The ability to use knowledge to guide the completion of goals is a critical cognitive skill, but 3-year-olds struggle to complete goals that require multiple steps. This study asked whether 3-year-olds could benefit from "plan chunking" to complete multistep goals. Thirty-two U.S. children (range = 35.75-46.59 months; 18 girls; 9 white,…

Children are on a quest for knowledge. To achieve it, children must integrate separate but related episodes of learning. The theoretical model of memory integration posits that the process is supported by component cognitive abilities. In turn, memory integration predicts accumulation of a knowledge base. We tested this model in two studies (data…

The hypothesis that language plays a role in theory-of-mind (ToM) development is supported by a number of lines of evidence (e.g., H. Lohmann & M. Tomasello, 2003). The current study sought to further investigate the relations between maternal language input, memory for false sentential complements, cognitive flexibility, and the development of…

The neurodevelopmental sequelae of early deprivation were examined by testing (N = 132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized…

This study assessed executive function and mental state understanding in Korean preschoolers. In Experiment 1, forty 3.5- and 4-year-old Koreans showed ceiling performance on inhibition and switching measures, although their performance on working memory and false belief was comparable to that of Western children. Experiment 2 revealed a similar…

Infants exposed to a set of artificially-created face stimuli having distinct mean and modal prototypes showed a pattern of behavior predicted by category abstraction models. Infants appeared to abstract, at the time of learning, a feature-count summary of the category displayed. (Author/RH)

Investigates the nature of and changes in early memory demands and assesses the relationship between memory demands and memory performance among 10 children 30 and 42 months old and their mothers. Results suggested that mothers' memory demands have an impact on children's memory performance--providing at least partial support for Vygotsky's…

Children four and five years of age were shown photographs of persons with whom they were familiar in varying degrees and asked to recall depicted persons' names. When subjects could not name, feeling-of-knowing judgments and judgments about whether subjects had seen the depicted person were obtained. Both judgment types predicted recognition…

Examines the performance on verbal, nonverbal, and memory tasks of 11 girls (ages 8 to 11 years) identified as having an extra X chromosome at birth. Results showed that the triple-X girls were markedly inferior in their performance on the tasks, indicating a rehearsal deficit, an inability to use list structures, and weaker language skills.…

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…

Two experiments investigated 18- to 30-month-old children's memory for the location of a hidden object. Memory performance was significantly better when the object was hidden within the natural environment as opposed to when hidden in a set of boxes. Older subjects effectively used a landmark cue as a memory aid. (Author/RH)

Examines the role of basic cognitive-processing efficiency as the source of developmental variance in cognitive performance. Two experimental tasks, memory and visual scanning, were used to investigate age effects on the search-processing parameter. Subjects were 9-, 11-, 13-, and 15-year-old children. (CM)

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.…

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

Examined children's recall of the spatial configurations of an environment after the children followed prearranged paths and encountered barriers to movement. When asked to reconstruct the environmental configuration from memory, males estimated distances more accurately than did females. No age differences were noted. (Author/DB)
