Neuroticism is a predictor of many health problems. To study the determinants of within‐subject change in neuroticism, three hypotheses were tested: (i) subjects who experienced stressful life events (SLEs) show an increase in neuroticism; (ii) high baseline neuroticism moderated this effect; and (iii) recent SLEs had a greater impact on neuroticism than distant SLEs. Data came from the Finnish Twin Cohort. Neuroticism data were collected in 1975 and 1981 and SLEs data in 1981 (n = 21 085). By entering baseline neuroticism as a predictor for neuroticism at follow‐up, the outcome measure was change in neuroticism. Changes in neuroticism were predicted from SLE indices or their interaction with baseline neuroticism. Timing of SLEs was taken into account by distinguishing recent from distant SLEs. To control for confounding by shared genes and environments, both within‐twin pair and between‐twin pair effects were tested for monozygotic and dizygotic twin pairs separately. Neuroticism's six‐year stability was high (r = .58, p < .001). Exposure to SLEs modestly increased neuroticism (βs > .55, ps < .001), unconfounded by shared genes. This effect was not moderated by high baseline neuroticism. Recent SLEs (.09 < βs < .15) had more impact than distant SLEs (.03 < βs < .11; ps < .01). In conclusion, the findings strongly supported a model of environmentally driven SLEs causing dynamic fluctuations around a person's set point of neuroticism.

The purpose of this study was to examine whether anxious shyness and regulated shyness, initially identified in the Chinese culture, is found in South Korean children, and to explore whether these two forms of shyness were differentially related to children's psychosocial functioning. Participants were 544 fourth to sixth grade children (251 girls, M age = 11.38 years old) who were recruited from an elementary school in Bucheon City, South Korea. Children's anxious and regulated shyness were measured using peers' nominations and teachers' ratings, whereas their social preference and social impact were assessed using peers' nominations. Parents rated their children's temperamental shyness and effortful control, and children self‐reported their loneliness and interpersonal concerns. The results of confirmatory factor analysis replicated the two factor model of shyness found in previous studies of Chinese children. Anxious shyness and regulated shyness were positively associated and were similarly related to temperamental shyness. Anxious shyness was negatively related to effortful control and social preference, and positively associated with self‐reported loneliness and interpersonal concerns, whereas regulated shyness was positively related to effortful control and social preference and negatively associated with loneliness and social impact. These results were generally consistent with prior Chinese findings and provided preliminary support for the construct validity of anxious and regulated shyness in another Asian culture that emphasizes interdependence and modesty.

The present experiment investigated the behavioural patterns of interviewees when comparing their baseline behaviour, prior to the interview, with their behaviour during the investigative interview. Similar to what has been advised in the police literature, the truthful baseline behaviour was established prior to the interview through non‐threatening questions. The investigative part of the interview then followed in which the interviewee was aware that they would be assessed on whether they were lying. During the investigative part, interviewees either discussed the job that they had (truth tellers, n = 128) or pretended to have (liars, n = 115). Findings revealed that both liars and truth tellers' behavioural patterns differed between the baseline behaviour and the investigative part of the interview. The findings suggest small talk should not be used as a baseline comparison with the investigative part of the interview when determining if the interviewee is being deceitful. An alternative way of using a baseline lie detection method, the comparable truth method, is discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

This article deals with relationships and marriages of the Tlingit with immigrants from the Russian Empire as well as with representatives of other European and non-European peoples during the period when Alaska belonged to the Russian Empire. Matrimonial relations existed in two variants: legal, sanctified by the church, and in the form of permanent extramarital cohabitation or casual relationships. The latter variant absolutely predominated. With this, there was a sharply reflected gender imbalance, since men absolutely predominated among the immigrants, and therefore Tlingit women emerged in the role of marriage partners in the overwhelming majority of cases. A directly opposite pattern was observed in Tlingit contacts with the Athapaskans and to some extent with the Eyak. Matrimonial connections exerted influence on the workings of the Russian colonization, stimulated growth in mixed populations, and facilitated gradual acculturation of the Tlingit, along with contributing to the expansion of their ethnic territory. 相似文献

Family conflict is associated with longitudinal changes in insular‐striatal functional connectivity during adolescent risk taking under maternal influence 下载免费PDF全文
Maternal presence has marked effects on adolescent neurocognition during risk taking, influencing teenagers to make safer decisions. However, it is currently unknown whether maternal buffering changes over the course of adolescence itself, and whether its effects are robust to individual differences in family relationship quality. In the current longitudinal study, 23 adolescents completed a risk‐taking task under maternal presence during an fMRI scan before and after the transition to high school. Behavioral results reveal that adolescent risk taking increased under maternal presence across a one‐year period. At the neural level, we found that adolescents reporting higher family conflict showed longitudinal increases in functional coupling between the anterior insula (AI) and ventral striatum (VS) when making safe decisions in the presence of their mother, which was associated with increased real‐world risk taking. These findings show that individual differences in family relationship quality undermine effective development of AI‐VS connectivity resulting in increased risk taking. 相似文献

Mother still knows best: Maternal influence uniquely modulates adolescent reward sensitivity during risk taking 下载免费PDF全文
Adolescent decision‐making is highly sensitive to input from the social environment. In particular, adult and maternal presence influence adolescents to make safer decisions when encountered with risky scenarios. However, it is currently unknown whether maternal presence confers a greater advantage than mere adult presence in buffering adolescent risk taking. In the current study, 23 adolescents completed a risk‐taking task during an fMRI scan in the presence of their mother and an unknown adult. Results reveal that maternal presence elicits greater activation in reward‐related neural circuits when making safe decisions but decreased activation following risky choices. Moreover, adolescents evidenced a more immature neural phenotype when making risky choices in the presence of an adult compared to mother, as evidenced by positive functional coupling between the ventral striatum and medial prefrontal cortex. Our results underscore the importance of maternal stimuli in bolstering adolescent decision‐making in risky scenarios. 相似文献

The innovative moments model was used in a pilot study that aimed to explore the change processes involved in everyday change outside psychotherapy. According to this model, the emergence and development of innovative moments (IMs) as exceptions to a problematic pattern are closely associated with psychological change. A longitudinal design covering 4 months of interviews was implemented with 13 adults who were coping with significant personal problems without clinical psychopathological complaints. Semistructured interviews were used to explore participants' personal accounts of their problems, and change was assessed using a scaling task at the end of the study. A total of 114 interviews were analyzed using the innovative moments coding system. A general linear model showed that higher levels of change were associated with higher proportions of complex IMs over time. Moreover, lower levels of change were associated with an increase in elementary IMs. These results support the idea that successful psychological change in everyday life shares similarities with the change pattern found in psychotherapy using the innovative moments model. 相似文献

Many people aim to change their lifestyle, but have trouble acting on their intentions. Behavioral economic incentives and related emotions can support commitment to personal health goals, but the related emotions remain unexplored. In a regret lottery, winners who do not attain their health goals do not get their prize but receive feedback on what their forgone earnings would have been. This counterfactual feedback should provoke anticipated regret and increase commitment to health goals. We explored which emotions were actually expected upon missing out on a prize due to unsuccessful weight loss and which incentive-characteristics influence their likelihood and intensity. Participants reported their expected emotional response after missing out on a prize in one of 12 randomly presented incentive-scenarios, which varied in incentive type, incentive size and deadline distance. Participants primarily reported feeling disappointment, followed by regret. Regret was expected most when losing a lottery prize (vs. a fixed incentive) and intensified with prize size. Multiple features of the participant and the lottery incentive increase the occurrence and intensity of regret. As such, our findings can be helpful in designing behavioral economic incentives that leverage emotions to support health behavior change. 相似文献
