HIV-exposed uninfected (HEU) children during the preschool and early school ages may be at-risk for neurodevelopmental challenges due to in utero and perinatal exposure to HIV and/or antiretroviral (ARV) medications. HEU children and HIV-unexposed uninfected (HUU) children from the community were recruited and tested at 3 to 4 and 5 to 6 years of…

Differentiation of intelligence refers to changes in the structure of intelligence that depend on individuals' level of general cognitive ability (ability differentiation hypothesis) or age (developmental differentiation hypothesis). The present article aimed to investigate ability differentiation, developmental differentiation, and their…

There are many reasons to be curious about the way people learn, and the past several decades have seen an explosion of research that has important implications for individual learning, schooling, workforce training, and policy. In 2000, "How People Learn: Brain, Mind, Experience, and School: Expanded Edition" was published and its…

This paper reviews the recent literature on the production of skills of young persons. The literature features the multiplicity of skills that explain success in a variety of life outcomes. Noncognitive skills play a fundamental role in successful lives. The dynamics of skill formation reveal the interplay of cognitive and noncognitive skills, and…

In his work as a family therapist and researcher with children and families in educational and community settings, the author encounters children who are anxious, depressed, lacking in empathy, self-esteem and motivation, and naive in their expectations about their physical and mental abilities. They haven't been properly challenged. These kids…

Over the last few decades, long-term survival rates of children diagnosed with the two most common forms of childhood cancer, acute lymphoblastic leukemia (ALL) and brain tumors have improved substantially. Neurodevelopmental and psychosocial sequelae resulting from these diseases and their treatment have a direct impact on the developing brain…

A total of 48 Canadian, middle-class 3-year-olds participated in a study of their abilities to predict the actions of a story character with a false belief and a story character engaged in pretence. In the experimental situation, a red puppet with pen-markers for legs left an "inky trail" to the location of a hidden treasure in one of…

Imitation by infants functions in two ways: (1) to help the individual understand a puzzling event, and (2) to indicate mutuality with another person. Although changes in cognitive understanding influence the course of imitation, the occurrence of imitation in specific situations may be governed by the interplay of the two functions that imitation…

Notes that Halford's book does not really address children's own understanding but rather the psychologist's attempt to understand children from the outside. Discusses the five major sets of ideas at the core of Halford's explanations of capacity, complexity/dimensionality, development, and learning. Examines two arguments against Halford's…

A series of experiments investigated 5- to 17-month-olds' comprehension of adults' direction of gaze and manual pointing behaviors. Findings indicated that a change in the adult's direction of gaze and orientation of head does not seem sufficient to enable the infant to reliably localize a referent when the infant must choose between pairs of…

Does not support the hypothesis that cognitive regression takes place as a part of normal aging. (RL)

There is an assumed relationship between a person's self-esteem, speech anxiety, and low cognitive complexity, but further research is needed for support of this premise. An important question to explore is how a child with speech anxiety (lack of confidence in communication situations) perceives others. Based on balance theory, the answer is that…

This study tested the hypothesis that social competence of mother-infant play reflects both secure mother-infant attachment and more advanced cognitive development. Subjects were 58 toddlers between 16 and 19 months of age and their mothers. Two general methods were used: observation and maternal report. Standardized developmental assessments were…

Mothers were asked to predict their children's responses to standardized intelligence test items. Negative correlation was expected between inaccurate maternal knowledge of children's ability and degree of children's psychological development. False maternal predictions correlated - .80 with correct children's responses. Nearly all of the…
