Gender Differences in Implicit Processing of Sexual Stimuli

The present studies investigated whether men and women differ in cognitive–motivational processing of sexual stimuli in order to better understand the commonly observed gender differences in sexual outcome variables. Because these processes often operate without conscious control, we focused specifically on automatic stimulus processing. Using a series of implicit tasks, we measured inhibition, attentional orientation, appraisal and approach‐avoidance motivation regarding sexually explicit stimuli in male and female students. Results showed that men were more strongly motivated to approach sexual stimuli than women and were better able to inhibit sexual information as to prevent activation of the sexual response. With regard to attentional orientation, men were more easily drawn by sexual cues than women, yet only when the cues were presented long enough to allow more elaborative processing. No gender differences were found in the implicit evaluation of sexual information, although men and women did differ at the level of self‐reported sexual evaluations. Our results indicate the importance of incorporating information‐processing mechanisms and emotion regulation strategies into the conceptualization of the sexual response and promote further research on the specificity, robustness, predictive validity and malleability of the cognitive–motivational processes underlying sexual arousal.

The Effect of Emotion on Visual Attention to Information and Decision Making in the Context of Informed Consent Process for Clinical Trials

The aim of this study was to examine the influence of emotion on visual information processing and decision making in the context of informed consent. Researchers are ethically obligated to ensure informed consent in clinical trials; however, many volunteers have unrealistic expectations about the value of an experimental therapy. Moreover, suboptimal participation rates for clinical trials may be partially attributable to perceptions that ethical obligations to volunteers are not met. This study examines whether discrete negative emotions (fear, anger, and sadness) differentially influence information processing, visual attention, and decisions in the context of clinical trial informed consent. Community participants completed a standard emotion induction (or control) and then read an actual consent form from a clinical trial while eye movements were tracked. Fear and anger produced the most prominently different patterns of systematic processing and visual attention, such that fear induced longer fixations to information presented, whereas anger induced shorter fixations. Moreover, among women only, fear increased decisions to participate, compared with anger and neutral emotion. Examinations of associations between eye‐tracking variables and self‐reported outcomes indicated that for angry participants only, less systematic processing was associated with greater decisions to participate. Negative emotions of any kind decreased accurate perceptions of trial benefit. These patterns suggest a complex interplay among emotion, processing style, and decision making. Future research is necessary to further probe these effects among potential clinical trial volunteers. Published 2016.

Modules in spatial vision: intrinsic reasons of their functional attributes

Visual modules can be viewed as expressions of a marked analytic attitude in the study of vision. In vision psychology, this attitude is accompanied by hypotheses that characterize how visual modules are thought to operate in perceptual processes. Our thesis here is that there are what we call “intrinsic reasons” for the presence of such hypotheses in a vision theory, that is, reasons of a deductive kind, which are imposed by the partiality of the basic terms (input and output) in the definition of a module, and by peculiar characteristics of those terms. Specifically, we discuss three hypotheses of functional attributes: successive stages in the action of modules, residual indeterminacy of their effects, and the role of prior constraints. For each of the three, we indicate its occurrence in perceptual psychology, explain corresponding intrinsic reasons, and illustrate such reasons with examples.     

Performance perceptions and self-focused attention predict post-event processing after a real-life social performance situation

Background and Objectives: Cognitive approaches to social anxiety suggest that an excessive brooding about one's performance in a social situation (post-event processing; PEP) is involved in the maintenance of anxiety. To date, most studies investigating PEP were conducted in laboratory settings. The present study sought to replicate previous findings on predictors of PEP after a naturalistic social performance situation. Methods: Sixty-five students, who had to give an evaluated presentation for credits, completed measures of trait social anxiety. Immediately after their presentation, participants rated state anxiety and attentional focus during the presentation, and provided an overall evaluation of their performance. One week after the presentation, they rated PEP during the preceding week, and reappraised their performance. Results: Regression analyses demonstrated that the performance ratings after and self-focused attention during the presentation were unique predictors of PEP over and above the effects of trait and state anxiety. There was no evidence that PEP was associated with a biased recall of individual performance evaluations. Conclusions: The results support cognitive theories that emphasize the importance of negative self-perceptions in the development of social anxiety and related processes, and underline self-focused attention and self-evaluative processes as important targets during treatment.     

理性-经验加工对不公正情绪和行为反应的影响:公正敏感性的调节作用

基于认知-经验理论,采用行为实验法和情境故事法,探讨了不同信息加工方式对不公正情绪和行为反应的影响,以及受害者敏感性对两者关系的调节作用。结果表明,与理性加工相比,经验加工下个体对不公正有更强烈的负性情绪反应,合作意向更低;受害者敏感性调节加工方式与不公正行为反应之间的关系,即受害者敏感性低时,加工方式与人际公正对合作意向交互作用显著,受害者敏感性高时,加工方式与人际公正对合作意向没有交互作用。     

内外向者幽默加工进程差异:ERP研究

本研究采用事件相关电位技术(ERP),探究幽默的加工进程及内外向者在加工进程中的差异。研究以笑话为实验材料,要求被试先浏览背景信息和妙句结尾,然后评估先后呈现的文字材料的关系。行为结果:内向者的反应时显著短于外向者。ERP结果:(1)幽默加工过程包括不一致探测阶段、不一致消解阶段和情绪加工阶段。(2)不一致无关的N400波幅显著大于一致不可笑;不一致无关的P600波幅显著小于不一致可笑和一致不可笑;800ms之后不一致可笑引发了比一致不可笑和不一致无关更大的正波幅。(3)内外向者在幽默加工进程上的差异主要体现在幽默加工阶段的早期。与内向者相比,外向者在幽默不一致探测阶段所用的认知资源较少,加工的自动化程度较高。     

他人财富情绪:妒忌的社会评估比较与认知加工分析

妒忌是指意识到自己缺乏他人更优越的品质、成就或所有物而产生的自卑、敌意和怨恨等混合情绪,妒忌者渴望得到妒忌目标的优势或希望妒忌目标失去优势。作为一种指向他人财富的复杂情绪,善意妒忌和恶意妒忌会引发不同的行为结果,这主要取决于个体对他人财富的认知评估过程。妒忌通常由向上的社会比较而产生,社会事件应得性、主观公平感、核心自我评价等认知都会对妒忌产生影响。本文从社会比较判断、认知加工过程和神经生理功能等角度来分析妒忌的产生过程和认知机制。基于现有不足,未来的研究可以在妒忌情绪的发展特征、妒忌体验的测量方法和妒忌功能的分化等方面进一步完善。     

Deep processing makes stimuli more preferable over long durations

The purpose of the current study was twofold. First, we investigated whether the type of stimulus processing (e.g. levels of processing) influenced preferences for novel objects. Second, we examined whether the influence of levels of processing on preferences was long lasting (e.g. longer than a day/week). Results showed that levels of processing affected preferences whereby more deeply processed stimuli were preferred over those that were shallowly processed. This effect was more robust for stimuli that were presented multiple times. Additionally, this levels of processing effect lasted for up to 6 weeks, suggesting stability in preferences for information that was more deeply processed. We discuss these results in terms of theories predicting the role of stimulus properties and exposure on the development of preferences.     

Personality change via work: A job demand–control model of Big-five personality changes

Based on the job demand–control model and Gray's biopsychological theory of personality, the author proposed a model to suggest that time demand and job control can drive changes in Big-five personality traits, especially neuroticism and extroversion, by shaping an individual's stress experiences at work. Five waves of data from 1814 employees over a five-year period from the Household, Income and Labor Dynamics in Australia Survey were analyzed. Time demand, job control and job stress were measured in all five waves, and Big-five personality was assessed in the first and last waves. The results showed that time demand and job control shaped job stress positively and negatively at a given time; and over time, an increase in time demand predicted an increase in job stress, which subsequently predicted an increase in neuroticism and a decrease in extroversion and conscientiousness. Results also showed that an increase in job control predicted an increase in agreeableness, conscientiousness, and openness directly, but did not predict change in neuroticism and extroversion. Finally, the buffering effect of job control on the association between time demand and job stress was only observed in two of five waves and such buffering effect was not observed in a change process. The implications on personality development and work design research are discussed.     

On initial item selection in cognitive diagnostic computerized adaptive testing

There has recently been much interest in computerized adaptive testing (CAT) for cognitive diagnosis. While there exist various item selection criteria and different asymptotically optimal designs, these are mostly constructed based on the asymptotic theory assuming the test length goes to infinity. In practice, with limited test lengths, the desired asymptotic optimality may not always apply, and there are few studies in the literature concerning the optimal design of finite items. Related questions, such as how many items we need in order to be able to identify the attribute pattern of an examinee and what types of initial items provide the optimal classification results, are still open. This paper aims to answer these questions by providing non‐asymptotic theory of the optimal selection of initial items in cognitive diagnostic CAT. In particular, for the optimal design, we provide necessary and sufficient conditions for the Q ‐matrix structure of the initial items. The theoretical development is suitable for a general family of cognitive diagnostic models. The results not only provide a guideline for the design of optimal item selection procedures, but also may be applied to guide item bank construction.
