Effortful control, the ability to suppress a dominant response over a subdominant one, is a fundamental aspect of self-regulation. It has been observed that higher levels of parenting stress are associated with lower levels of effortful control in children. Perceived social support, an important factor in reducing parenting stress, may act as a…

Prior research in non-U.S. samples has found a complex nonlinear relationship between loneliness and age. This research has shown that established predictors of loneliness--poor health, being unmarried, living alone, and having infrequent social interactions--help to explain age differences in loneliness. However, while some variables were found…

Background and Objective: Sixty countries worldwide have banned the use of physical punishment, yet little is known about the association of physical and nonphysical forms of child discipline with child development in a global context. The objective of this study is to examine whether physical punishment and nonphysical discipline are associated…

Background: Although plausible links between language development and personality have been suggested, longitudinal studies of these associations into adulthood have not been conducted. Aim: To investigate whether children's age at attaining language milestones is associated with later adult personality. Methods: Mothers' of 8,400 children from…

This study examined the associations among the socioeconomic status (SES) of Turkish families when children (N = 340, Mean age = 83 months, SD = 3.59, 50.3% boys) were approximately 7 years of age (Time 1) and their emotional lability and emotion regulation tendencies 3 years later (Time 3). We also examined the mediating roles of mothers' harsh…

The Convoy Model suggests that at different stages of the lifespan the makeup of the social support network varies in step with developmental and contextual needs. Cultural norms may shape the makeup of social convoys as well as denote socio-demographic differences in social support. This study examines the social convoys of adults in Mexico.…

Executive functions (EFs) may help children to regulate their food-intake in an "obesogenic" environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children's…

Premature infants have significant risk for later behavior problems. This study examined growth trajectories of three problem behaviors across five developmental age points from preschool to early adulthood in a well-characterized sample of premature infants. The effects of neonatal risk, gender, and socioeconomic context were modeled on these…

Research has previously shown a gap of near 0.5 of a standard deviation (SD) in cognition and language development between the top and bottom household wealth quartile in children aged 6-42 months in a large representative sample of low- and middle-income families in Bogota, using the Bayley Scales of Infant and Toddler Development. The gaps in…

This article documents differences in cognitive development, as measured by the Peabody Picture Vocabulary Test (PPVT), between children from households with high and low socioeconomic status (SES) in two different phases of early childhood in four developing countries. A large number of potential mediators, such as urban residence, preschool…

Using data from 1,676 youth who participated in three waves (Grades 6 to 8) of the longitudinal, 4-H Study of Positive Youth Development, we tested two series of hierarchal linear models to examine the role of peer support, associating with "problem-behaving" friends, and bullying involvement in the development of behavioral and emotional school…

The confounding of chronological and educational age and of schooling and socioeconomic status are persistent problems in the study of the cognitive consequences of schooling. The educational system among the Kharwar in India provides a natural experiment to overcome these problems, since it shows neither source of confounding. The sample…

This study explored social and experiential differences in children's (aged 4 to 14 years) concepts of inheritance. The study utilized semi-structured interviews including four tasks that were designed to elicit judgements and explanations about different aspects of inheritance understanding. A variety of social and experiential factors were…

Designed to determine whether (1) children of middle socioeconomic status (SES) learn matrix completion rules more rapidly than lower-SES children; (2) feedback influences rate of rule acquisition; (3) rule shifting influences rate of rule acquisition; (4) SES is associated with transfer of training; and (5) effectiveness of rule acquisition and…

Presents evidence from the Seattle Longitudinal Study to show that cognitive style and other lifestyle variables in middle life can predict part of the individual differences in ability decline in old age. High performance on fluid abilities and on motor-cognitive flexibility, an engaged lifestyle, and the absence of family dissolution at middle…
