Individual differences in cardiovascular reactions to stress and cigarette smoking

The present study examined the stability of cardiovascular reactions to psychological stress and cigarette smoking, and the extent to which cardiovascular reactions to stress were predictive of cardiovascular reactions to smoking. Thirty subjects were given an initial test involving two repetitions of mental arithmetic stress and paced smoking while blood pressure and heart rate were measured. Two months later, 26 of these subjects were retested in the same paradigm. Large and stable individual differences were observed in cardiovascular reactivity to both stress and smoking. Moreover, for systolic and diastolic blood pressure, but not heart rate, reactions to stress were modestly correlated with reactions to cigarette smoking. These results are consistent with the possibility that level of reactivity to cigarette smoking may constitute a risk factor for coronary heart disease, and that one or more common variables may mediate the magnitude of blood pressure reactivity to both stress and cigarette smoking.     

Subjective well-being in urban adolescents of color

Relationships among predictors and criteria of subjective well-being were examined in a sample of 151 urban adolescents of color, ages 12-15. The relative strengths of family, peer, and school-related support and esteem in predicting three measures of subjective well-being (life satisfaction, positive affect, and negative affect) were explored. Results suggested that sense of worth in one's family explained a significant amount of variance in subjective well-being variables, above and beyond the contributions of individual, school, and peer-related variables. Implications for prevention and mental health promotion with urban adolescents of color are discussed based on these findings.     

Regulatory foci and organizational commitment

We use regulatory focus theory to derive specific predictions regarding the differential relationships between regulatory focus and commitment. We estimated a structural equation model using a sample of 520 private and public sector employees and found in line with our hypotheses that (a) promotion focus related more strongly to affective commitment than prevention focus, (b) prevention focus related more strongly to continuance commitment than promotion focus, (c) promotion and prevention focus had equally strong effects on normative commitment. Implications of these findings for the three-component model of commitment, especially the ‘dual nature’ of normative commitment, as well as implications for human resources management and leadership are discussed.     

Unravelling the riddle of exhibitionism: a lesson in the power tactics of perverse interpersonal relationships

Through an examination of the varied paradoxes embedded within the phenomenon of genital exhibitionism, the author establishes exhibitionism as a paradigm for interpersonal relations whereby one individual entices another to lose himself, to a benign or dangerous degree, in a presented portrayal/enactment. Efforts to entice that cause an extreme loss of the subject's sense of self--making it exceedingly hard to break free of--are designed to render the subject powerless and take psychic possession of him. The perpetrator accomplishes this feat by interacting with his victim in ways capable of producing a sudden and profound regression with sufficient loss of autonomous ego functioning that the subject finds it hard, if not impossible, to act on his own behalf. The essential feature of the perpetrator's efforts is his violation of the unspoken but understood rules of interpersonal engagement that, when violated, cause extreme disorientation and a loss of trust in one's most basic assumptions about how humans treat one another. When this happens, we would describe the interaction as having been perverted to serve the exclusive needs of the predator--to gain as complete control over the other as possible.     

Psychological trauma and schizotypal personality disorder

Two studies examined the relation between psychological trauma and schizotypal symptoms. In Study 1, in which 1,510 adults completed telephone interviews, both childhood maltreatment and the experience of an injury or life-threatening event were significantly associated with schizotypal symptoms. In Study 2, in which 303 adults (oversampled for having elevated levels of schizotypal symptoms) completed extensive in-person assessments, both childhood maltreatment and meeting posttraumatic stress disorder (PTSD) Criterion A were significantly associated with schizotypal symptoms. The links between schizotypal symptoms and at least some forms of psychological trauma could not be fully accounted for by shared variance with antisocial and borderline personality disorders, absorption/dissociation, PTSD symptom severity, family history of psychotic disorder, or signs of neurodevelopmental disturbance (as indexed by minor physical anomalies and inconsistent hand use). Schizotypal symptoms were more strongly associated with childhood maltreatment among men than among women, whereas schizotypal symptoms were more strongly associated with PTSD Criterion A among women than among men. Finally, among men, the association between childhood maltreatment and schizotypal symptoms was moderated by signs of neurodevelopmental disturbance.     

Evidence for positive mood buffering among college student drinkers

Positive experiences play an important role in buffering the effects of negative experiences. Although this process can play out in a myriad of contexts, the college context is one of particular importance because of significant concerns about student stress levels and alcohol abuse. Building on evidence that at least some students drink in response to negative experiences, we considered the possibility that positive moods would moderate college student negative mood-drinking relationships. Using a Web-based daily process study of 118 (57% women) undergraduate student drinkers, the authors reveal that positive moods indeed buffer the effects of negative moods on student drinking, depending on the mood and drinking context. Furthermore, the buffering of ashamed mood appears to explain the buffering of other negative moods. Implications of these findings are considered in terms of the relationship between negative self-awareness and drinking to cope.     

The influence of dominant versus non-dominant hand on event and emergent motor timing

It has been hypothesized that timing in tapping utilizes event timing; a clock-like process, whereas timing in circle drawing is emergent. Three experiments examined timing in tapping and circle drawing by the dominant and non-dominant hand. Participants were right-hand dominant college aged males and females. The relationship between variance and the square of the timed interval (the Weber fraction), thought to capture clock-like timekeeping processes, was compared. Furthermore, timing variance was decomposed into a clock and a motor component. The slopes for timing were different for dominant hand tapping and circle drawing, but equal for non-dominant and dominant hand tapping. Negative lag one covariance, consistent with motor implementation variability, was found for non-dominant but not for dominant hand circle drawing (Experiment 1). Practice did not influence this relation (Experiment 2). A significant correlation for clock variability was found between non-dominant hand circle drawing and tapping (Experiment 3). Collectively, these findings indicate that event timing is shareable across hands while emergent timing is specific to an effector. Emergent timing does not appear to be obligatory for the non-dominant hand in circle drawing. We suggest that the use of emergent timing might depend upon the extensive practice experienced by a person's dominant hand.     

Predicting Outcomes or Modeling Process? Commentary on the Health Action Process Approach

Schwarzer (2008 ) reviews the evidence for two major contributions of the Health Action Process Approach model (HAPA) to current theory and behavioral health research: (1) the differentiation of concepts by both content and process, and (2) clear recognition of the temporal aspect in the assembly of health behavior sequences. This commentary discusses four areas for HAPA to address for a more complete explanation of health behaviors and their determinants. Further, we suggest that incorporating into HAPA the hierarchical structure of the control systems that regulate health behaviors and the importance of concrete experience in initiating and maintaining behavior, elements emphasised in the Commonsense Model of Self‐regulation, will enrich HAPA's theoretical base and increase its utility for the development of interventions for behavioral change. Schwarzer (2008 ) examine les données confirmant deux contributions majeures du modèle de l’Approche du Processus de l’Action en faveur de la Santé (HAPA) à la théorie et aux recherches sur les comportements relatifs à la santé: 1) La différenciation des concepts à la fois par le contenu et le processus, 2) Un repérage précis de la dimension temporelle dans l’articulation des séquences comportementales relevant de la santé. Ce commentaire aborde quatre points qui permettraient à l’HAPA de fournir une explication plus complète des conduites liées à la santé et de leurs antécédents. Il semble en outre que l’introduction dans l’HAPA de la structure hiérarchique des systèmes de contrôle qui régulent les comportements de santé et de l’aspect important qu’est l’expérience concrète dans l’amorce et le maintien du comportement, éléments mis en valeur par le Modèle du Sens Commun de l’Autorégulation, enrichirait les fondements théoriques de l’HAPA et augmenterait son utilité pour l’élaboration d’interventions en faveur du changement comportemental.     

Organizational identification and organizational commitment: Distinct aspects of two related concepts

The conceptual differences between organizational commitment and identification are discussed theoretically and examined empirically. The present study is based on data of 450 employees of five different organizations in Nepal. A revised eight-item scale was designed out of Cheney's Organizational Identification Questionnaire to assess the core aspects of organizational identification. In confirmatory factor analyses, identification was found to be distinguishable from four related commitment concepts (i.e. affective, continuance, normative, and attitudinal commitment).     

Substance use patterns of young offenders and violent crime

The use of alcohol is a significant predictor of the involvement of young offenders in violent crime. This study found that in a sample of 300 incarcerated juveniles in New South Wales, more than 70% admitted to violent crime. Detainees from an Aboriginal or Torres Strait Islander culture were less likely than other detainees to be involved in violent crime. The substances most associated with violent crime were alcohol, followed by cocaine. However, when the likelihood that the young person has initiated violence as a response to alcohol or other substances is introduced into the equation, the direct effects for alcohol and cocaine predicting engagement in violent crime disappear. The Goldstein hypothesis that the effects of a substance directly facilitate violence, thereby accounting for the relationship between substances of use and violent crime, was supported. Aggr.
