决策者角色及相关因素对风险偏好的影响

两个实验考察了金钱和时间决策中决策者角色及相关因素对风险偏好的影响。结果发现:(1)两种决策中不同决策者角色都会引起风险偏好反转,人们在为他人决策时更偏向于风险寻求;(2)两种决策中风险偏好的反转都会受到任务框架、风险概率的影响,金钱决策中风险偏好的变化还受金钱数额高低的影响。金钱决策中存在决策者角色×任务框架×风险概率之间的交互作用,时间决策中没有发现这种交互作用。     

决策者角色及相关变量对风险偏好的影响

采用IAT技术测查被试的内隐自尊, 并引入收益和损失两种任务框架, 综合探讨了内隐自尊水平、任务得失框架对自我决策和为他人决策时风险偏好的影响。结果发现：(1)在收益框架下, 被试为他人决策时更冒险, 而在损失框架下, 为自我和他人决策的风险偏好无显著差异; (2)与为自我决策相比, 低内隐自尊者为他人决策时更冒险, 而高内隐自尊者为自我和他人决策的风险偏好无显著差异; (3)内隐自尊水平与任务框架的交互作用及内隐自尊水平、任务框架和决策者角色之间的三级交互作用均不显著。依据相关的理论和发现对这种结果进行了分析和讨论。     

事件后信息影响目击证言准确性的实验研究

本研究探讨了不同案件类型、不同性别及给予不同的事件后信息对目击证言的影响,征集了男女大学生被试101名,进行了实验研究,研究结果如下:(1)以主体信息的记忆成绩为因变量,性别、案件类型和事件后信息为白变量,得出案件类型主效应显著,事件后信息的主效应显著,性别主效应以及各因素的交互作用都不显著;(2)以情境信息的记忆成绩为因变量,性别、案件类型和事件后信息为自变量,得出事件后信息主效应显著,案件类型和事件后信息之间交互作用效应显著;(3)不同性别、接受不同案件信息的被试对不同信息记忆的确信程度有所不同.     

关系密切程度以及思维方式和决策风格对风险偏好的影响

研究目的:探讨救援决策者与被救援者的关系密切程度以及思维方式与决策风格对风险偏好的影响。研究方法:实验一采用3(关系密切程度:高、中、低)×2(思维方式:直觉性、分析性)两因素混合实验设计,被试68名;实验二采用3(关系密切程度:高、中、低)×2(思维方式:直觉性、分析性)×2(决策风格:直觉型、分析型)三因素混合实验设计,被试93名。研究结果:(1)救援决策者与被救援者的关系密切程度越高,风险偏好越高;(2)直觉性和分析性思维方式之间的风险偏好无显著差异;(3)直觉型决策风格的风险偏好显著高于分析型;(4)关系密切程度与思维方式的交互作用显著,具体而言,采用直觉性思维方式时,关系密切程度的效应显著,关系密切程度越高,风险偏好越高;采用分析性思维方式时,关系密切程度的效应不显著。结论:直觉与风险偏好的关系更密切。面对关系亲密的被救援者,决策者采用直觉性思维方式时的风险偏好较高。     

真实和虚拟金钱奖赏影响风险决策行为*

在风险情境下人类如何决策是长久以来心理学和经济学研究中一个极具挑战性的核心问题。众多研究采用真实或虚拟金钱作为奖赏强化物来探索风险决策行为的过程和机制,但对金钱奖赏真实性如何影响决策了解很少。仿真气球冒险任务(BART：Balloon Analogue Risk Task)可以在实验室条件下有效评估个体在真实社会中的风险行为。本研究采用 BART任务,通过两个实验探讨和比较了真实与虚拟金钱奖赏对风险决策行为的影响。实验一的结果发现,与虚拟金钱奖赏相比,真实金钱奖赏情境下的风险决策更容易受上一次决策结果的影响,上一次决策失败会导致被试的风险偏好水平显著降低(平均吹气球的次数显著减少),同时决策失败(气球吹爆)次数也显著减少,提示真实金钱奖赏下有更强的反馈学习效应。实验二重复了实验一的结果,并进一步发现,虚拟金钱奖赏的幅度对被试的风险决策行为没有影响,而真实金钱奖赏的幅度能显著改变被试的风险决策行为,较大幅度的真实金钱奖赏可以显著降低被试的风险偏好水平,但这种奖赏幅度对风险偏好的调控效应只对感觉寻求水平低的被试有效,感觉寻求水平高的被试不受影响。这些发现表明真实与虚拟金钱奖赏对风险决策行为有不同的影响。我们的结果可以用风险决策的后悔理论或齐当别模型来解释。     

初中生风险决策表现的认知建模分析:自尊及性别的影响

选取山东省某初中308名学生,采用爱荷华博弈任务,使用“效用-固着”模型对决策包含的动机、认知、反应心理过程进行认知建模分析,探究自尊水平和性别对初中生风险决策表现的影响。结果发现,初中生的风险决策表现不佳,对损失不敏感。在控制年级的影响后,分层回归分析表明:(1)自尊水平和性别对决策的动机过程的影响存在交互作用,男生无论自尊高低对收益都较为关注,女生中高自尊者更加关注收益。(2)决策成绩不存在显著的性别差异,但男生更多选择有着较高损失值的不利选项,而女生更多选择损失频率较低的有利选项。(3)自尊的影响主要体现在动机和认知过程,高自尊水平者在动机过程中更多表现出对损失的规避,在认知过程中更多地考虑维持之前的决策选择。     

青少年负性情绪信息记忆偏向的情绪弹性和性别效应

为了探讨情绪弹性和性别变量对青少年再认记忆负性情绪信息的影响,该实验采用再认记忆测验范式,以49名青少年为被试,以负性情绪图片为实验材料,考察了不同情绪弹性和性别的青少年再认负性情绪图片时的错误率差异。结果发现,情绪弹性对再认记忆负性情绪图片的主效应显著,统计效力明显。性别对再认记忆负性情绪图片的主效应显著,统计效力明显。情绪弹性与性别在再认记忆上的交互作用不显著。这说明青少年负性情绪信息加工过程中产生的记忆偏向效应受情绪弹性和性别因素的影响。     

3～8年级学生羞怯与心理适应之关系:一个有中介的调节模型检验

以1485名3-8年级学生为研究对象,借助同伴评价和自我报告,考察性别对羞怯和心理适应关系的调节效应以及同伴关系不良在上述调节效应中的中介作用。研究结果表明:(1)羞怯、同伴关系不良、孤独和抑郁的性别差异显著。女孩的羞怯水平显著高于男孩,而同伴关系不良、孤独、抑郁水平则显著低于男孩;(2)羞怯与同伴关系不良、孤独、抑郁呈较弱的正相关,而与自尊呈较弱的负相关;(3)羞怯与孤独、抑郁、自尊的关系受性别因素的调节,羞怯男孩面临的心理适应风险高于羞怯女孩;(4)性别对羞怯和孤独、抑郁、自尊关系的调节通过同伴关系不良这一中介因素而实现,间接效应占总效应的比例在25%至47%之间。这一结果表明,羞怯的适应价值存在性别差异,而同伴关系在其中扮演着重要的中介角色。     

内隐自尊和风险偏好对大学生职业决策的影响

为研究影响大学生职业决策的影响因素和决策有效性,实验一、二分别从决策者心理特征（内隐自尊与风险偏好）和职业方案特征（框架效应与风险水平）入手,考察二者对大学生职业决策行为的影响。结果发现：内隐自尊和风险偏好的高低显著影响大学生择业倾向性;大学生对风险水平不同的职业方案的选择倾向由低到高依次为冒险、折中、保守方案;职业决策存在明显的框架效应。研究表明,大多数大学生倾向于选择保守的职业方案;高风险偏好的大学生倾向于选择冒险的职业方案;高内隐自尊大学生倾向于主动择业;积极表述的职业方案更受大学生所青睐。     

自尊对失败后抑郁、焦虑反应的缓冲效应

以117名大二学生为被试,采用问卷调查与实验相结合的方法,考察了自尊对失败后的抑郁状态、焦虑状态两种不良情绪反应的缓冲效应。结果发现：(1)无论何种情况下,高自尊组的被试其抑郁和焦虑反应都明显少于低自尊组;(2)失败程序成功诱导了被试的抑郁和焦虑反应;(3)失败后,自尊并没有立即或直接缓冲被试的抑郁和焦虑反应;(4)策略处理后,自尊显著缓冲了两种不良情绪反应,且在不同条件下有不同的效果;但自尊水平与策略处理间的总体交互作用不显著。     

母亲男孩偏好和亲子沟通的关系:子女性别的调节作用

以653名小学五年级学生的母亲为被试,通过问卷法探讨了母亲男孩偏好和母子亲子沟通的关系,并考察子女性别在其中可能的调节作用。结果表明：（1）子女为非独生、流动儿童;受教育水平较低、家中有2个及以上孩子以及所测查的孩子排名第2及以上孩子的母亲具有较高水平的男孩偏好;（2）子女性别对于母亲男孩偏好和母子亲子沟通关系的调节作用显著。对女生而言,亲子沟通随着母亲男孩偏好的增加而显著下降;对男生而言,母亲男孩偏好并不能显著预测亲子沟通。结果揭示了母亲男孩偏好对于母女亲子沟通的负面影响,提示了在强调男女平等的背景下,男孩偏好依旧值得重视并着力改善,特别是在孩子人格塑造和习惯养成的关键时期,作为主要照料者的母亲更应得到关注。     

Gender Differences in Adolescent Self-Esteem: An Exploration of Domains

The relationship between gender and global self-esteem in adolescence, while modest, has been well established, with boys consistently scoring higher than girls. In the present study, we sought to understand gender differences in adolescent self-esteem in terms of its component parts. With a relatively large (n = 545) sample of adolescents, drawn from Grades 8, 10. and 12, we specified 8 domains of adolescent self-esteem (personal security, home/parents, peer popularity, academic competence, attractiveness, personal mastery, psychological permeability, and athletic competence) across a number of different instruments and brought them together into a common assessment superstructure. Gender differences as well as the relative contributions of the different domains to overall self-esteem scores were measured. As predicted, boys attained slightly higher global self-esteem scores than girls did, by a difference of .22 standard deviation units. Contrary to our expectation of more balanced domain effects, boys significantly outperformed girls in 6 of 8 domains, whereas the 2 remaining domains exhibited no significant gender differences. There were no main or interaction effects for grade level. In terms of relative contribution of these domains to global self-esteem for the 2 genders, global self-esteem in boys and girls is predicted in very similar strengths and in the same order of magnitude by identical domains of self-esteem: home/parents, personal security, academic competence, attractiveness, and personal mastery—yielding multiple R ²s from .88 to .91.     

任务类型和性别属性对人际信任的影响

研究应用投资游戏任务及其变式,探讨了任务类型与性别属性对人际交往过程中信任给予和信任维持的影响。24名被试(平均年龄为20.41±1.99)通过轮组,完成了实验一和实验二的投资游戏任务。通过对投资比、返还比及其关系的比较和分析,结果发现:(1)在风险任务中,不同性别信任者的信任给予存在显著性差异,而且信任对象的性别属性对信任者的信任给予也存在显著性影响。(2)在无风险任务中,性别属性对信任对象的信任维持行为不存在显著影响,而信任者的信任给予对信任对象的行为具有显著的预测作用。这一结果表明,性别属性对人际信任的影响,与任务的风险性有关。     

The relation between low self-esteem and depressive mood in a non-clinical sample: The role of gender and negative life events

The suggestion that self-esteem is both a protective and a risk factor for depression is well documented. However, this association is not consistently observed by empirical research. The current study investigated the main and interactive effects of low self-esteem and stressful life events on depressive mood in a sample of university students (N = 862; female = 72%; black = 67%; mean age = 21.70, SD = 13.51). The students completed the Hopkins Symptom Checklist, the Rosenberg Self-Esteem Scale, and the Perceived Stress Scale. Data were analysed using structural equation modelling (SEM); with stressful life events scores as a mediator, and gender as a moderator, of the relation between low self-esteem and depression. Results indicate that low self-esteem significantly predicted depression, and that stressful life events partially mediated that relationship. Support emerged for the vulnerability effects of low self-esteem on depression and they held across gender groups. Low self-esteem may be a significant indicator of individuals who are at risk for developing depressive mood.     

高中生自我调节学习与自尊:感知教师支持及性别的调节作用

采用自我调节学习问卷、感知教师支持问卷及自尊问卷,对334名高中生进行测量,探究感知教师支持及性别在自我调节学习与自尊之间的调节作用。结果表明:(1)自我调节学习与自尊呈显著正相关,感知教师支持与自尊及自我调节学习呈显著正相关;(2)感知教师支持及性别在自我调节学习与自尊之间均起调节作用:自我调节学习对自尊的影响在女生中更为明显,感知高水平的教师支持缓解了低自我调节学习对自尊的负面影响。     

内隐性别刻板印象与自尊的关系研究

为了考察内隐性别刻板印象的存在广度,以及探讨它与自尊的关系,本研究采用内隐联想测验(IAT)和自尊量表(SES)考察65名大学生被试的内隐性别刻板印象和自尊水平,得出以下结论:一、大学生中普遍存在着内隐性别刻板印象,并且不同性别的内隐性别刻板印象不具有显著差异。二、有内隐性别刻板印象的人群中,不同性别的自尊水平差异不显著。三、内隐性别刻板印象与个体自尊水平的相关不显著。     

Gender Segregation in Childhood: A Test of the Interaction Style Theory

The authors investigated the play/interaction-style theory of gender segregation with a sample of 39 children aged 2 to 5 years (primarily Caucasian). According to this theory, children prefer playmates with styles of play or interaction that are similar to their own. Because such styles are sex differentiated, same-sex playmate preference (i.e., gender segregation) results. The authors observed children during free play to determine preferred playmates and gender segregation level, and they used teacher ratings to derive play/interaction-style scores. The authors used a multiple regression approach to path analysis to analyze effects of sex of participant, participants' play/interaction-style scores, playmates' play/interaction-style scores, and degree of gender segregation to determine their effects on one another. The authors observed significant levels of gender segregation, with highly aggressive or active children displaying less segregation than their peers did. However, gender segregation was not associated with a preference for playmates with similar play or interaction styles.     

Implicit self-esteem compensation: automatic threat defense

Four experiments demonstrated implicit self-esteem compensation (ISEC) in response to threats involving gender identity (Experiment 1), implicit racism (Experiment 2), and social rejection (Experiments 3-4). Under conditions in which people might be expected to suffer a blow to self-worth, they instead showed high scores on 2 implicit self-esteem measures. There was no comparable effect on explicit self-esteem. However, ISEC was eliminated following self-affirmation (Experiment 3). Furthermore, threat manipulations increased automatic intergroup bias, but ISEC mediated these relationships (Experiments 2-3). Thus, a process that serves as damage control for the self may have negative social consequences. Finally, pretest anxiety mediated the relationship between threat and ISEC (Experiment 3), whereas ISEC negatively predicted anxiety among high-threat participants (Experiment 4), suggesting that ISEC may function to regulate anxiety. The implications of these findings for automatic emotion regulation, intergroup bias, and implicit self-esteem measures are discussed.
