慢性应激事件对第三方惩罚的影响及其个体差异

本研究以法学和非法学学生为被试,重大考试为慢性应激源,考察意图和结果不同的法律情境下,慢性应激对第三方惩罚的影响。结果发现：(1) 意图清晰度和结果严重程度显著预测惩罚强度;(2) 法学被试中,慢性应激增加惩罚倾向,当案件意图模糊结果轻时,负性情绪在应激和惩罚强度间起中介作用;(3) 应激对第三方惩罚的影响受他人视角下的个体公正敏感性的调节。本研究有助于更好理解应激对社会决策的影响,也为司法实践提供了参考。     

An epistemology for practical knowledge

Anscombe thought that practical knowledge – a person’s knowledge of what she is intentionally doing – displays formal differences to ordinary empirical, or ‘speculative’, knowledge. I suggest these differences rest on the fact that practical knowledge involves intention analogously to how speculative knowledge involves belief. But this claim conflicts with the standard conception of knowledge, according to which knowledge is an inherently belief-involving phenomenon. Building on John Hyman’s account of knowledge as the ability to use a fact as a reason, I develop an alternative, two-tier, epistemology which allows that knowledge might really come in a belief-involving and an intention-involving form.     

经颅直流电刺激右侧颞顶联合区对道德意图加工的影响*

对行为意图的理解是人类进行道德判断的重要依据,大量研究表明,右侧颞顶联合区是意图加工的关键脑区。为考察该脑区在道德判断中的重要作用,采用经颅直流电刺激技术阳极刺激右侧颞顶联合区,探讨促进该脑区的活动对被试在道德判断中意图及相关信息加工的影响。结果发现与假刺激条件相比,阳极刺激后道德判断反应时显著延长,在伤人未遂和意外伤人条件下差异显著,证明促进右侧颞顶联合区的激活能影响道德判断中的意图加工,尤其在意图与结果产生冲突的条件下效应更加显著。     

Habit as both a direct cause of intention to use a condom and as a moderator of the attitude-intention and subjective norm-intention relations

Abstract

Undergraduates at an American university were asked questions about their attitudes, subjective norms, habits, and intentions towards using a condom during sexual intercourse. Consistent with previous research (Chan and Fishbein, 1993; Trafimow, 1994), intentions were well predicted by attitudes and subjective norms (r = 0.88 and r = 0.73, p < 0.01 in both cases). Intentions were also well predicted by habits (r = 0.77, p < 0.01). More interestingly, however, for participants who were in the habit of using condoms, attitudes and subjective norms were not significant predictors of intentions to use condoms in the future (r = 0.18 and r = 0.10, p<0.1 in both cases). In contrast, attitudes and subjective norms were strong predictors for participants who were not in the habit of using condoms (r = 0.81 and r = 0.61, p < 0.01 in both cases). These findings were replicated in a second study.     

Breast cancer: The intention to have a mammography and a clinical breast examination - application of the theory of planned behavior

Abstract

The purpose of these cross sectional studies was to identify the psychosocial factors explaining women's intention to have a mammography within the next two years and their intention to have a clinical breast examination (CBE) by a professional within the next year. Two random samples of women aged 40–69 years (n_a = 354, n_b = 344) completed a self-administered questionnaire that investigated theoretical constructs of the theory of planned behavior. The results of structural equation modeling showed that subjective norms and perceived behavioral control explained 81 % of the variance in intention of having a mammography. Sixty-five percent (65%) of the variance in intention of having a CBE was explained by attitude and perceived behavioral control. In conclusion, women need to be better informed, have better skills to overcome psychological and physical barriers in performing preventive breast behaviors, and promotion of preventive breast cancer methods should consider people significant for women.     

From health beliefs to self-regulation: Theoretical advances in the psychology of action control

Abstract

The paper reviews the theoretical concepts included in a range of social cognitive models which have identified psychological antecedents of individual motivation and behaviour. Areas of correspondence are noted and core constructs (derived primarily from the theory of planned behaviour and social cognitive theory) are identified. The role of intention formation, self-efficacy beliefs, attitudes, normative beliefs and self-representations are highlighted and it is argued that these constructs provide a useful framework for modelling the psychological prerequisites of health behaviour. Acknowledging that intentions do not translate into action automatically, recent advances in our understanding of the ways in which prior planning and rehearsal can enhance individual control of action and facilitate the routinisation of behaviour are considered. The importance of engaging in preparatory behaviours for the achievement of many health goals is discussed and the processes by which goals are prioritised, including their links to self-representations, are explored. The implications of social cognitive and self-regulatory theories for the cognitive assessment of individual readiness for action and for intervention design in health-related settings are highlighted.     

Trying to be happier really can work: Two experimental studies

Does the explicit attempt to be happier facilitate or obstruct the actual experience of happiness? Two experiments investigated this question using listening to positive music as a happiness-inducing activity. Study 1 showed that participants assigned to try to boost their mood while listening to 12?min of music reported higher positive mood compared to participants who simply listened to music without attempting to alter mood. However, this effect was qualified by the predicted interaction: the music had to be positively valenced (i.e. Copland, not Stravinsky). In Study 2, participants who were instructed to intentionally try to become happier (vs. not trying) reported higher increases in subjective happiness after listening to positively valenced music during five separate lab visits over a two-week period. These studies demonstrate that listening to positive music may be an effective way to improve happiness, particularly when it is combined with an intention to become happier.     

Psychological contract breach,affective commitment to organization and supervisor,and newcomer adjustment: A three-wave moderated mediation model

This study examines the relationship of psychological contract breach to newcomer adjustment outcomes using affective commitments to organizations and supervisors as mediators and also looks at the moderating role of affective commitment to supervisors. Drawing from data collected at three points in time among a sample of newcomers (N = 224), we found that Time 2 affective organizational commitment mediated a positive relationship between Time 1 psychological contract breach and Time 3 turnover intention and emotional exhaustion. Moreover, affective commitment to supervisors interacted with organizational commitment such that the latter was more negatively related to Time 3 outcomes at low levels of commitment to supervisors. Similarly, the indirect relationships of psychological contract breach to Time 3 outcomes were stronger and negative at low levels of commitment to supervisors. Affective commitment's role in the psychological contract breach-outcome relationships during the entry period is discussed.     

Contexts of a person's prior intentions facilitate observational learning in 2.5-year-old children

We examined whether contexts suggesting an actor's prior intentions facilitate observational learning in 2.5-year-olds. In Experiment 1, children observed an experimenter handle one box before proceeding to open a second box. In two prior intention conditions, children either watched the experimenter extract a toy from the first box or saw that the box had already been opened. In two no prior intention conditions, children watched the demonstration with only the second box or paired with irrelevant actions upon the first box. Children successfully opened the second box more often in the two prior intention conditions than in the two no prior intention conditions. Experiment 2 investigated stimulus generalization as another explanation for these results. A functionally different trap-tube task served as the pre-demonstration apparatus. Before watching the experimenter open the box, children either saw her extract a toy from the tube with a stick or observed the toy accidentally fall from the opening. In both cases, children opened the box at similar high rates. We discuss children's use of others’ prior intentions or observable outcomes in observational learning.     

社会服务实践对中学生公民行动意向的影响——社会服务观念的中介作用

本研究对6203名参与过不同形式的社会服务实践的中学生进行调查,考察了中学生参与社会服务实践的现状及其对公民行动意向的影响机制。结果发现:(1)我国中学社会服务实践的质量各维度差异较大,内外调控、深化与拓展、课程关联和自主性得分依次显著降低。(2)中学生参与的社会服务实践在城乡、学校类型、年级上存在显著差异,学校类型和年级的交互作用显著。城市、示范学校、低年级的学生参与的社会服务实践的质量较好,示范学校的优势主要体现在低年级阶段。(3)中学生的社会服务实践经历影响其公民行动意向,而社会服务观念在其中起到部分中介作用。高质量的社会服务实践经历有助于改进中学生的社会服务观念,进而增强其公民行动意向。
