Studies of the conceptual abilities of nonhuman primates demonstrate the substantial range of these abilities as well as their limitations. Such abilities range from categorization on the basis of shared physical attributes, associative relations and functions to abstract concepts as reflected in analogical reasoning about relations between relations. The pattern of results from these studies point to a fundamental distinction between monkeys and apes in both their implicit and explicit conceptual capacities. Monkeys, but not apes, might be best regarded as (...) “paleo‐logicans” in the sense that they form common class concepts of identity on the basis of identical predicates (i.e., shared features). The discrimination of presumably more abstract relations commonly involves relatively simple procedural strategies mediated by associative processes likely shared by all mammals. There is no evidence that monkeys can perceive, let alone judge, relations‐between‐relations. This analogical conceptual capacity is found only in chimpanzees and humans. Interestingly, the “analogical ape,” like the child, can make its analogical knowledge explicit only if it is first provided with a symbol system by which propositional representations can be encoded and manipulated.

Arguing that we ought to look to psychedelic aesthetics of the 1960s in relation to current crises in liberal democracy, this book emphasizes the intersection of European thought and the psychedelic. The first half of the book focuses on philosophical influences of Herbert Marcuse and Antonin Artaud, while the second half shifts toward literary and theoretical influences of Aldous Huxley on psychedelic aesthetics. Framed within an emergent discourse of political theology, it suggests that taking a postsecular approach to psychedelic aesthetics (...) helps us understand deeper connections between aesthetics and politics.

We argue that formal analogical reasoning is not a uniquely human trait but is found in chimpanzees, if not in monkeys. We also contest the claim that the relational matching-to-sample task is not exemplary of analogical behavior, and we provide evidence that symbolic-like treatment of relational information can be found in nonhuman species, a point in contention with the relational reinterpretation hypothesis.

Using methods from anthropology and cognitive psychology, this study investigated the relationship between clinicians’ folk taxonomies of mental disorder and the Diagnostic and Statistical Manual of Mental Disorders (DSM). Expert and novice psychologists were given sixty-seven DSM-IV diagnoses, asked to discard unfamiliar diagnoses, put the remaining diagnoses into groups that had “similar treatments” using hierarchical (making more inclusive and less inclusive groups) and dimensional (placing groups in a two-dimensional space) methodologies, and give names to the groups in their taxonomies. Clinicians (...) were familiar with a substantially smaller number of diagnoses than are in the DSM. Cultural consensus analysis and follow-up residual agreement analysis revealed similarities across clinicians’ folk taxonomies. Correlations between folk taxonomies and the DSM were moderate. Cluster analysis showed that clinicians preserved DSM higher order categories (e.g., mood disorders) but not the Axis I–Axis II distinction. This study suggests important differences between the way clinicians conceptualize mental disorders and the organization of the DSM-IV. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Should Clinicians’ Views of Mental Illness Influence the DSM?Elizabeth H. Flanagan (bio) and Roger K. Blashfield (bio)Keywordsclinicians, DSM, values, psychopathology, scienceThe relationship between clinicians and the DSM is complex. Clinicians are the primary intended audience of the DSM. However, as Widiger (2007) pointed out in his commentary, there is a tension associated with trying to meet the clinical goals of the DSM and also trying to optimize the (...) scientific goals of the DSM. Most commentators would agree that the recent editions of the DSM (from the DSM-III onward) have favored scientific values (e.g., Sadler 2005). Some commentators have taken sides and aligned themselves with either clinicians or with the science of classification. For instance, Garb (2005) has argued that clinicians should receive incentives to align themselves more closely with the science of the DSM. In contrast, Westen and Shedler (1999) have favored a clinician-based approach to the DSM and have argued that an ideal classification should be based on the prototypes that clinicians use to conceptualize diagnostic categories. Perhaps an extreme suggestion on how to deal with this tension between the values of clinicians and the values of scientists is to adopt the ICD-10 solution and create two versions of the next DSM. One version would be written for clinicians and another for researchers (Phillips et al. 2003).Widiger (2007) wondered whether the two of us as authors are on the fence about how the views of clinicians should affect the DSM. As clinical psychologists who are both clinicians and researchers, we understand his comment, especially in light of our attempt in our article not to overgeneralize from the time-consuming, labor-intensive, yet methodologically limited study we reported in our major paper.Nonetheless, our answer to the question asked in the title of this response, “Should clinicians’ views of mental illness influence the diagnostic manual?” is a clear and unequivocal yes. In our view, too much of the research literature stimulated by the recent DSMs has primarily used the diagnostic criteria in these DSMs to specify patient samples and then perform various experiments to study the DSM categories. We favor a different approach to research which is consistent with a comment once made by the philosopher of science, Karl Popper: “scientific theories originate from myths, and... a myth may contain important anticipations of scientific theories” (1963, 39). We believe that clinicians, with their years [End Page 285] of experience dealing with the ambiguities, the emotionality, and the chaos of psychopathology, have formed complex conceptual systems to try to understand the mysteries of abnormal behavior. We strongly support increased research attempts that will use clinicians as subjects and that will attempt to understand how clinicians use diagnostic concepts to understand patients.Although research on clinicians has not attracted a large amount of attention in the field, there is a long history of such research studies. For instance, in the 1970s, Overall used multivariate techniques to create graphical maps of how clinicians represented relationships among diagnoses (Overall et al. 1977). Widiger has used a similar strategy in some of his research (Widiger et al. 1987). In the early 1980s, a view of concept formation from cognitive psychology was used by Cantor et al. (1980) to look at psychiatric diagnoses as representing prototypes. Horowitz and colleagues extended this research. Blashfield and his colleagues had a grant to use the prototype model to study personality disorders and performed research investigating both case histories (Blashfield et al. 1985) and analyses of diagnostic criteria (Blashfield and Breen 1989; Davis, Blashfield, and McElroy 1993). Westen and colleagues have attempted to reconceptualize DSM personality disorder categories using the prototype model (Westen and Shedler 1999). Ahn and her colleagues (Ahn et al. 2006; Kim and Ahn 2002) have taken more recent applications of ideas from cognitive psychology to study how clinicians use and understand diagnostic categories. Finally, Flanagan and colleagues (Flanagan and Blashfield 2006; Flanagan, Keeley, and Blashfield, in press; Flanagan, Miller, and Davidson, submitted) have used qualitative and quantitative data analysis techniques to try to understand the diagnostic concepts held by experienced clinicians.Besides empirical studies of how clinicians use diagnostic concepts, we also support the increased interest in...

We explore the formal foundations of recent studies comparing aural pattern recognition capabilities of populations of human and non-human animals. To date, these experiments have focused on the boundary between the Regular and Context-Free stringsets. We argue that experiments directed at distinguishing capabilities with respect to the Subregular Hierarchy, which subdivides the class of Regular stringsets, are likely to provide better evidence about the distinctions between the cognitive mechanisms of humans and those of other species. Moreover, the classes of the (...) Subregular Hierarchy have the advantage of fully abstract descriptive (model-theoretic) characterizations in addition to characterizations in more familiar grammar- and automata-theoretic terms. Because the descriptive characterizations make no assumptions about implementation, they provide a sound basis for drawing conclusions about potential cognitive mechanisms from the experimental results. We review the Subregular Hierarchy and provide a concrete set of principles for the design and interpretation of these experiments. (shrink)
