Slower and more variable performance in speeded reaction time tasks is a prominent cognitive signature among children with Attention Deficit Hyperactivity Disorder (ADHD), and is often also negatively associated with executive functioning a...
Genetic and environmental contributions to IQ in adoptive and biological families with 30-year-old offspring [0.03%]

While adoption studies have provided key insights into the influence of the familial environment on IQ scores of adolescents and children, few have followed adopted offspring long past the time spent living in the family home. To improve co...

In two large-scale longitudinal datasets (combined N = 5761), we investigated ability-related political polarization in responses to the COVID-19 pandemic. We observed more polarization with greater ability in emotional responses, risk perc...

Although prior theory suggests that rumination contributes to cognitive impairments associated with depression, recent work suggests that rumination is associated with higher levels of intelligence. The present study examined the relations ...
The causal influence of brain size on human intelligence: Evidence from within-family phenotypic associations and GWAS modeling [0.03%]
大脑尺寸对人类智力的因果影响：来自家庭内表型联系和全基因组关联研究建模的证据

There exists a moderate correlation between MRI-measured brain size and the general factor of IQ performance (g), but the question of whether the association reflects a theoretically important causal relationship or spurious confounding rem...

This study documents differences in childhood IQ trajectories of Guatemala City children, aged 6-15 years and born 1961-1993, according to school attended, height-for-age Z-scores (HAZ) and over time (Flynn effect). IQ data come from the Un...
The Flynn effect for fluid IQ may not generalize to all ages or ability levels: a population-based study of 10,000 US adolescents [0.03%]
流体智力的弗林效应可能不适用于所有年龄段或能力水平：一项针对10000名美国青少年的研究
Jonathan M Platt,Katherine M Keyes,Katie A McLaughlin et al.
Jonathan M Platt et al.
Generational changes in IQ (the Flynn Effect) have been extensively researched and debated. Within the US, gains of 3 points per decade have been accepted as consistent across age and ability level, suggesting that tests with outdated norms...
Fluctuating asymmetry in brain structure and general intelligence in 73-year-olds [0.03%]
大脑结构的对称性波动和73岁人群的智力水平关系研究

Joanna E Moodie et al.
Fluctuating body asymmetry is theorized to indicate developmental instability, and to have small positive associations with low socioeconomic status (SES). Previous studies have reported small negative associations between fluctuating body ...
Structural brain imaging correlates of general intelligence in UK Biobank [0.03%]
英国生物样本库中一般智力的脑结构影像学标志物
S R Cox,S J Ritchie,C Fawns-Ritchie et al.
S R Cox et al.
The associations between indices of brain structure and measured intelligence are unclear. This is partly because the evidence to-date comes from mostly small and heterogeneous studies. Here, we report brain structure-intelligence associati...
Socioeconomic status amplifies genetic effects in middle childhood in a large German twin sample [0.03%]

The Scarr-Rowe hypothesis predicts that the heritability of cognitive abilities is higher in more privileged socioeconomic conditions, meaning that genetic potential can be more fully expressed in environments characterized by high socioeco...
