Two experiments investigated the ability of 3-month-olds to acquire generalized expectancies of reward and the role of these expectancies in memory retrieval. In both experiments, infants exhibited positive transfer over invariant and variable stimulus series; however, in the second experiment, violations of either expected order produced a…

The interactive effects of physiological reactivity and social support on children's memory were examined. Four- to 6-year-olds completed a laboratory protocol during which autonomic responses and salivary cortisol were measured. Memory was assessed shortly afterward and 2 weeks later. During the second interview, children were questioned by a…

The current study addressed how the timing of interviews affected children's memories of unique and repeated events. Five- to six-year-olds (N = 125) participated in activities 1 or 4 times and were misinformed either 3 or 21 days after the only or last event. Although single-experience children were subsequently less accurate in the 21- versus…

Developmental differences in references to temporal attributes of allegedly experienced events were examined in 250 forensic interviews of 4- to 10-year-old alleged victims of sexual abuse. Children's ages, the specific temporal attributes referenced, and the types of memory tapped by the interviewers' questions significantly affected the quantity…

Examined the effects of age, repetition, and retention interval on children's memory of the final occurrence of a repeated event. Found that repetition increased the number of items recalled, and that younger children showed a poorer ability to discriminate between the occurrences than the older children, though age differences were less evident…

This study examined whether the quality of first graders' (mean age = 7.2 years) numerical magnitude representations is correlated with, predictive of, and causally related to their arithmetic learning. The children's pretest numerical magnitude representations were found to be correlated with their pretest arithmetic knowledge and to be…

Describes three delayed-response experiments which tested two- and three-year-old children's memories for location of a hidden object under several combinations of spatial and pictorial cue availability and emphasis. (Author/JMB)

Two experiments with 18-week-old infants employed an interference paradigm to study infant visual memory for faces. (Author/JMB)

In a free-recall task, sixth graders were given instructions to rehearse aloud either actively or passively and were exposed to materials which differed in terms of the presumed salience of the list organization. Results showed that recall varied as a function of list organization under both types of rehearsal. (Author/JMB)

Forgetting, as defined by Piaget as Stage IV error, was studied in infants. Results partially support Piaget's hypothesis. (ST)

After studying photographs of real-world scenes, kindergartners, fourth graders, and adults were tested on their recognition memory in the landmark-in-context condition. For testing, the original scenes were paired with three types of foils: different landmark/different context, different landmark/original context, and original landmark/different…

Two-year-old children's memory for locations of hidden objects was examined in four cue conditions. Pictures marked hidden-object locations in three of these conditions, and either depicted or were related associatively to hidden objects. In the fourth condition, only blank cards were presented with the objects. (Author/SS)

A series of free-recall experiments was conducted in which preschool children were tested repeatedly over many sessions. Various experimental manipulations were interspersed with baseline sessions along the lines of the single-subject design commonly used in free-operant studies. (Author/JMB)

Infants were trained to kick their feet into a crib mobile and tested two weeks later. Found that presentation of a moving, but not a stationary, mobile in a reminder treatment 24 hours before testing alleviated forgetting in the test and that, in the test, memory of the kicking activity was specific to the conditions of the original training. (BC)

Findings reveal that memory retrieval at six months of age is highly specific to the setting in which the memory is acquired. This suggests that infants learn what events are associated with what places before they are able to locomote independently and acquire a spatiotemporal map of the relations between those places. (RH)
