Several studies on free recall suggest that processes responsible for recall are analogous to processes responsible for rehearsal. In children, the relationship between cumulative rehearsal and recall performance has been proven to be critical; however, the locus of the effect of rehearsal is not yet fully understood. To unfold the mechanisms that…

This study investigated the nature of resources involved in duration processing in 5- and 8-year-olds. The children were asked to reproduce the duration of a visual or auditory stimulus. They performed this task either alone or concurrently with an executive task (Experiment 1) or with a digit or visuospatial memory task (Experiment 2). The…

This experiment investigated the effect of the short-term retention of duration on temporal discrimination in 5- and 8-year-olds, as well as in adults, by using an episodic temporal generalization task. In each age group, the participants' task was to compare two successive durations (a standard and a comparison duration) separated by a retention…

Studied time estimation for a button-pressing response in 3- and 5.5-year-olds under "minimal,""temporal," and "force" instructions. Found that force--but not temporal--instructions improved 3-year-olds' timing accuracy. When instructed to press harder, they pressed longer. Older children were more accurate with…

Tested 3-, 5-, and 8-year-olds on temporal generalization with visual stimuli. Found increasing sharpness of generalization gradient with increasing age, and change from symmetrical to adult-like asymmetrical generalization gradients among 8-year-olds. Theoretical models attributed changes to increasing precision of the reference memory with…

This study tested 5- and 8-year-olds and adults in a bisection task with a sequence of stimuli in which time and number co-varied. Findings indicated that the number of stimuli interfered with 5-year-olds' performance on the temporal bisection task. Number interference decreased both with age and counting strategy. In the numerical bisection task,…

Examined the role of prior temporal knowledge of 4 1/2- and 6-year-olds through the use of high-rate, interval, and minimal instructions in a fixed-interval training schedule. Determined that the subjects' learning depended on their verbal self-control skills. (BC)

It has been suggested that there are systematic distortions in children's memory for temporal durations, such that children's memory is not just less accurate than that of adults but qualitatively different. Experiment 1 replicated the memory distortion effect by demonstrating developmental change in the tendency to confuse a reference duration…

Groups of 10 and 15 year olds were shown a capital letter visual stimulus followed by a masking grid pattern. Sensory transmission time was the same in both groups. Older children showed a greater rate of information accrual and a greater amount of information extraction than did members of the younger group. (BC)

Two experiments are presented which investigated the effect of retention interval and information load on short-term recognition memory in retarded subjects. (Author/SET)

Memory for object motion in three-month-old infants was investigated across different time intervals in three studies using a novelty preference method. Results indicated a significant preference for the novel motion after a one-minute delay, a significant preference for the familiar motion after a one-month delay, and no preferences at the…

In two experiments, children aged seven to nine years estimated the interval of time light bulbs illuminated with different intensities remained on. Results indicated that prospective estimates were longer than retrospective estimates and that children gave longer estimates when their attention was distracted from the estimation task than when it…

Four- to 11-year-olds made duration, distance, and speed judgments on Piagetian tasks where cars ran on parallel tracks. Among younger children, duration and distance judgments had approximately the same difficulty. Among older children, distance judgments were easier than duration judgments, and symmetry of effects of temporal and spatial…
