Background and objectives: The negative effects of the financial crisis of 2007/2008 are still being felt today as seen in the relatively high levels of youth unemployment in many countries. As a result, many young people experience high stress levels when facing an uncertain and precarious job market.

Methods: Participants were 178 undergraduate students (79% female; Mage?=?20.00, SD?=?4.29) who were randomly assigned to read a news article that documented an uncertain financial future with limited job opportunities (the economic stress group), or an article that documented a tour of the Royal Canadian Mint (the control group). The role of self-compassion was explored in its relation to distress.

Results: Correlational and hierarchical regression analyses indicated that, in the economic stress group, self-compassion negatively predicted anxiety above and beyond self-esteem and familial support. In the control group, however, self-compassion did not negatively predict anxiety above and beyond self-esteem and familial support. Additionally, structural equation modeling indicated that self-compassion was directly associated with lower anxiety and indirectly related to anxiety through perceptions of financial threat.

Conclusions: These findings suggest that self-compassion may be an important resource that is associated with less distress during times of economic threat.  相似文献

The State-Trait Anxiety Inventory for Children is a self-report instrument inspired on the State-Trait theory extended by Spielberger that measures a momentary state of anxiety (state) and a stable tendency to experience anxiety (trait). This study presents an exploratory adaptation of the Trait Scale and provides its psychometric properties for European Portuguese children and adolescents. The influence of sex and age were also explored. Our sample, composed of 402 participants aged 8–14 years, revealed a mean anxiety value of 28.37 (SD = 5.99). As expected, females revealed higher levels of anxiety than boys. Higher anxiety was obtained in our youngest group as compared to the oldest group. The exploratory factor analysis led to retaining only 16-items that presented acceptable adjustment to a one-factorial solution. Good indexes were obtained in the confirmatory analysis. The results also revealed good internal consistency and good test-retest reliability. Our results provide initial evidence that this scale is adequate to measure trait-anxiety in European Portuguese young people.  相似文献

The adenosine A(2A) receptor (A(2A)R) is highly enriched in the striatum where it is uniquely positioned to integrate dopaminergic, glutamatergic, and other signals to modulate cognition. Although previous studies support the hypothesis that A(2A)R inactivation can be pro-cognitive, analyses of A(2A)R's effects on cognitive functions have been restricted to a small subset of cognitive domains. Furthermore, the relative contribution of A(2A)Rs in distinct brain regions remains largely unknown. Here, we studied the regulation of multiple memory processes by brain region-specific populations of A(2A)Rs. Specifically, we evaluated the cognitive impacts of conditional A(2A)R deletion restricted to either the entire forebrain (i.e., cerebral cortex, hippocampus, and striatum, fb-A(2A)R KO) or to striatum alone (st-A(2A)R KO) in recognition memory, working memory, reference memory, and reversal learning. This comprehensive, comparative analysis showed for the first time that depletion of A(2A)R-dependent signaling in either the entire forebrain or striatum alone is associated with two specific phenotypes indicative of cognitive flexibility-enhanced working memory and enhanced reversal learning. These selective pro-cognitive phenotypes seemed largely attributed to inactivation of striatal A(2A)Rs as they were captured by A(2A)R deletion restricted to striatal neurons. Neither spatial reference memory acquisition nor spatial recognition memory were grossly affected, and no evidence for compensatory changes in striatal or cortical D(1), D(2), or A(1) receptor expression was found. This study provides the first direct demonstration that targeting striatal A(2A)Rs may be an effective, novel strategy to facilitate cognitive flexibility under normal and pathologic conditions.  相似文献

The relationship context of human behavior and development   总被引:12,自引:0,他引:12  
The influence of social relationships on human development and behavior is receiving increased attention from psychologists, who are central contributors to the rapidly developing multidisciplinary field of relationship science. In this article, the authors selectively review some of the significant strides that have been made toward understanding the effects of relationships on development and behavior and the processes by which relationships exert their influence on these, with the purpose of highlighting important questions that remain to be answered, controversial issues that need to be resolved, and potentially profitable paths for future inquiry. The authors' thesis is that important advances in psychological knowledge will be achieved from concerted investigation of the relationship context in which most important human behaviors are developed and displayed.  相似文献

It has been well documented that people with negative emotional reactions to sex (e.g., "erotophobia,""sex guilt") have less knowledge about contraception than do people with more positive reactions. Recent research has suggested that this deficit is not related to an inability to learn the information, but is due at least in part to the fact that erotophobics actively avoid contraceptive information. The current study was designed to examine the role of erotophobia and high self-esteem in resistance to learning sexual information. More specifically it compared pretest and posttest knowledge of contraception and AIDS in high self-esteem and low self-esteem, erotophobia, and erotophilic women in a university class on human reproduction. As expected, high self-esteem erotophobic subjects were less Likely than other subjects to retain contraceptive and AIDS information presented in the class. Implications of this study for contraceptive and AIDS educational strategies are discussed.  相似文献

A convenience sample of 99 Black and 63 White adolescent mothers participated in a study of child-rearing beliefs and behaviors. Attitudes toward child-rearing were assessed using a scale developed for low-income, Black adolescent mothers. The HOME was used by trained observers to record parenting behavior. The Black and White samples were comparable in terms of income, employment status, educa tion, and age. Black mothers were more likely than White mothers to advocate some authoritarian child-rearing techniques. Black and White mothers with desirable attitudes toward parenting and positive parenting behaviors exceeded the number expected on the basis of chance alone. Overall, Black mothers were not as punitively oriented in either words or deeds as depicted in sociological analyses. The results of this analysis point to the importance of recognizing diversity in parental attitudes and behavior both between and within racial groups in the broader context of the changing role of adolescent mothers in our society.  相似文献

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.  相似文献

The authors explored the contribution of individual differences in attachment orientations to the experience of sexual intercourse and its association with relationship quality. In Study 1, 500 participants completed self-report scales of attachment orientations and sexual experience. The findings indicated that whereas attachment anxiety was associated with an ambivalent construal of sexual experience, attachment avoidance was associated with more aversive sexual feelings and cognitions. In Study 2, 41 couples reported on their attachment orientations and provided daily diary measures of sexual experiences and relationship interactions for a period of 42 days. Results showed that attachment anxiety amplified the effects of positive and negative sexual experiences on relationship interactions. In contrast, attachment avoidance inhibited the positive relational effect of having sex and the detrimental relational effects of negative sexual interactions. The authors discuss the possibility that attachment orientations are associated with different sex-related strategies and goals within romantic relationships.  相似文献

In human communication and mate selection the appearance of health sends signals regarding biological fitness. We compared the appearance of health in the sides of the face to previous results on left-right facial asymmetry in the appearance of beauty (1). The stimuli were created by aligning the left and right sides of the face each with its own mirror image. Here, participants viewed 38 pairs of left-left and right-right faces and judged which member of the pair looked healthier. No significant interaction emerged between decision (health vs attractiveness) and face side. Rather, in women's faces right-right was significantly more healthy and attractive than left-left, while in men's faces there was no significant left-right difference. In biology and evolution, health and beauty are closely linked and the findings here confirm this relationship in human faces.  相似文献
