The authors examined the relationship between body dissatisfaction and self-image across the life span. A sample of 106 women between the ages of 20 and 65 years completed questionnaire measures of body dissatisfaction, body importance, cognitive control over the body, self-concept, and self-esteem. The authors found that body dissatisfaction and body importance did not differ among the groups of women who were younger, middle aged, and older. Although body dissatisfaction was related to self-concept and self-esteem for the entire sample, the strength of that relationship reduced with increasing age and increasing perceptions of cognitive control. The authors concluded that the cognitive strategies of women who were older protect their self-concept and self-esteem from the influence of body dissatisfaction.  相似文献

The authors examined postural asymmetries during quiet stance and while holding evenly or unevenly distributed loads. Right-hand dominant subjects preferentially loaded their right lower limb when holding no load or a load evenly distributed in both hands, but no differences in center of pressure (CoP) were observed between the left and right limbs. However, longer CoP displacement was observed under the preferentially loaded limb, which may reflect a functional asymmetry that allows quick movement of one limb in response to a potential perturbation. When a load was held only in the nondominant hand, sample entropy decreased in the left (loaded) limb but increased in the right (unloaded) limb, suggesting the unloaded foot compensated for a loss of control flexibility in the loaded foot.  相似文献

The authors investigated the effects of an induced emotional mood state on lexical decision task (LDT) performance in 50 young adults and 25 older adults. Participants were randomly assigned to either happy or sad mood induction conditions. An emotional mood state was induced by having the participants listen to 8 min of classical music previously rated to induce happy or sad moods. Results replicated previous studies with young adults (i.e., sad-induced individuals responded faster to sad words and happy-induced individuals responded faster to happy words) and extended this pattern to older adults. Results are discussed with regard to information processing, aging, and emotion.  相似文献

Although individuals with depression have been found to experience a higher rate of stress in their lives, it remains unclear to what extent other personal characteristics may contribute to stress generation. The current study extended past research by examining the effects of two theoretically and empirically supported cognitive vulnerabilities to depression (negative cognitive style and rumination) as predictors of dependent interpersonal and achievement events, independent events, and relational peer victimization. In a diverse sample of 301 early adolescents (56 % female; Mage?=?12.82 years), we found that negative cognitive style prospectively predicted the experience of dependent interpersonal stress and relational victimization, and that rumination did not predict stress in any of the domains. Furthermore, the occurrence of intervening stress mediated the associations between negative cognitive style and subsequent depressive symptoms. Additionally, whereas negative cognitive style predicted relational victimization among both boys and girls, girls were particularly vulnerable to developing depressive symptoms following the occurrence of relational victimization. Thus, a negative cognitive style may contribute to the occurrence of stressful events, which in turn increases depressive symptoms. Girls may be particularly reactive to relational victimization, representing one pathway through which sex differences in depression may emerge.  相似文献

Research is needed on desistance from crime comparatively by gender. This research uses a national longitudinal sample of youth transitioning to adulthood. Drawing on Sampson and Laub's Age-Graded Theory of Informal Social Control, social bonds found in marriage and military involvement are examined to determine if they decrease delinquency over time. The results for the full sample revealed that marriage but not military involvement led to desistance. However, gender sub-sample analyses further showed military enlistment led females, but not males, to desist from crime. Implications and future research aims are discussed.  相似文献

Successive relearning combines two effective learning techniques (retrieval practice and spaced practice) and involves practicing retrieval until some level of mastery has been reached (i.e., at least one correct retrieval attempt) in each of multiple sessions. Several laboratory studies have demonstrated the promise of successive relearning for enhancing student learning, but attempts to evaluate its effectiveness in authentic educational contexts are limited. In the current research, we implemented successive relearning in a difficult biopsychology course to examine its effectiveness at enhancing student learning on a high-stakes exam. Students successively relearned some course content via a virtual flashcard program, whereas other course content was learned with business-as-usual activities. In two experiments, successive relearning boosted students' learning of course content by at least 10% (with ds ranging from 0.54 to 1.10). These findings suggest that implementing successive relearning in courses can be an effective method of promoting student achievement.  相似文献

This article aims to bridge the circadian and self‐control literatures by suggesting that people's self‐control performance varies as a function of their circadian preferences (i.e., chronotype). We review evidence for this assertion across a wide range of self‐control domains, including cognitive processing, emotion regulation, interpersonal relationships, and social influence. Across these widely ranging behaviors, the results indicate that when people's circadian preference matches the time of day, a synchrony effect occurs, and self‐control performance is at its peak. Therefore, people are more likely to display self‐regulatory failures and give in to temptations when there is a mismatch between their circadian preferences and time of day. Overall, this article offers new insights into the relationship between circadian preferences and self‐control and suggests novel and exciting new directions for future research.  相似文献

Social competence is a critical developmental milestone for preschoolers. Because play is the primary activity through which preschoolers interact socially with peers, it serves as an excellent indicator of social competence. The development of social competence in preschoolers is complex and multifaceted. In order to capture this complexity, we used Belsky’s differential susceptibility hypothesis as a framework for examining the contributions of child temperament and parenting styles in the prediction of peer interactive play behaviors. Using parent ratings of a sample of 44 preschool-age children, we hypothesized that child temperament (specifically, reactivity and regulation) acts as a susceptibility factor in the relationship between parenting styles (authoritarian and authoritative) and child peer play behaviors (disruptive and interactive). Our findings indicated that child reactivity moderated the relationship between authoritarian parenting style and both play outcomes, suggesting that reactivity serves as a potential susceptibility factor. More specifically, children with high reactivity who had more authoritarian parents demonstrated higher levels of disruptive play and lower levels of interactive play. Regulation did not act as a susceptibility factor in our sample. Findings are discussed in terms of implications for practice and in terms of an approach that considers temperament (specifically reactivity) and parenting behaviors in preschool assessment and intervention efforts. Additionally, we discuss how our findings partially support the differential susceptibility hypothesis.  相似文献

Erikson’s concept of generativity, or caring for the next generation, acknowledges the presence of narcissism or any type of self-preoccupation as potentially negative. However, other theories articulate generativity as including features of self-involvement, such as a drive for symbolic immortality (McAdams and de St. Aubin J Pers Soc Psychol 62(6):1003–1015. doi:10.1037/0022-3514.62.6.1003, 1992). Recent empirical research also supports this view by identifying generativity and narcissism as both incorporating the beneficial components of agency and communion (Frimer et al. J Pers Soc Psychol 101(1):149–163. doi:10.1037/a0023780, 2011; Gebauer et al. J Pers Soc Psychol 103(3):854–878. doi:10.1037/a0029629, 2012). Moreover, creating a legacy—something left behind when one dies—entails levels of both generativity and narcissism; thus, in the presence of generativity, narcissism may be seen as positive rather than negative. The current study examined generativity and narcissism, and their association with legacy, which was coded from midlife adults’ narratives concerning the future (age 55–58; N = 155). The findings indicated that a combination of high generativity and high narcissism was associated with the highest level of composite legacy, one in which both self and other are implicated. Results are discussed in light of the potentially positive outcomes of narcissism and its synergistic properties for legacy creation when combined with generativity.  相似文献
