This study investigated the role of fluid intelligence, personality traits and perceived cognitive failure in relation to indecisiveness. The Advanced Progressive Matrices (APM), the Big Five Questionnaire (BFQ) and the Cognitive Failures Questionnaire (CFQ) were administered to 429 Italian high school students. The study revealed that perceived cognitive failure added a significant percentage of incremental variance in indecisiveness compared to variances due to fluid intelligence and personality traits thereby offering new research and intervention possibilities. 相似文献

A genetic variant (COMT) coding dopaminergic activity predicts personality traits in healthy elderly
Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range for detecting a relationship. The present study examined associations of COMT rs4680 and personality in older adults.Genetic association analyses were carried out between the NEO and the targeted COMT rs4680 in a large, well-characterized sample of healthy, cognitively normal older adults (N = 616, mean age = 69.26 years).Three significant associations were found: participants with GG genotype showed lower mean scores on Neuroticism (p = 0.039) and higher scores on Agreeableness (p = 0.020) and Conscientiousness (p = 0.006) than participants with AA or AG genotypes.These results suggest that older adults with higher COMT enzymatic activity (GG), therefore lower dopamine level, have lower Neuroticism scores, and higher Agreeableness and Conscientiousness scores. This is consistent with a recent model of phasic and tonic dopamine release suggesting that even though GG genotype is associated with lower tonic dopamine release, the phasic release of dopamine might be optimal for a more adaptive personality profile. 相似文献
