心理距离对风险决策框架效应的影响

解释水平理论是一种解释心理距离怎样影响个体的思维决策的社会认知理论。研究基于解释水平理论,探查了心理距离对风险决策框架效应的影响。实验从心理距离的四个维度入手,每个维度均采用2（解释水平高、低）×2（正框架、负框架）的被试间设计,用于检验解释水平是否调节框架对被试决策任务的选择。结果表明,当心理距离越远,解释水平越高时,被试产生明显的框架效应;而当心理距离越近,解释水平越低时,框架效应明显减弱。除了大概率情况下的框架效应削弱至不显著,其余维度的高、低解释水平下的框架效应均显著。     

Global identification,xenophobia and globalisation: A cross‐national exploration

This paper explores the ways in which globalisation influences social identity. Combining a psychological social‐identity framework with sociological considerations regarding the contextual impact of globalisation, it tests whether global identification—that is, people's identification as global citizens—constitutes an inclusive category, negatively linked to xenophobic attitudes towards immigrants across countries and whether the actual country level of globalisation moderates the relationship between global identification and xenophobia. Unlike most psychological studies of globalisation, it draws its data from 124 national samples across 86 countries, with 154,760 respondents overall, using three different cross‐national surveys. Study 1 (International Social Survey Program National Identity Module III 2013; N = 39,426, countries = 32) evinces that while global identification is in fact negatively linked to xenophobia, the correlation is moderated by the country level of globalisation, countries marked by higher levels of globalisation exhibiting a stronger negative relation between global identification and xenophobia than those characterised by a lower level of globalisation. Study 2 (European Values Study 2008; N = 53,083, countries = 44) and Study 3 (World Values Survey 6; N = 65,251, countries = 48) replicated these results across other countries employing dissimilar scales for global identification and xenophobia.     

Do Community Characteristics Relate to Young Adult College Students’ Credit Card Debt? The Hypothesized Role of Collective Institutional Efficacy

This study examines the extent of emergent, outstanding credit card debt among young adult college students and investigates whether any associations existed between this credit card debt and the characteristics of the communities in which these students grew up or lived. Using data (N = 748) from a longitudinal survey and merging community characteristics measured at the zip code level, we confirmed that a community's unemployment rate, average total debt, average credit score, and number of bank branch offices were associated with a young adult college student's acquisition and accumulation of credit card debt. For example, a community's higher unemployment rate and lower number of bank branches were associated with a young adult college student's greater accumulated debt. Community characteristics had the strongest associations with credit card debt, especially after controlling for individual characteristics (i.e., a young adult college student's race and financial independence) and familial characteristics (i.e., their parents’ income and parents’ discussions of financial matters while growing up at home). The findings may help to understand the unique roles that communities play in shaping children and young adults’ financial capability, and how communities can be better capacitated to support the financial goals of their residents.     

回忆任务对合作抑制和错误修剪的调节——情绪效价和编码水平的影响

前人在项目回忆条件的合作记忆研究中记录到明显的合作抑制和错误修剪,背景提取条件的相关研究尤显不足;同时,情绪效价和编码水平对两类现象调节的研究尚未涉及。为此,本文在两个实验中采用经典合作记忆研究范式,以不同情绪效价的词汇为实验材料并以词汇在学习阶段的呈现颜色为背景展开研究。实验1和实验2分别在学习阶段采用了深编码和浅编码任务,回忆阶段则均含项目回忆(回忆已学词汇)和背景提取(回忆词汇在学习阶段的呈现颜色)两种任务。采用深编码条件的实验1的结果显示,项目回忆比背景提取条件的合作抑制更强、错误修剪更弱,回忆任务与词汇情绪效价交互影响合作抑制强度;采用浅编码条件的实验2则发现错误修剪在两种任务间的差异不显著。两实验的联合分析显示,回忆任务与编码水平交互影响合作抑制和错误修剪强度。上述结果表明:回忆任务对合作抑制和错误修剪的调节支持双重加工模型;回忆任务与情绪效价对合作抑制强度的交互影响支持权衡说,且与双重加工模型相吻合;回忆任务与编码水平交互影响合作抑制和错误修剪强度。     

Ambiguity Attitudes over Time

Previous research demonstrates that individuals exhibit a stronger level of ambiguity aversion for high probabilities than for low probabilities. Given that risky and ambiguous prospects are often unresolved until a future date (e.g., investment decisions, new product launches, and medical interventions), this study examines the impact of time on ambiguity preferences at different probability levels. Our experimental results indicate that although ambiguity preferences for low‐probability events remain constant, a robust effect of time occurs for high‐probability events. More specifically, temporal distance mitigates ambiguity aversion. This effect is consistent for different elicitation methods (preference rating and probability–ambiguity trade‐off tasks). We propose a dual‐process model (affective versus cognitive processing styles) to explain our results. Affective processing for high‐probability lotteries resolved in the current period increases ambiguity aversion, while cognitive processing leads to less ambiguity‐averse choices for future lotteries.

Construal‐level Mindsets Enhance Behavioral Persistence in Response to Incentive Valence

In this research, we find that incentive valence and construal‐level mindsets can interact to influence behavioral persistence on challenging tasks. An abstract mindset improves persistence in response to positively framed incentives whereas a concrete mindset improves persistence in response to negatively framed incentives. This interaction effect can be observed even when the cues inducing construal‐level mindsets are not related to the incentives or the incentivized tasks. Participants in our studies were either positively or negatively incentivized to solve a set of difficult anagrams, and were primed with an abstract or a concrete mindset using spatial (Study 1) and social (Study 2) cues. The participants persisted longer in response to the positively framed incentive when primed with spatially or socially remote cues. In contrast, for the negatively framed incentive, participants persisted longer when primed with spatially or socially proximal cues. Copyright © 2017 John Wiley & Sons, Ltd.     

产后抑郁的预测因素及神经生理机制

产后抑郁是产后时期出现的抑郁症状,对女性及其后代甚至家人都会造成严重的负面影响。产后抑郁稳定的预测因素是遗传基因、依恋风格、童年负性生活经历和激素水平的变化;涉及的脑区和神经网络集中在前额叶皮层、扣带回、杏仁核和海马等脑区及相应神经网络。未来应在探索综合的预测模型、男性伴侣的对照试验和基于大脑可塑性特征的干预模式等方面展开深入研究。     

Stimulus significance effects in habituation of the phasic and tonic orienting reflex

Phasic and tonic measures of electrodermal activity were examined in a simple habituation paradigm, using innocuous visual stimuli. Separate groups were used to investigate the effects of stimulus significance, as manipulated by instructions. One group had no stimulus-related task (indifferent group), while the other was asked to silently count the stimuli to report to the experimenter later (significant group). Prestimulus skin conductance levels were considered as measures of the arousal level at each stimulus presentation, and the subsequent electrodermal responses were taken as the phasic orienting reflex (OR) elicited by each stimulus. Changes in prestimulus arousal were taken as measures of the tonic OR to the experimental series. Marked group differences were found in both phasic and tonic components of the OR. Some, but not all, of the significance effects in the phasic OR were attributable to differences in arousal. The results are discussed in the context of theoretical accounts of the OR.     

Return of fear in a human differential conditioning paradigm caused by a return to the original acquistion context

In a differential human fear conditioning paradigm evidence for ABA-renewal was obtained manipulating the lighting in the experimental room. During acquisition in either a dark or illuminated room, one neutral slide was sometimes paired with a loud aversive noise whereas another slide was not. Subsequently, extinction took place in the opposite lighting context. When afterwards the participants were tested again in the original acquisition context, measurements revealed a recovery of the conditioned electrodermal response and an increase in the retrospective verbal US-expectancy ratings. No response recovery was obtained in an AAA-group that received acquisition, extinction and test trials in one and the same context. Several theoretical explanations for this type of return of fear as well as implications for clinical practice are discussed.
