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…

Breit, Moritz; Brunner, Martin; Preckel, Franzis – Developmental Psychology, 2020
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…

Estrada, Eduardo; Ferrer, Emilio; Shaywitz, Bennett A.; Holahan, John M.; Shaywitz, Sally E. – Developmental Psychology, 2018
Identifying change at the individual level is an important goal for researchers, educators, and clinicians. We present a set of statistical procedures for identifying individuals who depart from a normative change. Using Latent Change Scores models (LCS), we illustrate how the Individual Likelihood computed from a statistical model for change…

Chen, Zhe; Honomichl, Ryan; Kennedy, Diane; Tan, Enda – Developmental Psychology, 2016
The present study examines 5- to 8-year-old children's relation reasoning in solving matrix completion tasks. This study incorporates a componential analysis, an eye-tracking method, and a microgenetic approach, which together allow an investigation of the cognitive processing strategies involved in the development and learning of children's…

Pochon, Régis; Declercq, Christelle – Journal of Intellectual & Developmental Disability, 2013
Background: According to the literature, children with Down syndrome (DS) have difficulties recognising facial expressions. Yet abilities to recognise emotional expressions are often assessed in tasks that imply comprehension of words for emotions. We investigated the development of these abilities in children with DS in a longitudinal study that…

McArdle, John J.; Grimm, Kevin J.; Hamagami, Fumiaki; Bowles, Ryan P.; Meredith, William – Psychological Methods, 2009
The authors use multiple-sample longitudinal data from different test batteries to examine propositions about changes in constructs over the life span. The data come from 3 classic studies on intellectual abilities in which, in combination, 441 persons were repeatedly measured as many as 16 times over 70 years. They measured cognitive constructs…

Kanaya, Tomoe; Ceci, Stephen J.; Scullin, Matthew H. – Intelligence, 2005
Age differences within the yo-yo trend in IQ, caused when aging norms that produce inflated scores are replaced with new norms, were examined using longitudinal WISC, WISC-R and WISC-III records of students tested for special education services from 10 school districts. Descriptive and individual growth modeling analyses revealed that while the…

The author reviews cross-sectional and longitudinal studies on the status of intelligence in the aging, and finds conflicting conclusions: (1) intelligence does decline as persons grow older; (2) only some aspects decline while others improve; and (3) intelligence does not decline. Certain factors are adduced to suggest that such…

This paper is a preliminary report of a project designed to determine the family and other environmental factors which are associated with effective functioning in children from low income environments. The purpose of the project was to determine the strengths in poverty situations which should be capitalized on in developing educational programs…
