Stability of intelligence from preschool to adolescence: the influence of social and family risk factors.
Multiple risk was important in longitudinal prediction, even after prior measurement of child IQ was accounted for; the pattern of risk was less important than the total amount of risk present in the child's context.
Sleep/wake patterns derived from activity monitoring and maternal report for healthy 1- to 5-year-old children.
Individual differences in sleep/wake measures reflect characteristics of children, parents, or parent-child interactions and investigate the impact of family demographic variables on sleep-wake measures.
Adolescent sleep patterns, circadian timing, and sleepiness at a transition to early school days.
Early start time was associated with significant sleep deprivation and daytime sleepiness, and the occurrence of REM sleep on MSLT indicates that clinicians should exercise caution in interpreting MSLT REM sleep in adolescents evaluated on their "usual" schedules.
Evidence for the validity of a sleep habits survey for adolescents.
The findings support the validity of the Sleep Habits Survey estimates in comparison with diary and actigraphy, andStrengths and limitations for survey measures of high school students' usual sleep/wake patterns are discussed.
Emotional Competence and Early School Adjustment: A Study of Preschoolers at Risk
This short-term longitudinal study examined whether emotion regulation and emotion understanding made unique contributions towards at-risk preschoolers' classroom adaptation. To address this
Estimating sleep patterns with activity monitoring in children and adolescents: how many nights are necessary for reliable measures?
Five or more nights of usable recordings are required to obtain reliable actigraph measures of sleep for children and adolescents and reliability estimates for values aggregated over any 5 nights were adequate for sleep start time, wake minutes, and sleep efficiency.
Effects of Acute Sleep Restriction on Behavior, Sustained Attention, and Response Inhibition in Children
Sleep restriction was associated with shorter daytime sleep latency, increased subjective sleepiness, and increased sleepy and inattentive behaviors but was not associated with increased hyperactive-impulsive behavior or impaired performance on tests of response inhibition and sustained attention.
Activity-based assessment of sleep-wake patterns during the 1st year of life
Abstract The aim of this study was to examine the validity of activity-based monitoring (actigraphy) for the assessment of sleep-wake patterns during the 1st year of life. Forty-one infants were
Showing and telling about emotions: Interrelations between facets of emotional competence and associations with classroom adjustment in Head Start preschoolers
In this study of low income preschoolers (N =  60), we examined relations between three facets of emotional competence: emotion knowledge, level of negative emotion expression, and emotion
Intelligence quotient scores of 4-year-old children: social-environmental risk factors.
Evidence is provided that no single factor identified here uniquely enhances or limits early intellectual achievement and that cumulative effects from multiple risk factors increase the probability that development will be compromised.
