Right Hemisphere Positivity Bias in Preconscious Processing: Data From Five Experiments

Using a signal detection paradigm, participants’ sensitivity to emotionally toned stimuli was evaluated in five experiments. A tachistoscope was used to present stimuli to one hemisphere at a time, too rapidly for conscious identification. Pictures, words, and faces were pretested for emotional valence and familiarity. Stimulus selection was based on obtaining the largest possible difference between the positive and negative valence ratings, keeping familiarity equal. Each experiment used a 2×2×2 mixed groups design. The within-subject variables were the hemispheric presentation (right and left) and the emotional tone of the stimuli (positive and negative). Gender of the participant was the between-subjects variable. The results of these studies indicate greater sensitivity in the right than in the left hemisphere, and greater sensitivity to positive than to negative stimuli. Interpretations focus on the automatization of affect and the brain lateralization of emotional processing.     

Age differences in reasons for exercising

We tested the hypothesis that there are age-related differences in reasons for exercising. Adults (n=461), ranging in age from 18 to 86, were asked to indicate if they had considered different types of consequences in their exercise decisions, and how important they thought those consequences were to consider. A three-factor consequence measure examined individuals’ consideration and importance evaluations of various categories of exercise consequences. Results provided mixed support for the hypotheses that younger individuals exhibit greater concern for interpersonal attraction outcomes, while older individuals exhibit greater concern for health outcomes. These results have implications for designing educational and motivational training programs.     

What we want to do versus what we think we should do: an empirical investigation of intrapersonal conflict

People often feel torn between what they want to do and what they believe they should do. As a result, they experience intrapersonal conflict. For example, people know that they should avoid credit card debt, but they want to splurge on just one more purchase. Following Loewenstein's ( 1996 ) temporal perspective to understanding internal conflict and inconsistency, we offer three studies that empirically demonstrate (1) a distinction between the want self and the should self, (2) that behavior is more closely linked to the want self, (3) that the want self is the self that is temporally inconsistent, and (4) that adopting a want versus should perspective can have a significant impact on actual behavior.

Theobiology: An Analysis of Spirituality, Cardiovascular Responses, Stress, Mood, and Physical Health

The relationships of spirituality and religion to acute cardiovascular responses, physical symptoms of illness, stress and psychological mood were assessed in a community sample of adults. Nineteen men and 61 women participated in a betrayal interview, while their blood pressure and heart rate were monitored. Religious affiliation, frequency of attendance at worship and religiousness were associated with resting diastolic and mean arterial pressure. Spirituality, especially as assessed by the existential scale of the Spiritual Well-being Scale, was related to symptoms of illness, medication use, stress and negative mood states. Spirituality and involvement in organized religion may represent a means to increase the sense of purpose and meaning in life, which is related to greater resiliency and resistance to stress-related illness.     

Predicting self‐esteem during unemployment: The effect of gender,financial deprivation,alternate roles,and social support

Two hundred and one unemployed men and women participated in a cross‐sectional study that assessed self‐esteem, financial deprivation, number of alternate roles, and use of social support. Financial deprivation, alternate roles, and social support each had a main effect on self‐esteem. In addition, these variables interacted with gender to affect self‐esteem. Specifically, financial deprivation had a greater negative association with self‐esteem in men as compared with women. In contrast, alternate roles and social support had a stronger positive relationship to self‐esteem in women than in men. The incorporation of these findings into intervention programs for unemployed persons is discussed.     

Menstrual cycle, beta-endorphins, and pain sensitivity in premenstrual dysphoric disorder.

This study examined pain sensitivity and pain modularity mechanisms (e.g., beta-endorphin levels, blood pressure) in women with premenstrual dysphoric disorder (PMDD; n = 27) and healthy controls (n = 27) during the follicular and luteal phases of the menstrual cycle. Physiological measures were taken during rest and ischemic pain testing. In both cycle phases, PMDD women (a) displayed lower resting cortisol and beta-endorphin levels and (b) exhibited shorter pain threshold and tolerance times and greater pain unpleasantness ratings during pain. PMDD women also reported greater pain unpleasantness and intensity and had lower beta-endorphin levels in their luteal phase and tended to display higher blood pressure levels at rest and during pain testing. Results suggest that endogenous opioids may be pathophysiologically relevant to PMDD and that the hypothalamic-pituitary-gonadal axis may modulate pain sensitivity in PMDD.     

We think you agree: The detrimental impact of the false consensus effect on behavior

Two studies were designed to examine the impact of the false consensus effect on behavior (FCE; Ross, Greene, & House, 1977). False consensus is a form of social projection whereby individuals overestimate the degree to which others share their characteristics or beliefs. In a modified test of the theory of reasoned action, Study 1 demonstrated that the FCE independently predicts behavioral intentions regarding important social issues in a sample comprised of 205 college students. Further, results indicated that self-monitoring moderates the extent to which the FCE predicts behavioral intentions (specifically, as hypothesized, the FCE is a stronger predictor of behavior for high self-monitors). Because of the prevalence of the FCE among college students regarding potentially harmful social behaviors, Study 2 was designed to eliminate the FCE by differentially presenting students (N = 280) with alternative viewpoints regarding various issues. Presenting both sides of an argument using video-based stimuli effectively reduced the FCE. Recommendations for interventions that effectively promote beneficial social norms are discussed.     

Can empathy close the racial divide and gender gap in death penalty support?

Public opinion data indicate that the majority of US respondents support the death penalty. Research has consistently indicated, however, that Blacks and females are significantly less likely to support capital punishment than their White and male counterparts. Past research efforts attempting to account for these differences have, at best, only partially accounted for them: the racial divide and gender gap in death penalty support, while narrowed, remained evident. This study proposes that empathy, particularly ethnocultural empathy, may be a key explanatory correlate of death penalty support and that racial and gender differences in empathy may fully explain the observed racial and gender differences in death penalty support. This study uses three forms of empathy measures (cognitive, affective, and ethnocultural) to test this hypothesis using survey data from a sample of undergraduate students. Our results show that neither a variety of other “known correlates” of death penalty support nor cognitive or affective empathy scales were able to fully account for the observed racial difference in death penalty support. Ethnocultural empathy, however, was successful in reducing the effect of race on death penalty support to nonsignificance. To the best of our knowledge, this is the first study to have done so.
