Category Formation

with respect to human color categories, steels & belpaeme's (s&b's) simulations over-emphasize the possible influence of language. in humans, color processing is the result of a long evolutionary process in which categories developed without language. common principles of color processing lead to similar color categories, but interindividual variation in color categories exists. even color-deficiencies, causing large differences in color categories, remain inconspicuous in everyday life, thereby contradicting the hypothesis that language could play a role in color category formation.

Conceptual Language

This article examines the emergence of a medical condition increasingly cited as a cause of death in fatality inquiries in Canada: Excited Delirium. Beyond the association between excited delirium and police use of electrical weapons known as Tasers, one common concern about the medical condition is whether or not it is “real.” Bypassing strictly realist or purely constructivist accounts, this article uses the conceptual language of historical ontology and science and technology studies to investigate how excited delirium is enacted within and between disparate medico-legal sites. Contributing to sociologies of death and dying and category formation, it attends to the textually-mediated practices of legal and medical experts in the United States and Canada that labour to produce excited delirium as a coherent medical condition rather than a “diagnosis of exclusion” reached upon autopsy.

Preverbal Children

This paper investigates whether preverbal children form categories at different levels of abstraction in any specific sequence. In a longitudinal study, 20 infants were each tested twice, at 8 and 12 months of age. Half of the children solved a global-level task (animals-furniture), followed by a basic-level task (either dogs-birds, or chairs-tables) during each session. The other half received the basic-level task only. During familiarisation, all infants freely explored a series of four different exemplars from the same category presented one at a time. Infants saw all objects twice, for a total of eight trials. During the test phase, a new exemplar from the familiar category was presented, followed by a different-category exemplar. At 8 months of age, children discriminated between categories in the global-level task, but failed to do so in the basic-level task. At 12 months of age, infants recognised a category change in the basic-level task, but treated both test items as equally new in the global-level task. These findings support the hypothesis that infants younger than 1 year of age show a global-to-basic-level shift in category formation.
