Semantic and contextual cuing of preschool children's recall.

3 experiments were carried out to investigate cuing of young children's recall. In each experiment younger (3 years) and older (4 1/2 years) preschool children were tested on free and cued recall tasks in which the presence of semantic and contextual cues was manipulated. In the first 2 experiments there was little evidence that the children's recall was facilitated by presence of contextual cues, independent of the facilitation produced by semantic information. In the third experiment, context and target items were integrated experimentally at presentation. In this case, unrelated context cues improved recall. This finding suggests that limitations in the facilitatory effects of context cues for preschool children are related to the ways these young children initially encode target and context items. In all 3 experiments semantic cues aided both younger and older children's recall. Moreover, there was evidence of a developmental increase in the effectiveness of semantic, but not contextual, cues. This finding highlights the importance of growth of the semantic knowledge base for early memory development.

Child Development

Memory of historical events.

Younger (mean age = 20) and older (mean age = 64) adults were asked to recall the dates and make recency judgments for historical events that occurred in each of three time periods between 1862 and 1977. Overall there were no age differences in either the number of correct dates or the number of correct recency judgments. However, younger adults tended to perform better than older adults on events that occurred most recently, and performed significantly better on events that occurred during the respective times of their youth. In addition, somewhat different patterns of performance on the two dependent measures suggested that detailed information about events is lost with time, but that more general information may not decline with time.

Adolescent

Age differences in the consistency of adults' associative responses.

Younger (mean age = 20) and older (mean age = 63) adults were asked to produce free associations to the same list of 24 verbal stimuli on each of four trials. Older adults tended to produce less common associations and their associations were less consistent across trials. Possible relationships between older adults' inconsistency in processing and their (a) poorer memory performance and (b) slower reaction times were discussed.

Adult

Age differences in adults' free recall, cued recall, and recognition.

Adults in their twenties and sixties were tested for free recall, cued recall, and recognition of words that they had studied in an intentional memory task or generated associations to in an incidental orienting task. Significant age-related declines in performances on intentional items were observed regardless of type of memory test. Significant age-related declines in performance on incidental items were also observed on free and cued recall tests; however, age differences on incidental items were attenuated on cued recall tests, and they were eliminated on recognition tests. In addition, while younger subjects profited more from retrieval cues that were associations they had themselves generated than from retrieval cues that were normed common associations, older subjects made comparable use of these two cue types.

Adult

Young children's coding and storage of visual and verbal material.

36 preschool children (mean age 4.2 years) were each tested on 3 recognition memory lists differing in test mode (visual only, verbal only, combined visual-verbal). For one-third of the children, original list presentation was visual only, for another third, presentation was verbal only, and the final third received combined visual-verbal presentation. The subjects generally performed at a high level of correct responding. Verbal-only presentation resulted in less correct recognition than did either visual-only or combined visual-verbal presentation. However, because performances under both visual-only and combined visual-verbal presentation were statistically comparable, and a high level of spontaneous labeling was observed when items were presented only visually, a dual-processing conceptualization of memory in 4-year-olds was suggested.
