A longstanding and fundamental debate in developmental science is whether knowledge is acquired through domain-specific or domain-general mechanisms. To date, there exists no tool to determine whether experimental data support one theoretical approach or the other. In this article, we argue that the U- and N-shaped curves found in a number of…

Three experiments are reported on behavioral inference in children of 3 to 5 years of age. In each experiment the children learned two separate sequences of behavior which they were required to put together in the final test stage in order to obtain a reward. (MS)

This study examined children's use of category information as a discrimination cue to avoid intrusions in recall and false alarms in recognition of items outside given categories. Forty-eight children in grades 1 and 4 were administered one of three conditions of a recognition task in which all study words were members of one of two familiar…

Describes a study which used a discrimination-learning procedure to compare the ability of language-disordered and normal children to modify hypotheses. In a series of two-dimensional learning set and orthogonal problems, all children reached learning set criteria quickly; on orthogonal problems, language-disordered children performed…

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)

Reports three experiments to investigate differences in the semantic classification of pictures and words. The data suggest that visual short-term memory and semantic memory operate in semantic-decision tasks though these sources of information differ in characteristics, potential for activation, and level of abstraction.

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. (Editor)

Three studies of elementary school children's problem-solving procedures in intentional discrimination tasks are reported. Subjects were children selected from kindergarten and grades 2, 3, and 6. (Author/MP)
