Socioeconomic status and the growth of intelligence from infancy through adolescence

Abstract: Low socioeconomic status (SES) children perform on average worse on intelligence tests than children from higher SES backgrounds, but the developmental relationship between intelligence and SES has not been adequately investigated. Here, we use latent growth curve (LGC) models to assess associations between SES and individual differences in the intelligence starting point (intercept) and in the rate and direction of change in scores (slope and quadratic term) from infancy through adolescence in 14,853 children… Show more

“…Intercorrelations between the aggregated cognitive scores in the present study were moderate to strong, with the exception of scores within the first year, which were modestly but positively associated with cognitive ability in childhood and adolescence. Moreover, correlations between cognitive scores over time in the present study were stronger than those observed in previous longitudinal studies of cognitive development (Honzik et al, 1948; von Stumm & Plomin, 2015). Thus, there appears to be some meaningful overlap in the abilities assessed at each age.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…In our sample, we observed that twins score more than 6 points lower on the ABIQ6 than singletons. These findings are consistent with previous reports (Ronalds et al, 2005), but often go undiscussed in heritability studies of cognition (Bishop et al, 2003; Stumm & Plomin, 2015). Importantly, we found that the predictive ability of scores at ages 1 and 2 for subsequent school-age IQ were notably higher for twins compared to singletons, with the ELC1 being nearly three times as predictive in twins.…”

“…Our results are in line with a number of studies suggesting that early-life stressors associated with lack of socioeconomic resources negatively influence cognitive functions ( Hart et al. , 2007 ; Von Stumm and Plomin, 2015 ; Alves et al. , 2016 ; Cermakova et al.…”
