摘要: The purpose of the current study was to investigate potential genetic and environmental correlations between working memory three behavioral aspects attention network (i.e., executive, alerting, orienting) using a twin design. Data were from 90 monozygotic (39% male) 112 same-sex dizygotic (41% twins. Individual differences in performance (digit span) parent-rated measures orienting included modest moderate variance, shared nonshared variance. As hypothesized, correlated with executive alerting attention, but not attention. correlation memory, completely accounted for by overlapping covariance, suggesting common mechanism or mechanisms underlying links certain indicators attentive behavior.
