Reports an experiment with tasks involving memory search for a given probe word with respect to a set of semantic category labels for subjects in a word comparison task and a set of semantic category labels for subjects in the categorization task. The memory search process is fundamentally different in categorization and comparison tasks. (CLK)

Three experiments were conducted to examine normal preschool and retarded children's use of similarity relations (two items go together because overall they are the most similar in a given set of stimuli) or dimensional relations (two items go together because they are the same size) as a predominant basis for classification.

This review of Bloom's taxonomy complements and supplements an earlier review which concentrated on its statistical properties. It reviews unpublished studies and published literature over a 25-year period. The focus is on the claimed properties of neutrality, comprehensiveness, cumulative hierarchical structure, and usefulness. (Author/DWH)

Cluster analysis, applied to Carroll's cognitive theory, indicates that the obtained clusters make intuitive sense and imply that taxonomy is possible. Moreover, some clusters are similar to those suggested by other theories, especially the theory of fluid and crystallized intelligence. (Author/CP)

Examines psychological studies on memory and learning for what they reveal about human categorizing processes and the organizing principles and limitations of human memory. Findings suggest considerations for the design of information systems that would take conceptual organization of knowledge into account. (FM)

Investigated multiple coding for children of different ages and tested the generality of strategy effects obtained in single code studies for multiple coding. (Author/DB)

Three studies examined early development of recall. Children between 2 years 9 months and 5 years of age were tested on nine-item lists containing three objects from each of three conceptual categories or nine objects for nine different conceptual categories. (Author/SS)

Claims that people determine whether something is a member of a given artifact kind by inferring that it was successfully created with the intention that it belong to that kind. Discusses function-based and intentional-historical accounts of artifact concepts. Concludes that a rich set of inferential capacities is needed to constitute a theory of…

This review of the literature on the neuropsychology of autism identifies several consistent findings, such as: existence of neuropsychological impairments in a wide range of domains; large individual differences in certain neuropsychological domains; greater difficulty with tasks involving social information; possible association of the amygdala…

The role of equivalence class formation in delayed position recognition span performance was examined with three mentally retarded adults. Matching-to-sample training established equivalence classes. In subsequent span tests, subject-produced numeral names led to dramatic increases in span scores. The equivalences provided precursors of verbal…

Fifty-two undergraduates completed a questionnaire identifying 40 acquaintances, from which 4 were picked systematically from the list. Role descriptions for the four acquaintances, ratings of their relationships, and characteristics of the relationships were assessed. Found evidence for the existence of truly discrete cognitive forms of social…

The matching-to-sample performances of three young adults with autism and four children (ages four to nine) without intellectual disabilities were examined in three experiments using complex sample stimuli. Results for all subjects showed that each of two redundant relevant sample elements and their respective comparison stimuli were substitutable…

It is proposed that there is a modular but interconnected system underlying the perceived hierarchical organization of objects. The discussion centers on neural and cognitive mechanisms of organizing objects within objects in at least four separate subsystems. (SLD)

Humans are fast and accurate at performing an animal categorization task with natural photographs briefly flashed centrally. Here, this central categorization task is compared to a three position task in which photographs could appear randomly either centrally, or at 3.6 [degrees] eccentricity (right or left) of the fixation point. A mild…

Bowdle and Gentner (2005) proposed a reconciliation of the comparison and categorization models of metaphor comprehension. Their career of metaphor model posits that, as a metaphorical term becomes more conventional, its mode of processing shifts from comparison to categorization. However, other recent studies (Chiappe, Kennedy, & Chiappe, 2003;…
