Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but…

Early-life exposures are critical for later child cognitive development. McCarthy Scales of Children's Abilities (MSCA) were used to assess cognitive development of 700 preschoolers (M[subscript age] = 4.2 years), derived from the "Rhea" birth cohort, in Greece. Principal component analysis (PCA) was applied on prospectively collected…

Cognitive deficits have been reported in children who experienced early neglect, especially children raised in institutionalized settings. Previous research suggests that early neglect may differentially affect the directional organization of white matter in the prefrontal cortex (PFC). This may be one mechanism to explain cognitive deficits…

Early life events can exert a powerful influence on both the pattern of brain architecture and behavioral development. In this study a conceptual framework is provided for considering how the structure of early experience gets "under the skin." The study begins with a description of the genetic framework that lays the foundation for brain…

The capacity to imitate facial gestures is highly variable in rhesus macaques and this variability may be related to differences in specific neurobehavioral patterns of development. This study evaluated the differential neonatal imitative response of 41 macaques in relation to the development of sensory, motor, and cognitive skills throughout the…

In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent-infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy…

Mothers read stories to their children (N = 41) aged between 3.3 years and 5.11 years old, and children then completed two false-belief tasks. One year later, mothers read a story to 37 of those children who were also given four tasks to assess their advanced understanding of mental states. Mothers' early use of cognitive verbs in picture-book…

The ability of 96 children (five, eight, and 12 years old) to nominate strategic social action that would alter a peer's ongoing emotional state was examined. Nominated strategies were appropriate to the emotional state to be altered; a shift with age from material intervention strategies to strategies involving verbal intervention or helping was…

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Explored in 2 studies 3- and 4-year-olds' understanding that the 5 senses can each lead to different types of knowledge. Found that 3-year-olds performed significantly poorer than 4-year-olds on all tasks, suggesting a marked transition in children's ability to recognize the origin of their modality-specific knowledge between 3 and 4 years.…

Investigates the relationship between children's cognitive and affective processes in 30 four and five year olds who were interviewed individually to probe affective understanding, administered a series of Piagetian tasks, and given the Peabody Picture Vocabulary Test. Performance on affective and cognitive tasks correlated significantly.…

Deaf children, seven to thirteen years old, were observed on concrete, transitional and formal operational tasks ranging from dual classification to combinatorial reasoning. Results were related to number of years of schooling. (ST)

Measured the effect of schooling on cognitive skills by comparing the performance of 230, 6-13-year-old Hausa school children on a variety of cognitive tasks to that of 175 like-aged Hausa children who did not attend school. (Author/SDH)

Results of two studies suggested that acquisition of route mapping during the preschool years provides a means of organizing spatial information and internal representations necessary for successful problem solving in general. (Author/RH)
