Two studies involving learning disabled elementary students examined two procedures shown to facilitate concept acquisition among normal children: selection and sequence of positive and negative examples and analytic assistance during concept learning. Examples did not facilitate concept acquisition, and exposure to a simple strategy actually…

In three experiments, a multiple habituation paradigm was used to examine the ability of 7- and 9-month-old prelinguistic infants to form a natural, basic-level object category. Findings constitute independent evidence for the existence of a linguistically relevant nonlinguistic category prior to the onset of word comprehension. (SED)

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Examines kindergartners' and second graders' knowledge of concept attribute importance and the children's use of this knowledge to categorize. (HOD)

Describes four experiments that examined the ability of second- and fifth-grade children and college adults to use "extra-list" cues to retrieve episodic information from memory. Shows that effective cue use varied with both the "match" of cue and event classification, and with the associative structure of permanent memory.…

A longitudinal investigation on development of conservation skills in 31 learning disabled (LD) children suggested that delayed transition between preoperational and concrete operational thought may be an important factor in understanding the continued school failure of learning disabled children. (Author/CL)

Approximately 500 nonscience major university chemistry students were surveyed to record their interpretations of specific chemical symbolism before presenting modern concepts of atomic and molecular structure, in an attempt to understand the thought processes entering students use as they interpret symbolism. Results are reported and discussed.…

Article discussed the fact that children do not always learn what their teachers consider important, and also the problem that adults must understand somehow how children's minds work if they are to teach them successfully. (Author/RK)

Preschool children who did not group a set of geometric stimuli according to complete similarity on a pretest were taught classification wither in a modeling or in a reinforcement condition. Modeling was found to be an effective means of teaching classification behavior. (ST)

This study examined a category-induction'' manipulation which focused the attention of 40 preschoolers on categories through discussion and through spatial arrangement of items. This manipulation induced children's use of category questions. (ST)

This study is aimed at trying to discover the isolable characteristics of intelligence, of the kind of mental processes which result from it, and of the relationship between intelligence and the formation of concepts. (Author)

Students who viewed demonstrations or manipulated apparatus understood the relational concepts (of the form a/b = a'/b') of speed, force, and work better than a control group, but did not differ significantly from each other. (AL)

Level of cognitive development was not significantly related to humor appreciation for either novelty or incongruity humor in 30 boys at each of three age levels: 5, 7, and 9. (WY)
