The construction of a Universal Source Thesaurus is suggested. Its purpose is to serve as a source in the construction of special schemes, and as a concordance between classification schemes. Certain problems which arise in the planning of a thesaurus are briefly discussed. (13 references) (Author/SJ)

Article discusses academic practices of expecting excessive rigor. (IR)

Proposed a taxonomy of latent structure assumptions for probability matrix decomposition (PMD) that includes the original PMD model and a three-way extension of the multiple classification latent class model. Simulation study results show the usefulness of the taxonomy. (SLD)

Reports on the design of a knowledge base for an automatic classification in the library science field by using the facet classification principles of colon classification. Discusses inputting titles or key words into the computer to create class numbers through automatic subject recognition and processing title key words. (Author/LRW)

Studied complex problem solving in the hospitality industry through interviews with six office staff members and managers. Findings show it is possible to construct a taxonomy of problem types and that the most common approach can be termed "trial and error." (SLD)

Identified categories of counselor self-talk and explored possible dimensions underlying categories. Counselors (N=38) conducted interviews with female client and then completed stimulated-recall, thought-listing exercise. Trained judges categorized resulting 768 self-talk statements into 14 categories with 4 largest being client-focused…

The recent hybrid model of categorization, Attention Learning Covering Map (ALCOVE), combines desirable properties of exemplar models with a connectionist architecture and learning rule. An important property is the apparent ability of ALCOVE to account for base-rate neglect. ALCOVE's base-rate neglect predictions are reexamined, and their…

Examined three- to five-year-old children's attention to thematic relations, such as between a spider and its web, to similarity of shape between objects, and to taxonomic relations while the children identified objects with novel labels. Findings indicated that shape has some primacy in children's searches for referents of novel labels. (LB)

Notes that, in recent work, Moriarty proposed use of differential diagnoses with adolescent satanic cult dabblers and suggested new diagnostic nosologies. Examines Moriarty's work, scrutinizing its justifications, methodology, and technical aspects. Provides suggestions for clarification of diagnostic typologies and directions for empirical…

A new grouping principle, which depends on perceived depth relations and follows a hierarchical embedding scheme, states that elements located within a common region of space will be perceived as grouped together. Common region produces clear powerful grouping effects, yet cannot be reduced to any other known grouping factor. (RLC)

Functional magnetic resonance imaging (fMRI) was used to investigate the representation of sound categories in human auditory cortex. Experiment 1 investigated the representation of prototypical (good) and nonprototypical (bad) examples of a vowel sound. Listening to prototypical examples of a vowel resulted in less auditory cortical activation…

The distribution of striate cortex cells exhibits a maximum number of cells tuned to vertical and horizontal orientations (Mansfield, 1974). This was interpreted as an adaptation of the visual system to the presence in the visual environment of greater amounts of vertical and horizontal information compared to information from other orientations…

The class-inclusion model claims that metaphors (e.g., That exam is a filter) are comprehended by inclusion of the topic (or subject) as a member of an attributive category named after and exemplified by the vehicle (or predicate). In three experiments, participants rated the extent to which a topic concept (e.g., exam) was a member of a vehicle…
