Animal models have long been used to investigate human mental disorders, including depression, anxiety, and schizophrenia. This practice is usually justified in terms of the benefits (to humans) outweighing the costs (to the animals). I argue on utility maximization grounds that we should phase out animal models in neuropsychiatric research. Our leading theories of how human minds and behavior evolved invoke sociocultural factors whose relation to nonhuman minds, societies, and behavior has not been homologized. Thus it is not at all (...) clear that we are gaining the epistemic or clinical benefits we want from this animal-based research. (shrink)

A Kuhnian reformulation of the recent debate in psychiatric nosography suggested that the current psychiatric classification system (the DSM) is in crisis and that a sort of paradigm shift is awaited (Aragona, 2009). Among possible revolutionary alternatives, the proposed fi ve-axes etiopathogenetic taxonomy (Charney et al., 2002) emphasizes the primacy of the genotype over the phenomenological level as the relevant basis for psychiatric nosography. Such a position is along the lines of the micro-reductionist perspective of E. Kandel (1998, 1999), which (...) sees mental disorders reducible to explanations at a fundamental epistemic level of genes and neurotransmitters. This form of micro-reductionism has been criticized as a form of genetic-molecular fundamentalism (e.g. Murphy, 2006) and a multi-level approach, in the form of the burgeoning Cognitive Neuropsychiatry, was proposed. This article focuses on multi-level mechanistic explanations, coming from Cognitive Science, as a possible alternative etiopathogenetic basis for psychiatric classification. The idea of a mechanistic approach to psychiatric taxonomy is here defended on the basis of a better conception of levels and causality. Nevertheless some critical remarks of Mechanism as a psychiatric general view are also offered. (shrink)

Neuroscientists have in recent years turned to building models that aim to generate predictions rather than explanations. This “predictive turn” has swept across domains including law, marketing, and neuropsychiatry. Yet the norms of prediction remain undertheorized relative to those of explanation. I examine two styles of predictive modeling and show how they exemplify the normative dynamics at work in prediction. I propose an account of how predictive models, conceived of as technological devices for aiding decision-making, can come to be (...) adequate for purposes that are defined by both their guiding research questions and their larger social context of application.

The essay questions the role of neurons in the concept of mind. The mind is considered as an emerging but physical property of the brain: a mental brain configuration does exist. This configuration is relatively resistant to brain damage, coma, hypoxia and normal (electro)physiological brain states and is envisioned as a relatively stable (nearly anatomical) structure. Consistent with this idea is that, despite the lifetime turnover of their constituents (e.g. proteins and nucleotides) and morphological changes, brain neurons do not divide. (...) Brain neurons are continuously modified, for example by lifetime experiences: genetic and epigenetic support for this thesis is provided. The presumed mental brain configuration guarantees lifetime storage of information, but does not imply that this information and memories remain unmodified during aging. In principle, neurons permanently affected by mental processes can be identified in vitro or in vivo, despite anticipated practical problems. This essay may help to scientifically legitimate complementary neurobiological ad psychotherapeutic approaches in psychiatry. (shrink)

The Divine Comedy of Dante Alighieri, and its initial part of Inferno, includes several medical terms and descriptions, whose accuracy sometimes overcomes that of a layman. The genial poet has used locutions illustrating pain and sorrow more than forty times in Inferno alone, with words like dolor, dolente and doloroso, that have caused perplexity among translators. The panoply of translations – here we are dealing only with the English versions – will prove that not only the contextual meaning but also (...) the historical setting might create interpretative difficulties. Without obviously giving medical value for granted to all verses that include words like dolor and its derivates, however Dante’s work has been as well under the focus of medical scholars, with many publications of interest. Through comparing the original text mainly with the Oxford’s English version, we have tried to bring into the reader’s attention the painful sensations that Dante abundantly inflicted upon his characters, as an indirect way to test the poet’s perception of this strange and infernal sensation.

Delusional beliefs have sometimes been considered as rational inferences from abnormal experiences. We explore this idea in more detail, making the following points. Firstly, the abnormalities of cognition which initially prompt the entertaining of a delusional belief are not always conscious and since we prefer to restrict the term “experience” to consciousness we refer to “abnormal data” rather than “abnormal experience”. Secondly, we argue that in relation to many delusions (we consider eight) one can clearly identify what the abnormal cognitive (...) data are which prompted the delusion and what the neuropsychological impairment is which is responsible for the occurrence of these data; but one can equally clearly point to cases where this impairments is present but delusion is not. So the impairment is not sufficient for delusion to occur. A second cognitive impairment, one which impairs the ability to evaluate beliefs, must also be present. Thirdly (and this is the main thrust of our chapter) we consider in detail what the nature of the inference is that leads from the abnormal data to the belief. This is not deductive inference and it is not inference by enumerative induction; it is abductive inference. We offer a Bayesian account of abductive inference and apply it to the explanation of delusional belief. (shrink)

In this chapter, we explain how Karl Jaspers’ concept of empathy can be expanded by drawing upon the tradition of philosophical phenomenology. In the first section, we offer an account of Jaspers' concepts of empathy and incomprehensibility as he develops them in General Psychopathology and “The Phenomenological Approach in Psychopathology.” In the second section, we survey the recent literature on overcoming Jaspers' notion of incomprehensibility and expanding his concept of empathy. In the third section, we outline the levels of investigation (...) at which phenomenological inquiries into psychopathology may proceed. These levels of human existence are, in descending order of depth, (1) phenomenal experiences, (2) interpretive frameworks, (3) modes of existence, and (4) existentials. In the fourth and final section, we argue that to fully empathically comprehend patients with schizophrenia and other mental disorders, the possibility of alterations at all four levels of existence must be acknowledged.

The patient with Capgras’ syndrome claims that people very familiar to him have been replaced by impostors. I argue that this disorder is due to the destruction of a representation that the patient has of the mind of the familiar person. This creates the appearance of a familiar body and face, but without the familiar personality, beliefs, and thoughts. The posterior site of damage in Capgras’ is often reported to be the temporoparietal junction, an area that has a role in (...) the mindreading system, a connected system of cortical areas that allow us to attribute mental states to others. Just as the Capgras’ patient claims that that man is not his father, the patient with asomatognosia claims that his arm is not really his. A similar account applies here, in that a nearby brain area, the supramarginal gyrus, is damaged. This area works in concert with the temporoparietal junction and other areas to produce a large representation of a mind inside a body situated in an environment. Damage to the mind-representing part of this system (coupled with damage to executive processes in the prefrontal lobes) causes Capgras’ syndrome, whereas damage to the body-representing part of this system (also coupled with executive damage) causes asomatognosia.

Corlett (2019) raises two groups of challenges against the two-factor theory of delusions: One focuses on weighing “the evidence for … the two-factor theory”; the other aims to question “the logic of the two-factor theory” (p. 166). McKay (2019) has robustly defended the two-factor theory against the first group. But the second group, which Corlett believes is in many aspects independent of the first group and Darby (2019, p. 180) takes as “[t]he most important challenge to the two-factor theory raised (...) by Dr. Corlett”, has by large remained. Here I offer my two cents in response to the second group. More specifically, I argue that Corlett’s challenges to the logic of the two-factor theory, concerning modularity, double dissociation and cognitive penetration, seem to be based on some misunderstandings of the two-factor theory.

Here I review Robert Trivers' 2011 book _The Folly of Fools_, in which he advocates the evolutionary theory of deceit and self-deception that he pioneered in his famous preface to Richard Dawkins' _Selfish Gene_. Although the book contains a wealth of interesting discussion on topics ranging from warfare to immunology, I find it lacking on two major fronts. First, it fails to give a proper argument for its central thesis--namely, that self-deception evolved to facilitate deception of others. Second, the book (...) lacks conceptual clarity with respect to the focal term "self-deception.". (shrink)

The book I review, _Sleights of Mind_, aims to illuminate properties of perceptual systems by discussing human susceptibility to magical illusions. I describe how the authors use psychological principles to explain two tricks, spoon bending and the Miser's Dream. I also argue that the book is congenial to the following view of illusions: susceptibility to illusion is the result of evolutionary trade-offs; perceptual systems must make assumptions in order to function at all, but susceptibility to illusion is the byproduct of (...) such assumptions.
