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.     

An experimental approach to the study of learned aggression

The sensory contact technique increases aggressiveness in male mice and allows aggressive types of behavior to be formed as a result of the repeated experience of victories in daily agonistic confrontations. Some behavioral domains confirm the development of learned aggression in males similar to those in humans. The features are repeated experience of aggression reinforced by victories; elements of learned behavior after periods of confrontation; intent, measured by increase of the aggressive motivation prior to agonistic confrontation; and decreased emotionality, estimated by parameters of open‐field behavior. Relevant situation provokes increases in aggression (boundary aggression). This review summarizes data on the influence of positive fighting experience in daily intermale confrontations on the behavior, neurochemistry, and physiology of aggressive mice (winners). This sort of experience changes many characteristics in individual and social behaviors, these having been estimated in different tests and in varied situations. Some physiological parameters are also changed in the winners. Neurochemical data confirm the activation of brain dopaminergic systems and functional inhibition of serotonergic system in winners under the influence of the repeated experience of aggression. The expression of the neurochemical and behavioral changes observed in winners has been found to depend on the mouse strain and on the duration of their agonistic confrontations. Aggr.

Immediate and sustaining effects of extrinsic rewards on specific exploratory behavior

The purpose of the present investigation was to examine the immediate and sustaining effects of monetary and social rewards on specific exploratory behavior. Specific exploratory behavior was conceived as a behavioral expression of intrinsic motivation and was measured by the number of additional requests for viewing blurred tachistoscopically presented slides of varying degrees of uncertainty. The results of the study showed that when monetary and social rewards were presented contingent on performance, exploration increased at the upper levels of uncertainty above a control group. It was also found that after removal, females who had previously received social rewards sustained a significantly higher level of exploration above the control group, while males who had previously received social rewards, as well as both males and females who had previously received monetary rewards, did not differ significantly from the control. The discrepany between these findings and previous findings is explained in terms of theoretical differences in defining and measuring intrinsic motivation.     

价值取向与社会距离影响经济决策的合作与冲突行为：Chicken Game的证据

采用Chicken Game博弈任务,考察了不同社会价值取向个体（亲社会者与亲自我者）在面对不同社会距离的博弈对手（朋友和陌生人）时表现出的合作与冲突行为。研究结果发现：（1）社会价值取向与社会距离交互影响个体的合作与冲突行为;（2）社会价值取向影响选择策略的反应时,亲社会者选择合作的反应时长于选择冲突的反应时,亲自我者选择合作与选择冲突的反应时没有显著差异;（3）无论对亲社会者还是亲自我者,反馈类型都显著影响个体的合作与冲突行为的选择率以及随后决策的反应时。上述结果表明,个体的合作或冲突行为,并非单一地受到社会价值取向的影响,更可能是受到个人因素（社会价值取向）与其他社会因素（比如,社会距离）的共同调节,并且在这一过程中个体会根据决策后反馈信息不断的调整自己的行为策略。     

Parental Stress and Children’s Social and Behavioral Outcomes: The Role of Abuse Potential over Time

Parental stress is a well-established risk factor for adverse child outcomes, including the development of aggression, externalizing behavior problems, and anxiety, as well as compromised emotional coping, impaired social cognition, and diminished treatment response. Abuse potential represents a mechanism by which parental stress may impact child social competence and behavior; evidence links parental stress to abuse potential, and abuse potential to a range of negative child social competence and behavioral outcomes. The current study assessed relationships between parental stress, abuse potential, and child social and behavioral outcomes over time. Parents of children ages 2–6 years (N?=?610, 44% girls) reported on perceived parental stress and attitudes towards abuse and neglect, as well as child social competence and behavior problems, before and after a caregiver-directed, community-based intervention. Changes in parental stress, abuse potential, and child social and behavioral outcomes were examined using panel analyses, while controlling for intervention effects and demographic variables. Parental stress predicted child social competence, anxiety/withdrawal, and anger/aggression over time; while the links between stress and anxiety/withdrawal, and stress and social competence, were mediated by child abuse potential, the link between stress and anger/aggression was not mediated by child abuse potential. Findings suggest that abuse potential represents a mechanism by which parental stress and child social and behavioral outcomes are linked. Further, screening for child social competence deficits may identify children at risk for abuse, as well as parents in need of services to reduce stress.     

Effects of fluprazine (DU 27716) upon aggressive and sexual behavior of testosterone-treated female rats

Female rats, chronically treated with Testosterone Propionate (TP), were injected with Fluprazine (DU 27716) or saline and tested for social aggression, masculine and feminine sexual behavior. Fluprazine-treated females were less aggressive than saline-treated females, as indicated by a shift from offensive to less offensive parameters of aggression. At the same time, mounting in Fluprazine-treated females was almost totally abolished, both in aggression tests and in tests for sexual behavior. Feminine sexual responses increased during aggressive encounters but were slightly inhibited when females were confronted with sexually active males. Females treated with Fluprazine and tested for mounting with a receptive female showed a substantial increase of offensive aggression directed at the receptive stimulus female. It is concluded that Fluprazine does not selectively inhibit offensive aggression in TP-treated female rats.     

Aggressive behavior in inbred strains of mice during pregnancy

Female aggressive behavior toward adult male ICR/JCl mice was compared for virgin and pregnant mice of five inbred strains (BALB/c, C3H/He, C57BL/6, DBA/2J, and AKR/J). Pregnant females from four strains except BALB exhibited intense aggressive behavior, whereas only virgin AKR females were aggressive. Aggressive behavior began in early pregnancy, was highest in midpregnancy, and declined slightly thereafter until the day of parturition. The level of aggressive behavior showed significant strain differences. The topography of aggressive behavior was also different among the four strains. DBA females showed marked contrast with the other three strains in the temporal changes of aggression in the first phase of encounter. Furthermore, strain specific behavioral pattern of aggression was demonstrated based on six behavioral acts ( Darting , Chasing, Attack, Biting, Wrestling, and Boxing). Virgin and pregnant AKR females showed the identical behavioral pattern of aggression.     

Effects of neonatal treatment with 1-(2,5-dimethoxy-4-lodophenyl)-2 aminopropane HCI (DOI) and ritanserin on agonistic behavior in adult male and female rats

The role played by the neonatal 5-hydroxytryptamine (5HT) system in the organization and sexual differentiation of adult agonistic behavior was investigated in rats. Focus was on the 5HT2 receptor subtype, which has been demonstrated to be involved in agonism control in the adult. 5HT2 activity was experimentally manipulated by administration of a specific agonist [1-(2, 5-dimethoxy-4-iodophenyl)-2-aminopropane HCl (DOI)] or antagonist (ritanserin) during the second week of life, when serotonin is known to concur to anatomical and behavioral sexual differentiation. Interactions between early 5HT2 activity, genetic sex, and neonatal circulating testosterone (T) were studied by administering the ligands to males, females, and androgenized females. At adulthood, the animals were tested for both aspects of agonism, i. e., aggression and defense, in a 20-min confrontation with an unfamiliar conspecific of the same sex, age, body weight, and social experience. Neonatal administration of the 5HT2 antagonist ritanserin increased aggression independently of sex; it also increased defense, but this effect was confined to males. The agonist DOI had no effect on aggression, but enhanced defense in males and androgenized females, with an effect which depended therefore more on neonatal T than genetic sex. Females appeared in general less sensitive to neonatal 5HT2 manipulation than both androgenized females and males; this suggests that neonatal T is crucial for experimental modifications of neonatal 5HT2 activity to have any consistent effect on adult agonistic behavior. On the other hand, effects observed in males and androgenized females were dependent on the behavior considered and the drug administered. This was especially evident for defense, enhanced by ritanserin in males only, and in both males and androgenized females by DOI. Neonatal 5HT2 activity seems therefore to play a role in the modulation of adult agonistic behaviors, which depends on the behavior considered and is under multiple control of genetic sex and hormonal neonatal substrate. © 1994 Wiley-Liss, Inc.     

The Effect of Stress on Spontaneous Nest Leaving Behavior in the Mouse: An Improved Model of Stress-Induced Behavioral Pathology

The present experiments were conducted to develop a more sensitive and reliable model of stress-induced behavioral pathology in the mouse. Male mice were housed singly in nest cages connected to either a circular tunnel, a recreational cage or a large box with food foraging apparatus. Spontaneous nocturnal out of nest activity or food foraging behavior in these environments was continuously monitored for a two week period during which time the effects of stress were examined. It was found that both repeated restraint and aggression stress markedly and persistently reduced out of nest nocturnal activity or food foraging behavior in all 3 environments but did not alter activity in a novel open field or plus maze or food or saccharin intake in the nest cage. In a preliminary experiment the reduction in out of nest activity by stress was attenuated by prior chronic treatment with the antidepressant, desmethylimipramine. Plasma corticosterone was elevated immediately after aggression stress but reduced 5 hr after chronic aggression stress. The reduction in activity did not appear the result of increased anxiety as measured by spontaneous risk assessment behavior in the nest. It is concluded that the decrease in out of nest activity after stress in the present studies models a withdrawn behavioral state and may be due to either or both a decrease in appetitive motivation to leave the nest or an increased aversion to the external environment which does not apparently involve anxiety.     

Characteristics of male and female prisoners involved in bullying behavior

This study explores bullying behavior in a larger and more representative sample than previous prison-based research. It has two core aims, first to explore the nature of bullying in relation to indirect and direct aggression and, second, to explore the predictors of bully-category membership with particular reference to behavioral characteristics. Participants were adult men (n=728) and women (n=525) prisoners. All completed a behavioral measure of behavior indicative of bullying (Direct and Indirect Prisoner behavior Checklist, DIPC) that also explored prison-based behavior such as negative acts towards staff or prison rules, positive acts and drug-related behavior. Indirect aggression was, as predicted, reported more frequently than direct aggression, although this only held for perpetration. Bully-victims, as predicted, showed more negative behavior. Pure bullies and pure victims also showed more negative behavior than the other categories. The findings are discussed in relation to the environment in which bullying behavior is being assessed and with attention to the possible motivations underlying both bullying and negative behavior. Directions for future research are suggested.     

Social facilitation

Video-recording procedures have been used in previous research as a motivational manipulation. The present study investigated the permanent recording of behavior as a manipulation of evaluation apprehension and its effects upon behavioral performance and upon autonomic arousal. Twenty-four subjects (12 males, 12 females) were randomly assigned to one of four conditions formed by completely crossing two levels of audience status (peer or authority) with two levels of behavioral record (non-permanent or permanent). Another 24 subjects were assigned to an external control group to the 2×2 design. Subjects' performance on a hidden-word task and their arousal level (as assessed by the Palmar Sweat Index) were measured. Analyses of variance results showed a significant performance (p<.05) and a significant arousal (p<.05) difference between the behavioral record conditions as predicted. The control group was also found to be significantly (p<.05) different from the experimental groups on the behavioral performance measure. The results were related to previous research findings and interpreted within the context of the evaluation apprehension notion presented within social facilitation research.The author would like to thank Angelia Mellors, Valerie K. Golish, and Judy Cohen for serving as experiments, and Susan L. Doman and Cheryl Primmer for scoring the PSI measures.     

Dimensions of response to novelty are associated with social engagement and aggression in adult male rhesus macaques (Macaca mulatta)

In this study, the authors tested the hypothesis that behavioral response across social and nonsocial, novel and familiar conditions may be guided by the same trait(s) related to impulsivity in adult male rhesus macaques. The authors assessed 23 individuals' behavioral response to a series of nonsocial novel scenarios, as well as aggression and sociality within familiar and novel social contexts. Factor analysis of responses to nonsocial novelty identified two factors: Caution, which reflected latency to engage different novel situations, and Interest in Novelty, which consisted of duration and quality of exploration. Each dimension was associated with different social manifestations. Caution was negatively correlated with social aggression in novel and familiar social circumstances; Interest in Novelty was positively associated with social engagement in familiar, but not novel, social circumstances. The authors conclude that traits influencing impulsive response to novelty contribute to risky and normal social behavior across social contexts.     

Rural adolescent aggression and parental emotional support

Preliminary research findings suggest important distinctions between rural and urban adolescent aggression risk and protective factors. Despite these potentially important differences, most of the existing research on adolescent aggression has utilized urban samples. The current study examines the direct association between parental emotional support and rural adolescent aggression, and whether adolescent psychopathology and substance abuse mediate this association. Multi-method measurement (self-report, parent report, and behavioral observations) were employed in measuring aggression and emotional support variables with rural, nonadjudicated adolescents (N=62) and their mothers or stepmothers. Results indicated that parental emotional support has an indirect influence on adolescent aggression. Adolescent substance abuse was completely mediated by adolescent grade-point average, indicating no significant direct impact on aggression. Adolescent psychopathology significantly mediated the relationship between parental emotional support and adolescent aggression. Particular items contributed substantially to this mediating association, making certain characteristics, rather than a specific diagnosis, relevant to psychopathology's mediating impact. These characteristics include cognitive perception of others as critical or hostile, emotional anxiousness in social situations, and behavioral persistence in social interactions despite these perceptions.     

Social cognition and aggression in delinquent adolescent males

The relationship of aggression to several social cognitive variables in delinquent adolescent males was investigated. Subjects were fifty-eight institutionalized males identified by peers as high-aggressive or low-aggressive. Participants were administered measures of perspective taking, moral judgment, and person perception. The findings indicated that only perspective-taking ability was significantly related to aggressive behavior in delinquents. High-aggressive delinquents were less able to perceive others' viewpoints than were low-aggressive delinquents. These findings are consistent with previous research concerning perspective taking and aggression, but disconfirm research involving other social cognitive variables and aggression. Results further indicate the importance of studying social cognitive variables as they relate to relevant clinical behaviors.     

Do you think I’m as kind as I do? The relation of adolescent narcissism with self- and peer-perceptions of prosocial and aggressive behavior

The association between narcissism and aggression has been empirically supported in adults and adolescents, but it is unclear whether narcissism might also be related to prosocial behavior. The present study investigated this issue using self- and peer-informants. Participants were 183 adolescents ages 16–19 (159 males, 24 females; 64.5% Caucasian). Of these participants, 126 (104 males, 22 females) also had peer-reported data available. Self-reported pathological narcissism was positively correlated with self-reports of both prosocial behavior and aggression, but it was not associated with peer nominations of either type of behavior. These findings indicate that adolescents with high levels of narcissism may attempt to bolster their social status by reporting engagement in both prosocial behavior and aggression. However, it appears that such individuals are ineffective at being perceived as prosocial by peers.     

Attributional biases in aggressive children and their mothers

To investigate if mothers and their aggressive children share the tendency to infer hostile motives from others' behavior in ambiguous social situations, 100 pairs of mothers and their clinic-referred or comparison children (50 boys and 50 girls) were asked to interpret hypothetical situations involving both overtly and relationally provocative scenarios. Results replicated previous findings of studies on social information processing of aggressive children and extended the findings to mothers of aggressive children. Findings were generally consistent with the hypothesis that mothers of aggressive children tend to view others' ambiguous actions as hostile, increasing the probability of responding with aggression and, in effect, modeling a hostile attributional bias for their children. Examinations of mothers' and their children's attributional and behavioral intentions suggested that mothers' and daughters' attributions and behavioral intentions were significantly correlated, whereas mothers' and sons' were not. Gender effects with regard to provocation type are also discussed.     

Adolescent Narcissism,Aggression, and Prosocial Behavior: The Relevance of Socially Desirable Responding

An important threat to validity in personality research pertains to an individual's motivation to respond in a socially desirable manner on self-report inventories. This issue was examined in this study in the context of narcissism, aggression, and prosocial behavior in a sample of at-risk adolescents. Participants were 161 adolescents (128 males, 29 females, 4 not reported) ranging in age from 16 to 19 years who were attending a residential program for youth who have dropped out of school. Overall, socially desirable response tendencies were negatively correlated with vulnerable narcissism and self-reported aggression. Moreover, low socially desirable responses strengthened the relation between narcissism and self-reported aggression. Socially desirable responding was not associated with self- or peer-reported prosocial behavior and did not moderate the relation between narcissism and prosocial behavior. These findings indicate that the relation between narcissism and aggression is attenuated by concerns with social desirability. However, further work is needed in broader samples of adolescents to more closely examine whether social desirability concerns actually mitigate aggression among some youth or signify underreporting of one's problem behaviors.     

Criterion-related validity of the three-factor model of psychopathy: personality, behavior, and adaptive functioning

The Psychopathy Checklist-Revised (PCL-R) has been conceptualized as indexing two distinct but correlated factors. Previous research has established that these factors demonstrate distinct patterns of relations with external criteria. However, more recent findings suggest that the PCL-R psychopathy construct may encompass three distinguishable factors, reflecting affective, interpersonal, and behavioral symptoms. Here, we evaluated the validity of this newer three-factor model of the PCL-R factors with reference to external criteria from the domains of personality, antisocial behavior; and adaptive functioning in a sample of 310 incarcerated offenders. The interpersonal factor was related to social dominance, low stress reactivity, and higher adaptive functioning; the affective factor was correlated with low social closeness and violent offending; and the behavioral factor was associated with negative emotionality, disinhibition, reactive aggression, and poor adaptive functioning. These findings provide support for the convergent and discriminant validity of these psychopathy facets.     

Correlates of victimization in Chinese children's peer groups.

This study reports a cross-sectional investigation of the behavioral and academic correlates of victimization in Chinese children's peer groups. The participants were 296 children (161 boys and 135 girls; mean age = 11.5 years) from Tianjin, China. Multi-informant assessments (peer nominations, teacher ratings, and self-reports) of peer victimization, aggression, submissiveness-withdrawal, assertiveness-prosociability, and academic functioning were obtained. Structural equation models indicated that peer victimization was associated with poor academic functioning, submissive-withdrawn behavior, aggression, and low levels of assertive-prosocial behavior. These findings suggest that there is considerable similarity in the social processes underlying peer group victimization across Chinese and Western cultural settings.     

Individual and collective social cognitive influences on peer aggression: exploring the contribution of aggression efficacy, moral disengagement, and collective efficacy

This follow-up study with 1,167 primarily White adolescents (aged 13.45 years at T1, 613 females) examined the impact of self-efficacy for aggression, moral disengagement, and collective efficacy beliefs on peer aggression in schools. Students completed questionnaire measures at the beginning and end of the school year (8 months apart). High aggression efficacy and moral disengagement scores predicted higher frequency of peer aggression over time. Low collective efficacy beliefs regarding the ability of students and teachers to collaboratively act to inhibit peer aggression were also associated with more frequent aggression, although this association was stronger at higher levels of moral disengagement. The findings of this study highlight the need to consider collective efficacy beliefs in conjunction with individual social cognitive processes when seeking to explain aggressive behavior.
