The purpose of this study was to measure the self-esteem, stress of life events, and locus of control among unemployed and employed blue-collar workers. It was hypothesized that (a) being unemployed decreases an individual's self-esteem, (b) being unemployed increases an individual's stress level by experiencing significant life changes, and (c) being unemployed increases an individual's external locus of control orientation. The study was conducted in a production/manufacturing organization, utilizing a systematic random sampling procedure that yielded 562 subjects. The results from the collected data did not support Hypothesis A or C. A significant change with stress in conjunction with life events was found but was mediated by several factors, including age and a nonsignificant correlation between time laid-off and stress levels. The study suggests that an individual's reaction to unemployment does not appreciably affect their self-esteem and locus of control when compared to the employed. 相似文献

Thirty left-handed and right-handed Ss (10 each from the second grade, fifth grade, and college) were compared on four subtests of the Torrance creativity test. At each age level, left-handed students had higher creativity scores than right-handers. The greatest differences were found on the Elaboration subtest. 相似文献

Studies of electrophysiological indices of performance monitoring, such as the error-related negativity (ERN), posterror positivity
(Pe), and N2 components of the event-related potential (ERP), suggest that increased ERN and Pe amplitudes and decreased N2
amplitudes are associated with better cognitive flexibility and cognitive control abilities; however, few studies have directly
examined the relationship between cognitive performance and ERP indices of performance monitoring. We examined the neuropsychological
profile of 89 healthy individuals who performed a modified flanker task. The neuropsychological domains tested included memory,
verbal fluency, and attention/executive functioning. Pearson’s correlations and multiple regression analyses showed a significant
relationship between measures of attention/executive functioning and ERN amplitude, even when negative affect, reaction time
interference, and posterror slowing were controlled. N2 amplitude related only to posterror slowing. The amplitude of the
Pe was not significantly related to any cognitive domains. These findings are consistent with recent work indicating that
performance monitoring requires attention skills and cognitive flexibility. Implications for the conflict-monitoring and reinforcement-learning
theories are discussed. 相似文献

Perception of attractiveness by obesity and hair color 总被引:1,自引:0,他引:1
In a study of 318 Caucasian college students, obese persons and redheaded men were seen as unattractive compared to the nonobese and other hair colors. The obesity stereotype and the hair-color stereotype appear to be evaluated separately with little interaction. The results imply that a stereotypic characteristic like obesity, which is perceived as being under a person's control, may be evaluated differently than a stereotypic characteristic independent of personal choice such as hair color. 相似文献

The majority of individuals exposed to trauma do not go on to develop posttraumatic stress disorder (PTSD); thus, researchers have sought to identify individual difference variables that make one particularly susceptible to posttraumatic stress symptoms. Trait anxiety is one individual difference variable implicated in the pathogenesis of posttraumatic stress symptoms. Following from cognitive theories of anxiety and extant data, the purpose of the present study was to examine executive attention as a moderator of the relation between trait anxiety and posttraumatic stress symptoms, particularly hyperarousal symptoms, among undergraduate women reporting trauma exposure (N = 88). As predicted, executive attention moderated the association between trait anxiety and hyperarousal symptoms, such that there was a significantly weaker relation as executive attention increased. Study results further support the potential buffering effect of executive attention in relation to posttraumatic stress symptoms, as well as the possible importance of targeting executive attention following trauma exposure. 相似文献
