Criminal thinking patterns, aggression styles, and the psychopathic traits of late high school bullies and bully-victims

This study explored the current psychological characteristics and criminal behavior history of individuals who retrospectively reported being bullies, bully-victims, victims, or controls (i.e. neither victims nor bullies) during their last 2 years of high school. College students (n = 960) completed measures of criminal thinking, aggression, psychopathy, and criminal behavior online. We predicted bullies and bully-victims would demonstrate the highest scores for criminal thinking, proactive aggression, psychopathy, and have the most criminal infractions. Bullies and bully-victims had significantly higher scores on criminal thinking, aggression, psychopathy, and criminal behaviors than victims or controls. Additionally, men were significantly higher in criminal thinking, aggression, psychopathy, and had more criminal acts than women. There were no gender by bully group interactions. Logistic regression analyses differentiated bully-victims from bullies. Bully-victims tended to be male, higher in criminal thinking, and higher in reactive aggression. In addition, bully-victims were distinct from victims, showing higher criminal thinking and higher proactive aggression.     

Gender symmetry in intimate aggression: an effect of intimacy or target sex?

Men's greater use of direct aggression is not evident in studies of intimate partner aggression. In previous research, the effects of target sex and relationship intimacy have frequently been confounded. This study sought to examine these effects separately. One hundred and seventy-four participants (59 male and 115 female) read vignette scenarios in which they were provoked by a same-sex best friend, an opposite-sex best friend, and a partner. For each target, participants estimated their likely use of direct physical and verbal aggression as well as noninjurious forms of anger expression. Results showed that men lower their aggression in the context of an intimate partnership and that this is an effect of the target's sex. In contrast, women raise their aggression in the context of an intimate partnership and this is an effect of intimacy with the target. The use of noninjurious angry behavior did not vary between targets for either sex of the participant, which suggests that the effects of target are confined to behaviors which carry an intention to harm. Possible effects of social norms and oxytocin-mediated emotional disinhibition on intimate partner aggression are discussed.     

No postnatal maternal effect on male aggressiveness in wild-derived strains of house mice

Male aggressiveness is a complex behavior influenced by a number of genetic and non-genetic factors. Traditionally, the contribution of each of these factors has been established from experiments using artificially selected strains for high/low aggressive phenotypes. However, little is known about the factors underlying aggressive behavior in natural populations. In this study, we assess the influence of genetic background vs. postnatal maternal environment using a set of cross-fostering experiments between two wild-derived inbred strains, displaying high (STRA, derived from Mus musculus domesticus) and low (BUSNA, derived from Mus musculus musculus) levels of aggressiveness. The role of maternal environment was tested in males with the same genetic background (i.e. strain origin) reared under three different conditions: unfostered (weaned by mother), infostered (weaned by an unfamiliar dam from the same strain), and cross-fostered (weaned by a dam from a different strain). All males were tested against non-aggressive opponents from the A/J inbred strain. Resource-holding potential was assessed through body weight gains and territory ownership. The STRA males were shown to be aggressive in both neutral cage and resident-intruder tests. On the contrary, the BUSNA males were less aggressive in all tests. We did not find a significant effect of postnatal maternal environment; however, we detected significant maternal effect on body weight with differences between the strains, fostering type and interactions between these factors. We conclude that the aggressiveness preserved in the two strains has significant genetic component whose genetic basis can be dissected by quantitative trait loci analysis.     

The incongruency advantage for environmental sounds presented in natural auditory scenes

The effect of context on the identification of common environmental sounds (e.g., dogs barking or cars honking) was tested by embedding them in familiar auditory background scenes (street ambience, restaurants). Initial results with subjects trained on both the scenes and the sounds to be identified showed a significant advantage of about five percentage points better accuracy for sounds that were contextually incongruous with the background scene (e.g., a rooster crowing in a hospital). Further studies with naive (untrained) listeners showed that this incongruency advantage (IA) is level-dependent: there is no advantage for incongruent sounds lower than a Sound/Scene ratio (So/Sc) of -7.5 dB, but there is about five percentage points better accuracy for sounds with greater So/Sc. Testing a new group of trained listeners on a larger corpus of sounds and scenes showed that the effect is robust and not confined to a specific stimulus set. Modeling using spectral-temporal measures showed that neither analyses based on acoustic features, nor semantic assessments of sound-scene congruency can account for this difference, indicating the IA is a complex effect, possibly arising from the sensitivity of the auditory system to new and unexpected events, under particular listening conditions.     

Eye movements and display change detection during reading

In the boundary change paradigm (Rayner, 1975), when a reader's eyes cross an invisible boundary location, a preview word is replaced by a target word. Readers are generally unaware of such changes due to saccadic suppression. However, some readers detect changes on a few trials and a small percentage of them detect many changes. Two experiments are reported in which we combined eye movement data with signal detection analyses to investigate display change detection. On each trial, readers had to indicate if they saw a display change in addition to reading for meaning. On half the trials the display change occurred during the saccade (immediate condition); on the other half, it was slowed by 15-25 ms (delay condition) to increase the likelihood that a change would be detected. Sentences were presented in an alternating case fashion allowing us to investigate the influence of both letter identity and case. In the immediate condition, change detection was higher when letters changed than when case changed corroborating findings that word processing utilizes abstract (case independent) letter identities. However, in the delay condition (where d' was much higher than the immediate condition), detection was equal for letter and case changes. The results of both experiments indicate that sensitivity to display changes was related to how close the eyes were to the invalid preview on the fixation prior to the display change, as well as the timing of the completion of this change relative to the start of the post-change fixation.     

Social curiosity and interpersonal perception: a judge x trait interaction

The present study examined the impact of social curiosity on the utilization of social information and the accuracy of personality judgments. In total, 182 individuals who never met each other before were asked to interact for 10 minutes and afterwards to evaluate the personality (Big Five) of their interaction partner. High socially curious judges were more accurate in evaluating the degree of Extraversion and Openness of their interaction partners. Interestingly, high and low curious judges differed significantly in the utilization of verbal and nonverbal cues displayed by their interaction partner. Specifically, high socially curious judges more often used valid cues for inferring Extraversion and Openness. No differences in interpersonal accuracy and cue utilization were found for Neuroticism, Conscientiousness, and Agreeableness. The results suggest that high socially curious individuals are more accurate in judging visible traits and that this higher accuracy is grounded in a more comprehensive utilization of valid cues.     

Adolescent political activism and long-term happiness: a 21-year longitudinal study on the development of micro- and macrosocial worries

Utilizing latent growth modeling, the long-term development of worries among peace movement supporters is examined. Data originate from a seven-wave German longitudinal study started in 1985 with on average 14-year-olds. Waves were interspersed 3 and a half years each. Activists are assumed to have lower (self-related) microworries (Hypothesis 1) and higher macroworries (concerned with larger entities; Hypothesis 2) than nonactivists at the onset of the study. Nonactivists who appraised the threat of nuclear war as high in 1985 are assumed to report worse mental health than their activist age-mates 21 years later (Hypothesis 3). Activists are assumed to express relatively more macroworries than nonactivists in midadulthood (Hypothesis 4). All four hypotheses were confirmed. Results are interpreted in a stress-coping (Lazarus) and resource (Elder) framework, suggesting that refraining from acting out against a perceived sociopolitical threat is a long-term risk for a positive mental health trajectory.     

How social is the social psychology of emotion?

Two classic studies published 50 years ago showed how other people provide information that shapes the activation and interpretation of emotions. The present paper traces development of the social psychology of emotions from this starting point. Subsequent research into group-based and social appraisal has advanced understanding of the impact of social information on emotions and suggested new ways of investigating associated phenomena. Although potential integrations of interpersonal and group-oriented approaches offer promise for the future, the continuing focus on emotions as cognitively mediated effects of social factors should broaden to encompass dynamic relational processes.     

Where do my emotions belong? A study of immigrants' emotional acculturation

The emotional experiences of people who live together tend to be similar; this is true not only for dyads and groups but also for cultures. It raises the question of whether immigrants' emotions become more similar to host culture patterns of emotional experience; do emotions acculturate? Two studies, on Korean immigrants in the United States (Study 1) and on Turkish immigrants in Belgium (Study 2), measured emotional experiences of immigrants and host group members with the Emotional Patterns Questionnaire. To obtain a measure of the immigrants' emotional similarity to the host group, their individual emotional patterns were correlated to the average pattern of the host group. Immigrants' exposure to and engagement in the host culture, but not their acculturation attitudes, predicted emotional acculturation.     

The evolution and psychology of self-deception

In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-enhancement also allows people to display more confidence than is warranted, which has a host of social advantages. The question then arises of how the self can be both deceiver and deceived. We propose that this is achieved through dissociations of mental processes, including conscious versus unconscious memories, conscious versus unconscious attitudes, and automatic versus controlled processes. Given the variety of methods for deceiving others, it should come as no surprise that self-deception manifests itself in a number of different psychological processes, and we discuss various types of self-deception. We then discuss the interpersonal versus intrapersonal nature of self-deception before considering the levels of consciousness at which the self can be deceived. Finally, we contrast our evolutionary approach to self-deception with current theories and debates in psychology and consider some of the costs associated with self-deception.
