Four-year-old boys and girls initially named and matched by form more often than by color. Also, agreements involving form names and matches occurred more often than agreements involving color names and matches. (Authors)

Results indicated that negative instances were an integral part of concept acquisiton. The relationship between the positive and negative instances was based upon similarity of irrelevant attributes and sentence difficulty. (Author)

With the advent of multi-screen capability in multi-media communication centers, it is possible to control the visual learning environment in a number of interesting ways. The basic assumption implicit in the concept of the multiple-image presentation is that it increases learning. A study tested the effect on learning of single- and…

An evaluation of selective generalization of habituation on the basis of meaningful categories of stimuli. Also explored are the sex differences in conceptual generalization of habituation. Subjects were 36 toddlers with a mean age of 40 months. (SDH)

Proposes explanations and further research considerations for the apparent psychological equivalence of the terms "complexity" and "novelty" as they refer to information theory, stimulus generalization, and subject expectancy effects. (RL)

Kindergarten and first grade children were trained to choose the middle-sized stimulus in either a single stimulus set or in each of two nonoverlapping stimulus sets. Findings were reported in terms of the assumption that cognitive processes are important in the intermediate-sized transposition paradigm. (Author/DB)

To the authors' knowledge, this is the first conclusive demonstration that an observer's spontaneous verbalizations can interfere with vicarious rule learning. (Authors)

This study, which indicates that both age and variation in training affect children's concept formation, provides a basis for explaining the effect of age. Sixty-four 4- and 5-year-olds learned three novel concepts (animal-like, plant-like, and machine-like). Subjects were presented with either four different examples of each concept (multiple…

To the authors' knowledge, this is the first demonstration that from observation alone, unaided by other means of conveying information, a concept can be retained and generalized to novel stimuli after a substantial elapse of time. (Authors/MB)

Looking times of 36 children were recorded during subject-controlled presentation of slides in order to determine whether the existence of simple categories in 3-year-olds can be inferred from habituation data, and to determine any sex differences in conceptual generalization of habituation. Habituation was demonstrated over repeated presentation…

The purpose of this study was to determine the effects of age differences and differences in memory load on concept identification (CI) tasks of varying levels of complexity. Previous studies with young children found increasingly better performance on CI tasks with increasing age. This was in part due to the fact that older subjects categorize…

The term, "schema," used largely as a descriptive convenience rather than a theoretical guidepost in social psychology is examined through an analysis of its development, function, and structure. This paper articulates a model of schema development in adults by defining a schema as a representation of some stimulus domain and a set of…

This study analyzes the generalization abilities of children with reading disabilities by comparing the performance of such children with that of a normal control group on a conditional discrimination learning-set task. Both groups, consisting of boys aged eight to ten, participated in the Wisconsin General Test Apparatus in a form modified for…

This investigation compares overt judgments about tenable hypotheses to choices in a concept identification task, as a function of stimulus similarity on successive trials. Two mathematical models are tested: (a) A 1-element local consistency version of Restle's concept identification model and (b) the same model with two additional passive states…
