“…The lack of group differences to the emotional movie clip might stem from willingness or unwillingness of individuals from both groups to accurately report the thoughts and sensations they experience because of self-presentational concerns or cultural norms. Absence of expected significant overlap between self-reports to emotionally negative movie clips and EEG indicators of anxiety may also be due to unrelatedness of the BIS (which is overactivated in high anxiety) and the language system (where self-reports are generated) on a neurobiological level (Gray, 1988). Secondly, the findings from this study showed that high anxiety impact on laterality and emotion is manifested in the theta and beta-1 frequency bands.…”

“…State anxiety is the transitory pattern of emotions elicited by environmental stressors, including physiological arousal and symptoms of apprehension, worry, and tension (Spielberger, 1966). It has been associated with systems involved in the detection and vigilance for threat in the external world (Gray, 1988), and as such is thought to represent the environmentally reactive component of anxiety. In contrast, trait anxiety refers to individual differences in the predisposition to respond to threatening situations (Spielberger, 1966), and is often characterised as a personality disposition.…”

State and trait anxiety define different aspects of anxiety, and may represent environmentally and genetically mediated components of this phenotype. Furthermore their relationship, where trait anxiety is expressed through levels of state anxiety under threatening circumstances, may represent a process of interplay between a genetic vulnerability factor and an environmental stressor. To test these hypotheses, we explored genetic and environmental influences on measures of state and trait anxiety in a sample of 1058 twins (521 males and 537 females) aged 8-16. The results were consistent with these hypotheses. State anxiety is largely influenced by environmental factors in males and females whereas trait anxiety shows moderate genetic effects and substantial non-shared environment effects. Their association was accounted for by non-shared environmental effects, with modest genetic and shared environmental inputs. The implications of these results for vulnerability mechanisms involving stress reactivity on anxiety are discussed.
