Phonological difficulties characterize children with developmental dyslexia across languages, but whether impaired auditory processing underlies these phonological difficulties is debated. Here the causal question is addressed by exploring whether individual differences in sensory processing predict the development of phonological awareness in 86…

Little research has considered whether prenatal experience contributes to executive function (EF) development above and beyond postnatal experience. This study tests direct, mediated, and moderated associations between prenatal risk factors and preschool EF and IQ in a longitudinal sample of 1,292 children from the Family Life Project. A composite…

Children adopted from institutions have been studied as models of the impact of stimulus deprivation on cognitive development (Nelson, Bos, Gunnar, & Sonuga-Barke, 2011), but these children may also suffer from micronutrient deficiencies (Fuglestad et al., 2008). The contributions of iron deficiency (ID) and duration of deprivation on…

This research examined how motivation (perceived control, intrinsic motivation, and extrinsic motivation), cognitive learning strategies (deep and surface strategies), and intelligence jointly predict long-term growth in students' mathematics achievement over 5 years. Using longitudinal data from six annual waves (Grades 5 through 10;…

Academic achievement and cognitive ability have been shown to predict later age at first sexual intercourse. Using a sample of 536 same-sex twin pairs who were followed longitudinally from adolescence to early adulthood, this study tested whether relations between intelligence, academic achievement, and age at first sex were due to unmeasured…

The development of 100 preterm infants from various social class and ethnic backgrounds was followed from birth to 5 years. Results indicated that developmental outcome at age 5 could be predicted moderately well from a single measure (infant visual attention) administered as early as term date. (Author/RH)

Examined risk factors of 3-year-old sons in 58 families with alcoholic fathers and 16 families with nonalcoholic fathers. Found that sons of alcoholic fathers were more impulsive than sons of nonalcoholic fathers. No differences between the groups in developmental age, IQ, or behavior problems were found. (MDM)

This review of literature on infant habituation and recognition memory performance as predictors of later IQ concludes that the level of prediction is (1) substantial; (2) higher for at-risk than nonrisk children; and (3) not higher than the level of predictions based on parental education and socioeconomic status. (MDM)

A total of 193 basically healthy working-class and middle-class mothers and their infants participated in a four-year longitudinal study. The study focused on the relative potency of several clusters of variables for predicting intellectual and language outcomes during the preschool years. (Author/RH)

Mothers provided personality assessments of 350 ethnically diverse 12- and 13-year-old boys using the California Child Q-set procedure to allow the development of scales to measure 5 personality dimensions: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. The resulting nomological network related these…

Studied the extent to which memory and processing speed accounted for relations between infant information processing and childhood IQ. Found that the relationship of 7-month visual recognition memory and 1-year cross-modal transfer to 11-year IQ were reduced when statistically controlled for factors derived from these measures, suggesting that…

Examined the relative role of parent-child relationships, family stress, and disease factors in predicting behavior problems in children with epilepsy. Found that children's self-reliance correlated with parent-reported behavior problems, whereas expression of affect related to teacher-reported problems. Overall, parent-child relationship factors…
