Undergraduate Military Training and Measures of Aggression

Seventy-eight male undergraduates with ROTC training and 98 male undergraduates without ROTC training were compared in order to explore possible effects of education in aggressive expression and control. Utilized were inventories of aggression and guilt in addition to measures of aggressive mood, projection of aggression, and identification of aggressive percepts. Also assessed were changes following the presentation of a film intended to arouse justified anger. Several differences, not consistent in direction, were found between the groups on different measures, suggesting specificity of effects of training as well as distinctiveness of aspects of measured “aggression.”     

A Systematic Investigation of Gesture Kinematics in Evolving Manual Languages in the Lab

Silent gestures consist of complex multi-articulatory movements but are now primarily studied through categorical coding of the referential gesture content. The relation of categorical linguistic content with continuous kinematics is therefore poorly understood. Here, we reanalyzed the video data from a gestural evolution experiment (Motamedi, Schouwstra, Smith, Culbertson, & Kirby, 2019), which showed increases in the systematicity of gesture content over time. We applied computer vision techniques to quantify the kinematics of the original data. Our kinematic analyses demonstrated that gestures become more efficient and less complex in their kinematics over generations of learners. We further detect the systematicity of gesture form on the level of thegesture kinematic interrelations, which directly scales with the systematicity obtained on semantic coding of the gestures. Thus, from continuous kinematics alone, we can tap into linguistic aspects that were previously only approachable through categorical coding of meaning. Finally, going beyond issues of systematicity, we show how unique gesture kinematic dialects emerged over generations as isolated chains of participants gradually diverged over iterations from other chains. We, thereby, conclude that gestures can come to embody the linguistic system at the level of interrelationships between communicative tokens, which should calibrate our theories about form and linguistic content.     

Aggression Observation Scale for Group Psychotherapy: The Next Phase

An observational scale to record aggressive behaviors, defenses, and interventions that occur during a psychotherapy group has been developed. Content and process items are included. The content items focus on the spoken material and are on a continuum of increasing group members' awareness of and responsibility for their anger. The process items are directed to underlying psychodynamic issues on a continuum from avoiding anger, to indirect and then direct expression of anger. Leader interventions (responses) are also included. The development of the scale, the Aggression Observation Scale for Group Psychotherapy (AOSGP), is described, including pilot testing and beginning reliability and validity findings. Several years later further testing has been completed and is now reported.     

The Aggression Questionnaire: a validation study in student samples

The goal of this study was to examine the psychometric properties of the Aggression Questionnaire (AQ) in Spain. The AQ is a 29-item instrument designed to measure the different dimensions of the hostility/anger/aggression construct. It consists of 4 subscales that assess: (a) anger, (b) hostility, (c) verbal aggression, and (d) physical aggression. In Study 1, reliability, construct validity, and convergent validity were evaluated in a group of 384 male and female university students. Test-retest reliability was evaluated using a group of 154 male and female university students. The results of the factor analysis were similar to the scale structure claimed for this instrument. The subscales also showed internal consistency and stability over time. The AQ and its subscales were also compared with the scales and subscales of the Spielberger State-Trait Anger Expression Inventory (STAXI), the Cook-Medley Hostility Scale (Ho), the Buss-Durkee Hostility Inventory (BDHI), and the Jenkins Activity Survey-Form H (JASE-H). The results show that the AQ evaluates some aspects of anger, such as Anger-Trait and Anger-Out, rather than other elements, such as Anger-In or Anger-State. In Study 2, two new male groups were used to evaluate the criterion validity of the AQ: 57 prison inmates and 93 university students, finding that this instrument discriminated between the scores obtained by common offenders and university students.     

Perceptions and Punishments of Workplace Aggression: The Role of Aggression Content,Context, and Perceiver Variables1

Aggressiveness and sanctioning ratings made by 360 undergraduates to scenarios of workplace aggression suggest that aggressor gender, occupational status of aggressor relative to the target of aggression, and type of aggression content (i.e., hostility, obstructionism, or overt) affected these ratings. The results support hypothesized main effects for aggression content and aggressor gender, and also a significant interaction between occupational status and aggressor gender. However, the results failed to confirm hypotheses that perceiver variables (e.g., trait aggression) would add significantly to the prediction of either aggressiveness ratings or sanctioning ratings. Implications for policy formation to manage aggressive individuals in organizations are discussed.     

The Conditional Reasoning Measurement System for Aggression: An Overview

The Conditional Reasoning Measurement System is described. This procedure focuses on how people solve what on the surface appear to be inductive reasoning problems. The true intent of the problems is to determine if solutions based on implicit biases are logically attractive to a respondent. In this article, we focus on the types of implicit biases that underlie aggressive individuals' attempts to justify aggressive behavior. People who consistently select solutions based on these types of biases are scored as being potentially aggressive because they are cognitively prepared to rationalize aggression. Scores on the Conditional Reasoning Test for Aggression (CRT-A) have been shown to have acceptable psychometric properties and an average, uncorrected validity of .44 against behavorial criteria (in 10 studies).     

The relation between Rorschach signs of Aggression and behavioral Aggression in Emotionally Disturbed Boys

Ratings of aggressive behavior were related to Rorschach signs of aggression for sixty-three boys at a residential treatment school for children. The total list of 26 Rorschach signs was significantly correlated with the ratings, but much of this relationship was contributed by only a few individual signs. Indices of aggressive impulses, such as aggressive content, were not significant, while the more structural indices, considered as measures of impulse control, (presence of CF and absence of human movement responses), were significantly related to the behavior ratings. Presence or absence of human responses alone differentiated between low aggression and high aggression groups about as well as did a combination of indices.     

Socially Explosive Minds: The Triple Imbalance Hypothesis of Reactive Aggression

ABSTRACT The psychobiological basis of reactive aggression, a condition characterized by uncontrolled outbursts of socially violent behavior, is unclear. Nonetheless, several theoretical models have been proposed that may have complementary views about the psychobiological mechanisms involved. In this review, we attempt to unite these models and theorize further on the basis of recent data from psychological and neuroscientific research to propose a comprehensive neuro-evolutionary framework: The Triple Imbalance Hypothesis (TIH) of reactive aggression. According to this model, reactive aggression is essentially subcortically motivated by an imbalance in the levels of the steroid hormones cortisol and testosterone (Subcortical Imbalance Hypothesis). This imbalance not only sets a primal predisposition for social aggression, but also down-regulates cortical–subcortical communication (Cortical-Subcortical Imbalance Hypothesis), hence diminishing control by cortical regions that regulate socially aggressive inclinations. However, these bottom-up hormonally mediated imbalances can drive both instrumental and reactive social aggression. The TIH suggests that reactive aggression is differentiated from proactive aggression by low brain serotonergic function and that reactive aggression is associated with left-sided frontal brain asymmetry (Cortical Imbalance Hypothesis), especially observed when the individual is socially threatened or provoked. This triple biobehavioral imbalance mirrors an evolutionary relapse into violently aggressive motivational drives that are adaptive among many reptilian and mammalian species, but may have become socially maladaptive in modern humans.     

Aggression and Heat: The Mediating Role of Negative Affect1

Sixty-four undergraduate males received either very postive or very negative personal evaluations from an attitudinally similar or dissimilar stranger, and were then given an opportunity to aggress against this person by means of electric shock. Half were exposed to these stimuli under comfortably cool environmental conditions, while half were so treated under uncomfortably hot conditions. It was predicted that aggression toward the victim would increase as the degree of negative affect induced among subjects by the experimental conditions increased up to moderate levels, but that beyond this point, further increments in negative affect would actually tend to inhibit such behavior. A significant (p < .007) curvilinear relationship between negative affect and aggression supported these predictions, and suggested that such affect mediates the influence of high ambient temperatures on human aggression.     

The Harvard Pigeon Lab under Herrnstein

The history of the Harvard Pigeon Lab is a history of two periods of remarkable productivity, the first under Skinner's leadership and the second under Herrnstein's. In each period, graduate students flocked to the leader and then began stimulating one another. Chance favored Herrnstein's leadership, too, because an unusually large number of graduate students were admitted in the fall of 1962. In each period, productivity declined as the leader lost interest in the laboratory and withdrew. Directly and indirectly, the laboratory finally died as a result of the cognitive "revolution." Skinner and his students saw the possibility of a natural science of behavior and set about establishing that science based on concepts such as response rate, stimulus control, and schedules of reinforcement. Herrnstein and his students saw that the science could be quantitative and set about making it so, with relative response rate, the matching law, and the psychophysics of choice (analogous to S. S. Stevens' psychophysics). The history might provide a golden research opportunity for someone interested in the impact of such self-organizing research groups on the progress of science.     

The Rice Virtual Lab in Statistics

The Rice Virtual Laboratory in Statistics is an integrated combination of an electronic textbook, simulations/demonstrations, and case studies. The electronic textbook covers basic concepts in statistics and data analysis and contains links to data analysis tools, instructional demonstrations/simulations, and other on-line texts. The simulations and demonstrations help make abstract concepts concrete and allow students to investigate various aspects of statistical tests and distributions. Case studies demonstrate the real-world applicability of statistical methods. Materials are available on the World-Wide Web.     

Aggression: destructive and constructive aspects

The concept of aggression was long relegated to the shadow of the libido in psychoanalytic theory, placed among the negative affects by some theoreticians, denied the role of a primary drive among leading writers in clinical psychology, brought to the fore as an adaptive force in ethology, and proved to be a decisive factor in the development of psychosomatic ailments. The second part of the paper reviews experiments using projective techniques, showing that highly creative subjects as opposed to ones low in creativity seem inclined to accept their aggressive impulses. A total denial of these impulses has been typical of women with breast cancer.
