Resting EEG in alpha and beta bands predicts individual differences in attentional blink magnitude

Accuracy for a second target (T2) is reduced when it is presented within 500 ms of a first target (T1) in a rapid serial visual presentation (RSVP) - an attentional blink (AB). There are reliable individual differences in the magnitude of the AB. Recent evidence has shown that the attentional approach that an individual typically adopts during a task or in anticipation of a task, as indicated by various measures, predicts individual differences in the AB deficit. It has yet to be observed whether indices of attentional approach when not engaged in a goal-directed task are also relevant to individual differences in the AB. The current studies investigated individual differences in the AB by examining their relationship with attention at rest using quantitative measures of EEG. Greater levels of alpha at rest were associated with larger AB magnitudes, where greater levels of beta at rest were associated with smaller AB magnitudes. Furthermore, individuals with more beta than alpha demonstrated a smaller AB effect than individuals with more alpha than beta. Our results suggest that greater attentional engagement at rest, when not engaged in a goal-directed task, is associated with smaller AB magnitudes.     

儿童期情感忽视对大学生抑郁的影响:控制感与情绪调节自我效能感的链式中介作用

为探讨儿童期情感忽视与大学生抑郁的关系,以及控制感和情绪调节自我效能感在其中的中介作用,采用儿童期创伤问卷、控制感量表、情绪调节自我效能感量表和贝克抑郁量表(第2版),对重庆市两所高校共837名大学生进行调查。结果显示:(1)儿童期情感忽视显著正向预测大学生抑郁;(2)控制感、情绪调节自我效能感在儿童期情感忽视与抑郁之间起独立中介作用;(3)控制感与情绪调节自我效能感在儿童期情感忽视与抑郁之间起链式中介作用,且情绪调节自我效能感各维度的效应皆成立。本研究考察了儿童期情感忽视对抑郁的影响及其作用机制,为家庭教养方式的改善及大学生抑郁问题的预防与干预提供了实践启示。     

样例呈现方式对概念训练类别表征的影响

以往研究发现训练形式会影响类别学习的表征方式。实验采用学习-迁移范式,探究概念训练中样例的呈现方式对类别表征的影响。实验中被试通过不同呈现方式来学习类别知识,在学习3个block之后对其进行测验。实验结果表明:(1)学习单样例和同一类别比较学习的被试在测验阶段的成绩与学习阶段之间没有差异;(2)学习不同类别比较学习的被试在测验阶段的成绩大幅度下降。因此得出结论,在概念训练中,不同类别比较学习导致被试形成类别间信息的表征。     

The effect of cultural values on pro-environmental attitude in the context of travel mode choice: A hierarchical approach

The cultural theory explains social behavior through four elementary types of cultural values consisting of hierarchy, individualism, egalitarianism, and fatalism. The knowledge of how these values influence attitudes and behaviors specifically pertain to the environment is limited. Understanding individuals’ values and attitudes should be addressed in travel mode choice based on possible impacts of transportation on the environment. This study investigates the effect of cultural values on pro-environmental attitude and the influence of this attitude on travel mode choice in light of a hierarchical latent choice model. The model is estimated using data from a random sampling in CBD (Central Business District) of Tehran, Iran. The pro-environmental attitude, which is postulated to be affected by cultural values, is considered as the latent variable directly affecting travel mode choice. The cultural values drivers of pro-environmental attitude have been seen in a hierarchical structure. The estimated results show that hierarchical cultural tendency has the strongest and positive effect on being pro-environmental. Also, individualistic culture indicates a positive trend in being pro-environmental. On the other side, people with egalitarianism value tend to report an orientation towards pro-environmental attitude. Moreover, pro-environmental attitude increases the utility of public and active modes of transportation and a negative significant effect is found on the utility of private car and motorcycle.     

反刍思维的脑功能网络机制

反刍思维是指个体在经历了消极生活事件后不由自主地反复思考该事件的产生原因、经过和结果, 表现出负性自我参照加工、消极情绪性以及持续性的特点。采用脑功能网络分析方法, 研究者发现反刍思维的上述三个特点分别与默认网络内部的异常活动模式、突显网络功能连接的改变以及注意相关网络之间的异常耦合有关。未来研究应进一步明确反刍思维与相关脑网络活动之间的因果关系, 探究反刍思维脑功能网络的结构基础, 同时也应关注反刍思维及其脑网络的老龄化特征, 并致力于探索有效干预反刍思维的神经调控技术。     

媒体多任务经验对不同注意模式下内隐记忆的影响

本研究采用经典背景线索范式,在分布式注意（限制眼动）和集中式注意（自由观看）两种模式下考察不同媒体多任务经验者的内隐记忆表现。实验1要求被试在学习阶段自由观看场景并搜索目标,在测试阶段限制眼动并使用外周视野搜索目标。实验2将学习、测试阶段的注意模式反转。结果发现,高媒体多任务经验者在两种注意模式下均表现出背景线索效应;低媒体多任务经验者仅在集中式注意模式下表现出背景线索效应。结果表明,高媒体多任务经验者在分布式注意模式下存在一定的内隐记忆优势。     

Self‐regulation predicts risk‐taking through people's time horizon

In the context of decision‐making research, people's regulatory orientation mode (i.e., assessment and locomotion modes) has been included among the most prominent individual difference variables, which may potentially account for choice behaviour. Thus, the main objective of our experiment was to investigate the relations between habitual use of regulatory mode and risk‐taking through people's time horizon. Risk‐taking was appraised using a behavioural measure (i.e., BART) 1 month following evaluation of habitual use of regulatory mode. The findings revealed a significant negative association between the assessment mode and risk‐taking through individual differences in time horizon.     

Neural correlates of viewing paintings: Evidence from a quantitative meta-analysis of functional magnetic resonance imaging data

Many studies involving functional magnetic resonance imaging (fMRI) have exposed participants to paintings under varying task demands. To isolate neural systems that are activated reliably across fMRI studies in response to viewing paintings regardless of variation in task demands, a quantitative meta-analysis of fifteen experiments using the activation likelihood estimation (ALE) method was conducted. As predicted, viewing paintings was correlated with activation in a distributed system including the occipital lobes, temporal lobe structures in the ventral stream involved in object (fusiform gyrus) and scene (parahippocampal gyrus) perception, and the anterior insula—a key structure in experience of emotion. In addition, we also observed activation in the posterior cingulate cortex bilaterally—part of the brain’s default network. These results suggest that viewing paintings engages not only systems involved in visual representation and object recognition, but also structures underlying emotions and internalized cognitions.     

Asymmetric Perception of Gains versus Non‐losses and Losses versus Non‐gains: The Causal Role of Regulatory Focus

Recent studies show that, while losses loom larger than equivalent non‐gains, gains loom larger than equivalent non‐losses. This finding has been interpreted within the framework of regulatory focus theory. In this study, we highlight the importance of considering the motivational focus independently of the framing and the valence of outcome, thus exploring the causal effect of regulatory focus on the asymmetric perception of gains versus non‐losses and losses versus non‐gains. In two studies, we examine the perceived effects of either actual or hypothetical changes in monetary wealth, while orthogonally manipulating framing, valence, and regulatory focus. We find a significant interaction between the three factors. The gain versus non‐loss asymmetry in perceived satisfaction is stronger in promotion focus, whereas the loss versus non‐gain asymmetry in perceived dissatisfaction is stronger in prevention focus. The results suggest that the effects of incentives framed in terms of (non)gains and (non)losses depend on their congruence with the individual's motivational state.
