The relationship between pain tolerance and trait aggression: effects of sex and gender role

The literature on pain and aggression has indicated that pain elicits aggression. However, research has generally examined pain as a situational variable and focused less on the dispositional ability of an individual to tolerate pain. The dearth of research on pain tolerance and aggression appears to contradict the existing theory on the aggression‐eliciting effect of pain, in that studies have found a positive relationship between pain tolerance and aggression. The purpose of this study was to determine whether the relationship between pain tolerance and aggression is moderated by sex and whether the positive relationship could be explained by masculine gender role conformity. A sample of 195 collegiate men and women completed trait measures and a laboratory assessment of pain tolerance. Results indicated that correlations between pain tolerance and trait aggression were significant and positive for men but not women. However, when men's conformity to masculine gender role was controlled for, the relationship between pain tolerance and trait aggression was nil and nonsignificant. Results are discussed in reference to socialization and maintenance of masculine status. Aggr. Behav. 35:422–429, 2009. © 2009 Wiley‐Liss, Inc.     

虚拟化身对攻击性的启动效应:游戏暴力性、玩家性别的影响

虚拟化身是个体在虚拟环境中的自我呈现,化身形象是与特定刻板印象相联系的虚拟化身的外在表象。虚拟化身与攻击性的关系已得到证实,但还有一些问题尚需探讨。本研究通过2个实验,采用线索启动的方法,考察了化身形象、游戏暴力性和玩家性别对化身认同和攻击性的影响,以及化身认同和攻击性之间的关系。实验1结果表明:化身形象与游戏暴力性交互影响化身认同和攻击性。在暴力游戏中,化身形象对化身认同和攻击性有显著影响;在非暴力游戏中,化身形象对化身认同的影响边缘显著,但对攻击性无显著影响。对不同化身形象的认同会诱发不同的攻击性,但受游戏暴力性的影响。实验2结果表明:在暴力游戏中,化身形象与玩家性别交互影响化身认同和攻击性。女性在化身认同方面比男性更易受化身形象影响;男性在攻击性方面比女性更易受化身形象影响。对不同化身形象的认同会导致不同的攻击性,但受性别的影响。     

Relationship of Prosody Perception to Personality and Aggression

One-hundred-fifteen participants (73 female, 42 male) were evaluated for prosody, or vocal emotion, perception, personality factors, relational aggression and physical aggression. The male participants reported higher levels of physical aggression, and the female participants reported greater Neuroticism, consistent with other data. For the male participants, better perception of prosody was related to both greater Extraversion and greater Conscientiousness, all involved in interpersonal functioning. These relationships were not found in the female participants, but there was a relationship between perception of prosody and relational aggression. Women who were better at perceiving the emotional status of others based on vocal cues were less relationally aggressive. Perhaps greater relational aggression reflects a poor adaptation to diminished ability to perceive emotional status.     

Differences in high and low anxiety sensitive women's responses to a laboratory-based cold pressor task

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain-related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16-item measure of AS. Participants were tested individually on a lab-based cold pressor task using a variety of self-report and observer-measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire-Short Form (SF-MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF-MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain-related fear as a mediating variable between AS and increased perceived pain intensity.     

Differences in High and Low Anxiety Sensitive Women's Responses to a Laboratory‐Based Cold Pressor Task

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain‐related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16‐item measure of AS. Participants were tested individually on a lab‐based cold pressor task using a variety of self‐report and observer‐measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire – Short Form (SF‐MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF‐MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain‐related fear as a mediating variable between AS and increased perceived pain intensity.     

Emotional flexibility and recovery from pain

This study aimed to investigate the relationship between two aspects of emotional flexibility (EF, i.e. flexible emotional responsiveness and affective flexibility) and tolerance for, and recovery from, experimentally-induced pain. Fifty-two adults completed a flexible emotional responsiveness task in which emotional responses on multiple dimensions were registered while watching positive and negative pictures. Affective flexibility was measured using a switching task with positive and negative pictures. Pain tolerance was assessed as the time participants endured an ischemic pain task and total time until recovery in terms of pain intensity and pain unpleasantness was registered. Flexible emotional responsiveness—reflected in divergent corrugator responses to positive and negative stimuli—was associated with faster recovery from pain unpleasantness. Affective flexibility was associated with recovery in terms of pain intensity, with faster switches from neutral towards affective aspects of positive stimuli being predictive of faster recovery. Results did not provide evidence for an association between EF and pain tolerance. The findings suggest that EF may protect against pain persistence.

     

Pain expectation,negative affect,and angry aggression

An experiment was conducted to determine if the relatively strong negative affect generated by anticipation of pain from exposure to aversive stimulation would give rise to an instigation to aggression and accompanying feelings of annoyance-irritation-anger. The 45 undergraduate women in the study were required to immerse their nondominant hand in water as they administered reward and punishment to a fellow student, supposedly as an evaluation of that person's solutions to assigned problems. In two-thirds of the cases the water temperature was unpleasantly cold, while it was much more tolerable in temperature for the remaining subjects. Half of the participants in the cold water condition and all of those in the more tolerable water temperature group has been led to expect the possibility of pain as they kept their hand in the water, whereas the remaining women (exposed to the cold water) had been alerted only to the physical sensations they would have. In accord with the findings obtained in an earlier experiment by Leventhal, Brown, Sacham, and Enquist (1979), the subjects in the cold water group expecting that they might feel pain reported experiencing the greatest discomfort. Further, consistent with Berkowitz's analysis of anger and angry aggression, these participants also reported the strongest feelings of annoyance-irritation-anger and were most punitive to the available target even though they could not attribute their discomfort to this person.     

Interactive Links Between Theory of Mind,Peer Victimization,and Reactive and Proactive Aggression

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.     

Religious Activities, Religious Orientation, and Aggressive Behavior

Theorists and clinicians have long believed that religious practice may reduce aggression and other destructive behaviors. To date, most evidence for a relationship between religiosity and aggression comes from nonexperimental studies. The purpose of this exploratory study was twofold. First, to examine experimentally whether two religious practices reduce aggressive behavior; second, to determine if specific aspects of religious orientation and spiritual transcendence are related to level of aggression, expressed under controlled laboratory conditions. Sixty-two participants assigned to one of three experimental groups (memorize Bible passages, prayer/meditation, or control group) completed a laboratory task of aggression. Participants also completed religious and spirituality instruments, along with self-ratings of aggressive disposition. Results indicated that neither memorization of biblical passages nor meditation reduced aggression. Intrinsic-oriented religiosity participants self-reported lower aggression than extrinsic-oriented participants, but no differences were found on the laboratory task of aggression. Spiritual transcendence showed no behavioral aggression differences .     

情绪如何引发暴力犯的攻击?基于情绪调节理论的解释

本文基于情绪调节理论, 以暴力犯为被试, 通过2项研究探究了情绪在攻击产生过程中的作用。研究1采用改编的反应时竞争范式测量个体攻击行为。结果发现, 情绪调节动机在负性情绪与攻击间起完全中介作用, 证实了负面情绪状态下, 暴力犯会为了调节情绪而实施攻击。研究2进一步表明, 攻击的确能起到调节情绪的作用。具体来说, 在暴力犯群体中, 实施反应性攻击之后, 会伴随着正性情绪的提升和负性情绪的下降; 实施主动性攻击之后, 个体的正性情绪和负性情绪都会提升。文章从对攻击结果的预期和攻击的实际效果两个角度, 对攻击的情绪调节理论进行了验证, 为情绪在攻击产生过程中的作用提出了新的解释。今后的研究和实践过程中, 应设法避免个体通过攻击调节情绪, 引导其使用合理的方式调节情绪以减少攻击行为的产生。     

Beyond the aggregate score: Using multilevel modeling to examine trajectories of laboratory-measured aggression

Aggression is often measured in the laboratory as an iterative “tit-for-tat” sequence, in which two aggressors repeatedly inflict retaliatory harm upon each other. Aggression researchers typically quantify aggression by aggregating across participants’ aggressive behavior on such iterative encounters. However, this “aggregate approach” cannot capture trajectories of aggression across the iterative encounters and needlessly eliminates rich information in the form of within-participant variability. As an alternative approach, I used multilevel modeling (MLM) to examine the slope of aggression across the 25-trial Taylor Aggression Paradigm as a function of trait physical aggression and experimental provocation. Across two preregistered studies (combined N = 392), participants exhibited a modest decline in aggression. This decline reflected a reciprocal strategy, in which participants responded to an initially-provocative opponent with greater aggression that then decreased over time to match their opponent's declining levels of aggression. Against predictions, trait physical aggression and experimental provocation did not affect participants’ overall trajectories of aggression. Yet, exploratory analyses suggested that the participants’ tendency to reciprocate their opponent's aggression with more aggression was greater at higher levels of trait physical aggression and attenuated among participants who had already been experimentally provoked by their opponent. These findings (a) illustrate several advantages of an MLM approach as compared with an aggregate approach to iterative laboratory aggression paradigms; (b) demonstrate that the magnifying effects of trait aggression and experimental provocation on laboratory aggression are stable over brief time-frames; and (c) suggest that modeling the opponent's behavior on such tasks reveals important information.     

Overt and relational aggression and perceived popularity: developmental differences in concurrent and prospective relations

Relations of overt and relational aggression with perceived popularity among children and early adolescents were examined in 2 studies (Ns = 607 and 1,049). Among older youths, positive concurrent relations found between overt aggression and perceived popularity became nonsignificant when relational aggression was controlled, whereas positive associations found between relational aggression and perceived popularity held when overt aggression was controlled. Aggression and perceived popularity were not positively related for the younger participants. The 2nd study also examined the temporal ordering of these relations over 6 months. For older girls, positive relations between relational aggression and perceived popularity were bidirectional. For older boys, relational aggression did not predict increased perceived popularity, but perceived popularity predicted increased relational aggression. Implications for intervention are discussed.     

Attenuating the link between threatened egotism and aggression

Research has found that narcissists behave aggressively when they receive a blow to their ego. The current studies examined whether narcissistic aggression could be reduced by inducing a unit relation between the target of aggression and the aggressor. Experimental participants were told that they shared either a birthday (Study 1) or a fingerprint type (Study 2) with a partner. Control participants were not given any information indicating similarity to their partner. Before aggression was measured, the partners criticized essays written by the participants. Aggression was measured by allowing participants to give their partner loud blasts of noise through a pair of headphones. In the control groups, narcissists were especially aggressive toward their partner. However, narcissistic aggression was completely attenuated, even under ego threat, when participants believed they shared a key similarity with their partner.     

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.     

Microaggressions Are a Form of Aggression

Most efforts to understand microaggressions have examined affected group members, but little work has been done to understand the motivations and characteristics of offenders. The purpose of this study was to determine whether microaggressions are best conceptualized as a form of aggression, as per common definitions advanced in social psychology, by examining correlations between propensity to commit microaggressions and aggressive tendencies. This cross-sectional study was conducted using MTurk Prime to survey a sample of White and Black adults across the United States (N = 610). Measures administered included the Cultural Cognitions and Actions Scale (CCAS) to assess the likelihood of committing microaggressions, Buss–Perry Aggression Questionnaire (BPAQ), Inventory of Hostility and Suspicious Thinking (IHS), Overt–Covert Aggression Inventory (OCAI), and the Positive and Negative Affectivity Schedule (PANAS). The CCAS was found to be highly and significantly positively correlated with all three measures of aggression. There was a significant negative correlation between Black participants’ ratings of microaggressive interactions being racist and White participants’ likelihood of engaging in those same interactions. There was a significant positive correlation between negative affectivity and the propensity of White participants to commit microaggressions. In a regression predicting microaggressive propensity from aggressive tendencies, the BPAQ was highly significant, whereas negative affectivity was not. Findings indicate that microaggressions represent aggression and hostility on the part of offenders and a form of aggressive behavior that is generally socially unacceptable. Future research should explore the relationship between the many forms of microaggressions and aggression among different groups.     

The neural correlates of alcohol-related aggression

Alcohol intoxication is implicated in approximately half of all violent crimes. Over the past several decades, numerous theories have been proposed to account for the influence of alcohol on aggression. Nearly all of these theories imply that altered functioning in the prefrontal cortex is a proximal cause. In the present functional magnetic resonance imaging (fMRI) experiment, 50 healthy young men consumed either a low dose of alcohol or a placebo and completed an aggression paradigm against provocative and nonprovocative opponents. Provocation did not affect neural responses. However, relative to sober participants, during acts of aggression, intoxicated participants showed decreased activity in the prefrontal cortex, caudate, and ventral striatum, but heightened activation in the hippocampus. Among intoxicated participants, but not among sober participants, aggressive behavior was positively correlated with activation in the medial and dorsolateral prefrontal cortex. These results support theories that posit a role for prefrontal cortical dysfunction as an important factor in intoxicated aggression.     

The moderating effect of trivial triggering provocation on displaced aggression

Two studies examined the interaction between the presence or absence of (a) an initial provocation and (b) a subsequent minor triggering action on the part of the target of displaced aggression. Consistent with the triggering event being seen by participants as indeed trivial when administered by itself without prior provocation, exposure to it literally had no impact on aggression toward its source. When previously provoked, however, this subsequent triggering event strongly increased displaced aggression, causing it to reliably exceed both that displayed when there was no antecedent provocation and that elicited by provocation alone. Mediation analyses showed that for participants who had been provoked, subjective feelings of displeasure concerning the triggering event mediated the effect of the trigger on aggression.     

The Relationship Between Direct Violence Victimization and Arrest History: The Mediating Role of Aggression

This study sought to determine whether emerging adults with a history of arrest differed on reported experiences of direct violence victimization (DVV), as well as measures of depression, posttraumatic stress disorder, and aggression. We administered self-report measures to 535 diverse college students. Results revealed that 64 participants reported a history of arrest. Participants with a history of arrest reported significantly higher scores on measures of aggression, as well as a greater number of DVV experiences, when compared to a comparable random sample of participants with no history of arrest. When the total sample was examined, there was no direct relationship between DVV and history of arrest. However, we found evidence for the mediating effect of aggression between the two variables. Our findings suggest that, among emerging adults who have experienced DVV, high levels of aggression may play a role in criminal justice involvement.
