Impulsivity, fight history, and camaraderie as predictors of a willingness to escalate a disturbance

This field study examined the relationships between six predictor variables and a self-report measure of spectators' likelihood of joining in a crowd disturbance. Subjects were males (N = 78) found in attendance at an ice hockey game. The variables jects were males (N = 78) found in attendance at an ice hockey game. The variables related to the likelihood of escalating a disturbance included subjects who were more impulsive, had a history of fighting, were younger, saw provocations as more volatile, liked to watch player fights and attended with others. A multiple regression analysis yielded a solution that accounted for 52.9% of the variance. The results were discussed against the background of previous research examining the factors associated with spectators' propensity for involving themselves in crowd disorders.

Antiunion and prounion attitudes as predictors of college students' willingness to join a union

The authors proposed a model of antiunion attitudes and prounion attitudes as predictors of American college students' willingness to join a union (N = 1,245). Structural equation modeling results indicated that antiunion and prounion attitudes are moderately related and both show similar strength in predicting willingness to join. In addition, a general antiunion factor is shown to underlie specific antiunion attitudes, whereas items related to prounion attitudes are shown to reflect a general prounion factor. The utility of the model was supported based on initial and cross-validation samples (ns = 623 and 622, respectively). Implications for measuring union attitudes and recruiting union members among college-educated workers are discussed.     

Social representations of history,cultural values,and willingness to fight in a war: A collective‐level analysis in 40 nations

This study explores at the national level beliefs about world history and their relationship with cultural values and attitudes towards a national war. A country‐level analysis of university samples from 40 nations involving 7279 students showed that beliefs about history as a superior plan, as social progress, and lawful processes were positively associated with lower human development, and materialistic and power distance values, as well as with willingness to fight in a future national war. Further, beliefs about history as a superior plan, as social progress, and as lawful process were positively related with a stronger disposition to fight, even after controlling for cultural values and human development. Results are discussed in the framework of conceptualizing social representations of history as part of national political cultures.     

Anxiety sensitivity and history of panic as predictors of response to hyperventilation

In this study, we examined the effects of anxiety sensitivity on the response to hyperventilation in college students with and without a history of spontaneous panic attacks. Reiss et al.'s (Behav. Res. Ther. 24, 1-8, 1986) Anxiety Sensitivity Index and Norton et al.'s (Behav. Ther. 17, 239-252, 1986) Panic Attack Questionnaire were used to select Ss. Following five min of voluntary hyperventilation, high anxiety sensitivity Ss reported more anxiety and more hyperventilation sensations than did low anxiety sensitivity Ss. A history of panic was only associated with enhanced responding to hyperventilation in Ss with high anxiety sensitivity; low anxiety sensitivity Ss who had experience with panic were no more responsive than low anxiety sensitivity Ss who had never had a panic attack. These findings suggest that high anxiety sensitivity may be a crucial determinant of panic attacks provoked by biological challenges (e.g. hyperventilation, sodium lactate infusion).     

Impulsivity,sensation seeking and reproductive behaviour: A life history perspective

Impulsivity has often been invoked as a proximate driver of different life-history strategies. However, conceptualisations of “impulsivity” are inconsistent and ambiguities exist regarding which facets of impulsivity are actually involved in the canalisation of reproductive strategies. Two variables commonly used to represent impulsivity were examined in relation to reproductive behaviour. Results demonstrated that sensation seeking was significantly related to strategy-based behaviour, but impulsivity (defined as a failure to deliberate) was only weakly correlated. The effect of impulsivity disappeared when sensation seeking was controlled. Sex differences emerged for sensation seeking but not impulsivity. We conclude that “impulsivity” is not a unitary trait and that clearer distinctions should be made between facets of this construct.     

Impulsivity as a predictor of smoking and alcohol consumption

This prospective study examined the relationships between impulsivity, smoking and alcohol use in a large non-clinical sample of 601 men and 4832 women working in 12 Finnish hospitals. Data on impulsivity, smoking and alcohol consumption were collected by two questionnaires with a two-year interval. At baseline, impulsivity was associated with smoking and alcohol use. After controlling for baseline smoking, impulsivity predicted increased number of cigarettes smoked per day in women (p=0.08), but not in men. After controlling for alcohol use at baseline, impulsivity predicted increased alcohol consumption similarly in both genders (p<0.01). Higher impulsivity was also associated with increased likelihood of taking up smoking or becoming a heavy drinker (p<0.05). This evidence suggests that impulsivity contributes to increasing health risk behaviours.     

Sociotropy-dependency and autonomy as predictors of eating disturbance among Canadian female college students

The authors (a) tested the generalizability of A. Sugarman, D. Quinlan, and L. Devenis's (1982) psychodynamic account of eating disturbances, which posits that overt autonomy strivings associated with eating problems are a defense against unconscious dependency concerns, and (b) evaluated the degree to which autonomy and sociotropy had unique associations with eating disturbances. Canadian female college students (N= 286) completed self-report measures of autonomy, sociotropy, depression, and bulimia as well as the Rorschach Inkblot Test. Findings suggest, contrary to Sugarman and colleagues' psychodynamic account, that experiences of dependency related to self-reported eating pathology do not necessarily lie outside of conscious awareness. Moreover, reported bulimic symptoms were uniquely associated with sociotropy but not autonomy-self-criticism among the participants.     

Impulsivity as a predictor of newly diagnosed depression

Depression is a severe mental disorder, whose onset has been related to environmental, genetic and personality factors. This study examined the association between impulsivity and incidence of depression. Logistic regression models were related to prospective data from two surveys (2-year time lag) conducted in a large cohort of hospital employees (N= 4,505). Only respondents with no history of depression at baseline were included. Impulsivity was predictive of the onset of depression (OR = 1.95, CI 95%= 1.28-2.97) after adjustment for age, sex and education. This association remained statistically significant after additional adjustment for a variety of baseline characteristics, such as smoking, alcohol consumption, and size of social network. A measure of mental distress (GHQ-12 responses), which may serve as a proxy measure for undiagnosed depression, was also associated with impulsivity. Impulsivity appears to be a distinct personality factor that may contribute to the onset of depressive illness in adults.     

Perceptions,emotions, and behavioral decisions in conflicts that escalate to violence

The present study tests the notion that cost-benefit considerations guide individuals’ emotional and behavioral responses when confronting an aggressive male stranger. Data was derived from hypothetical situations, with varying levels of opponent dangerousness and aggression severity, presented to 212 male and female students. Results indicate that the less dangerous the opponent and/or the more severe his aggression, the more intense are the respondents’ expected emotions of anger and fear and the higher the intended severity of respondents’ counter-aggression. While the expected emotional experience for female participants is more intense than for males, the intended behavioral counter-aggression is more severe for male participants than for females. Finally, an association between emotional experience and behavioral response was found only among males and it was mediated by opponent levels of dangerousness and aggression severity. Findings support the cost-benefit notion and emphasize the importance of studying aggression from an event perspective.

Deviant sexual arousal,offense history,and demographic variables as predictors of reoffense among child molesters

The present study examined selected demographic and offense history variables and deviant sexual arousal as predictors of reoffense in a group of 35 untreated child molesters. The measure of deviant sexual arousal was based on laboratory measures of sexual preference using penile plethysmography. Factor analysis of the predictor variables yielded three factors. The measure of deviant arousal, the amount of force used in the offense, whether or not the offender had intercourse with the child victim, and the number of previous victims loaded on the first factor, called Sexual Deviance. IQ and socioeconomic status loaded on the second factor, called Social Status. Age of the offender and age of the victim loaded on the third factor, called Offender Age. Entering the sets of three factor scores as predictors in a multiple correlation, over 20% of the variance in recidivism was explained, but the factor Sexual Deviance was the only significant predictor of recidivism (p < .02). Almost 30% of the variance in number of reoffenses was explained, and both Sexual Deviance (p < .01) and Social Status (p < .10) were significant predictors. A cluster analysis identified a group of offenders characterized by low SES and low IQ who also showed higher sexual deviance scores and a high rate of reoffense.     

Impulsivity, aggression, and serotonin: a molecular psychobiological perspective

The expression of aggressiveness, which constitutes many facets of behavior, is influenced by a complex interaction of biologic, psychologic, and social variables. Even though individual differences in impulsivity and the behavioral consequences, such as aggression, addiction, and suicidality, are substantially heritable, they ultimately result from an interplay between genetic variations and environmental factors. While formation and integration of multiple neural networks is dependent on the actions of neurotransmitters, such as serotonin (5HT), converging lines of evidence indicate that genetically determined variability in serotonergic gene expression influences complex traits including that of inappropriately aggressive behavior. This contribution reviews studies of major gene effects in inbred and knockout strains of mice with increased aggression-related behavior and discusses the relevance of several serotonergic gene variations in humans which include high aggressiveness as part of the phenotype. Although special emphasis is given to the molecular psychobiology of 5HT in aggression-related behavior in rodents, nonhuman primates, and humans, relevant conceptual and methodological issues in the search for candidate genes for impulsivity and aggressiveness and for the development of mouse models of aggressive and antisocial behavior in humans are also considered.     

Insight, rumination, and self-reflection as predictors of well-being

Dispositional private self-focused attention variables such as insight, internal self-awareness (ISA), and self-reflectiveness (SR) have been found to relate to well-being. The present study sought to determine which dispositional private self-focused attention variables have the most predictive power for subjective well-being as measured by the Satisfaction With Life Scale (E. Diener, R. A. Emmons, R. J. Larsen, & S. Griffin, 1985) and for a eudaemonic form of well-being as measured by the Psychological Well-Being Scale (C. D. Ryff, 1989). A total of 121 college student participants completed an online version of the Self-Consciousness Scale-Revised, the Rumination-Reflection Questionnaire, the Self-Reflection and Insight Scale, the Satisfaction With Life Scale, and the Psychological WellBeing Scale. Results of a multivariate regression analysis using the Self-Consciousness Scale-Revised's (M. F. Scheier & C. S. Carver, 1985) subfactors of SR and ISA, the Rumination-Reflection Questionnaire's (P. D. Trapnell & J. D. Campbell, 1999) subscales of Rumination and Reflection, and the Self-Reflection and Insight Scale's (A. M. Grant, J. Franklin, & P. Langford, 2002) Self-Reflection and Insight subscales revealed that the Insight subscale was the only statistically significant predictor (a positive predictor) for all 6 dimensions of psychological well-being. Insight was also the only significant positive predictor for satisfaction with life. The Rumination subscale was a significant negative predictor for 3 dimensions of psychological well-being, and the Reflection subscale was a significant positive predictor for 1 dimension. Implications of dispositional self-awareness variables and their relation to dimensions of well-being are discussed.     

Clustering of diet,physical activity and smoking and a general willingness to change

Addressing multiple health behaviours are important in preventing disease and mortality. The present study investigated the clustering of health behaviours, cognitive determinants and stages of change in 2827 adults for the lifestyle factors of physical activity, fruit, vegetable and fat consumption and smoking. The results showed that only 3% of the total population met recommended guidelines for all of the five behaviours. Behaviours were found to be weakly associated. Behaviour-specific cognitions and stages of change for the behaviours clustered more strongly, however. With respect to diet and physical activity, respondents in the preparation stage for one behaviour were likely also to be preparing to change another behaviour. Possible mechanisms for the apparent general willingness to change multiple behaviours are discussed, as well as potential implications for health promotion practice.     

Impulsivity, caffeine, and proofreading: a test of the Easterbrook hypothesis

Easterbrook's (1959) suggestion that arousal is inversely related to the range of cue utilization has been frequently cited as an explanation for the curvilinear relationship between arousal and performance. There is very little empirical support for this position, however. As a test of the Easterbrook hypothesis, 60 undergraduates who varied in their impulsivity level were given caffeine or placebo and then asked to proofread several passages. Estimates of sensitivity were calculated using signal detection techniques. It was predicted that high arousal would reduce sensitivity to interword errors, which require a broad range of cue utilization, but that the observed levels of arousal would not affect sensitivity to intraword errors, which require a minimal range of cue utilization. A significant crossover interaction between impulsivity and drug for interword errors indicated that caffeine increased the error detection rate of the (less aroused) more impulsive subjects but lowered the error detection rate of the (more aroused) less impulsive subjects. The results of this study support the suggestion that arousal has direct effects on the capacity for simultaneous information processing, independent of its effects on performance speed.     

The promotion of self-forgiveness,responsibility, and willingness to make reparations through a workbook intervention

This study evaluated the effectiveness of a workbook intervention designed to promote self-forgiveness, acceptance of responsibility, and willingness to make amends/reparations in a university student sample. The intervention manual consisted of three parts: (a) promoting prosocial and responsible attitudes, (b) reducing barriers to self-forgiveness, and (c) promoting healthy thinking and behaviors. Outcome measures included acceptance of responsibility, motivation to make reparations, and state and trait self-forgiveness. Measures were administered pre-intervention and immediately post-intervention. Participants were randomly assigned to an intervention group (N = 50) or a control group (N = 43). The control group studied materials for their university courses instead of completing the intervention. Following the intervention, the intervention group had significantly a higher state and dispositional self-forgiveness post-test compared to the control group. Changes in acceptance of responsibility and willingness to make reparations did not reach statistical significance as compared to the control group.
