味觉对判断与决策的影响及其机制

味觉作为人类生存必不可少的感觉之一, 早已超越“舌尖”的直接感受, 潜在地影响了个体对人际关系及伦理道德的知觉与判断, 改变着个体对冒险与消费等行为的决策。情绪中介假说、具身隐喻假说、进化假说以及社会建构假说从不同视角试图阐明味觉对判断与决策的影响机制。当前研究存在味觉感受存在个体差异、味觉测量难以保证效度、味觉实验缺乏统一研究范式等问题, 未来可继续进行味觉隐喻的验证并将其应用于感官营销、心理治疗等领域, 从生理、心理及社会等多个层面出发, 全方位探讨味觉对判断、决策的影响及其机制。

温水煮青蛙：专业认同对大学生抑郁的影响机制

为探讨专业认同、学业情绪与大学生抑郁之间的关系,采用大学生专业认同问卷、青少年学业情绪问卷与抑郁自评量表对329名大学生进行调查。结果发现：（1）专业认同对大学生抑郁有显著负向预测作用;（2）专业认同对积极学业情绪均有显著正向预测作用,但只对消极低唤醒学业情绪有显著负向预测作用;（3）在专业认同对抑郁的影响中,积极低唤醒与消极低唤醒学业情绪起到完全中介作用。结果表明,专业认同对大学生抑郁的影响实际上是一种“温水煮青蛙”效应。     

负折扣现象:跨期决策中的自我-他人决策差异

负折扣现象作为一种违背时间折扣假定的现象越来越多地引起研究者关注。本文通过两种指标考察了为自己决策和为他人决策在负折扣现象上的差异。实验1运用二择一选择范式考察人们在为自己决策和为他人决策时对于何时发生负性事件的时间偏好。结果发现,相比较于为他人决策,为自己决策时被试更倾向于选择早些发生负性事件,即更容易产生负折扣现象。实验2运用测量时间折扣率的经典范式考察了人们在为自己决策和为他人决策时的时间折扣率。结果发现,为自己决策时比为他人决策时的时间折扣率更小,更容易出现负折扣率。总体结果表明,为自己决策比为他人决策更容易出现负折扣现象。从情绪卷入的角度看,我们推测,为自己决策时由于更多的预期负性情绪卷入,从而导致更容易产生负折扣现象。     

幸福的体验效用与非理性决策行为的偏差机制

基于体验效用的幸福包括预期幸福、即时幸福和回忆幸福,这三者有极其重要的本质差异,导致决策偏差和非理性。本研究运用行为科学和认知神经科学相结合的研究方法,首次从行为层次—信息加工层次—脑神经层次三个层面,立体地开展幸福感的体验效用与非理性决策行为研究。研究计划分为三个部分:(1)预期幸福、即时幸福和回忆幸福的本质特点和行为规律;(2)三种体验效用产生偏差的认知心理机制;(3)体验效用与非理性决策偏差的脑神经机制。通过系列研究,拟解决三个关键问题:(1)在人类判断与决策过程中,预期、即时和回忆三种效用是如何影响人们的判断与决策?(2)三种体验效用出现偏差的信息加工特点和脑神经机制究竟是什么?(3)三种效用的偏差规律及对政府公共政策的启示。对这些问题的深入探讨,不仅对决策理论研究的发展是一个贡献;对政府管理制定有效的公共政策,避免"牺牲体验追求指标",解决"幸福悖论",同样有很强的实践指导意义。     

Prediction of toddlers’ expressive language from maternal sensitivity and toddlers’ anger expressions: A developmental perspective

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.     

Negotiating safer sex: A detailed analysis of attitude functions,anticipated emotions,relationship status and gender

Objective : Because interpersonal discussion about condom use can encourage subsequent condom use, this project aims to examine the psychological antecedents of intentions to discuss or request the use of condoms with a sexual partner.

Method : The data were collected from 849 heterosexual college students in the USA through an online survey. The survey contained several measures related to attitude functions (i.e. motivations), efficacy, norms and intentions to discuss condom use with a sexual partner.

Results : Participants’ attitude functions weakly predicted intentions to discuss condom use. Communication efficacy was a more important predictor of intentions for females (vs. males) and for those in other relationships or not in a relationship (vs. long-term monogamous relationships). Anticipated negative emotions were a stronger predictor of intentions for those in long-term monogamous relationships (vs. other relationships or not in a relationship).

Implications : Future research needs to consider more detailed attitude functions and anticipated emotions. Furthermore, background variables (e.g. gender and relationship status) can be moderators in addition to being distal predictors.     

Capturing the Structure of Distinct Types of Individual Differences in the Situation‐specific Experience of Emotions: The Case of Anger

The aim of this paper was to understand why some people experience certain emotions in a specific situation, whereas others do not. We postulate that these individual differences arise from individual differences in two underlying processes of emotion elicitation: (i) individual differences in the emotion components (appraisals and action tendencies) that situations activate in a person and (ii) individual differences in how these emotion components are related to subjective emotional experience. In this paper, we re‐analysed data from two studies on anger to capture the structure of these two types of individual differences by using clustering modelling techniques. Consistent results across the two studies demonstrated that individuals differ in anger because they (i) differ in how easy they experience anger‐relevant appraisals (Studies 1 and 2) and action tendencies (Study 2) in increasingly negative situations and (ii) differ in which of these components are necessary to experience anger.

The role of intuition in entrepreneurship and business venturing decisions

Entrepreneurial intuition is the affectively charged recognition and evaluation of a business venturing opportunity arising as a result of involuntary, rapid, non-conscious, associative processing. This article integrates theories of dual-processing and models of the business venturing (opportunity recognition, evaluation, and exploitation) in a model of entrepreneurial intuition, which links intuitive expertise, cognitive style, somatic state, and the affect heuristic with System 2 interventions and the contingencies of the decision environment. Six research propositions are offered with suggestions for how they can be tested. The theoretical and practical implications of entrepreneurial intuition are discussed in terms of the unfolding of a research agenda relating to this important but under-theorized and under-researched construct in work and organizational psychology.
