Judgments Regarding Sexual Aggression as a Function of Sex of Aggressor and Victim

The effects of sex of aggressor and victim (male/female, female/male, male/male, female/female) on judgments regarding sexual aggression on a date were studied. Participants were 415 female and 279 male community college students (M age = 23.0 years; 47.3% European American, 18.6% Latin American, 7.5% African American, 7.8% South East Asian American, 3.7% Asian American, and 15.1% other) who read one of four vignettes describing a date in which forced intercourse occurred. Participants rated degree of disapproval of the aggressor's behavior from their own viewpoint (Participant Rating), the victim's viewpoint (Victim Rating), and the aggressor's viewpoint (Aggressor Rating). Results of 4 × 2 (Vignette × Participant Gender) ANOVAs of Participant Rating and Victim Rating indicated similar disapproval of the aggressor for all couple types except for female aggressor/male victim, for whom disapproval was significantly lower. The aggressor's overall behavior was rated as date/acquaintance rape by 46.6–55.4% of participants for all vignettes except the female aggressor/male victim vignette (18.7%).     

Aggression in the Laboratory: Problems with the Validity of the Modified Taylor Competitive Reaction Time Test as a Measure of Aggression in Media Violence Studies

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity.     

Strength of a Secondary Reinforcement as a Function of the Quality of Food Reward

Thirty-two children were presented 18 stories containing either a good, neutral, or negative act which was followed by either a reward or punishment. It was predicted that Ss' responses would be influenced by the sanctions. It was also predicted that the type of story (good, neutral, or bad) would influence the extent to which a child judged the act independent of the effects of the sanction (reward or punishment).

These predictions were supported. Ss made more positive responses to acts followed by reward than to those followed by punishment. However, an examination of a Content × Sanction interaction found the sanction of reward relatively ineffective for the stones with negative content.     

Attachment and Relational Aggression: Power as a Mediating Variable

Evidence illustrates that insecure romantic attachment predicts higher levels of relational aggression. However, no research has attempted to explain that relationship with mediating variables, such as relationship power, which is associated with attachment and partner violence. Data for this study included 457 couples from Wave 2 of the Flourishing Families Study. Actor Partner Interdependence results indicated that insecure attachment was significantly predictive of relational aggression actor effects. There was also a significant partner effect between male insecure attachment and female relational aggression, and power was a significant mediator between attachment and relational aggression for males and females.     

Declines in Major League Batting Performance as a Function of Game Pressure: A Drive Theory Analysis1

Zajonc's (1965) drive theory explanation argues that greater arousal tends to impair performance on difficult tasks. The hypothesis that arousal generated by “pressure situations” during major league baseball games would hinder batting performance—a difficult task—was tested by examining such performance during the 1989 season. Six “pressure situations” were identified, some occurring during the late innings of close games and others occurring throughout the game when there were two outs. Two measures of batting performance (batting average and slugging average) were employed. Results indicated broad support for the hypothesis. Reasons for this pattern are discussed, as are possible alternative explanations for these findings.     

Emotional Skillfulness as a Key Mediator of Aggression

Psychological research has documented several predictors of aggression, including adherence to hegemonic masculinity, trauma symptoms, and insecure attachment. However, at present, little is known about why these variables predict aggression. This study used acceptance theory to introduce the concept of emotional skillfulness as a counterpoint to emotion dysregulation. In an effort to better understand the pathways through which these variables predict aggression, this study used a clinical sample to test three mediational models which hold that emotional skillfulness functions as a common link between the aforementioned predictors and aggression in both men and women. Results indicated that emotional skillfulness is a mediator of aggression for both men and women, but that the predictors of aggression differed by gender.     

Implicit Coping Styles as a Predictor of Aggression

Research exploring potential antecedents of aggression provides contradictory results, with some data relating adaptive coping styles with high aggression and other studies finding the inverse. Clarification of these relationships could improve intervention and prevention strategies. This study investigated relationships between aggression and 3 coping styles (adaptive, neurotic, and maladaptive) via cross-sectional correlational methodology (N = 355). Data supported both hypotheses: First, the use of less adaptive coping styles predicted higher levels of aggression; second, this relationship held true for both cognitive (anger and hostility) and overt (physical and verbal) expressions of aggression. Results indicate that maladaptive coping significantly predicts aggression. Implications include potential prediction and prevention strategies to reduce the probability of higher risk individuals exhibiting aggression.     

Aggression as a reinforcer: operant behavior in the mouse-killing rat

Two experiments examined mouse killing as a reinforcer of key pressing by rats that killed mice. In Experiment I, mouse-killing rats performed the key-pressing response when each press was reinforced with presentation of a mouse. Offered a choice between a key that yielded presentation of mice and one that did not, the rats preferred the key that yielded mice. When the contingency was reversed, the rats preferred the other key and continued to kill mice. In Experiment II, mouse-killing rats that did not kill rat pups performed a key-pressing response reinforced with presentation of mice on a variable-interval schedule. In tests for responding reinforced on that schedule with presentation of normal mice, anesthetized mice, dead mice, or rat pups, these rats that killed mice but not rat pups exhibited a decline in response rate when rat pups were the reinforcer. Altering the condition of the mice did not significantly affect performance.     

Aggression in African-American boys: a discriminant analysis.

The main purposes of this study were to determine whether familial variables found to be related to the development of aggressive behavior in Caucasian boys may also be related to similar aggressive patterns in inner-city African-American boys and to assess the relative importance of these variables for classifying the subject population into aggressive and nonaggressive groups. Discriminant analyses were performed using 83 African-American boys, with a mean age of 13.9 years, who were classified as institutionalized aggressive, noninstitutionalized aggressive, and noninstitutionalized nonaggressive subjects. Although the same father and mother variables were used in the analyses, the father variables were not related to group membership. Furthermore, the results showed that both groups of aggressive boys reported more aggression within as well as outside their family home settings than their nonaggressive counterparts. Socioeconomic-related factors such as employment status of parent(s), size of family, and number of parents in the household were not useful predictors of aggressive and nonaggressive group membership.     

Attractiveness as a Function of Skin Tone and Facial Features: Evidence from Categorization Studies

Participants rated the attractiveness and racial typicality of male faces varying in their facial features from Afrocentric to Eurocentric and in skin tone from dark to light in two experiments. Experiment 1 provided evidence that facial features and skin tone have an interactive effect on perceptions of attractiveness and mixed-race faces are perceived as more attractive than single-race faces. Experiment 2 further confirmed that faces with medium levels of skin tone and facial features are perceived as more attractive than faces with extreme levels of these factors. Black phenotypes (combinations of dark skin tone and Afrocentric facial features) were rated as more attractive than White phenotypes (combinations of light skin tone and Eurocentric facial features); ambiguous faces (combinations of Afrocentric and Eurocentric physiognomy) with medium levels of skin tone were rated as the most attractive in Experiment 2. Perceptions of attractiveness were relatively independent of racial categorization in both experiments.     

Capoeira as a Clinical Intervention: Addressing Adolescent Aggression With Brazilian Martial Arts

This article integrates martial arts and therapeutic principles into a culturally sensitive model that cultivates change in the aggressive behaviors of disenfranchised adolescents. The art form of Capoeira is proposed for promoting positive behavioral change. La agresión en los adolescentes es dañina y emocionalmente devastadora para los jóvenes y sus comunidades. Este artículo integra artes marciales y principios terapéuticos en un modelo culturalmente sensible que cultiva el cambio de los comportamientos agresivos de los adolescentes marginalizados. Se propone el arte de la Capoeira para promover un cambio positivo en el comportamiento.     

Direct and Indirect Aggression: Relationships as Social Context

The studies reported in this paper examined the effect of social context—target gender and target relationship—on reports of direct and indirect aggression. In Study 1, participants completed the Richardson Conflict Response Questionnaire (RCRQ; Richardson & Green, 2003 ), which measured their direct and indirect aggression behavior in response to anger. Participants also selected a relationship partner to complete the RCRQ with reference to their own (i.e., participants') behavior. In Study 2, participants completed the RCRQ with reference to their behavior in response to anger with a romantic partner, a same-sex friend, and an opposite-sex friend. In both studies, relationship with aggression target was an important determinant of aggression, with more direct aggression occurring in romantic relationships, and more indirect aggression occurring in friendship relationships.     

Aggression,anger and hostility: Evaluation of moral disengagement as a mediational process

This study examines how the mechanisms underlying moral disengagement serve as a mediator between anger and hostility and physical and verbal aggression. The study was carried out on 424 participants (61.1% females), aged 15 to 25 years, assessing the direct and indirect effects of the distinct variables using a hierarchical multiple regression analysis and structural equation modeling. The findings suggest that anger and hostility contribute independently and positively to physical and verbal aggression. Moreover, the relationships between anger, hostility, and aggression appear to be mediated by moral disengagement. Indeed, this process of mediation was invariant across sexes, and it tended to be stronger for physical – as opposed to verbal – aggression.     

Studies of Motor Function in Schizophrenia: III. Steadiness

Younger and older adults performed lexical decisions on ambiguous words, unambiguous words, and pseudowords, and simultaneously responded to an auditory probe presented at stimulus onset asynchronies (SOAs) of 90, 180, or 270 ms. For both age groups, lexical decisions and probe responses were faster for ambiguous words than for unambiguous words, and slowest for pseudowords. For the older adults, but not the younger adults, lexical decisions were slower when the probe was presented (the dual-task condition), compared with a control condition in which the lexical decision was performed alone. The older participants also showed slower tone-detection responses in the dual-task condition than when the tone was presented alone. For all participants, proportional tone-detection times (compared with tones in isolation) decreased with increasing SOA, but this decrease was less pronounced in the older group. Finally, the time between responses in the dual-task condition was longer for older than for younger adults. The results indicate that word meaning influences the allocation of attention similarly for younger and older adults, but that older adults suffer a cost and become disproportionately slower in processes related to response coordination and output.     

Reason to Believe: Representations of Aggression as Phenomenological Read-Out

Men tend to view their own aggression as an instrumental act aimed at imposing control, whereas women tend to view theirs as an expressive act resulting from a loss of self-control. These interpretations have been called social representations based on their presumed social origins and mode of transmission. However, if women’s self-control is generally higher than men’s, they would be expected to behave aggressively only infrequently and at higher levels of provocation. Aggression would be experienced phenomenologically as a loss of self-control. In Study 1, a student sample, men scored higher than women on instrumental beliefs, impulsivity, and risk seeking. As predicted, instrumental beliefs were associated with higher impulsive risk seeking and an expressive representation was positively associated with temper. In Study 2, an offender sample, there were no gender differences in instrumental beliefs, physical aggression, temper, carelessness, and present orientation. Instrumental beliefs were again associated with impulsive risk seeking and, to a lesser extent, temper. Expressive beliefs were again associated with temper and, to a lesser extent, present orientation. Physical aggression was associated with holding instrumental beliefs, impulsive risk seeking, and temper. The model is broadly supported and directions for future work are suggested.
