Measures of prenatal exposure in 123 infants to polychlorinated biphenyls (PCBs), cord serum PCB level, and maternal report of contaminated fish consumption predicted less preference for a novel stimulus on Fagan's test of visual recognition memory (VRM) at 7 months. Preference for novelty decreased in a dose-dependent fashion and postnatal…

While six- and nine-year-olds were as good as adults in distinguishing what they did from what they saw someone else do, children had particular trouble across a range of actions in distinguishing actual from imagined doing. All subjects recalled actions according to performer; organization by person categories reduced clustering based on action…

Investigates strategies of 10-year-olds and 14-year-olds in tasks requiring prospective memory. Subjects were instructed to perform activities after waiting 30 minutes. As predicted, strategic time-monitoring occurred more frequently in the home than in the laboratory. Emphasizes the power of the laboratory as a contrasting context for…

The dependence of immediate, short-term and long-term reproductive memory on operative understanding was studied in elementary school students. Results are interpreted in terms of Piaget's theory. (ST)

This study investigated the hypothesis that as children become older they are increasingly likely to make efficient use of accessible retrieval cues. Results confirmed the hypothesis. (ST)

It was concluded that age and IQ have strong influences on acquisition-retrieval, but that forgetting rate is independent of these variables. (Author)

Findings are interpreted in terms of search strategy and memory. (Authors)

In order to determine whether non-Western children would show a memory deficit for contextually organized spatial ability, the performances of 30 Mayan and 30 American nine-year-olds on reconstruction of an organized three-dimensional miniature scene were examined. (MP)

Experiment I establishes that the ability to remember the slope of a line develops between three and four years of age. In Experiment II, 15 children with a mean age of four years and six months who had discriminated both slope and left-right problems under successive presentation were tested on these same discriminations under simultaneous…

The present study was designed to determine whether a reactivation procedure (consisting of the experimenter's manipulation of a previously experienced overhead crib mobile) would alleviate infant's poor retention after a 14-day interval. It is concluded that forgetting by young infants may result from failures in retrieval, and not failures in…

In three experiments, three- and four-and-a-half-year-old preschool children were tested on free and cued recall tasks in which semantic and contextual cues were manipulated. When context and target items were integrated experimentally at presentation, unrelated context cues improved recall. A developmental increase in the effectiveness of…

Twenty-five one-year-olds were administered two tasks (each of which consisted of a familiarization stage followed by a recognition stage) in order to determine whether infants can recognize the shapes of objects by touch alone. (CM)

In Experiment I, 24 preschoolers were tested on left-right, vertical-horizontal, and mirror-image oblique discriminations under essentially context-free conditions. Experiment II contrasted children's performance under context-free conditions with their ability to discriminate orientation in the presence of external visual cues. (RH)

Reports the findings of a series of long-term maintenance tests and a generalization phase given to a group of educable mentally retarded children more than one year after they were trained to use self-checking routines for estimating test readiness. (JMB)
