Theory and data generally concur that a slower Life History Strategy (LHS) is associated with higher Conscientiousness, Agreeableness and Emotional Stability. Whether Extraversion and Openness are indicators of a slow LH, or whether they include both fast and slow LH components, remains unresolved. I addressed these questions in two studies: one of university students observed via periodic brief audio recordings during 72 h of their daily lives, and the second a re-analysis of data from Block and Block's (2006) longitudinal study. In both studies, I operationalized LHS as the correlation between an individual's California Q-Sort (CAQ) profile and the slow Life History (SLH) CAQ template created by Sherman et al. (2013) and Dunkel et al. (2015). I calculated Five Factor Model dimension scores using McCrae et al's (1986) method. In both samples, individuals whose CAQ profile more closely resembled the SLH template were higher in Conscientiousness, Agreeableness, and Emotional Stability than those pursuing a faster LHS. Extraversion was unrelated to LHS, while Openness in the Block and Block data set was actually associated with a faster LHS. Analysis of individual CAQ items revealed some differences between the studies. Generally, Extraversion-loading items tapping excitement-seeking and self-dramatization, and Openness-loading items tapping nonconformity, were associated with a faster LHS. Participants in the audio recording study also completed a HEXACO personality inventory and the Arizona Life History Battery. LHS as measured by the ALHB was uncorrelated with LHS as measured by the CAQ. Controlling for Extraversion yielded a significant positive relationship between the two LHS measures, suggesting that their poor convergent validity resulted from differences in their coverage of Extraversion-related content.  相似文献

A mail-in questionnaire study and two confirmatory archival analyses are described. Variables related to personality and measures of sleep timing, sleep quality, and sleep duration were initially assessed by self-report in a sample of 54 working adults (31.5% male, 23-48 yrs). Extraversion and neuroticism were measured by the Eysenck Personality Inventory (EPI), and the level of sub-clinical manic-type symptoms by the Attitude to Life Questionnaire (ATLQ). The quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI) and by questions relating to habitual sleep latency and minutes awake after sleep onset from the Sleep Timing Questionnaire (STQ). The duration and timing of sleep was assessed using the STQ separately for work-week nights (Sunday-Thursday) and for weekend nights (Friday and Saturday). Morningness-eveningness was assessed using the Composite Scale of Morningness (CSM). Two confirmatory analyses using separate archival samples (Study A: n=201, 55.7% male, 20-57 yrs; Study B: n=101, 47.5% male, 18-59 yrs) were then used to confirm specific correlations of interest. In both initial and confirmatory studies, increased sub-clinical manic-type symptoms were found to be significantly associated with later bedtimes and wake-times during the work-week and lower (more evening-type) CSM scores, and higher neuroticism was associated with poorer sleep as indicated by higher PSQI scores. In contrast, no significant correlations emerged between any of the personality variables and any of the sleep duration variables. Personality appears to affect certain aspects of the timing and subjective quality of sleep, but not necessarily its duration.  相似文献

IntroductionThe relationship between extraversion and wellbeing has been discussed in the literature, however, the impact that this trait has on the wellbeing of older people has been studied to a lesser extent. The relationship between extraversion, participation in activities and psychological wellbeing in older people is analysed in this study.Material and methodsThe sample comprised 139 individuals over 55 years from rural and urban areas of the province of Granada who completed the extraversion subscale of the NEO-FFI and the Ryff Scales of the Psychological Wellbeing, as well as responding to questions that evaluated their social participation.ResultsA greater social participation was found in rural areas and among women. The activities more frequently performed by the participants were educational and religious activities, walking, everyday chores, crafts, and home improvements. A low positive correlation between extraversion and wellbeing was observed. The multiple regression analysis revealed that extraversion explained 19.9% of the variance in psychological wellbeing, which increased to 25.3% when social participation, gender, and the origin of the sample were considered.ConclusionsPsychological wellbeing appears to be associated with personality traits, such as extraversion. In addition this personality trait is linked to the number and type of activities the elderly perform which also contributes to wellbeing in old age.  相似文献

Atypical fatty acid metabolism has been reported in attention deficit hyperactivity disorder (ADHD), however, its relationship with temperament in this population is unclear. The current study investigated the association between blood levels of fatty acids implicated in brain structure and function (omega-3, omega-6, omega-9) and personality traits of stability (neuroticism, conscientiousness and agreeableness) and plasticity (extraversion and openness). Twenty right-handed adolescent boys with ADHD completed a self-report NEO-FFI personality questionnaire, and had fatty acid content assessed from red blood using gas chromatography. Pearson's correlations showed no significant associations between omega-3 levels and personality. After correction for multiple comparisons, Adrenic Acid (C22:4n6) was inversely associated with stability. Oleic acid (C18:1n9) was positively associated with plasticity. Results are in line with a role of fatty acids in brain function. They suggest that those fatty acids that are involved in myelination (Adrenic, Oleic) have the strongest associations with temperament in adolescents with ADHD.  相似文献
