Older individuals who recognize their cognitive difficulties are more likely to adjust their everyday life to their actual cognitive functioning, particularly when they are able to estimate their abilities accurately. We assessed self- and spouse-ratings of memory and attention difficulties in everyday life of healthy, older individuals and compared them with the respective test performance. Eighty-four older individuals (women's age, M = 67.4 years, SD = 5.2; men's age, M = 68.5 years, SD = 4.9) completed both the self and the spouse versions of the Attention Deficit Questionnaire and the Everyday Memory Questionnaire and completed two neuropsychological tests. Using the residual score approach, subjective metacognitive measures of memory and attention were created and compared with actual test performance. Significant associations between subjective and objective scores were found only for men and only for episodic memory measures. Men who underreported memory difficulties performed more poorly; men who overreported memory difficulties performed better. Men's recognition performance was best predicted by subjective measures (R2 = .25), followed by delayed recall (R2 = .14) and forgetting rate (R2 = .13). The results indicate gender-specific differences in metacognitive accuracy and predictive validity of subjective ratings.  相似文献

The impact of fingers on numerical and mathematical cognition has received a great deal of attention recently. However, the precise role that fingers play in numerical cognition is unknown. The current study explores the relationship between finger sense, arithmetic and general cognitive ability. Seventy-six children between the ages of 5 and 12 participated in the study. The results of stepwise multiple regression analyses demonstrated that while general cognitive ability including language processing was a predictor of addition performance, finger sense was not. The impact of age on the relationship between finger sense, and addition was further examined. The participants were separated into two groups based on age. The results showed that finger gnosia score impacted addition performance in the older group but not the younger group. These results appear to support the hypothesis that fingers provide a scaffold for calculation and that if that scaffold is not properly built, it has continued differential consequences to mathematical cognition.  相似文献

There is growing interest in the use of consumer level exergames in movement skill acquisition. The purpose of this study was to investigate the relationship between movement proficiency and performance in virtual exergaming. Twenty seven children, aged 10–15 years participated in an experiment completing the Movement Assessment Battery for Children 2 (MABC-2) and a series of XBOX360 Kinect Sports exergaming tasks. Significant correlations were observed between MABC-2 aiming and catching percentile and exergame javelin and target kick, where the more proficient movers tended to perform better in the exergame. Statistically significant correlations were observed between MABC-2 balance percentile and exergaming sprint and target kick performance. In this study children who scored better in real life gross motor movement tasks performed better in most related exergaming activities. This suggests current exergaming technology has advanced to a point where body movement unencumbered by a physical or remote game device tether can extract movements resembling real life tasks, translate them into game play and reward proficient movers with higher in-game performance. It is possible that benefit gained in an exergaming environment by more proficient movers was a result of either their more proficient movement, or a greater ability to adapt to the exergame.  相似文献

Studies investigating body image satisfaction among groups of different sexual orientations (i.e., gay men, lesbian women, and heterosexual men and women) have produced equivocal findings. To synthesise the available research, 27 studies (20 published and 7 unpublished) were meta-analysed (N=5220). Comparisons between heterosexual (n=1397) and gay men (n=984) produced a small effect size, with the former being slightly more satisfied with their bodies. An even smaller difference was observed for studies comparing heterosexual (n=1391) and lesbian women (n=1448), with greater levels of body satisfaction being evidenced by the latter group. Tests of homogeneity for each effect size were found to be highly significant. In an attempt to identify variables that may be responsible for the observed heterogeneity, the following categorical factors were assessed: the measures used to evaluate body satisfaction, date of study (1980s versus 1990s+), publication status (published or unpublished), and body weight. The results of this exploratory search for potential moderator variables as well as limitations of the current meta-analysis are discussed.  相似文献

The paper examines the effect of strategic training on the performance of younger and older adults in an immediate list-recall and a working memory task. The experimental groups of younger and older adults received three sessions of memory training, teaching the use of mental images to improve the memorization of word lists. In contrast, the control groups were not instructed to use any particular strategy, but they were requested to carry out the memory exercises. The results showed that strategic training improved performance of both the younger and older experimental groups in the immediate list recall and in the working memory task. Of particular interest, the improvement in working memory performance of the older experimental group was comparable to that of the younger experimental group.  相似文献

In two separate experiments, three groups of older adults (50-80 years old) were shown lists of forename-surname pairs. At test subjects were cued with the surname and asked whether they knew the forename (prospective evaluation). Subjects attempted recall for those items they claimed to know and rated their confidence in their answer (retrospective evaluation). In Experiment 1 subjects saw the name list on 5 successive occasions and attempted recall after each. The older subjects recalled fewer items, but there were no age differences on retrospective memory evaluation. There was a marginally significant age effect on the prospective memory evaluation, which on closer inspection appeared to be a scaling effect related to recall performance. Experiment 2 verified this conclusion in a sample of older adults taking part in a training study extended over many weeks. The main implication of this work is that studies that compare metamemory accuracy in groups that differ in baseline memory performance should be careful before drawing conclusions about metamemory independently of memory performance.  相似文献

The present study provided an initial evaluation of an affect regulation model describing the association between body dissatisfaction and two contemporary measures of positive body image among 247 Black college-bound older adolescent females. We further tested whether possessing a higher body mass index (BMI) would strengthen these associations. Self-reported height and weight were used to calculate BMI. Respondents also completed a culturally-sensitive figure rating scale along with assessments of body appreciation and body image flexibility. Results indicated a robust positive association between the two measures of positive body image; BMI was the strongest predictor of both body appreciation and body image flexibility with body size discrepancy (current minus ideal) contributing incremental variance to both models tested. Implications for improving our understanding of the association between positive and negative body image and bolstering positive body image to promote health-protective behaviors among Black young women at this developmental juncture are discussed.  相似文献

Appearance contingent self-worth has been shown to be associated with low appearance self-esteem but little is known about the role that objectified body consciousness may play in this relationship. The purpose of the present study with 465 female undergraduates was to examine whether objectified body consciousness mediates the association between appearance contingent self-worth and low levels of appearance self-esteem. This was accomplished using a multiple mediation model to examine whether components of objectified body consciousness (i.e., body surveillance, body shame, and control beliefs) play unique roles in the connection between appearance contingent self-worth and appearance self-esteem. Results showed that body surveillance and body shame were significant mediators of the connection between appearance contingent self-worth and low levels of appearance self-esteem. Discussion focuses on the implications of these results for the ways in which appearance contingent self-worth may promote heightened body consciousness and possibly contribute to low levels of appearance self-esteem.  相似文献

Interview anxiety is negatively related to interview performance; however, its relation to job performance is unknown. It could correlate negatively with job performance, and it could moderate the interview performance–job performance relation. In a sample of applicants for Residence Assistant positions, interview anxiety had near‐zero correlations with job performance, rated by supervisors and supervisees. It moderated the relation between interview performance and supervisor‐rated facilitating peer and team performance, such that interview performance did not predict this job performance component for anxious applicants. The moderation was not found for supervisor‐rated task proficiency, or for supervisee ratings of either job performance component, suggesting that the impact of interview anxiety depends on rater source and which job performance component is rated.  相似文献

Abstract

The main objective of this study is to test the effects over time of three role stress variables (role conflict, role ambiguity and role overload) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment). Based on theoretical models on burnout and on meta-analytical research, it is hypothesized that the three role stress variables will predict changes over time in emotional exhaustion and depersonalization, but not in personal accomplishment. The results obtained by means of hierarchical regression analysis partially support the hypothesis. The three role stress variables predict emotional exhaustion over time. Role conflict and role overload predict depersonalization over time. Finally, contrary to expectations, role ambiguity predicts personal accomplishment over time.  相似文献

Motivational interviewing is a directive, non-confrontational intervention to promote behavior change. The current study examined therapist behaviors during a successful brief motivational interviewing intervention for physically aggressive college dating couples (Woodin & O'Leary, 2010). Forty-five minute motivational interviews with each partner were videotaped and coded using the Motivational Interviewing Treatment Integrity scale (MITI; Moyers, Martin, Manuel, & Miller, 2003). Hierarchical modeling analyses demonstrated that therapist behaviors consistent with motivational interviewing competency predicted significantly greater reductions in physical aggression perpetration following the intervention. Specifically, greater reflection to question ratios by the therapists predicted reductions in aggression for both men and women, greater percentages of open versus closed questions predicted aggression reductions for women, and there was a trend for greater levels of global therapist empathy to predict aggression reductions for women. These findings provide evidence that motivational interviewing seems to have an effect on behavior change through therapist behaviors consistent with the theoretical underpinnings of motivational interviewing.  相似文献

Prior research has suggested that episodes of mind wandering not only negatively impact text comprehension but also are associated with fluctuations in reading behavior. However, these studies typically do not account for differences in the fundamental nature of the text itself, namely, whether it is narrative or expository in structure. As much research has supported the idea that these text genres are processed differently, it is of interest to determine whether similar changes in reading patterns are observed when mind wandering in an expository text. The present study examined whether fluctuations in sentence‐by‐sentence reading times were associated with periods of mindless reading during processing of an expository text. Results indicated that although mindless reading did negatively impact learning, probed reading time did not vary as a function of mind wandering. These results suggest that research aimed at studying mind wandering while reading may need to account for text genre.  相似文献

The present study aimed to investigate whether different spatial abilities and strategies sustain perspective-taking (PT) performance in males and females. The PT task used was the Object Perspective Test (OPT, Kozhevnikov and Hegarty in Mem Cogn 29:745-756, 2001; Hegarty and Waller in Intelligence 32:175-191, 2004). A sample of 40 males and 40 females completed the OPT and several other visuo-spatial tasks and questionnaires. Multiple regression analysis showed that OPT performance was predicted positively by a spatial imagery preference and negatively by the specific use of mental rotation strategy (i.e. turning the sheet of paper). Gender interacted with the Embedded Figure Test (EFT), a spatial visualization task, since high EFT scores only positively predicted the OPT results in males. Overall, our results show that OPT performance is sustained by specific spatial abilities and strategies modulated, at least in part, by gender.  相似文献

Does empathy predict adolescents' bullying and defending behavior?   总被引:1,自引:0,他引:1  
Through structural equation modeling, this study tested a path of relations in which different levels of empathic responsiveness were posited to be differently associated to bullying and defending behavior. Three hundred and eighteen Italian adolescents (142 girls and 176 boys; mean age = 13.2 years) completed the Davis's Interpersonal Reactivity Index [Davis, 1983] for empathy and the Participant role scales [Salmivalli et al., 1996] for bullying and defending behavior. The results revealed that the model fitted the data adequately, but only in the case of boys. As hypothesized, low levels of empathic responsiveness were associated to students' involvement in bullying others. In contrast, empathy was positively associated with actively helping victimized schoolmates. However, the estimates algorithm did not reach convergence with girls' data. The current findings confirm and extend the literature on the relation between empathy, prosociality and aggressive behavior. Educational implications are also discussed.  相似文献

The attractiveness bias suggests that people who are more attractive will be positively favored across life outcomes. This study sought to test whether candidate attractiveness, sex, and race, affect perceptions of candidate strength in a job recruitment task. In total, 338 White women (Mage = 20.94 ± 5.65) were asked to make judgements of a potential candidate for an administrative job (resume with candidate photograph). The vignettes differed in terms of candidate ability (strong/weak), sex (male/female), race (Black/White), and attractiveness (attractive/less attractive). Participants rated perceived candidate strength and likelihood to invite for interview. Results showed no significant main effects for attractiveness. However, there was a significant interaction for target attractiveness and race, such that attractive/White candidates were more likely to be invited for interview than less attractive/White candidates. There was also a significant main effect for race such that Black candidates were rated as stronger and more likely to be interviewed. Sensitivity analyses (with nonheterosexual women removed from the sample) also showed a main effect for target sex such that female candidates were favored over male candidates. Overall, these findings provide evidence that attractiveness, sex, and race have important, albeit complex, effects on hiring decisions in the workplace.  相似文献

Research has previously demonstrated that perceptions of peer's teen dating violence (TDV) is associated with one's own perpetration of TDV, although little research has examined whether this relationship is consistent across developmental time periods (i.e., mid‐to‐late adolescence). The present study examined whether changes in perceptions of peer's TDV predicted change in one's own perpetration of TDV in a sample of ethnically diverse adolescents from ages 15 to 18 (N = 1,042). Parallel process modeling demonstrated that decreases in perceptions of peer's TDV predicted decreases in TDV perpetration over time, and this relationship was more pronounced for males than females. These findings lend further support to the need for TDV prevention and intervention programs to include peer influence in their programs.

BackgroundOlder adults appear to have different activity preferences (prefer to be active alone or with others, or show no preference). As the activity of older females is often associated with social influences (i.e., how others influence the behavior or thoughts of another), understanding how activity preference might interact with social influences becomes important.ObjectivesThis study explored whether activity preferences would moderate the social influence – physical activity relationship in older females.MethodsThe sample for this study was 102 older females with the majority (87%) classified as ‘maintainers’. Using a cross-sectional approach, participants completed questionnaires on social influences by channel (family, friends, healthcare workers) and type (modeling, compliance, conformity, obedience), activity preferences, and physical activity.ResultsMANOVA and follow-up results revealed that friends-modeling (F (2, 99) = 8.15, p < .01) and friends-compliance/conformity (F (2, 99) = 9.82, p < .01) were greater in individuals who preferred to be active with others than those who preferred to be active alone. Results from a hierarchical multiple regression examining activity preferences as a moderator were significant (R2change = .11). For those who preferred to be active with others, friends-modeling was positively related to activity (b = 1.28). For individuals with no activity preference, activity was positively related to friends-compliance/conformity (b = 1.38) and negatively related to friends-modeling (b = ?1.56).ConclusionResults provide preliminary evidence that activity preferences appear to moderate the relationship between the influence of friends and activity in older females, especially for those who are activity maintainers.  相似文献

Two related questions regarding presidential leadership are addressed. First, what are the principal determinants of the rated greatness of American presidents? Second, can presidential performance be predicted using preelection biographical variables? Reliable measures of greatness and performance were operationalized for the 38 presidents of the United States, along with numerous potential predictors suggested by past literature on leadership, achieved eminence, and presidential popularity and greatness. About 75% of the variance in presidential greatness can be predicted using administration duration, number of war years, unsuccessful assassination attempts, scandals, and prepresidential publication record. Family background, personal characteristics, education, occupation, and political experiences provided few if any viable predictors of presidential performance, although succession to office through the vice-presidency exerted a rather general negative impact.  相似文献

The purpose of the study was to reconcile the contradictory evidence reporting either a shortening or lengthening of the simple reaction time (RT) as a function of the intensity of a warning signal. The lengthening of auditory RT is obtained when short visual or auditory warning signals are of constant intensity within a session and succeeded by a fore-period. Visual RT did not vary under similar circumstances. There was no effect when a warning signal of constant intensity overlapped in time with the response stimulus. The shortening of RT occurred with auditory warning signals of variable intensity and overlapping in time with the response stimulus. The shortening of RT was interpreted as facilitation-by-arousal. The lengthening of RT is a contextual effect but the data do not support accounts based on sensory-neural adaptation or criterion changes.  相似文献
