Age-related differences in imitation and recall were studied in children ranging from preschool to college age. Results indicated that children were more sensitive to vicarious consequences than adults. (ST)

Immediate memory spans for alphabetic items were studied in elementary school children and adults. Results indicated that immediate memory span increases with age and practice. (ST)

Information processing capabilities of normal and retarded individuals were studied within the context of a modified Steinberg recognition memory task. Normal and retarded individuals spent the same amount of time learning information, but normal subjects spent less time retrieving the information. (ST)

Six-month and 12-month-old infants were studied for wariness (hesitancy to approach new and incongruous stimuli). Both age groups could perceive differences in stimuli, but only the older infants displayed wariness. (DP)

Investigated whether children will relinquish belief in Piagetian concepts upon presentation of disconfirming evidence. The conservation of weight concept extinguished more readily than transitivity of weight, and only for the latter was a developmental trend evident. (DP)

Two experiments examined imagery as a factor in children's learning to associate pairs of objects. Presenting objects in an interacting fashion facilitated recognition, and indicated that children can be trained to form their own interaction images. (DP)

Coding and recoding of hypothesis information was studied with college students and third, fifth, and seventh graders. Deficiencies in young children's ability to code, but not recode, contributes to their less efficient performance on discrimination problems. (DP)

Infants 21- to 25-weeks-old devoted more visual fixation to novel than familiar stimuli on immediate and delayed recognition tests. The experiments confirm the existence of long-term recognition memory for pictorial stimuli in the early months of life. (DP)

Investigated effects of dimensional dominance of stimuli and subject's ages in initial and shift learning of discrimination tasks. (DP)

Preschool children were trained on a color relevant oddity problem by one of 3 methods: (1) increased salience of the oddity relationship, (2) instruction on solution rule, or (3) a combination of both. Generality of results were probed with a form-relevant transfer problem. (DP)

Investigated changes in non-nutritive sucking behavior of premature infants when light stimulation was presented. Results generally support past evidence that premature infants are capable of making orienting and discriminative responses to visual stimuli and chronological age effects were indicated. (DP)

The relative effectiveness of reward and punishment on the development of response inhibition was evaluated developmentally with kindergarteners and second graders. Removal of positive reinforcers was apparently more effective than reward in producing inhibiting at both age levels. Transfer of inhibition training was also evaluated. (DP)

Subjects in three age groups judged absolute and relative frequencies of pictures and words presented in lists. There was relatively greater improvement with age in judgment of pictorial stimuli. Study results lend support to the frequency theory of discrimination learning. (DP)

In contrast to predictions of the information analysis approach, the amount of vicarious consequences did not affect preschoolers' recall of modeled behavior, while the type of vicarious consequences did have a differential effect. (DP)

Three experiments were conducted with elementary school students which investigated whether modelling of unreinforced behavior influenced children to perform that behavior. Results indicated that the unreinforced behavior of the model serves both as a source of information and as a cue for unreinforced imitation. (DP)
