Social sanction and threat explanations of gender effects on direct and indirect aggression

The present study examined two explanations for gender differences in expression of direct and indirect aggression. The social sanction model suggests that aggressor and target gender effects may be accounted for in terms of social sanctions against behaving aggressively; indirect aggression is the likely outcome of inhibitions against expression of direct aggression. The threat argument suggests that high levels of direct aggression in male‐male dyads as well as apparent inhibitions against harming females might be accounted for by the fact that males are more threatening targets than are females. Research participants completed a questionnaire measure of direct and indirect aggression twice, once with reference to their behavior toward a same‐gender target and once with reference to their behavior toward an other‐gender target. Although most direct aggression was reported by male aggressors toward male targets, gender of target did not relate to indirect aggression. Males reported approximately equal levels of indirect and direct aggression. Although females reported using more indirect than direct aggression, they did not differ from males in their reports of the frequency of use of indirect aggression. These results provided some support for both models of gender effects on human aggression and suggest the appropriateness of a relatively complex model of gender effects on aggression. Aggr.

Aggressive behavioral characteristics,hormones, and sexual orientation in men and women

Aggressive behavioral characteristics were assessed in groups of men and women by a self-report instrument, the Aggression Inventory, in which adult males reported more physical and verbal aggression than did females. Furthermore, males had higher scores on measures of impulsiveness and lack of frustration tolerance than did females, while women were more likely to avoid confrontation. In a second study, groups of male and female homosexuals and heterosexuals completed this Aggression Inventory after having blood samples taken to assay resting levels of testosterone (T) and estradiol (E). Groups of subjects within each gender were closely matched in terms of age, education, and vocational interests. Women were matched for the same time in their menstrual cycle (early follicular phase). Among men, homosexuals were indistinguishable from heterosexuals on all measures of aggression. Lesbians did not differ from heterosexual women on any aggression subscale except physical aggression, in which the homosexual women had lower scores. T and E were positively correlated with several indices of aggressive behavioral characteristics in men but were negatively correlated with those same measures in women.     

Anger rumination: an antecedent of athlete aggression?

Objectives. The aim of this study was to examine the relationship between anger rumination (the propensity to think almost obsessively over past experiences that have provoked negative affect in the form of anger) and athlete aggression. It was predicted that high levels of anger rumination would be associated with an increased propensity to aggress.Method. A questionnaire comprising the Anger Rumination Scale (Sukhodolsky, Golub, & Cromwell, 2001), aggression and demographic questions was distributed to 305 male and female competitive athletes of varying ability who represented several team and individual sports.Results. Principal component factor analysis revealed a single rumination factor rather than the four-factor solution previously described. No differences in Anger Rumination Scale score were found between males and females, team and individual sport players or competitive level. Provocation and anger rumination were significantly correlated with athletes’ reported aggressive behaviour. Aggression was higher in males compared to females. Type of sport was also related to incidence of aggression; athletes who participated in individual sports reported lower levels of aggression than athletes who played team sports.Conclusions. It was concluded that provocation and anger rumination were significant predictors of subsequent aggression and suggestions for preventing rumination, such as thought stopping and thought switching, were made.     

Assessing the role of aggression,empathy, and self‐serving cognitive distortions in trait emotional manipulation

This study extended the examination of the predictors of emotional manipulation. Participants (N = 243) completed measures of trait emotional manipulation, emotional intelligence, social skills, psychopathy, aggression, empathy, and self‐serving cognitive distortions in a cross‐sectional correlational design. For males, higher levels of emotional intelligence, social information processing, indirect aggression, and self‐serving cognitive distortions significantly predicted emotional manipulation. For females, being younger, higher levels of emotional intelligence, indirect aggression, primary psychopathic traits, and lower levels of social awareness significantly predicted emotional manipulation. However for females, emotional intelligence acted as a suppressor. These findings support previous indications that the mechanisms behind emotional manipulation differ as a function of gender. Future research could include ability, rather than trait measures of emotional manipulation, as well as the role of context (such as intimate relationships or workplace environments), thereby allowing additional examination of the nomological network of emotional manipulation.     

Relational aggression in college students: Examining the roles of social anxiety and empathy

This study examined the unique contributions of social anxiety and empathy to relational aggression in 300 19–to–25–year–old (M=21.25; SD=1.32) male (n=97) and female (n=203) college students using hierarchical linear regression analysis. The interactive relations between gender and social anxiety, and between gender and empathy, were also assessed. In addition to the gender and overt aggression covariates, fear of negative evaluation and perspective taking were unique predictors of relational aggression. Males, students who were more overtly aggressive, and those who reported greater fear of negative evaluation were more relationally aggressive than were peers. Students with higher levels of perspective taking reported using less relational aggression than did peers. A gender x empathetic concern interaction indicated that for males only, lower levels of empathetic concern were associated with higher levels of relational aggression. Results are discussed within a social information‐processing perspective. Aggr. Behav. 29:430–439, 2003. © 2003 Wiley‐Liss, Inc.     

Fear of failure and student athletes’ interpersonal antisocial behaviour in education and sport

Background. The link between fear of failure and students’ antisocial behaviour has received scant research attention despite associations between fear of failure, hostility, and aggression. Also, the effect of sport experience on antisocial behaviour has not been considered outside of the sport context in adult populations. Further, to date, sex differences have not been considered in fear of failure research. Aims. To examine whether (a) fear of failure and sport experience predict antisocial behaviour in the university and sport contexts in student athletes, and whether this prediction is the same in males and females; and (b) sex differences exist in antisocial behaviour and fear of failure. Sample. British university student athletes (n= 176 male; n= 155 female; M_age= 20.11 years). Method. Participants completed questionnaires assessing fear of failure, sport experience, and antisocial behaviour in both contexts. Results. (a) Fear of failure and sport experience positively predicted antisocial behaviour in university and sport and the strength of these predictions did not differ between males and females; (b) females reported higher levels of fear of devaluing one's self‐estimate than males whereas males reported higher levels of fear of important others losing interest than females. Males engaged more frequently than females in antisocial behaviour in both contexts. Conclusions. Fear of failure and sport experience may be important considerations when trying to understand antisocial behaviour in student athletes in education and sport; moreover, the potential effect of overall fear of failure and of sport experience on this frequency does not differ by sex. The findings make an important contribution to the fear of failure and morality literatures.     

Do Positive Self-Perceptions Have a “Dark Side”? Examination of the Link between Perceptual Bias and Aggression

The hypothesis that positive self-perceptions may have a dark side was investigated in the present study by examining the relationship between positively biased self-perceptions and aggression. Ratings of actual and perceived social acceptance of third-grade (n = 278), fourth-grade (n = 260), and fifth-grade (n = 321) students were compared to form a measure of perceptual bias. Peers provided nominations for overt and relational aggression. Gender differences were found for aggression (males were more overtly and relationally aggressive than females) but not perceptual bias. African-American children held more positive perceptions of their social acceptance and were perceived by peers as more aggressive than Caucasian children. Even after controlling for the effects of gender and ethnicity, more positively biased perceptions were associated with more peer nominations for overt and relational aggression. Contrary to an optimal range of bias hypothesis, even moderately positive self-perceptions were associated with elevated levels of aggression.     

Adolescent romantic relationships as a tug of war: The interplay of power imbalance and relationship duration in adolescent dating aggression

The present study investigates the link between power imbalance within the romantic couple and psychological, relational and physical adolescent dating aggression (ADA) perpetration, considering also the role of relationship duration as an indicator of the developmental stage of the relationship. This is the first investigation into whom is perceived to have power in the relationship (the partner or the subject him/herself) by distinguishing between male and female adolescents. Participants were 805 Italian adolescents (36.1% males; 63.9% females) aged 14–20 years (M_age = 17.16 years, SD_age = 1.34), all reporting having been in a romantic relationship currently or within the past 6 months. Males perceiving a balanced relationship reported lower levels of psychological ADA perpetration, and they perpetrated more relational ADA in longer relationships where the partner is perceived to have the power. No significant findings emerged regarding physical ADA. Females perceiving themselves as having the power in the relationship reported higher levels of psychological and physical ADA perpetration. They perpetrated more relational ADA when they perceived the partner as having the power in the relationship. Also, females in longer relationships in which power was not perceived as equally shared between partners reported higher physical ADA perpetration. Finally, for both males and females, longer relationships were characterized by higher levels of ADA toward the partner. Findings highlight the importance of studying the interplay between power imbalance and relationship duration on ADA perpetration, and provide the way to understand possible functions of ADA within a romantic relationship.     

Influence of school-level and family-level variables on Chinese college students’ aggression

With the frequent occurrence of campus violence, scholars have devoted increasing attention to college students’ aggression. This study aims to estimate the prevalence of aggression in Chinese university students and identify factors that could influence their aggression. We can thus find methods to reduce the incidence of college students’ aggression in the future. A multi-stage stratified sampling procedure was used to select university students (N = 4565) aged 16–25 years in Harbin. The Aggression Questionnaire, the Adolescent Self-Rating Life Events Checklist and the Social Support Revalued Scale were used to collect data. Females reported lower levels of aggression than males (p < .001). A multiple linear regression analysis was conducted to determine the influence of factors of aggression, and the model was highly significant (R² = .233, Ad R² = .230, p < .01). The results show that the aggression is affected by gender, family-level and school-level variables. Aggression scores are significantly correlated with not only family-level or school-level variables independently, but their combination as well. We find that the risk factors for aggression include a dissatisfying profession, higher levels of study pressure, poor parental relationships, poor interpersonal relationships, the presence of siblings, punishment, health maladjustment, less subjective support, and lower levels of utilization of social support.     

Does bullying others at school lead to adult aggression? The roles of drinking and university participation during the transition to adulthood

This study uses a three‐wave longitudinal study of young Australians to identify developmental processes underlying the relationship between school bullying and physical aggression in early adulthood. The central question is whether and how drinking and participation in work or university study disrupt or entrench aggressive pathways from school bullying to adult aggression. Self‐report data were collected from 88 females and 63 males (N = 151) during childhood (age 10), adolescence (age 14), and early adulthood (age 20). Participants who bullied other students during childhood and adolescence, or during adolescence only, reported more physical aggression during early adulthood than those who never bullied. However, those who had bullied during adolescence only reported significantly higher adult aggression if they were also drinking at above‐average frequencies. Conversely, participation in university, compared to being in the workforce, was associated with significantly less adult aggression among the at‐risk groups. Findings suggest that particular contexts during early adulthood can offer youth on aggressive trajectories (as evidenced by bullying at school) unique opportunities to turn their behaviour around. Other contexts, however, may exacerbate aggressive behaviour patterns.     

Getting a Life: Gender Differences in Postwar Recovery

This study examined gender differences in stress symptoms and recovery one year after the end of war, among two Israeli samples (adults n?=?870 and adolescents n?=?810). MANOVA analysis indicated that females reported higher levels of stress symptoms and lower levels of postwar recovery compared to males. Adolescents reported lower levels of stress and higher levels of recovery compared to adults. Path analysis supported the following: Gender associated negatively with family support and sense of danger. Sense of danger associated positively with symptoms and negatively with recovery, while family support associated with these variables in the opposite direction. Mediation test indicated that family support and sense of danger served as mediators between gender and recovery and between gender and stress symptoms.     

The effects of feedback on the gender differences in the performance in a chronometric mental-rotation test

ABSTRACT

Gender differences favouring males are often found in mental-rotation tests and are usually smaller in chronometric than in psychometric test. The individual feedback in the chronometric test could be an explanation for the comparable performance of males and females. To test this hypothesis, 102 undergraduate students (60 females, 42 males) participated in a chronometric mental-rotation study with or without feedback. A subsample of 41 participants was asked to report their confidence about their performance in the test. In reaction time, males outperformed females and participants in the feedback condition reacted faster than participants without feedback. A significant interaction of gender and condition was found. Only females had an advantage in the feedback condition in reaction time while there was no difference for males. Males reported higher scores of confidence. Feedback seemed to help females especially to react faster. Confidence levels are discussed as reasons for differences between conditions and genders.     

High maternal aggression in dwarf hamsters (Phodopus campbelli and P. sungorus)

The defense of offspring, termed maternal aggression, is a highly conserved behavior in mammals, including rodents. This study examined relative levels of maternal aggression in two closely related dwarf hamster species, Phodopus campbelli and P. sungorus, that normally inhabit high latitude, boreal environments. When tested with first litters and with the breeder male remaining with the female (for P. campbelli the male is necessary for successful rearing of offspring), both species exhibited high levels of maternal aggression with average duration of aggressive behavior>80 sec for a 10 min test. For P. sungorus, males are not required to rear offspring. P. sungorus females with either one or multiple litters (singly housed after impregnation) exhibited significantly higher levels of aggression (>300 sec) relative to females co‐housed with the sires. In terms of species differences in attack style, P. campbelli exhibited a boxing or clawing strategy for ～50% of total attack time, but for P. sungorus, this form of attack occurred<5% of the time. For P. sungorus, attacks to the vulnerable belly and flank constituted>90% of all attacks, but these regions were attacked ～50% of the time for P. campbelli. A survey of levels of maternal aggression of rodents in other genera suggests that maternal aggression in Phodopus is at the high end of the spectrum. Results of this study suggest that the presence of the breeder male may actually suppress aggression in P. sungorus. This fact, as well as its high level of aggression and its distant relationship to mice and rats, suggest P. sungorus as a possible model for future studies on the neurobiological basis of maternal aggression. The relationship between the high rates of maternal aggression and life history strategy in Phodopus is discussed. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.     

Sex differences in processing aggression words using the Emotional Stroop task

There is a robust relationship between the salience of stimulus materials presented in the Emotional Stroop task and inhibition of response in clinical populations. Researchers have now found information‐processing biases in both forensic and non‐forensic samples presented with threatening or aggressive stimuli [Cohen et'al., 1998; Eckhardt and Cohen, 1997; Smith and Waterman, 2003; Van Honk et'al., 2001]. We sought to explore sex differences in processing words relating to acts of direct and indirect aggression using a group of undergraduates (50 males and 50 females). Participants also completed self‐report questionnaires (AQ and EXPAGG) to allow some consideration of the relationship between objective and subjective measures. We predicted that males would demonstrate delayed responses when presented with words relating to acts of direct aggression. We also predicted that high levels of physical aggression would be the best predictor of bias for direct aggression words, high levels of verbal aggression would be the best predictor of bias for indirect aggression words, physical aggression would predict bias in males, and verbal aggression would predict bias in females. Males demonstrated a perceptual bias for words relating to acts of direct aggression, taking significantly longer to correctly colour name direct aggression words. Females were slower to correctly colour name indirect aggression words, but not significantly so. Verbal aggression, as expected, predicted bias performance for indirect aggression words but anger rather than physical aggression was the best predictor of bias for direct aggression words. Gender was a predictor for bias with both sets of words. Contrary to our predictions, it was observed that a high level of physical aggression was the best predictor of bias in both males and females. These data provide further evidence to confirm the saliency of aggression words to aggressive individuals in non‐forensic populations. Aggress. Behav. 00:00–00, 2005. © 2005 Wiley‐Liss, Inc.     

College Students and Community Service: Who,With Whom,and Why?

The community service volunteer vs. nonvolunteer status of 124 college students was examined in relation to motivation, gender, extraversion-introversion, and social anxiety. Volunteers and female students were hypothesized to have higher levels of motivation to participate than were nonvolunteers and males, and to have higher levels of interest in volunteering. The data for volunteer status and gender were significant only with respect to interest in volunteering, with volunteers and females significantly more interested in volunteering than were nonvolunteers and males. Gender differences were also found for volunteering style preference and participation within particular volunteer groups. Volunteers were also hypothesized to have lower levels of extraversion and higher levels of social anxiety than nonvolunteers because socially anxious introverts were thought to seek the anxiety-reducing structure of a volunteer activity. This hypothesis was not supported.     

Hypothalamic Pituitary Adrenal Axis Functioning in Reactive and Proactive Aggression in Children

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to elicit fear (N = 33) or frustration (N = 32), or a validity check condition (N = 8). This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples for cortisol analysis were collected including 12 post-stress samples at 5-min intervals. Reactive and proactive aggression levels were assessed via the teacher-completed Aggression Behavior Teacher Checklist (Dodge and Coie, J Pers Soc Psychol, 53(6), 1146–1158, 1987). Reactive aggression significantly predicted total and peak post-stress cortisol regardless of stress modality. Proactive aggression was not a predictor of any cortisol index. Examination of pure reactive, proactive, combined, or non-aggressive children indicated that reactive aggressive children had higher cortisol reactivity than proactive and non-aggressive children. Our data suggest that while an overactive HPA-axis response to stress is associated with reactive aggression, stress induced HPA-axis variability does not seem to be related to proactive aggression.     

Achievement goal orientations,beliefs about sport success and sport emotions as related to moderate to vigorous physical activity of adolescents

Abstract

This study examined the relationships between achievement goals, beliefs about sport success and sport emotions with moderate to vigorous physical activity of Estonian adolescents. Three hundred and seventy five adolescents, aged 13–14 years, completed the Task and Ego Orientation in Sport Questionnaire and 7-day physical activity recall. Measures of the adolescent's orientation to work avoidance, focus on cooperation, beliefs about the causes of success and degree of satisfaction/interest specific to the context of sport and games were also included. Moderate to vigorous physical activity (MVPA) quartiles were determined and psychological measures for extreme activity groups were compared. A one-way ANOVA indicated that active males scored significantly higher in task orientation, motivation/effort, ability and enjoyment/interest whereas active females showed higher scores for cooperation and exercise enjoyment and lower deception and boredom compared with low activity groups. Correlation analysis revealed that in males, MVPA was related with task orientation, reported ability and motivation/ effort. For females, cooperation, and enjoyment of sport were positively and the amount of boredom was negatively associated with MVPA scores. Multiple regression analysis revealed that psychological measures explained only 14% (females) and 19% (males) of the variance in MVPA. It is concluded that for adolescent males and females, different psychological measures predicted MVPA behavior.     

The Association Between Church Attendance and Psychological Health in Northern Ireland: A National Representative Survey Among Adults Allowing for Sex Differences and Denominational Difference

This study extends previous research concerning the association between religion and psychological health in six ways: (1) by focusing clearly on religious attendance (church attendance); (2) by employing a robust measure of psychological distress (GHQ-12); (3) by studying a highly religious culture (Northern Ireland); (4) by taking sex differences into account (male or female); (5) by taking denominational differences into account (Catholic or Protestant); (6) and by obtaining a national representative sample (N = 4,281 adults aged 16 and above). Results from a 2 (sex) by 2 (denomination) ANCOVA demonstrated that Catholics recorded significantly lower levels of psychological health compared to Protestants, and that females showed significantly lower levels of psychological health compared to males. In addition, females reported higher frequency of religious service attendance than males, and Catholics reported higher attendance rates than Protestants. A significant positive association was found between frequency of religious attendance and GHQ-12 scores, and this association was moderated by sex and denomination. In conclusion, the results suggest that there may be sex and denominational differences in further understanding the relationship between frequency of religious attendance and psychological health.     

Self-disclosure: Intimate and nonintimate disclosures to parents and best friends as a function of bem sex-role category

Thirty-two androgynous, traditional, and undifferentiated males and females (N/it=192) completed a 6-item self-disclosure questionnaire containing 30 intimate and 30 nonintimate items. The targets were father, mother, and best male and female friends. Analyses of both intimate and nonintimate items indicated that amount of self-disclosure was related to sex role and not gender. Typical male-female differences in self-disclosure were not found because (a) androgynous males disclosed at significantly higher levels than traditional and undifferentiated males to most targets; (b) undifferentiated males and females disclosed significantly less than their androgynous and traditional counterparts. Intimate self-disclosure by androgynous males to father, and nonintimate disclosure by androgynous females to father, were particularly high. Both findings suggest a unique role for fathers in the development of androgynous persons. Androgynous females reported higher disclosure to best male friend than to mother. This is counter to the traditional female pattern and is interpreted as representing a greater degree of distancing from mother and openness to peers.The order of the authors' names was randomly determined. Both contributed equally.     

Screening for Adolescent Substance‐Related Disorders Using the SASSI‐A2: Implications for Nonreporting Youth

In this study (N = 137), although 70.8% of participants reported no current substance use and 42.3% reported never using, the Adolescent Substance Abuse Subtle Screening Inventory (SASSI‐A2; Miller & Lazowski, 2001) screened 39.41% of the participants for a high level of probability of having a substance‐related disorder. SASSI‐A2 classified more females in our sample as having a high probability of substance‐related disorder than males. Among African American participants, male adolescents had substantially higher levels of drug use and significantly lower levels of alcohol use than did female adolescents. Implications, limitations, and future directions are provided.
