Infants were tested in three studies of the acquisition and long-term retention of category-specific information. Results document retention of category-specific information after intervals of two weeks. (PCB)

Assessed the effect of the amount of physical detail in pictures on the picture recognition memory of 7- and 9-year-olds, young adults, and adults over 68. For each age group, recognition accuracy was significantly higher for pictures presented in the simple rather than the complex form. (PCB)

Explored influence of changes in kindergartners' knowledge about a protagonist on earlier constructed memories of the story. Found that children's story recall was affected by their prior impressions. Following the second knowledge manipulation, children revised story reports consistent with newly acquired impressions, suggesting that they had…

Three studies, involving 72 3-month-old infants, demonstrated that infants remembered some of the original feature combinations of a mobile they had been trained to activate for up to 3 days but forgot all of them after 4 days. Even after 4 days, however, infants remembered the individual features that had entered into the original combinations.…

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…

Examined relationship between mother-child conversational interactions when children were 30, 36, and 42 months old and children's recall of these activities 1 day and 3 weeks later. Found that at all ages, features of activities jointly handled and jointly discussed were remembered better than features jointly handled but discussed by mother only…

Investigated the relationship of two memory components involved in the retrieval of information from long-term memory--one process-oriented and one structure-oriented-- to variability associated with age and ability differences. Striking developmental differences obtained for retrieval efficiency were highly related to scores on tests of ability,…
