Trait Aggressiveness and Situational Provocation: A Test of the Traits as Situational Sensitivities (TASS) Model

Human aggression in everyday life: An empirical test of the general aggression model

With the general aggression model (GAM), Anderson and Bushman (2002) provided an integrative framework to explain the complex nature of aggression. Based on the GAM, we examined whether personological and situational factors (interactively) have an impact on the person's internal state (consisting of aggressive cognition, affect, and physiological arousal), which in turn is assumed to lead to aggressive behaviour. In a large-scale experience sampling study, 403 participants answered 7558 questionnaires over a period of 2 weeks. As hypothesized, participants were more likely to exhibit an aggressive internal state the higher they scored on antagonistic personality traits (trait aggression, narcissism, psychopathy, sadism, anger rumination) and the more interpersonal, intrapersonal, and environmental triggers they experienced. Aggressive behaviour was positively related to trait aggression, psychopathy, sadism, anger rumination, and all situational triggers. Furthermore, the impact of antagonistic personality traits and situational triggers on aggressive behaviour was considerably reduced when the aggressive internal state was taken into account. Contrary to predictions, the relationship between antagonistic personality traits and the aggressive internal state was most pronounced when situational triggers were low. Overall, however, the process by which personal and situational variables predict aggression in daily life can be well explained by the GAM.

Using citation network analysis to enhance scholarship in psychological science: A case study of the human aggression literature

Researchers cannot keep up with the volume of articles being published each year. In order to develop adequate expertise in a given field of study, students and early career scientists must be strategic in what they decide to read. Here we propose using citation network analysis to characterize the literature topology of a given area. We used the human aggression literature as our example. Our citation network analysis identified 15 research communities on aggression. The five largest communities were: “media and video games”, “stress, traits and aggression”, “rumination and displaced aggression”, “role of testosterone”, and “social aggression”. We examined the growth of these research communities over time, and we used graph theoretic approaches to identify the most influential papers within each community and the “bridging” articles that linked distinct communities to one another. Finally, we also examined whether our citation network analysis would help mitigate gender bias relative to focusing on total citation counts. The percentage of articles with women first authors doubled when identifying influential articles by community structure versus citation count. Our approach of characterizing literature topologies using citation network analysis may provide a valuable resource for psychological scientists by outlining research communities and their growth over time, identifying influential papers within each community (including bridging papers), and providing opportunities to increase gender equity in the field.

Cellphone addiction during the Covid-19 outbreak: How online social anxiety and cyber danger belief mediate the influence of personality

The highly contagious Covid-19 virus is spreading around the world, and quarantining at home has become one of the main preventative behaviors, but it has also led to news blackouts, affecting people's normal life and interactions. In order to determine a predictor of cellphone addiction (CPA), the present study, based on the Risk of Information Seeking and Processing (RISP) model, investigated the relationship between personality (Neuroticism and Extraversion) and CPA during the epidemic, mediated by online social anxiety (OSA) and cyber danger belief (CDB). A total of 683 questionnaires were collected through snowball sampling and analyzed by Mplus. Results indicated that neurotic and extroverted individuals developed CPA through different mediating factors. Neuroticism affected CPA through OSA while Extraversion affected CPA through CDB. These findings highlight the importance of different mechanisms of individuals with different personalities. Corresponding cognitive treatments on the perception of social anxiety and cyber danger are recommended on neurotic and extroverted individuals, respectively, in order to reduce their degree of CPA.

The Role of Personality in Shaping Pandemic Response: Systemic Sociopolitical Factors Drive Country Differences

The current study utilizes the current COVID-19 pandemic to highlight the importance of accounting for the influence of external political and economic factors in personality public health research. We investigated the extent to which systemic factors modify the relationship between personality and pandemic response. Results shed doubt on the cross-cultural generalizability of common Big Five factor models. Individual differences only predicted government compliance in autocratic countries and in countries with income inequality. Personality was only predictive of mental health outcomes under conditions of state fragility. Our ability to use individual differences to understand policy-relevant outcomes changes based on environmental factors and must be assessed on a trait-by-trait basis, thus supporting the inclusion of systemic political and economic factors in individual differences models.

Justice Sensitivity and the Processing of Justice–Related Information

We investigated how Justice Sensitivity (JS) shapes the processing of justice–related information. We proposed that due to frequently perceiving and ruminating about injustices, persons high in JS develop highly accessible and differentiated injustice concepts that shape attention, interpretation and memory for justice–related information. Three studies provided evidence for these assumptions. After witnessing injustice, persons high in JS attended more strongly to unjust stimuli than to negative control stimuli (Study1) and interpreted an ambiguous situation as less just than persons low in JS (Study2). Finally, they displayed a memory advantage for unjust information (Study3). Results suggest that JS involves the availability and accessibility of injustice concepts as parameters of cognitive functioning and offer explanations for effects of JS on justice–related behaviour.

Is It Personal? Context Moderates BPD Effects on Spontaneous Rumination and Distress

Borderline personality disorder (BPD) is associated with the use of maladaptive emotion regulation (ER) that predicts unstable interpersonal relationships and emotion dysregulation. Rumination, a maladaptive cognitive ER response, may be one mechanism by which those with BPD experience emotion dysregulation. However, it remains unclear whether emotion dysregulation is linked to rumination in general, or to rumination during interpersonal situations that often prove challenging for those with BPD. The present study examined whether interpersonal exclusion conferred an increased risk to spontaneously ruminate among those with elevated BPD features relative to an impersonal negative mood induction, and whether spontaneous rumination mediated the effects of BPD features on distress reactivity. Overall, BPD features predicted stronger tendencies to spontaneously ruminate and higher levels of distress following interpersonal exclusion; spontaneous rumination following interpersonal exclusion mediated the effects of BPD features on distress. These findings highlight the importance of context when examining ER outcomes.

Effects of cartoon violence on aggressive thoughts and aggressive behaviors

This article reports on an experiment designed to test whether the cartoon manipulation leads to significant increases in aggressive thoughts and aggressive behaviors among Chinese children (n = 3,000). Results indicated that brief exposure to a violent cartoon triggered higher aggressive thoughts and aggressive behaviors than a nonviolent cartoon. Females displayed higher aggressive thoughts and aggressive behaviors than males in a nonviolent cartoon condition, while males displayed higher aggressive behaviors than females in a violent cartoon condition. Mediation analysis suggested that the effect on aggressive behaviors was mediated by aggressive thoughts. The findings imply that cartoon developers, parents, and teachers should develop cartoons that inhibit children's aggressive thoughts to avoid aggressive behaviors. Females are the key group for the prevention and intervention of aggression in a nonviolent cartoon context, while males are the key group for the prevention and intervention of aggression in a violent cartoon context.

Trait aggressiveness predicting aggressive behavior: The moderating role of meta-cognitive certainty

Research on aggression has benefitted from using individual-difference measures to predict aggressive behavior. Research on meta-cognition has recently identified that the predictive utility of individual-difference inventories can be improved by considering the certainty with which people hold their self-views. Merging these two frameworks, the present research examines whether assessing certainty in trait aggressiveness improves its ability to predict aggressive outcomes. Across two studies, participants reported their level of trait physical aggressiveness and the certainty with which they held their responses to the scale (predictor variables). Aggressive behavioral intentions (Study 1 and 2) and actual aggressive behavior (Study 2) were used as dependent measures. As hypothesized, results indicated that certainty moderated the effects of individual-differences in aggressiveness on both aggressive outcomes. Therefore, considering the certainty with which people hold their relevant traits can be useful for understanding aggression, and also for predicting the consistency between personality and behavior.

The role of the right temporo-parietal junction in social decision-making

Identifying someone else's noncooperative intentions can prevent exploitation in social interactions. Hence, the inference of another person's mental state might be most pronounced in order to improve social decision-making. Here, we tested the hypothesis that brain regions associated with Theory of Mind (ToM), particularly the right temporo-parietal junction (rTPJ), show higher neural responses when interacting with a selfish person and that the rTPJ-activity as well as cooperative tendencies will change over time. We used functional magnetic resonance imaging (fMRI) and a modified prisoner's dilemma game in which 20 participants interacted with three fictive playing partners who behaved according to stable strategies either competitively, cooperatively or randomly during seven interaction blocks. The rTPJ and the posterior-medial prefrontal cortex showed higher activity during the interaction with a competitive compared with a cooperative playing partner. Only the rTPJ showed a high response during an early interaction phase, which preceded participants increase in defective decisions. Enhanced functional connectivity between the rTPJ and the left hippocampus suggests that social cognition and learning processes co-occur when behavioral adaptation seems beneficial.

The curvilinear relationship between work pressure and momentary task performance: the role of state and trait core self-evaluations

Whereas several studies have demonstrated that core self-evaluations (CSE)–or one’s appraisals about one’s own self-worth, capabilities, and competences–relate to job outcomes, less is known about the mechanisms underlying these relationships. In the present study, we address this issue by examining the role of within- and between-person variation in CSE in the relationship between work pressure and task performance. We hypothesized that (a) work pressure relates to task performance in a curvilinear way, (b) state CSE mediates the curvilinear relationship between work pressure and task performance, and (c) the relationship between work pressure and state CSE is moderated by trait CSE. Our hypotheses were tested via a 10-day daily diary study with 55 employees in which trait CSE was measured at baseline, while work pressure, task performance, and state CSE were assessed on a daily basis. Bayesian multilevel path analysis showed that work pressure affects task performance via state CSE, with state CSE increasing as long as the employee feels that (s)he is able to handle the work pressure, while it decreases when the level of work pressure exceeds the employees’ coping abilities. Moreover, we found that for people low on trait CSE, the depleting effect of work pressure via state CSE happens for low levels of work pressure, while for people high in trait CSE the depleting effect is located at high levels of work pressure. Together, our findings suggest that the impact of work pressure on task performance is driven by a complex interplay of between- and within-person differences in CSE.

The cognitive-behavioral system of leadership: cognitive antecedents of active and passive leadership behaviors

In the present paper, we propose a cognitive-behavioral understanding of active and passive leadership. Building on core evaluations theory, we offer a model that explains the emergence of leaders' active and passive behaviors, thereby predicting stable, inter-individual, as well as variable, intra-individual differences in both types of leadership behavior. We explain leaders' stable behavioral tendencies by their fundamental beliefs about themselves, others, and the world (core evaluations), while their variable, momentary behaviors are explained by the leaders' momentary appraisals of themselves, others, and the world (specific evaluations). By introducing interactions between the situation the leader enters, the leader's beliefs, appraisals, and behavior, we propose a comprehensive system of cognitive mechanisms that underlie active and passive leadership behavior.

Trait aggression in two representative U.S. surveys: Testing the generalizability of college samples

Aggression research often relies upon convenient samples with unknown generalizability to populations of interest, potentially threatening external validity. This article details the measurement properties of the Buss-Perry Aggression Questionnaire Short Form (BPAQ-SF) and its subscales in two nationally representative U.S. samples (N = 924) and a concurrent study with U.S. college students (N = 384). The results provide useful benchmarks for generalizing BPAQ-SF results from convenient samples to U.S. adults, including distributions, reliability, and factor structure. The results also confirm basic relationships between trait aggression and key social and demographic variables such as sex, age, and socioeconomic status while establishing convergent validity with violent political attitudes. Results from the national studies closely align with those from the student sample, providing reasonable support for generalizing trait aggression elements to U.S. adults. Aggr. Behav. Aggr.

Brief mindfulness induction could reduce aggression after depletion

Many experiments have shown that one's ability to refrain from acting on aggressive impulses is likely to decrease following a prior act of self-control. This temporary state of self-control failure is known as ego-depletion. Although mindfulness is increasingly used to treat and manage aggressive behaviour, the extent to which mindfulness may counteract the depletion effect on aggression is yet to be determined. This study (N=110) investigated the effect of a laboratory induced one-time mindfulness meditation session on aggression following depletion. Aggression was assessed by the intensity of aversive noise blast participants delivered to an opponent on a computerised task. Depleted participants who received mindfulness induction behaved less aggressively than depleted participants with no mindfulness induction. Mindfulness also improved performance on a second measure of self-control (i.e., handgrip perseverance); however, this effect was independent of depletion condition. Motivational factors may help explain the dynamics of mindfulness, self-control, and aggression.

The Asymmetric Behavioral Homeostasis Hypothesis: Unidirectional Flexibility of Fundamental Motivational Processes

Natural selection has produced not only fixed adaptive traits in response to enduring environments, but also contingencies capable of yielding variable outcomes in variable environments. A well-known example is phenotypic plasticity, which entails alternative developmental outcomes in different environments. Here, we focus on more immediate and transitory behavioral plasticity (underpinned by motivational processes), and we suggest that the physiological concept of homeostasis offers a coherent perspective for studying human motivations and associated behavioral processes. We further propose the asymmetric behavioral homeostasis hypothesis, which conceptualizes many motivational processes as 1-sided homeostatic mechanisms and which predicts that motivational responses that are amplified by certain cues will not be reversed simply by reversing the input cues. An important implication is that many evolutionarily adaptive—albeit subjectively and socially deleterious—responses to fitness threats (e.g., fears, aversions) are more easily inflamed than dampened. We review literature bearing on this hypothesis and discuss implications for psychology.

Proposal of a Nonlinear Interaction of Person and Situation (NIPS) model

Marshall and Brown (2006) proposed a Traits as Situational Sensitivities (TASS) Model, which implies a systematic person × situation interaction. We review this model and show that it suffers from several limitations. We extend and modify the model in order to obtain a symmetric pattern of levels and effects for both person and situation factors. Our suggestions result in a general Nonlinear Interaction of Person and Situation (NIPS) Model. The NIPS model bears striking similarities to the Rasch model. Based on the symmetric nature of the NIPS model, we generalize the concept of weak and strong situations to individuals and propose the concepts of weak and strong persons. Finally, we discuss psychological mechanisms that might explain the NIPS pattern and offer ideas for future research.

Fear of crime in old age: precautious behaviour and its relation to situational fear

This study aimed to provide further insight into the question of why older adults show a higher precautionary behaviour regarding crime (behavioural fear), although they do not estimate their victimisation risk as higher than young adults and they do not experience fear more often. In two cross-sectional studies, the hypothesis was tested that the age-related increase in precautionary behaviour is an expression of higher dispositional fear with age. The vignette technique was employed to induce situational fear of crime across various situations as a proxy for dispositional fear. In contrast to the hypothesis, in Study 1 (young: 18-30 years, N = 179 vs. middle-aged: 50-64 years, N = 106), only younger adults reported higher situational fear in two vignettes. In Study 2 (young: 18-30 years, N = 129 vs. young-old: 65-84 years, N = 114), younger adults indicated higher situational fear again; however, young-old adults reported higher situational fear in other vignettes. The findings suggest that there is no general increase in the intensity of situational fear of crime with age and thus no age-related change in dispositional fear. Moreover, situational fear did not serve as mediator in the relationship between age and precautionary behaviour. Alternative accounts for the increase in behavioural fear of crime are discussed as well as emotion regulation mechanisms in response to the induction method.

The Strong Situation Hypothesis

A conventional wisdom in personality and social psychology and organizational behavior is that personality matters most in weak situations and least in strong situations. The authors trace the origins of this claim and examine the evidence for the personality-dampening effect of strong situations. The authors identify the gap between claim and evidence and suggest an agenda for future research.
