According to the so-called Classical Theory, concepts are mentally represented by individually necessary and jointly sufficient application conditions. One of the principal empirical objections against this view stems from evidence that people judge some instances of a concept to be more typical than others. In this paper we present and discuss four empirical studies that investigate the extent to which this ‘typicality effect’ holds for the concept of basic needs. Through multiple operationalizations of typicality, our studies yielded evidence for a (...) strong effect of this kind: Participants tended to recall the same core examples of the concept in a free-listing task. They judged some basic needs to be more typical than others. The items that were judged to be more typical were listed more frequently in the free-listing task. These items were listed earlier on in the free-listing task. Typical basic needs, as well as non needs, were classified faster than atypical basic needs in a reaction time study. These findings suggest that the concept of basic needs may have a non-classical structure. If so, the quest for a simple and robust intensional analysis of the concept may be futile. (shrink)

This article aims to clarify the notion of a psychiatric disability. The article uses conceptual analysis, examining and applying established definitions of (general) disability to psychiatric disabilities. This analysis reveals that disability as inability to perform according to expectations or norms is related to impairment as deviation from the (statistical) norm, while disability as inability to achieve (personal) goals is related to impairment as deviation from the (personal) ideal. These two views of impairment and disability are distinct from the self-organization (...) view of impairment as disrupted self-creation or disrupted self-repair and of disability as disrupted whole person self-compensation (in relation to an impairment). All these three views of disability pertain to psychiatric disability. Although there is nothing necessarily psychiatric about psychiatric disability other than the psychiatric impairment related to it, the life course and life circumstances typical of many people with (severe) psychiatric disorders may lead to disability and may thus confer some (psychiatric) specificity on this disability. This analysis may facilitate research on specific psychiatric disabilities and a broader scope for psychiatric rehabilitation. (shrink)

Abstract: By focusing on contributions to the literature on function ascription, this article seeks to illustrate two problems with philosophical accounts that are presented as having descriptive aims. There is a motivational problem in that there is frequently no good reason why descriptive aims should be important, and there is a methodological problem in that the methods employed frequently fail to match the task description. This suggests that the task description as such may be the result of “default descriptivism,” a (...) tendency to take considerations that make sense of a practice to be the very considerations that generate it. Although such hypotheses are frequently quite plausible, the fact of the matter may not be very important for the pursuits of philosophers. (shrink)
