Low sensation seeking and loneliness have been associated with collegiate Internet dependence. In an attempt to further explicate the factors associated with collegiate Internet dependence, interpersonal shyness (both online and in face-to-face [FTF] interactions) was explored. An online questionnaire was used to assess Internet dependency and shyness. The results demonstrated the predicted interaction such that shyness level for nondependents did not differ online or in FTF interactions. However, dependents' shyness was greater in FTF interactions relative to online interpersonal exchanges. The results were discussed in terms of how various Internet resources (e.g., e-mail, chat rooms, and instant messages) can be used to ameliorate shyness and how such negatively reinforced behavior could foster dependence. 相似文献

Much research has been conducted aimed at the representations and mechanisms that enable learning of sequential structures. A central debate concerns the question whether item-item associations (i.e., in the sequence A-B-C-D, B comes after A) or associations of item and serial list position (i.e., B is the second item in the list) are used to represent serial order. Previously, we showed that in a variant of the implicit serial reaction time task, the sequence representation contains associations between serial position and item information (Schuck, Gaschler, Keisler, & Frensch, 2011). Here, we applied models and research methods from working memory research to implicit serial learning to replicate and extend our findings. The experiment involved three sessions of sequence learning. Results support the view that participants acquire knowledge about order structure (item-item associations) and about ordinal structure (serial position-item associations). Analyses suggest that only the simultaneous use of the two types of knowledge acquisition can explain learning-related performance increases. Additionally, our results indicate that serial list position information plays a role very early in learning and that inter-item associations increasingly control behavior in later stages. 相似文献

Action-specific effects on perception are apparent in terrestrial environments. For example, targets that require more effort to walk, jump, or throw to look farther away than when the targets require less effort. Here, we examined whether action-specific effects would generalize to an underwater environment. Instead, perception might be geometrically precise, rather than action-specific, in an environment that is novel from an evolutionary perspective. We manipulated ease to swim by giving participants swimming flippers or taking them away. Those who estimated distance while wearing the flippers judged underwater targets to be closer than did participants who had taken them off. In addition, participants with better swimming ability judged the targets to be closer than did those with worse swimming ability. These results suggest perceived distance underwater is a function of the perceiver's ability to swim to the targets. 相似文献

The present study evaluates the role of distinct components of nicotine dependence (craving, withdrawal, behavioural dependence) in comparison to smoking-related cognitions (attitudes, perceived social approval, self-efficacy) in adolescent smoking cessation. In the process towards smoking cessation, we distinguish between distinct behavioural transitions, respectively, short-term abstinence, reduction in smoking behaviour and prolonged cessation, to evaluate differences in cessation-related antecedents as a function of varying behavioural outcomes. A total of 850 adolescent smokers (age 14-16) participated in the present study. Smoking behaviour was assessed 1 year after baseline. Results showed that all dependence components had a distinct role in the prediction of behavioural change towards cessation. Furthermore, each behavioural transition was predicted by a distinct set of variables, indicating that contributions of cessation-related factors vary across the course towards cessation. Overall, our findings suggest that smoking-related cognitions are particularly relevant in the initiation of behavioural change, such as short-term abstinence, whereas nicotine dependence, craving in particular, becomes increasingly important in the prediction of maintained behavioural change, such as prolonged cessation. Implications encompass enhanced attention to the multidimensional nature of nicotine dependence and the value of comparing different behavioural outcomes in a comprehensive understanding of cessation-related factors. 相似文献

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Through his development of Rational Emotive Behaviour Therapy (REBT), Albert Ellis was a major contributor to the development
of cognitive behaviour therapy. This article reviews key aspects of REBT, the distinction between unhealthy and healthy emotions,
and the role irrational and rational beliefs play in relation to these emotions. As with other areas of psychology, the focus
of REBT over the years has been dominated by negative emotional experiences. In an attempt to address this and further develop
REBT, the present article reviews recent claims from the realm of social psychology that positive illusions promote mental
health. Consequently, it is proposed that a similar dichotomy of healthy and unhealthy positive emotions also exists, and
a basic framework for working with this positive dichotomy is introduced. 相似文献

This two‐sample investigation examined the influence of perceived resources on the form and magnitude of the relationships between accountability for others (AFO) and job tension and job satisfaction. Employing resource theory, we hypothesized that the non‐linear relationship between AFO and job tension would surface only for individuals high in perceived resources, whereas the association between these constructs would be positive and linear for individuals low in perceived resources. A similar relationship was hypothesized for AFO and job satisfaction in which the non‐linear effect would arise for individuals high in perceived resources, and negative linear effects would emerge for those low in perceived resources. Data from two samples (N= 201; N= 182) provided support and replication for the hypotheses. Implications of the results and directions for future research are discussed. 相似文献

OBJECTIVE: The purpose of this paper was to describe the rationale, data collection, and proposed analyses for examination of mediators of change in physical activity from pregnancy to postpartum among a cohort of pregnant women. METHOD: The Pregnancy Infection and Nutrition 3 (PIN3) Study enrolled 2006 pregnant women into the cohort from 2001 to 2005. All women lived in central North Carolina upon enrollment. Physical activity was assessed using a self-reported one week recall, measured twice during pregnancy and once each at 3- and 12-months postpartum. On a subset of women, one-week accelerometer measures were also collected during the two postpartum time periods. Potential mediators (intrapersonal, interpersonal, community) were collected during pregnancy and postpartum through interviews and take home questionnaires. RESULTS: To assess mediation of physical activity among our cohort, we will first describe change in physical activity and the mediators, as well as their associations, through pregnancy into the postpartum period. Following this, the product of coefficients approach will be applied to examine whether each measure had indirect effects on change in physical activity. Each individual level mediator will be examined one at a time and across the time points in which it was available. The Sobel standard error approximation formula will be used to test for significance of the mediation effect. CONCLUSIONS: This study will provide evidence to develop appropriate interventions targeted at physical activity and will help focus efforts on the appropriate time periods between pregnancy and postpartum. 相似文献
