Motivational intensity modulates the effects of positive emotions on set shifting after controlling physiological arousal

Recent research on the construct of emotion suggests the integration of a motivational dimension into the traditional two‐dimension (subjective valence and physiological arousal) model. The motivational intensity of an emotional state should be taken into account while investigating the emotion‐cognition relationship. This study examined how positive emotional states varying in motivational intensity influenced set shifting, after controlling the potential confounding impacts of physiological arousal. In Experiment 1, 155 volunteers performed a set‐shifting task after being randomly assigned to five states: high‐ vs. low‐motivating positive affect (interest vs. serenity), high‐ vs. low‐motivating negative affect (disgust vs. anxiety), and neutral state. Eighty‐five volunteers participated in Experiment 2, which further examined the effects of higher vs. lower degree of interest. Both experiments measured and compared participants' physiological arousal (blood pressure and pulse rate) under the normal and experimental conditions as the covariate. Results showed no difference in switching performance between the neutral and serenity groups. As compared with the neutral state, the high‐motivating positive affect significantly increased set‐switching reaction time costs, but reduced error rate costs; the higher the motivational intensity, the greater the time‐costs impairment. This indicates a role of the high‐motivating positive affect in regulating the balance between the flexible and stable cognitive control. Motivational intensity also modulated the effects of negative emotional states, i.e., disgust caused a larger increase in time costs than anxiety. Further exploration into neurobiological mechanisms that may mediate the emotional effects on set shifting is warranted.

It presents examples of activities appropriate for five levels of social group development. In addition, it provides an example of an activity group protocol directed toward a specific group level. Finally, it includes suggested strategies for activity group leaders in schools, clinics, and hospitals.     

Procesamiento de información en la esquizofrenia: hacia una interpretación alternativa

RESUMEN

En el presente trabajo aceptamos el reto que implica adoptar un pensamiento proposicional y, en consecuencia, presentamos, en primer lugar, evidencia de que los esquizofrénicos parecen tener una ejecución deficiente en multitud de tareas cognitivas que ha sido interpretada en función de un déficit en una fase específica del procesamiento; en la segunda parte, reformulamos tales déficits en términos de lo que para un buen número de investigadores constituye el problema central, esto es, el déficit atencional; a continuación cuestionamos también el propio déficit atencional en favor de un desorden en el arousal para, finalmente, proponer un interpretación de la esquizofrenia a la luz del enfoque de los “Modelos del Actuación en el Mundo”.     

The dynamic relationships of affective synchrony to perceptions of situations

Most theories of affect predict that affects of opposite valence should be negatively correlated (de-synchronous) or independent (asynchronous) within individuals. Such theories were challenged by the finding that the association between energetic arousal and tense arousal ranged from de-synchrony to synchrony (Rafaeli, Rogers, &; Revelle, 2007). In this paper, we report two experience-sampling studies employing cell-phone text-messaging aimed at further exploring individual differences in affective experience. Results showed that within-person relationships between energetic arousal and tense arousal ranged from de-synchrony to synchrony, but that within-person relationships between Pleasant and Unpleasant affect varied from strong de-synchrony to weak de-synchrony. Individual differences in within-person EA-TA associations were related to perceiving threatening situations as incentives and to interactions between affective traits.     

Loss aversion in the eye and in the heart: The autonomic nervous system's responses to losses

The common view in psychology and neuroscience is that losses loom larger than gains, leading to a negativity bias in behavioral responses and Autonomic Nervous System (ANS) activation. However, evidence has accumulated that in decisions under risk and uncertainty individuals often impart similar weights to negative and positive outcomes. We examine the role of the ANS in decisions under uncertainty, and its consistency with the behavioral responses. In three studies, we show that losses lead to heightened autonomic responses, compared to equivalent gains (as indicated by pupil dilation and increased heart rate) even in situations where the average decision maker exhibits no loss aversion. Moreover, in the studied tasks autonomic responses were not associated with risk taking propensities. These results are interpreted by the hypothesis that losses signal the subjective importance of global outcome patterns. Copyright © 2010 John Wiley & Sons, Ltd.     

The desire to win: The effects of competitive arousal on motivation and behavior

The paper theoretically elaborates and empirically investigates the “competitive arousal” model of decision making, which argues that elements of the strategic environment (e.g., head-to-head rivalry and time pressure) can fuel competitive motivations and behavior. Study 1 measures real-time motivations of online auction bidders and finds that the “desire to win” (even when winning is costly and will provide no strategic upside) is heightened when rivalry and time pressure coincide. Study 2 is a field experiment which alters the text of email alerts sent to bidders who have been outbid; the text makes competitive (vs. non-competitive) motivations salient. Making the desire to win salient triggers additional bidding, but only when rivalry and time pressure coincide. Study 3, a laboratory study, demonstrates that the desire to win mediates the effect of rivalry and time pressure on over-bidding.     

Changes in Sexual Functioning and Mood Among Women Treated for Gynecological Cancer Who Receive Group Therapy: A Pilot Study

This study examined changes in sexual functioning and mood disturbance among women who have been treated for gynecological cancer and who participated in a 12-week group intervention for psychosexual problems. The Changes in Sexual Functioning Questionnaire (CSFQ) assessed the sexual functioning, and the Profile of Mood States (POMS) assessed the mood disturbance of 19 women at baseline who completed follow-ups conducted posttreatment and three-month posttreatment. The results showed that the women improved significantly in their CSFQ total scores after being provided with the group therapy intervention at the posttreatment assessment (p < .01), and a statistical trend (p < .10) suggested continued improvement in CSFQ total scores at the three months posttreatment follow-up. Women's POMS total mood disturbance scores improved significantly at the posttreatment assessment (p = .01), but did not show significant improvement at the 3-month posttreatment follow-up. These results suggest that this group intervention achieved its main goal in treating sexual dysfunction as well as mood disturbance, but these improvements dissipated over time and may require further intervention in order to be maintained.     

Men's likelihood of sexual aggression: the influence of alcohol,sexual arousal,and violent pornography

Previous research findings have indicated that both alcohol intoxication and violent pornography exposure may contribute to increased sexual aggression by men. This study used an experimental paradigm to examine the effects of a moderate alcohol dose, alcohol‐related beliefs, and victim response on men's self‐reported likelihood of committing sexual aggression. A community sample of male social drinkers (N=84) participated in an experiment in which they read an eroticized rape depiction after completing an alcohol administration protocol. The stimulus story varied whether the victim, who initially expressed unwillingness to engage in sexual activity, expressed pleasure or distress in response to the man physically forcing her to perform several explicit sex acts. A path analytic model illustrated that participants' self‐reported likelihood of behaving like the sexual aggressor in the story was directly related to their own sexual arousal. Heightened sexual arousal was reported by participants who had consumed alcohol, those who read the victim‐pleasure story, and those who believed that drinking women are sexually vulnerable. Results suggest that sexual arousal to violent pornography, as influenced by acute alcohol intoxication and other factors, may be an important component of men's perceptions of their own sexual aggression likelihood.

The effect of sight levels on daily stressors and coping styles

The structures of daily stressful events of visually impaired people are reported, and the effects of the sight levels of the subjects on these structures are examined. Sixty‐nine visually impaired people (22 males, 47 females) were interviewed and divided into three groups according to their sight levels. Subjects provided examples of stressful events for three coping styles (Don’t, Do by others, Do by oneself). Statistical analyses of the data indicated that the sight levels of visually impaired people are related to the structure of stressful events and coping styles.     

情绪效价、唤醒度和有无评价影响手部动作

研究探讨情绪正-负效价、唤醒度水平(高、中、低)以及有意识评价对推拉动作的影响。分3个实验进行, 收集反应时(RT)和手部动作指标等。实验1使用正-负效价下高、中、低唤醒水平的图片进行评价并执行推-拉动作任务; 实验2使用中性图片和灰色空白图片完成相同任务; 实验3在不进行效价评估情况下完成推-拉动作。结果表明(1)情绪效价对反应时, 运动时间和到达峰速时间等有显著影响：向上拖动图片时, 消极图片拖得更快; 向下拖动时, 则积极图片更快。(2)情绪唤醒度调节情绪效价对推-拉动作的作用：唤醒度越高, 情绪效价尤其是负性情绪对推-拉动作的作用越大; 反之, 则作用越小。(3)无评价条件下, 情绪效价对推-拉动作无显著影响; 即情绪对动作的影响需要有意识评价的参与。这些结果说明情绪对推拉动作影响可能发生在早期, 不仅影响动作计划, 而且影响到随后动作的执行, 而高唤醒度和有意识评价增强了这种影响。
