Sound Body,Sound Mind? The Interrelation Between Health Change and Personality Change in Old Age 
下载免费PDF全文
下载免费PDF全文 Personality development is characterized by increasing maturation, that is, people become more conscientious, agreeable and emotionally stable as they age. In late life, however, these trends seem to be reversed. Because many changes and transitions in older age are related to health, we investigated correlated changes in health problems and personality traits, the sources of health changes in later life and the directionality of effects. Our sample consisted of older adult twins, aged 64–85 years at time 1 (n = 410; 135 male/275 female; 134 monozygotic/63 dizygotic twin pairs), assessed at two different time points about five years apart, and we ran bivariate latent change and latent change twin model analyses. Increasing health problems were associated with decreases in agreeableness, extraversion, emotional stability and conscientiousness. Changes in health problems were only due to environmental influences, implying that the association between health and personality changes was exclusively environmental. Directional effects were largely absent, but health and personality were significantly related at the second measurement occasion (age 69–89 years). Our results support the link between health change and personality change in late life and spark the assumption of normative personality adaptations to deterioration of health status as a means of developmental regulation.

By adulthood, people judge trustworthiness from appearances rapidly and reliably. However, we know little about these judgments in children. This novel study investigates the developmental trajectory of explicit trust judgments from faces, and the contribution made by emotion cues across age groups. Five‐, 7‐, 10‐year‐olds, and adults rated the trustworthiness of trustworthy and untrustworthy faces with neutral expressions. The same participants also rated faces displaying overt happy and angry expressions, allowing us to investigate whether emotion cues modulate trustworthiness judgments similarly in children and adults. Results revealed that the ability to evaluate the trustworthiness of faces emerges in childhood, but may not be adult like until 10 years of age. Moreover, we show that emotion cues modulate trust judgments in young children, as well as adults. Anger cues diminished the appearance of trustworthiness for participants from 5 years of age and happy cues increased it, although this effect did not consistently emerge until later in childhood, that is, 10 years of age. These associations also extended to more subtle emotion cues present in neutral faces. Our results indicate that young children are sensitive to facial trustworthiness, and suggest that similar expression cues modulate these judgments in children and adults. 相似文献

The authors describe two pilot studies examining the potential benefits of Lunch Buddy (LB) mentoring, a manualized approach to school-based mentoring. LB mentoring takes place during the school lunch period and is designed to promote positive changes in children's peer relationships. In both studies, changes in peer victimization were assessed after one and three semesters of LB mentoring. In the first study, LB mentors were paired with elementary school children (N = 24) identified by child and teacher reports as victimized by peers. Results revealed significant declines in self- and teacher-rated victimization after one and three semesters of mentoring. In the second study, LB mentors were paired with victimized children who also engaged in bullying behavior (N = 23). Results indicated significant declines in self- and teacher-ratings of peer victimization after three semesters of mentoring. In both studies, ratings of perceived harm were low and ratings of satisfaction were high. Discussed are the implications of these findings for future research and for efforts to develop a nonharmful way to help children who are repeatedly victimized. 相似文献

Bystander intervention has been increasingly applied to prevent sexual violence on college campuses. Its underlying theory assumes unidirectional relationships between variables, predicting that bystander behaviors (i.e., actions taken to intervene in sexual violence situations) will be influenced by bystander intentions (BI; i.e., likelihood to intervene in the future), which in turn will be affected by bystander efficacy (BE; i.e., confidence to intervene). One question for theory is whether a reciprocal relationship exists between BI and BE. We used structural equation modeling (SEM) with longitudinal data to test unidirectional and reciprocal causal relations between BI and BE. Participants (n = 1390) were students at a northeastern US university. Four models were examined using SEM: (1) a baseline model with autoregressive paths; (2) a model with autoregressive effects and BI predicting future BE; (3) a model with autoregressive effects and BE predicting future BI; and, (4) a fully cross‐lagged model. Results indicated that reciprocal causality was found to occur between BI and BE. In addition, a final model demonstrated indirect effects of a bystander intervention program on bystander behaviors through both BI and BE at different time points. Implications for theory and practice are described, and directions for future research discussed. 相似文献

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed. 相似文献

Objectives: Within a trial of medical and surgical treatments for gastro-esophageal reflux disease (GORD), involving randomised arms and preference arms, we tested the applicability of the Beliefs about Medicines Questionnaire (BMQ) and developed and tested the validity of a new Beliefs about Surgery Questionnaire (BSQ). Methods: Patients with GORD (N = 43) were interviewed to elicit their beliefs about medical and surgical treatments. These contributed to the development of BSQ items. The BMQ and BSQ were completed by trial participants at baseline (randomised trial: N = 325; preference trial: N = 414). Factor analysis and discriminant function analysis were used to assess validity. Results: Principal components analysis (PCA) largely replicated the four-factor BMQ structure. PCA of the combined BMQ/BSQ yielded six factors explaining 54.5% variance. BSQ items loaded onto distinct factors, demonstrating divergence from BMQ. As predicted, BMQ/BSQ scores enabled correct classification of 78.5% of participants to medication and surgery groups in the preference trial (χ2(6) = 205.9, p < 0.001) but only 54.5% (no better than chance) in the randomised trial (χ2(6) = 9.4, p = 0.154). Conclusions: The BSQ is a valid measure of perceptions about surgical treatments for GORD. With the BMQ, it provides information that may guide patients’ choices about treatment. This measure may be applicable to other conditions. 相似文献

Individual differences are often incorporated into experimental research to elucidate inconsistent effects. We argue that the inclusion of such differences into established and seemingly straightforward findings is imperative to the goal of reaching a more complete understanding about the processes of interest. Drawing on research on the cognitive effects of positive affect, we illustrate how integrating individual differences in cognitive processing styles to this literature might lead to a more nuanced understanding of the impact of affect on cognitive processes. The addition of individual differences to psychological research should be seen as a means to a thorough scientific comprehension of a topic rather than as burdensome caveats to otherwise straightforward findings. 相似文献

Research into lying about intentions is relatively new. Studies have suggested that lying about intentions can be detected with statement analysing methods. This article describes two experiments. The first experiment investigates how much spatial and temporal detail is given by people who are discussing a true or false intention in a 26‐question interview. The results showed that those with a true intention gave more spatial and temporal details. The second experiment examines these details in a one‐question interview and whether the amount of temporal detail given can be manipulated by the phrasing of the question. The results showed that the amount of detail is much lower in these short interviews, but can be increased with specific phrasing. The theoretical and practical implications of these results are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The present study examined the antecedents of trust among operational Air Force fighter pilots for an automatic ground collision avoidance technology. This technology offered a platform with high face validity for studying trust in automation because it is an automatic system currently being used in operations by the Air Force. Pilots (N = 142) responded to an online survey which asked about their attitudes toward the technology and assessed a number of psychological factors. Consistent with prior research on trust in automation, a number of trust antecedents were identified which corresponded to human factors, learned trust factors, and situational factors. Implications for the introduction of novel automatic systems into the military are discussed. 相似文献
