Dobrova-Krol, Natasha A.; van IJzendoorn, Marinus H.; Bakermans-Kranenburg, Marian J.; Juffer, Femmie – Child Development, 2010
To study the effects of perinatal HIV-1 infection and early institutional rearing on the physical and cognitive development of children, 64 Ukrainian uninfected and HIV-infected institutionalized and family-reared children were examined (mean age = 50.9 months). Both HIV infection and institutional care were related to delays in physical and…

The Development of Regulatory Functions from Birth to 5 Years: Insights from Premature Infants
Peer reviewed Peer reviewed
Direct linkDirect link
Feldman, Ruth – Child Development, 2009
This study examined physiological, emotional, and attentional regulatory functions as predictors of self-regulation in 125 infants followed 7 times from birth to 5 years. Physiological regulation was assessed by neonatal vagal tone and sleep-wake cyclicity; emotion regulation by response to stress at 3, 6, and 12 months; and attention regulation…

Physical Activity Play: Consensus and Debate.
Peer reviewed Peer reviewed
Pelligrini, A. D.; Smith, Peter K. – Child Development, 1998
Considers areas of consensus from commentaries, including the value of an evolutionary perspective and the utility of exploring variations in physical activity play. Examines areas of debate, including the nonplay-play distinction, functions of rough-and-tumble play, and the opportunities of juveniles for exercise training. Calls for more directed…

Learning To Crawl.
Peer reviewed Peer reviewed
Adolph, Karen E.; Vereijken, Beatrix; Denny, Mark A. – Child Development, 1998
Examined longitudinally the effects of infants' age, body dimensions, and experience on the development of crawling. Although most infants displayed multiple crawling postures en route to walking, development did not adhere to a strict progression of obligatory, discrete stages. Duration of experience with earlier forms of crawling predicted the…

Distinguishes three kinds of physical activity play with consecutive age peaks: rhythmic stereotypies, exercise play, and rough-and-tumble play. Considers gender differences and function in terms of immediate and deferred consequences in physical, cognitive, and social…

The Biology of Human Play.
Peer reviewed Peer reviewed
Byers, John A. – Child Development, 1998
Maintains that the "getting into shape" hypothesis of explaining the inverted-U distribution of exercise play across age is likely incorrect. Argues that the biological study of human physical activity play, as recommended by Pellegrini and Smith (1998), will reveal whether physical activity play represents an example of…
