It is generally assumed that slowing after errors is a cognitive control effect reflecting more careful response strategies after errors. However, clinical data are not compatible with this explanation. We therefore consider two alternative explanations, one referring to the possibility of a persisting underlying problem and one on the basis of…

Nine-month-olds can respond to a change in rhyme when the conditioned head turn procedure is used [Hayes, R. A., Slater, A., & Brown, E. (2000). "Infants' ability to categorise on the basis of rhyme." "Cognitive Development, 15," 405-419]. However, it is not known whether infants are detecting the change in vowel, the change in coda, or both. In…

Four- to 10-year-old children (n = 50) participated in a 2D search task that included geometry (with- and without lines) and feature conditions. During each of 27 trials, participants watched as a cartoon character hid behind one of three landmarks arranged in a triangle on a computer screen. During feature condition trials, participants could use…

Research has demonstrated that differential parental scaffolding utterances influence children's development of executive function. Traditional conceptualizations of scaffolding, though, have difficulty in explaining how such differential effects influence children's cognitive development; they do not account for the timing of parental utterances…

This study examined the prevalence and determinants of spanking of children at 3?years of age and the associations between spanking and externalizing behaviour and receptive verbal ability at age 5?years. Overall, we find maternal spanking rates of 55.2% and paternal rates of 43.2% at age 3?years. Mothers facing greater stress and those who…

Alumni self-ratings of their personal growth were linked to their intellectual development during college four to seven years earlier. Graduates that were satisfied with their personal growth in the arts, creative thinking, making logical inferences, learning independently, exercising initiative, and tolerating other points of view had higher…

Raising a child with a disability often makes it difficult to find child care. Many families learn that child care programs are simply unable to meet the special needs of their children, while specialized facilities have limited space, and specialized private care is expensive. To meet the needs of all children, Head Start and Early Head Start…

I focus on the role of preschool intervention and developmental psychology researchers in defining the concept of the "disadvantaged child" and in designing and evaluating remedies to alleviate educational "disadvantages" in young children. I argue that preschool interventions concentrated especially on compensating for…

While early childhood education has received increasing attention in the developing world in recent years, relatively little evidence is available from sub-Saharan Africa on its effects on child development and subsequent school enrolment. We use a prospective case-control design to evaluate the developmental impact of a community-based early…

Educators and policymakers have been concerned about the problem of early literacy performance for many decades. Despite educational reform to increase standards, many children consistently fail to read at levels that enable them to compete globally. The purpose of this study was to provide a data driven program evaluation of a reading…

In the 1998 reauthorization of Head Start, Congress mandated that the US Department of Health and Human Services (DHHS) determine, on a national level, the impact of Head Start on the children it serves. As noted by the Advisory Committee on Head Start Research, this legislative mandate required that the impact study address two main research…

The purpose of this study was to examine how the infusion of theatre arts into the language arts and social studies curricula in grades 4 and 5 impacted the cognitive and prosocial development of special populations, as well as the students' attitudes toward learning. An experimental/control group design was employed. Various instruments were used…

Researchers studied components of a two-year school-wide Striving Readers intervention aimed at bolstering middle school teachers' use of literacy strategies to raise students' reading achievement. Although students of intervention teachers had significantly higher Iowa Test of Basic Skills (ITBS) scores than students of non-participating…

Jaak Panksepp, known best for his work on animal emotions and coining the term "affective neuroscience," investigates the primary processes of brain and mind that enable and drive emotion. As an undergraduate, he briefly considered a career in electrical engineering but turned instead to psychology, which led to a 1969 University of…

This study examined contributions of maternal personality and infant temperament to infant vocabulary and cognitive development both directly and indirectly through parental stress. Participants were recruited at birth and included 63 infant twin pairs and their mothers. Assessments were completed at 6, 9, 12, and 18 months of age and included…
