Self-leadership and volition are conceptually similar concepts. Both propose self-influence strategies that aim to improve the motivation and self-direction necessary to perform well. The present study assesses whether self-leadership strategies maintain construct-specific variance when compared with the similar strategies of volition. Results from a questionnaire study (N=320) indicate that self-leadership and volitional strategies are distinguishable and only moderately (r = .33) correlated. Self-leadership, therefore, supplements volition during goal attainment. Findings are discussed in light of the Rubicon model of action phases. 相似文献

Two studies analyzed the impact of international exchange programs on students' identity development. More precisely, the authors predict that exchange students integrate the host society (hostgroup) into their self‐concept during an exchange year. Study 1 found a stronger social identification with the hostgroup and higher commitment for former exchange students than for future exchange students. Study 2 replicated the difference between former and future exchange students and found in addition that both former and future exchange students had a stronger identification and commitment in comparison to a control group that did neither take part in nor apply for an exchange program. Moreover, in this study the inclusion of the hostgroup into the self‐concept was assessed via a response time paradigm. The results indicate that former and future exchange students have a stronger association between the self and the hostgroup than the control sample, but no difference between former and future exchange students was found. The results provide evidence for the impact of interest in and actual intensive intergroup contact on students' self‐concept. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

假性甲状旁腺功能减退症是一种罕见的遗传性疾病,由甲状旁腺激素(PTH)抵抗所致。临床特点有低钙高磷血症、血清PTH升高,部分可表现为Albright遗传性骨营养不良症,并伴有多发激素抵抗。分子遗传学研究表明本症与编码Gs蛋白α亚基(Gsα)的GNAS1基因缺陷相关。Gsα的失活性突变导致AHO畸形,而多发激素抵抗可能是由于组织特异性的GNAS1印记缺陷所致。补充钙剂和活性维生素D是有效的治疗方法,基因治疗是未来的研究方向。 相似文献

A new focus in the field of emotional memory is the study of sex-related differences. Whether the sex-related lateralization of amygdala function (i.e., the female-left/male-right effect) in the emotional enhancement of memory (EEM) is time-dependent remains unclear. To evaluate this phenomenon, we conducted a two time-point study (20 min vs. 24 h) using fMRI and behavioral paradigms. We found that the right amygdala predicted 20-min EEM, while the left amygdala predicted 24-h EEM. The sex-related lateralization of amygdala function was not detected in either the 20-min or the 24-h EEM. Our results further confirm and extend the idea that the amygdala exhibits a lateralized and time-dependent dissociation, occurring even in the 24-h EEM relative to the 20-min EEM. The present and previous studies indicate that sex-related lateralization of amygdala function occurs in the 2- to 3-week EEM, but it does not occur in the 1-week, 24-h, or less than 30-min EEM, suggesting that this effect on emotional memory may also be time-dependent. 相似文献

The present investigation examined the effect of sexual objectification on women's intention to affiliate with men. We predicted that women would perceive an objectifier as less likable following sexual objectification and thus would distance themselves from the perpetrator. Study 1 found that objectification led female participants to perceive their male partner as less likable and to be less willing to affiliate with the partner. Study 2 replicated Study 1 in a concurrent interpersonal interaction and extended these effects to a man having a similar background with the perpetrator. Study 3 showed that power moderated the effect of sexual objectification on women's interaction intention such that only women with equal or low power (as compared to the objectifier) decreased their affiliation intention toward the objectifier, whereas high‐power women did not show this effect. Implications of these findings were discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Internet companies collect a vast amount of data about their users in order to personalize banner ads. However, very little is known about the effects of personalized banners on attention and memory. In the present study, 48 subjects performed search tasks on web pages containing personalized or nonpersonalized banners. Overt attention was measured by an eye‐tracker, and recognition of banner and task‐relevant information was subsequently examined. The entropy of fixations served as a measure for the overall exploration of web pages. Results confirm the hypotheses that personalization enhances recognition for the content of banners while the effect on attention was weaker and partially nonsignificant. In contrast, overall exploration of web pages and recognition of task‐relevant information was not influenced. The temporal course of fixations revealed that visual exploration of banners typically proceeds from the picture to the logo and finally to the slogan. We discuss theoretical and practical implications. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Taking a Darwinian approach, we propose that people reason to detect free-riders on the Wason Selection task with the sharing-rule; If one receives the resource, one is an in-group member (standard), or If one is an in-group member, one receives the resource (switched). As predicted, taking the resource-provider's perspective, both undergraduates and children (11 to 12 years old) checked for the existence of out-group members taking undeserved resource. Changing the perspective to that of the resource-recipient did not alter the selection pattern in undergraduates, although the prediction was that another type of free-riding—failure to share by resource-provider—would be checked as well. However, by removing confounding factors in the materials, both undergraduates and children checked for both types of free-riding, which fully supports the prediction. These results indicate that the sharing-rule elicits a thematic content effect that cannot be explained by preceding deontic reasoning theories. 相似文献

Presentation of maternal stimuli to an isolated rat pup results in what has been called “comfort” responses, as indicated by both behavioral and physiological quieting. This experiment investigated the role of passive maternal stimuli on tonic immobility and dorsal immobility in 9- and 15-day-old rat pups. Although these stimuli appeared ineffective in inducing tonic immobility, presentation of the mother did produce an increase in duration of dorsal immobility in 15-day-old pups. This increase in the dorsal immobility response may reduce struggling in the presence of the mother and thereby aid the mother in transporting the infant back to the nest. 相似文献

Philosophical interest in the role of self-locating information in the confirmation of hypotheses has intensified in virtue of the Sleeping Beauty problem. If the correct solution to that problem is 1/3, various attractive views on confirmation and probabilistic reasoning appear to be undermined; and some writers have used the problem as a basis for rejecting some of those views. My interest here is in two such views. One of them is the thesis that self-locating information cannot be evidentially relevant to a non-self-locating hypothesis. The other, a basic tenet of Bayesian confirmation theory, is the thesis that an ideally rational agent updates her credence in a non-self-locating hypothesis in response to new information only by conditionalization. I argue that we can disprove these two theses by way of cases that are much less puzzling than Sleeping Beauty. I present two such cases in this paper. 相似文献
