Children's testimony: a review of research on memory for past experiences.

This review of children's testimony focuses on research related to memory for past experiences. The aspects of the memory system that are involved in testimony are discussed and the development of autobiographical memory is examined. Relevant research findings are summarized in the context of an information-processing model of memory and the implications of this work for clinical practice are outlined. We conclude that (1) under certain conditions, even very young children can remember and report past experiences with some accuracy over very long periods of time; (2) substantial and significant developmental differences have been demonstrated in children's abilities to provide eyewitness testimony; (3) children can be influenced in a variety of ways to provide complete and elaborated reports of events that never occurred; and (4) even experts cannot always tell the difference between true and false reports.

Acting out the details of a pediatric check-up: the impact of interview condition and behavioral style on children's memory reports.

This investigation was designed to determine whether an enactment interview condition involving a doll and props, in contrast to a verbal interview, would enhance 3- and 5-year-olds' (N = 62) recall of a pediatric examination. An additional aim was to explore the influence of behavioral styles and language skills on children's performance, and the extent to which these relations varied by age and interview condition. Both 1- and 6-weeks following their check-ups, the children in the enactment condition, particularly the 3-year-olds, provided more spontaneous, elaborate reports than did those assessed with a verbal protocol. Nonetheless, enactment also resulted in increased errors by the 3-year-olds at the first interview, and by children in both age groups after the 6-week delay. The age and interview condition effects, however, were moderated by the children's behavioral characteristics. Among the younger children, a measure of manageability predicted performance in the enactment setting, whereas an indicator of persistence was associated with recall in the verbal condition. The results have implications for an understanding of children's memory of events and of their ability to provide testimony in legal settings.

Means to the goal of remembering: developmental changes in awareness of strategy use--performance relations.

We examined awareness of the causal relation between strategy use and recall performance among preschoolers, first graders, and third graders, and the relation of this awareness to children's study behavior and recall. In session 1, children were presented with two study-recall trials; the second trial included questions concerning the child's study behavior. During Session 2, children viewed videotapes in which a model's strategy use (labeling versus no labeling) and recall level (high versus low) were varied orthogonally. Children judged whether the model tried to remember, rated how hard the model tried to remember, and described how they knew. Children who gave mentalistic explanations for their study behaviors in Session 1 recalled more than those giving nonmentalistic explanations. In Session 2, age-related differences were observed in awareness of the relation between strategy use and performance level. Further, children who demonstrated understanding of strategy use-performance relations in Session 2 were more likely to give mentalistic explanations for their own study behaviors in Session 1. The results further delineate the metamemorial development that contributes to effective strategy utilization.

Young children's long-term retention of a pediatric examination.

Children at ages 3, 5 and 7 (N = 187) provided reports of their physical examinations immediately following the checkup and after a delay of either 1, 3, or 6 weeks, or only after 3 weeks. The protocol used for all interviews consisted of initial general prompts, followed by increasingly specific questions as needed. Recall of standard features of the examinations was scored, along with responses to questions concerning acts that did not occur. Retention of the event was extensive and accurate. Although clear age effects were observed in recall, the delay interval did not strongly affect performance over the 6-week period. The amount of forgetting was significant at ages 3 and 5, but not at age 7. With increasing age, a greater percentage of the features was spontaneously recalled. When presented with incongruous questions, all children evidenced rates of correct denials that exceeded chance and few errors of commission. The initial interview did not affect delayed recall. Implications for children's testimony are discussed.

The expression of memorization in early childhood.

This experiment examined the expression and effectiveness of memorization in young children. Sixty children at each of the ages 4, 5, and 6 were randomly assigned to a memory group or to one of two control groups. All of the children were told that they could play with a group of toys during a brief activity period; the children in the memory condition were also instructed to memorize a specified subset of the toys. Mnemonic mediators were identified on the basis of differences in the activity period behaviors of children given memory and play instructions. Relative to the children in the play groups, the children in the memory conditions played with the toys less; further, their use of naming and visual examination as mnemonic mediators differentiated the groups at all ages and increased with age. Only the oldest subjects given memory instructions, however, demonstrated superior recall. The relationships between activity period behavior and recall among the different conditions were explored with regression techniques. although previous research has focused on identifying the earliest use of memory strategies, the present findings underscore the importance of examining the development of these skills.
