Implicit power motive effects on the ERP processing of emotional intensity in anger faces

Research has shown that anger faces represent a potent motivational incentive for individuals with high implicit power motive (nPower). However, it is well known that anger expressions can vary in intensity, ranging from mild anger to rage. To examine nPower-relevant emotional intensity processing in anger faces, an ERP oddball task with facial stimuli was utilized, with neutral expressions as the standard and targets varying on anger intensity (50%, 100%, or 150% emotive). Thirty-one college students participated in the experiment (15 low and 16 high nPower persons determined by the Picture Story Exercise, PSE). In comparison with low nPower persons, higher percentage of correct responses was observed for high nPower persons when both groups discriminated low-intensity (50% intensity) anger faces from neutral faces. ERPs between 100% and 150% anger expressions revealed that high-intensity (150%) anger expressions elicited larger P3a and late positive potential (LPP) amplitudes relative to prototypical (100% intensity) anger expressions for power-motivated individuals. Conversely, low nPower participants showed no differences at both P3a and LPP components. These findings demonstrate that persons with high nPower are sensitive to intensity changes in anger faces and their sensitivity increases with the intensity of anger faces.     

Effects of product type and contextual cues on eliciting naive theories of popularity and exclusivity

This research shows in a series of studies that exposing consumers to functional products evokes the naive theory of popularity, whereas exposing them to self-expressive products induces belief in the naive theory of exclusivity. The research further demonstrates that when the naive theory elicited by product type is matched by the appropriate contextual purchasing cues regarding the interest of others, it results in greater purchase intentions than when those cues are mismatched. The research specifies that the matching effect for functional products is mediated by consumers' perceptions of product quality, whereas mediation for self-expressive products occurs through consumers' self-perceptions regarding the extent to which the product conveys uniqueness. Finally, the research illustrates that an explicit signal of product quality (e.g., a favorable rating in Consumer Reports) attenuates the effect associated with the contextual cues regarding the interest of others.     

Computer-based written emotional disclosure: the effects of advance or real-time guidance and moderation by Big 5 personality traits

Standard written emotional disclosure (WED) about stress, which is private and unguided, yields small health benefits. The effect of providing individualized guidance to writers may enhance WED, but has not been tested. This trial of computer-based WED compared two novel therapist-guided forms of WED – advance guidance (before sessions) and real-time guidance (during sessions, through instant messaging) – to both standard WED and control writing; it also tested Big 5 personality traits as moderators of guided WED. Young adult participants (n = 163) with unresolved stressful experiences were randomized to conditions, had three, 30-min computer-based writing sessions, and were reassessed six weeks later. Contrary to hypotheses, real-time guidance WED had poorer outcomes than the other conditions on several measures, and advance guidance WED also showed some poorer outcomes. Moderator analyses revealed that participants with low baseline agreeableness, low extraversion, or high conscientiousness had relatively poor responses to guidance. We conclude that providing guidance for WED, especially in real-time, may interfere with emotional processing of unresolved stress, particularly for people whose personalities have poor fit with this interactive form of WED.     

Bomb threats and offender characteristics in Japan

This study examined telephone bomb threats and offender characteristics in Japan (N = 101). The results showed that the most frequent offenders were middle‐aged men (mean 42.6 years), motivated by desire for money (46%), resentment (26%), or diversion (24%). In the case of female offenders, most were connected with the targets (83%). Categorical principle component analysis and hierarchical cluster analysis differentiated the offenders into three themes. ‘Instrumental’ offenders telephoned the target directly (e.g. a bank or department store), demanding money by public phone. ‘Expressive/affective’ offenders motivated by resentment telephoned from their home and almost never had a criminal record. ‘Expressive/cognitive’ offenders motivated by diversion targeted railways and mostly telephoned emergency numbers.

“I want to pray and I don’t want to pray”: expressive individualism and prayer

This article reports on a study of the relationship between expressive individualism, an important characteristic of individualistic cultures, and different varieties of prayer. Four dimensions of expressive individualism (autonomy, setting oneself apart from others, personal development, and the expression of emotions) and four types of prayer (petitionary, religious, meditative, and psychological) were distinguished. Data were collected from participants in internet forums on Christian religiosity (N?=?158); they were asked to complete questionnaires about expressive individualism and prayer. The relationship between expressive individualism and prayer was found to be an ambivalent one, and one that is negatively dominated by autonomy. After eliminating the effect of autonomy, two patterns remain visible, both of them characterised by a positive connection to religiosity. Setting oneself apart from others is associated with petitionary and religious prayer; personal development with meditative and psychological prayer. The explanation of this concealed longing for religion is sought in the pressure resulting from expressive individualism as a way of life.     

Disentangling the effects of choice and intensity on affective response to and preference for self-selected- versus imposed-intensity physical activity

ObjectiveTo examine the independent effects of physical activity (PA) intensity and choice of PA intensity when comparing affective response to and relative preference for self-selected-intensity versus imposed higher intensity PA.DesignWithin-subjects experiment.MethodsTwenty-nine healthy, low-active women completed four PA bouts over two sessions. The first session consisted of a one-third mile self-selected-intensity treadmill walk during which the speed was recorded, but was not visible to the participants. The second session consisted of three, counterbalanced, one-third mile treadmill conditions: (a) self-selected intensity, (b) same intensity as recorded for the first-session-self-selected-intensity walk, but with the intensity imposed by the experimenter (i.e., yoked-self-selected intensity), and (c) intensity set at 20% higher than the first-session-self-selected-intensity walk (imposed higher intensity). Acute affective valence (pleasure/displeasure) was recorded prior to, during, and following each walking bout. Preference for each walking intensity was assessed using a behavioral-choice paradigm.ResultsContrary to hypotheses, there was no effect of condition on acute affective valence. However, consistent with hypotheses, there was a linear trend, F(1, 22) = 11.00, p = .003, indicating preference in descending order from self-selected-intensity to yoked-self-selected-intensity to imposed higher intensity PA.ConclusionsBoth choice over the intensity and a lower intensity per se contributed to greater preference for self-selected-intensity over imposed higher intensity PA among healthy low-active women; however, there was no evidence to support the notion that affective response to PA mediated this relationship.     

Pleasure and interest are differentially affected by replaying versus analyzing a happy life moment

Previous research regarding the effects of thinking about a happy moment on emotional experience has been equivocal. The discrepancies may be explained by different modes of thinking: systematically thinking about a happy moment versus mentally replaying the happy moment. Another explanation may involve the difference between the emotion of interest and the emotion of pleasantness, which are often erroneously grouped together under the broad concept of ‘positive affect.’ We hypothesized that systematically thinking about a happy moment would generate interest, whereas mental replaying would generate pleasantness. In an experimental setting, people who systematically analyzed a happy moment increased feelings of interest, while the level of pleasantness remained unchanged. In the alternative condition, people who mentally replayed a happy moment reported increased interest and pleasantness. At post-intervention, the replay group scored higher on pleasantness, but not on interest, relative to the analyze group.     

The moderating effects of gender on the associations between multidimensional hostility and psychosomatic symptoms: a Chinese case

The purpose of this study was to examine the effects of gender on the relationship between multidimensional hostility and psychosomatic symptoms in Chinese culture. The participants in this study were 398 Chinese college students (40% female) recruited from Taiwan. Four dimensions of multidimensional hostility-hostility cognition, hostility affect, expressive hostility behavior, and suppressive hostility behavior-were measured by the Chinese Hostility Inventory. After controlling for the effects of depression and anxiety, the results of path analysis revealed that the multidimensional hostility predicted psychosomatic symptoms directly, and predicted psychosomatic symptoms indirectly through negative health behavior. Furthermore, gender moderated the relationships between multidimensional hostility and health outcomes. Expressive hostility exacerbated psychosomatic symptom in females but buffered it in males, while affective hostility exacerbated psychosomatic symptoms in males. Additionally, suppressive hostility behavior was correlated to psychosomatic symptoms indirectly through negative health behavior in females. Moreover, expressive hostility was correlated to psychosomatic symptoms indirectly through negative health behavior more in males than in females.
