Two experiments examined the development of the ability to encode, maintain, and update integrated representations of occluded objects' locations and featural identities in working memory across toddlerhood. Sixty-eight 28- to 40-month-old US toddlers (13 Asian or Pacific Islander, 6 Black, 48 White, 1 multiracial; 40 girls; tested between…

Memory decision-making in 26- to 32-month-olds was investigated using visual-paired comparison paradigms, requiring toddlers to select familiar stimuli (Active condition) or view familiar and novel stimuli (Passive condition). In Experiment 1 (N = 108, 54.6% female, 62% White; replication N = 98), toddlers with higher accuracy in the Active…

Comparisons of cognitive processing in monolinguals and bilinguals have revealed a bilingual advantage in inhibitory control. Recent studies have demonstrated advantages associated with exposure to two languages in infancy. However, the domain specificity and scope of the infant bilingual advantage in infancy remains unclear. In the present study,…

Dynamic relations during the preschool years across processes of control and understanding in the domains of emotion and cognition were examined. Participants were 263 children (42% non-White) and their mothers who were seen first when the children were 3 years old and again when they were 4. Results indicated dynamic dependence among the…

Executive control (EC) is related to mathematics performance in middle childhood. However, little is known regarding how EC and informal numeracy differentially support mathematics skill acquisition in preschoolers. A sample of preschoolers (115 girls, 113 boys), stratified by social risk, completed an EC task battery at 3 years, informal numeracy…

Distinctiveness effects in children's (5-, 7-, and 11-year-olds) false memory illusions were examined using visual materials. In Experiment 1, developmental trends (increasing false memories with age) were obtained using Deese-Roediger-McDermott lists presented as words and color photographs but not line drawings. In Experiment 2, when items were…

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)

Reports four experiments in which infants' recognition memory (defined by novelty preferences) was found to be improved by providing five- to seven-month-old infants with discriminable but related targets during the familiarization period. Facilitation of recognition was found for both photographs of faces and abstract patterns. (JMB)

In three studies, 12-month-old infants were familiarized either tactually or visually with objects and were then tested for visual recognition memory using either (1) the familiar and a novel object, (2) colored pictures of the objects, or (3) outline drawings of the objects. (Author/MP)

Results of three experiments suggest that groups of schizophrenic, younger normal, and older normal children used a serial information-processing strategy while performing on a partial report version of a span of apprehension task. Impairment of schizophrenic children on the partial report versions seemed to reflect inefficiencies in the…

A probe-type serial memory task was used to determine whether 3-dimensional objects would produce better recall than colored pictures of the same objects in elementary school students with low IQ's. (ST)

This study investigated 17-week-old infants' response to discrepancy in visual patterns as a function of rate of habituation. (BRT)

The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing…

A serial recognition task was used to compare performance of two age groups of learning disabled children (mean chronological ages 8.1 and 10.6) with 2- and 3-dimensional representations of nonlabeled 8-point random shapes. (Author/JMB)
