We explored whether a rising trend to blindly "overcopy" a model's causally irrelevant actions between 3 and 5 years of age, found in previous studies, predicts a more circumspect disposition in much younger children. Children between 23 and 30 months of age observed a model use a tool to retrieve a reward from either a transparent or opaque…

This investigation tracked changes in categorical bias (i.e., placing objects belonging to the same spatial group closer together than they really are) while 7-, 9-, and 11-year-olds and adults were learning a set of locations. Participants learned the locations of 20 objects marked by dots on the floor of an open square box divided into…

Investigated the specificity of reading-disabled children's deficits in working memory capacity. Found that reading-disabled 10-year-olds performed worse than normal-reading children, matched for chronological age and reading age, on all measures of working memory capacity. Their poorer performance seemed to be due to a general lack of capacity…

Two experiments, consisting of eight set operation tasks, were conducted to examine rule-learning in children. Subjects were 179 boys ranging in age from 7.9 to 15.4 years. (MP)

Dual task procedures--elaborative strategy use and finger tapping--were used to examine both recall and mental effort demands of elaboration strategy use among second and third graders. Results indicated that boys and girls did not differ in recall of arbitrarily paired items, but for feminine pairs, girls recalled more than boys; for masculine…

Three experiments demonstrated (1) habituation and long-term retention of habituation to a tone stimulus in third-grade children, (2) specificity of habituation to an auditory stimulus in first- but not fifth-grade children, and (3) specificity of habituation in fifth-grade children in response suppression when a cross-modality stimulus change was…

A complex task designed to elicit a variety of memorization strategies was presented to 236 children aged 10 to 14. (MP)

Describes research on young children's long-term memory under 2 conditions of acquisition: direct imitation followed by a 10-minute delay, or deferred imitation. Children were able to encode and retain as much from visual pickup of modeled acts as from feedback obtained through imitation. (Author/GH)

Examined the effect of functional values of stimuli on orienting response elicitation. Subjects were 50 4-month-old infants and were randomly assigned to 1 of 3 experimental conditions. Results suggested the importance of taking into account the functional value of stimuli when analyzing infant attention. (MOK)

Describes four experiments to show that the effects of item-specific and relational encoding emphasis on recall vary with the retrieval context for both young children and adults. (HOD)

Second-grade children were explicitly supplied with zero, one, two, or three components of information to specify the respective contributions of various sources and amounts of acquired strategy-utility information. Metacognitive knowledge was evidenced only when the training regiment included the complete set of critical metacognitive components.…

Evaluated the possibility that three-year-olds solve small-number conservation problems by an empirical procedure whereby the sets are quantified each time presented. Children chose the more numerous of two arrays, one containing two elements and the other three elements. Results disconfirmed claims that three-year-olds can conserve small numbers.…

To examine developmental aspects of auditory sensory memory, a series of experiments was conducted on the stimulus suffix effect with the primary variables being age of subject (7 and 11 years), rates of presentation, and length of list. Effects were nearly identical across age groups when a fast presentation rate was used. (Author/DB)

Focuses on the development of the executive monitoring function and addresses the question of whether a rehearsal strategy is used on two different tasks where such use is appropriate. Subjects were elementary and secondary school children and adults. (MP)
