What a feeling! Touching sexually laden stimuli makes women seek rewards

We argue that women's previously documented unresponsiveness to sexual primes when making economic decisions may be a consequence of the specific types of primes that have been used (i.e., visual primes). In three studies we show that presenting women with tactile sexual cues does influence their decisions about economic rewards. Similar to the effect found in men, the first study demonstrates that touching a pair of boxer shorts leads to a craving for monetary rewards in women. In the second study it is shown that touching a pair of boxers makes women less loss averse for both money and food. The third study explicitly focuses on the relative effectiveness of tactile versus visual sexual cues in altering women's economic decisions, and reveals that women's willingness-to-pay for economic rewards increases only when the sexual cue is tactile. We suggest that touching (vs. seeing) sexually laden stimuli prompts pre-programmed consummatory Pavlovian responses that promote approaching economic rewards.     

情绪Stroop效应：威胁驱动还是反应偏差？

为了考查情绪Stroop效应的产生机制是威胁驱动还是反应偏差,本研究进行了两个实验.实验一用一般负性情绪词语和中性词语作为实验材料,实验二用威胁性的情绪图片和中性图片作为实验材料.每个实验均要求一组被试做按键反应,另一组被试做摇杆反应.结果发现,当实验材料为词语时,未出现情绪Stroop效应;当实验材料为威胁性图片时,无论是趋向性反应方式还是回避性反应方式,都出现了情绪Stroop效应.本研究结果支持威胁驱动机制.     

A method in modeling interactive pedestrian crossing and driver yielding decisions during their interactions at intersections

Investigating pedestrian crossing and driver yielding decisions should be an important focus considering the high risks of pedestrians in exposed to motorized traffic. Limitations, however, exist in previous studies – variables considered previously have been limited; how their behavior affect each other (defined as interactive impacts) were not sufficiently considered. This paper aims to provide a methodological approach for pedestrian crossing and driver yielding decisions during their interactions, considering of different variable types including interactive impact variables, traffic condition variables, road design variables, and environment variables. A Distance-Velocity (DV) framework proposed in an earlier study is introduced for definitions and concepts in studying pedestrian-vehicle interactions. Logistic regression, support vector machines, neural networks and random forests, are introduced as candidate models. A case study involving six crosswalk locations is conducted, focusing on interactions between pedestrians and right-turn vehicles. The proposed methodological approach is applied, with the performance of the four machine learning methods compared in terms of model generalization and confusion matrix. The model with the best performance is further compared to the typical gap-based model. Results show that random forest and logistic regression models performed the best in modeling pedestrian crossing and driver yielding decisions respective, in terms of model generalization. Besides, the DV-based modeling method (average accuracy of over 90% for pedestrians and 80% for drivers) outperformed the traditional gap-based method in all test seeds. As a key finding, interactive impacts from each other (the pedestrian and the driver) act as a key contributing variable on their decisions.     

补偿他人还是保护自己?内疚与羞耻情绪对合作行为的影响差异

作为两种常见且易被混淆的自我意识情绪, 诸多研究者对内疚和羞耻的产生前因及影响后效进行研究, 尤其是近年来的研究逐渐关注两者对合作行为的影响。我们通过对已有研究进行梳理发现, 内疚和羞耻对合作行为的影响及其机制存在差异, 内疚的影响更为稳定及具有普适性, 羞耻的影响具有复杂性和多样性, 更容易受到其他因素的影响。内疚和羞耻对合作行为的不同影响可从动机机制和调节机制两方面进行解释。首先, 动机机制包括内疚对他人的补偿、修复动机以及羞耻对自我的保护、修复动机。内疚对他人的补偿、修复动机主要体现在维护社会互动中的公平; 弥补对他人造成的伤害, 降低自己和他人的痛苦; 修复人际关系, 重新获得他人或自己的接纳与认同。羞耻对自我的保护、修复动机主要体现在释放消极的情绪状态; 维护积极的自我形象和声誉, 修复自我; 保护自我, 防止后续伤害及不良后果。总体而言, 内疚者关注过失行为及后果, 侧重于对受害他人的补偿或对与他人关系的修复, 而羞耻者关注整体自我的受损, 侧重于对自我的保护和对自己社会形象的修复, 基于此, 我们在前人研究的基础上构建了内疚与羞耻影响合作行为的动机机制对比模型图。其次, 调节机制涉及到个体因素和情境因素的调节作用, 其中个体因素包括认知因素、社会价值取向、自我控制能力、情绪特质和情绪状态, 情境因素包括暴露情境和掩蔽情境、实验情境和日常情境、相关情境和不相关情境。具体而言, 内疚对合作行为的影响的较少受情境的限制, 而羞耻受情境因素限制较多, 在暴露情境、相关情境中更能促进合作行为的产生, 而在掩蔽情境、不相关情境中, 羞耻较难影响个体的合作抉择, 且无论是实验室情境还是日常情境, 内疚似乎都比羞耻更易影响合作。最后, 鉴于内疚与羞耻的诱发和测量方法的有效性仍需检验, 两种情绪对合作行为影响的过程机制和生理机制仍不明晰, 个体因素影响的研究尚不充足以及跨文化研究较为缺乏, 未来研究可以从内疚和羞耻诱发与测量方法的有效性, 情绪作用发生的内在过程和生理机制, 情绪影响的个体和文化差异这几方面进行扩展和深挖。     

计算机化分类测验终止规则的类别、特点及应用

计算机化分类测验(Computerized Classification Testing, CCT)能够高效地对被试进行分类, 已广泛应用于合格性测验及临床心理学中。作为CCT的重要组成部分, 终止规则决定测验何时停止以及将被试最终划分到何种类别, 因此直接影响测验效率及分类准确率。已有的三大类终止规则(似然比规则、贝叶斯决策理论规则及置信区间规则)的核心思想分别为构造假设检验、设计损失函数和比较置信区间相对位置。同时, 在不同测验情境下, CCT的终止规则发展出不同的具体形式。未来研究可以继续开发贝叶斯规则、考虑多维多类别情境以及结合作答时间和机器学习算法。针对测验实际需求, 三类终止规则在合格性测验上均有应用潜力, 而临床问卷则倾向应用贝叶斯规则。     

Is the hijab protective? An investigation of body image and related constructs among British Muslim women

Previous studies have reported equivocal findings concerning the impact of wearing a hijab, or Islamic head‐ and body‐cover, on Muslim women's body image. Here, we sought to examine that impact using a larger sample of Muslim women than has been relied upon and a wider range of body image measures. A total of 587 British Muslim women completed a battery of scales assessing their frequency and conservativeness of hijab use, body image variables, attitudes towards the media and beauty ideals, importance of appearance, and religiosity. Preliminary results indicated that 218 women never used the hijab and 369 women used some form of the hijab at least rarely. Controlling for religiosity, women who wore the hijab had more positive body image, lower internalization of media messages about beauty standards, and placed less importance on appearance than women who did not wear the hijab. Among women who wore the hijab, hijab use significantly predicted weight discrepancy and body appreciation over and above religiosity. These results are discussed in terms of the possible protective impact among British Muslim women of wearing the hijab.     

Do Religious Affirmations,Religious Commitments,or General Commitments Mitigate the Negative Effects of Exposure to Thin Ideals?

Western pressures for thinness tell women that having a thin body makes a person worthy. Two factors that may provide alternative means of self‐worth are religion and general commitment to a meaningful goal. This study experimentally tested whether religious‐affirming statements buffered against exposure to thin models for everyone, or only for women with strong religious commitment. It also examined the relationships among religious commitment, general commitment, and body satisfaction. One hundred eleven women at a religious‐affiliated college completed the commitment scales and baseline body measures. They were later randomly assigned to read one set of affirming statements, after which they then completed body measures again. Results showed that religious commitment buffered against exposure to ultrathin models. Women who were strongly religiously committed and who read religious statements that affirmed the body showed higher body esteem. Correlation results showed that general commitment was positively related to body esteem, body satisfaction, and healthy dieting. Religious commitment was positively related to body esteem and body satisfaction. Results are discussed in relation to schemas and depth of processing. Practical implications are discussed.     

The Secrecy Heuristic: Inferring Quality from Secrecy in Foreign Policy Contexts

Three experiments demonstrate that in the context of U.S. foreign policy decision making, people infer informational quality from secrecy. In Experiment 1, people weighed secret information more heavily than public information when making recommendations about foreign political candidates. In Experiment 2, people judged information presented in documents ostensibly produced by the Department of State and the National Security Council as being of relatively higher quality when those documents were secret rather than public. Finally, in Experiment 3, people judged a National Security Council document as being of higher quality when presented as a secret document rather than a public document and evaluated others' decisions more favorably when those decisions were based on secret information. Discussion centers on the mediators, moderators, and broader implications of this secrecy heuristic in foreign policy contexts.     

Who’s bringing the donuts: The role of affective patterns in group decision making

Two studies examined how intragroup affective patterns influence groups’ pervasive tendency to ignore the unique expertise of their members. Using a hidden profile task, Study 1 provided evidence that groups with at least one member experiencing positive affect shared more unique information than groups composed entirely of members experiencing neutral affect. This occurred because group members experiencing positive affect were more likely to initiate unique information sharing, as well as information seeking. Study 2 built upon this base by showing that confidence mediates the relationship between positive affect and the initiation of unique information sharing. Additionally, Study 2 investigated the role of negative affect in group decision making and how negative and positive affect concurrently influence decision making when groups are composed of members experiencing each. The results are discussed in terms of the role affect plays in influencing group behavior and the resultant importance of investigating specific affective patterns.     

The vision heuristic: Judging music ensembles by sight alone

Team effectiveness and group performance are often defined by standards set by domain experts. Professional musicians consistently report that sound output is the most important standard for evaluating the quality of group performance in the domain of music. However, across six studies, visual information dominated rapid judgments of group performance. Participants (1062 experts and novices) were able to select the actual winners of live ensemble competitions and distinguish top-ranked orchestras from non-ranked orchestras based on 6-s silent video recordings yet were unable to do so from sound recordings or recordings with both video and sound. These findings suggest that judgments of group performance in the domain of music are driven at least in part by visual cues about group dynamics and leadership.
