Simple Discrimination Behavior of Young Chimpanzees: Comparisons with Human Aments and Domestic Animals

The authors' purpose in this paper was to examine how the use of the “sad passive” coping style may be related to adolescent self-reported loneliness. Subjects were asked to complete the revised UCLA Loneliness Scale (Russell, Peplau, & Cutrona, 1980) to determine self-reported loneliness and the Coping with Loneliness Questionnaire (CLQ; Rubenstein & Shaver, 1980) in order to examine coping styles. We hypothesized that those adolescents whose coping strategies fell into the category of sad passivity described by Rubenstein and Shaver would indicate greater loneliness than those adolescents whose coping strategies fell into other categories. Results indicated that sad passivity was used by both lonely and nonlonely adolescents, but that nonlonely youngsters resorted to this method only temporarily and in preparation for a more active coping style. Lonely teens, on the other hand, appeared to remain in the sad-passive mode to a maladaptive degree. These results were discussed in terms of their importance for theories of adolescent loneliness and for possible intervention strategies.     

The Association of Children's Nonverbal Decoding Abilities With Their Popularity,Locus of Control,and Academic Achievement

The present study examined the relation between children's abilities to decode the emotional meanings in facial expressions and tones of voice, and their popularity, locus of control or reinforcement orientation, and academic achievement. Four hundred fifty-six elementary school children were given tests that measured their abilities to decode emotions in facial expressions and tones of voice. Children who were better at decoding nonverbal emotional information in faces and tones of voice were more popular, more likely to be internally controlled, and more likely to have higher academic achievement scores. The results were interpreted as supporting the importance of nonverbal communication in the academic as well as the social realms.     

Personality as a predictor of the objective and subjective impact of sleep deprivation

Although, impairments following sleep deprivation have been clearly demonstrated in the literature, researchers have found a wide range of individual variation in response to sleep deprivation. The relationship between personality and the subjective and objective impact of sleep deprivation was examined using the Epworth Sleepiness Scale, Stanford Sleepiness Scale, Sleep Hygiene Index, Profile of Mood States, an oddball reaction time test, a multi-task cognitive performance battery (SynWin), and the NEO Personality Inventory Revised. Subjects (14 males, 14 females, mean age 20.5) were sleep deprived for 28–35 h and during this time were allowed access to self-reported typical amounts of tobacco, caffeine, and food. Post sleep deprivation: (a) higher neuroticism scores were related to participants feeling sleepier, experiencing more mood disturbance, and performing inferiorly on a behavioral task; (b) subjects scoring as introverts showed more compromised behavioral performance compared to extraverts. The authors suggest that potential moderating variables of the relationship between personality and sleep deprivation such as stimulant use, food intake, and socialization warrant further investigation.     

The relationship between coping style and loneliness in adolescents: can "sad passivity" be adaptive?

The authors' purpose in this paper was to examine how the use of the "sad passive" coping style may be related to adolescent self-reported loneliness.

Spatial and temporal properties of stereoscopic surface interpolation

It is well established that under a wide range of conditions when a sparse collection of texture elements varies smoothly in depth, the spaces between the elements are assigned depth values. This disparity interpolation process has been studied in an effort to define some of its fundamental spatial and temporal constraints. To assess disparity interpolation we employed two tasks: a novel task that relies on the bisection of illusory boundaries created when subjective stereoscopic surfaces intersect, and one that relies on a 3-D shape discrimination. The results of both experiments show that there is no improvement in performance when texture density is increased from near 0.20 to 0.85 or when exposure duration is increased from 50-100 to 1000 ms. This lack of dependence on the addition of features that define the interpolated surface, along with the abrupt decline in performance below a critical value, is consistent with the view that surface interpolation is an important function of human stereoscopic vision.     

Alcohol Reverses Religion's Prosocial Influence on Aggression

The relationship between religion and violence is controversial. Discrepant findings exist between survey studies and the limited number of experimental investigations of religiosity's influence on aggressive behavior. We have attempted to resolve this discrepancy by addressing previous limitations in the literature and assessing a heretofore‐untested moderator of religiosity and aggression: alcohol intoxication. This investigation included a community sample of 251 men and 269 women randomly assigned to either an acute alcohol intoxication condition or a placebo condition. Participants completed a series of questions drawn from standardized instruments of religiosity and spirituality prior to competing on an aggression laboratory paradigm in which electric shocks were received from, and administered to, a fictitious opponent under the guise of a competitive reaction‐time task. Hierarchical regression analyses revealed a significant beverage‐by‐religiosity interaction. Religiosity predicted lower levels of aggression for participants in the placebo group and higher levels of aggression for intoxicated participants. Results indicated that high religiosity coupled with alcohol intoxication may be a risk factor for aggression. This novel finding may help to clarify previous discrepancies in studies of religiosity and aggression.     

The Phenomenology of Hairpulling in College Students

This study examined the phenomenology of hairpulling in a large nonclinical college student sample. Given that hairpulling is conceptualized as occurring on a continuum of severity, we expected to inform the assessment and treatment of Trichotillomania (TTM) by examining hairpulling behavior across its range of presentation. Hairpulling occurred at a rate of 9.7%, while average age of onset was 13.57 years. Self-reported hairpulling styles were identified with 31.3% endorsing focused hairpulling, while 68.7% endorsed an automatic hairpulling style. The most commonly endorsed ritual was “examine the root (37.3%) while the scalp was the most frequently endorsed hairpulling site (49%). Eyelashes were more frequently endorsed as a pulling site by focused (43.8) compared to automatic (5.7%) hairpullers. The hairpulling environments most often endorsed were “while reading” and “while studying” (75%). Affective states were found to change across the pulling cycle in support of hairpulling serving in an emotion regulation capacity. Focused hairpullers endorsed significantly higher trait anxiety than automatic hairpullers. Depression scores (BDI) were elevated for hairpullers compared to non-hairpullers. Implications for assessment and treatment were discussed and directions for future research were provided.     

Cortisol,stress, and attentional bias toward threat

Abstract

Attentional bias toward threatening stimuli is a central characteristic of anxiety and acute stress. Recent small-scale studies have provided divergent perspectives on the association between the stress hormone cortisol and attentional bias toward threat cues. In a larger sample size than previous studies, we examined this association by investigating the impact of cortisol on attentional bias in two studies using a psychological stressor (N=35) and a physical stressor (N=65), respectively. Attentional bias and salivary cortisol were measured prior to and following the administration of a stressful task designed to increase cortisol levels. Results across these studies were equivocal relative to the association between baseline cortisol and baseline attentional bias. In addition, the association between acute change in cortisol and change in attentional bias appeared to differ as a function of the presence or absence of psychological stress. There was a trend toward a stronger negative association between acute cortisol change and attentional bias change among women relative to men. These results imply that the association between cortisol and attentional bias may be moderated by additional factors, such as gender or presence of stress.     

Same-Sex Intimate Partner Violence: Lesbian,Gay, and Bisexual Affirmative Outreach and Advocacy

Intimate partner violence (IPV) is pervasive and crosses all boundaries of sexual orientation, race, and class. Scholars contend that the intimidation of another person through abusive acts and words is not a gender issue. Organizations seeking to offer equitable services to survivors of IPV must intentionally establish themselves as inclusive agencies. This article presents a review of common societal myths and barriers to help-seeking for survivors of same-sex partner violence and offers program guidelines for lesbian, gay, and bisexual affirmative outreach services and advocate training.
