He sees a major problem of the relationship between psychology and biology in neurological neo-reductionism. In contrast to biologistic approaches, he sees the peculiarity of the spiritual, inter alia, in the intrinsic multiperspectivity of the mind.
Mausfeld points out that knowledge of neural circuitry and activity is not enough to explain consciousness and thought processes. Not even the behavior of nematodes can be deduced from the activity of their 302 neurons. According to Mausfeld’s view, the relationship between nature and mind must be below the neural level in the sphere of physics. Evidence is given by the fact that nature is actually more enigmatic to us than our consciousness in itself. In modern physics it has become clear that the physical does not have the properties of matter ascribed to it. Mausfeld sees the special aspect of consciousness in the simplicity and wholeness of the subjective experience, which, however, reveals itself to the psychologist as a complex interaction of unconscious factors. The intrinsic multiperspectivity of thinking, which first opens up the possibilities for thought and action alternatives to humans after mouse field, results from the complex interplay of the most varied of factors. White torture and responsibility of science
In his work, Mausfeld illustrates the role of psychologists in the development, application and justification of modern white torture methods. These goals are not, as claimed, the extraction of information, but rather breaking the will, disciplining, humiliating and shaming the victims. In his account, an American Psychological Association (APA) working group to investigate the involvement of psychologists acting on behalf of the Defense Secretary. Mausfeld uses the example of torture research to define ethical and legal principles and limits of scientific work. He regards the observance of human rights as fully binding.
Mausfeld, R.. (2009). Psychology , ’ white torture ’ and the responsibility of scientists. Psychologische Rundschau
According to Mausfeld, the cognitive ones are more important than the affective techniques, since opinions are more stable than emotions. Here Mausfeld examines the following methods:
Representation of facts as opinion
Fragmenting coherent facts so that the context, such as the historical context, is lost
Decontextualization of facts: The context of the facts is removed, so that the facts become incomprehensible isolated individual cases, which have no general relevance
Misleading recontextualization: Information is embedded in a foreign context, so that they take on a different character and, for example, no longer lead to outrage in human rights violations.
Repetition supports the “perceived truth”
Designing the range of opinions so that the desired seems to be in the middle, which most people strive for, if they are unfamiliar, because they then keep to the middle seein it as “neutral and balanced”
Making facts invisible through media selection, distraction and attention control
“Meta-propaganda”: It is part of every propaganda to claim that the news of the enemy is wrong because it is propaganda
The development of more efficient manipulation techniques rests on identifying psychological “weak spots” – those intrinsic design aspects of our mind and principles of human information processing that can be exploited for manipulation purposes. Most importantly, such principles are, by the very nature of our cognitive architecture, beyond conscious control. (…) Our mind has many hard-wired weaknesses that can be exploited for manipulative purposes, that facilitate our utilitarian abuse by the political and economic elites for maintaining and expanding their power. However, we also innately dispose of a rich repertoire of ways to use our reasoning capabilities to recognize manipulative contexts and to actively avoid them. This repertoire is akin to a natural cognitive immune system against being manipulated, but we have to take the deliberate decision to actually use it.
“The cognitive neurosciences are based on the idea that the level of neurons or neural networks constitutes a privileged level of analysis for the explanation of mental phenomena. this paper brings to mind several arguments to the effect that this presumption is ill-conceived and unwarranted in light of what is currently understood about the physical principles underlying mental achievements. it then scrutinizes the question why such conceptions are nevertheless currently prevailing in many areas of psychology. the paper argues that corresponding conceptions are rooted in four different aspects of our common-sense conception of mental phenomena and their explanation, which are illegitimately transferred to scientific enquiry. these four aspects pertain to the notion of explanation, to conceptions about which mental phenomena are singled out for enquiry, to an inductivist epistemology, and, in the wake of behavioristic conceptions, to a bias favoring investigations of input-output relations at the expense of enquiries into internal principles. to the extent that the cognitive neurosciences methodologically adhere to these tacit assumptions, they are prone to turn into a largely a-theoretical and data-driven endeavor while at the same time enhancing the prospects for receiving widespread public appreciation of their empirical findings.”

“The disparity of highlights on specular reflecting surfaces usually differs from the disparity of the surface points. a. kirschmann (1895) proposed that this fact may be used as a binocular cue for gloss perception. this was confirmed by a. blake and h. bülthoff (1990) who found that subjects judged the glossiness of convex ellipsoidal surfaces as most realistic if the disparity of the highlights was close to the physical correct one. extending on this finding, we investigate more closely whether the effect of highlight disparity depends on the sharpness of the highlight and the relative amount of diffuse and specular reflection. we measured the effect of highlight disparity on both perceived strength and perceived authenticity of gloss. we used complex, three-dimensional curved surfaces that were stereoscopically presented on a crt. the reflection characteristics were varied using the phong lighting model. highlights were presented either with or without highlight disparity. in a rating experiment, subjects were asked to judge the strength and the authenticity of the perceived surface glossiness. the presence of highlight disparity lead to an enhancement of both the authenticity and the strength of perceived glossiness. the latter finding was confirmed in an additional matching experiment.”

Mausfeld, R.. (2012). “Colour” As Part of the Format of Different Perceptual Primitives: The Dual Coding of Colour. In Colour Perception: Mind and the Physical World
“The field of colour perception has often been praised in recent years as a paradigm of cognitive science. while this certainly has some validity, it contrasts with the fact that the field makes very little contact with the sort of inquiries into mental representations to be found elsewhere in cognitive science (understood as naturalistic inquiries of the mind/brain). i find this quite puzzling, because in the earlier literature of the field it was clearly recognised-for instance by bühler, gelb, kardos, koffka-that ʹcolourʹ could be understood only as part of the general problem of perceptual representations. their insights could not, of course, take advantage of the theoretical language provided by what has been called the cognitive revolution. for that reason, and also because they were overshadowed by the success of more technical fields, they fell almost entirely into oblivion. the technical fields, successful with respect to their own specific goals, were colorimetry, neurophysiological investigations into peripheral colour coding, and more recently, functionalist-computational approaches that emphasise certain pre-given performance criteria.. the success of these fields has not been hampered by the fact that they share certain common-sense conceptions of colour, particularly the idea that colour is an autonomous attribute that can be studied almost in isolation from other perceptual attributes. because such common-sense conceptions of colour appear to be, by and large, innocuous to advances in these fields, no need has arisen so far to relinquish them. however, precisely because of the successes of these fields inquiries into colour perception, understood as the endeavour to develop explanatory frameworks for the role of ʹcolourʹ within our perceptual and cognitive architecture, have suffered a less fortunate fate. the conceptual vocabulary which inquiries into colour perception 1 borrowed from fields, such as neurophysiology, that pursue different explanatory purposes has remained alien to its intrinsic structure and has veiled its core problems. my interest in colour perception (which, a long time ago, was incited by russellʹs problems of philosophy) has been motivated by the question of how we can, within naturalistic inquiry, describe the conceptual structure with which our perceptual system is biologically endowed. such questions have long been pursued in ethology and have yielded intriguing results. the theoretical picture that is emerging h…”

“The chapter deals with the notion of phenomenal realness, which was first systematically explored by albert michotte. phenomenal realness refers to the impression that a perceptual object is perceived to have an autonomous existence in our mind-independent world. perceptual psychology provides an abundance of phenomena, ranging from amodal completion to picture perception, that indicate that phenomenal realness is an independent perceptual attribute that can be conferred to perceptual objects in different degrees. the chapter outlines a theoretical framework that appears particularly well-suited for dealing with corresponding phenomena. according to this framework, perception can be under- stood as a triggering of conceptual forms by sensor inputs. it is argued that the attribute of phenomenal realness is based on specific types of internal evaluation functions which deal with the segregation of causes conceived as ‘external’ from those conceived as ‘internal’. these evaluation functions integrate different internal sources of ‘knowledge’ about the potential causes for the activation of conceptual forms and provide markers by which conceptual forms can be tagged as ‘external world objects’. ‘reality’,”

Mausfeld, R., & Andres, J.. (2002). Second-order statistics of colour codes modulate transformations that effectuate varying degrees of scene invariance and illumination invariance. Perception
“We argue, from an ethology-inspired perspective, that the internal concepts ‘surface colours’ and ‘illumination colours’ are part of the data format of two different representational primitives. thus, the internal concept of ‘colour’ is not a unitary one but rather refers to two different types of ‘data structure’, each with its own proprietary types of parameters and relations. the relation of these representational structures is modulated by a class of parameterised transformations whose effects are mirrored in the idealised computational achievements of illumination invariance of colour codes, on the one hand, and scene invariance, on the other hand. because the same characteristics of a light array reaching the eye can be physically produced in many different ways, the visual system, then, has to make an ‘inference’ whether a chromatic deviation of the space-averaged colour codes from the neutral point is due to a ‘non-normal’, ie chromatic, illumination or due to an imbalanced spectral reflectance composition. we provide evidence that the visual system uses second-order statistics of chromatic codes of a single view of a scene in order to modulate corresponding transformations. in our experiments we used centre surround configurations with inhomogeneous surrounds given by a random structure of overlapping circles, referred to as seurat configurations. each family of surrounds has a fixed space-average of colour codes, but differs with respect to the covariance matrix of colour codes of pixels that defines the chromatic variance along some chromatic axis and the covariance between luminance and chromatic channels. we found that dominant wavelengths of red-green equilibrium settings of the infield exhibited a stable and strong dependence on the chromatic variance of the surround. high variances resulted in a tendency towards ‘scene invariance’, low variances in a tendency towards ‘illumination invariance’ of the infield.”

“The interpretation of the role of hla-dpb1 in unrelated haematopoietic stem cell transplantation (hsct) is subject to discussion. we have investigated the role of hla-dpb1 allele matching in hsct outcomes in 161 recipients who were hla-a, -b, -c, -drb1 and -dqb1-matched with their unrelated donors at the allelic level (10/10). in addition, we analysed the association of polymorphic amino acid mismatches of dpb1 molecule with hsct end-points, and a previously published permissiveness concept. hla-dpb1 allele mismatches were significantly associated with an increased incidence of acute graft-versus-host disease (agvhd) and worse overall survival (os). the mismatch at amino acid position 69 significantly increased the risk for transplant-related mortality (trm). risk factors for agvhd also included mismatches at positions 8, 9, 35, 76 and 84. this is to our knowledge, the first report of an in vivo effect of single amino acid mismatches on hsct outcomes. in this study, grouping of allelic mismatches into permissive and non-permissive categories and their association with transplantation end-points was relevant for trm but not for other clinical end-points.”

“Sensory systems serve to link the organism to functionally relevant aspects of the physical environment. a mobile organism requires diverse information from the biologi-cal and physical environment and about its internal state for orientation and movement in space and in order to regulate and control its body and behavior. in the course of evolution, with the increased complexity of tasks serv-ing towards orientation and behavioral control there was a growing need to interrelate the diverse sensory chan-nels and also to integrate information about the internal state of the body. this sensory integration required a regulation of awareness to develop which would be able to fi lter the external signals according to internal motiva-tional and emotional states. as sensory systems are cen-tral for behavioral control, the neuronal architecture of sensory systems is intricately interwoven with the motor system. furthermore, evolutionary considerations sug-gest that fundamental features of perception formed the basis for more abstract cognitive achievements and that the underlying general principles are thus also re fl ected in the organization of cognitive processes. for humans, the sensory integratory achievements pertain not only to haptic, visual, auditive, olfactory, and gustatory perception, but also to the perception of the body and its parts [ 6, 27 ] and the relative position of these parts in relation to each other (proprioception) and to their environment, the perception of the viscera (entero-or visceroception), the perception of pain, the perception of physiognomy and body movements and the thus communicated affective expressions and sig-nals, as well as the perception of speech, events, or time. biological species may differently exploit and utilize the physical energies impinging on the organism and organize these energies in the form of sensory modali-ties . by far the largest part of the impinging spatiotempo-ral energy pattern is not processed for biological purposes. only a highly restricted range of this energy pattern is used for the biological function of coupling the organism to its environment (e.g., humans neither can perceive the plain of polarized light nor the direction of the magnetic fi eld). the physical energy is transduced into neural codes in such a way that the particular physical origin of the resulting code is unidenti fi able (e.g., light perception at the eye may originate from optical, mechanical, or electrical stimuli). t…”

“Lustrous surface appearances can be elicited by simple image configurations with no texture or specular highlights, as most prominently illustrated by helmholtz’ demonstration of stereoscopic lustre. three types of explanatory framework have been proposed for stereoscopic lustre, which attribute the phenomenon to a binocular luminance conflict, an internalised physical regularity (helmholtz), or to a disentangling of ‘essential’ and ‘accidental’ attributes in surface representations (hering). in order to investigate these frameworks, we used haploscopically fused half-images of centre-surround configurations in which the luminances of the test patch were dynamically modulated. experiment 1 shows that stereoscopic lustre is not specifically tied to situations of a luminance conflict between the eyes. experiment 2 identifies a novel aspect in the binocular temporal dynamics that provides a physical basis for lustrous appearances, namely the occurrence of a temporal luminance counter-modulation between the eyes. this feature sheds some light on the internal principles underlying a disentangling of ‘accidental’ and ‘essential’ surface attributes. experiment 3 reveals an asymmetry between a light and a dark reference level for the counter-modulations. this finding again suggests an interpretation in terms of an internalised physical regularity with respect to the dynamics of perceiving illuminated surfaces.”
