Scientific results are communicated visually in the literature through diagrams, visualizations, and photographs. In this thesis, we developed a figure processing pipeline to classify more than 8 million figures from PubMed Central into different figure types and study the resulting patterns of visual information as they relate to scholarly…

This appendix accompanies the report "Taking the Lead in Science Education: Forging Next-Generation Science Standards. International Science Benchmarking Report," a study conducted by Achieve to compare the science standards of 10 countries. This appendix includes the following: (1) PISA and TIMSS Assessment Rankings; (2) Courses and…

Investigates techniques for automatic classification of book material focusing on: computer-based surrogation of monographic material, book surrogate clustering on basis of content association, evaluation of resultant classifications. Test collection (250 books) is described with surrogation by means of back-of-the-book index, table of contents,…

In two experiments on whether similarity grouping is based on the retinal or the perceived slopes of lines, observers judged the grouping of diagonal lines when a display of vertical and diagonal lines was presented upright and when it was slanted 75 degrees toward the floor. (Editor/RK)

The purpose of this study was to gather normative data bearing on the hierarchical organization of semantic memory. (Author)

In an attempt to regain the perspective of psychological research as a whole, a dimensional model was synthesized from several popular conceptualizations. (Author/RK)

Attempts to determine the extent that typicality effects obtained in previous research on natural semantic categories could be obtained in artificial categories purely as a function of structural principles when the frequency and nature of experience with items were controlled. (Author/RK)

The present study was designed to examine several features of naive subjects' inference processes in a rule-learning task. Attention was primarily directed toward initial classification biases and the amount of transfer of learning occurring among stimuli within the same truth-table class. (Author/RK)

Properties of categories were investigated by analyzing 22 measures of the 56 categories used in the 1969 Battig and Montague norms. A factor analysis of the data indicated that categories in semantic memory possess at least four factors (category familiarity, category size, category-label printed frequency, semantic complexity) that may affect…

The concept of the single group experimental research design is to test the null hypothesis that there is no significant difference between the achievement of the pupils under the experimental treatment and their achievement at their previous rate of progress. (Author)

Attempts to determine whether PI (proactive inhibition) release for taxonomic word categories could be observed for chronic schizophrenics. (Author/RK)

On three occasions over a one-year period 23 children aged 3-4 were asked to match target objects with other objects which were similar to the target in shape or in color but not in both. A sequence of matches to each target was asked for. The structure of these sequences is examined for evidence of classificatory abilities. (Editor)

Subjects learned 24 words from two categories to either a lenient or a stringent criterion and were then tested in an identification task. (Editor)

Two codes that provide access to the identity of an item in memory are the initial letter of its name and the name of a category to which it belongs. This research compares the characteristics of these two modes of access to the identity of a memory trace. (Author/RK)

Attempts to determine whether different types of MMPI (Minnesota Multiphasic Personality Inventory) profiles occur for heroin abusers and, if they existed, to describe them. (Author/RK)
