The moderating effect of trigger intensity on triggered displaced aggression

Many instances of aggression result in excessive retaliation in response to a seemingly trivial triggering event. The triggered displaced aggression paradigm (TDA; Miller, Pedersen, Earleywine, & Pollock, 2003) provides an experimental vehicle for exploring such occurrences. Participants were either provoked or not and were subsequently exposed to a neutral, mild, or moderately strong triggering event from a second bogus participant. Consistent with TDA theory (Miller et al., 2003), disjunctively escalated aggressive behavior occurred only among previously provoked participants when responding to the mild triggering event, but not the moderately strong or neutral trigger. Independent of provocation, the neutral triggering event elicited very low levels of aggression, whereas the moderately strong trigger elicited moderate levels of aggression. Implications for instances of real world aggression are discussed.     

The roles of ingroup identification and outgroup entitativity in intergroup retribution

A new aspect of intergroup conflict was investigated- vicarious retribution-in which neither the agent of retribution nor the target of retribution are directly involved in the initial intergroup provocation. The underlying processes involved in vicarious intergroup retribution were tested correlationally (Study 1) and experimentally (Study 2). Both ingroup identification and outgroup entitativity predict the degree of vicarious retribution. In both studies, there was evidence of motivated cognition, specifically that highly identified individuals perceived the outgroup as higher in entitativity than individuals low in identification. Structural equation modeling demonstrated that part of the effect of identification on retribution against the outgroup was mediated through perceptions of entitativity.     

Crossed categorization beyond the two-group model

Four studies examined processing of in-group and out-group information with stimuli that are more complex than those used in previous crossed categorization studies. A diverse set of predictions is generated by previous theoretical work to account for how participants will integrate information stemming from multiple group memberships. Heuristic, threshold-based processing of information was supported over algebraic processing. Participants appeared to divide stimuli into "in-grouplike" and "out-grouplike" metacategories. However, the threshold at which this distinction was made, and whether it was based on in-group favoritism or out-group derogation, was influenced by the nature of the situation and the task participants performed. Advantages of crossed categorization research that moves beyond the traditional two-group model are discussed.     

Using Force: Australian Newspaper Depictions of Contacts Between the Police and Persons Experiencing Mental Illness

The media creates and sustains knowledge about socially relevant issues such as crime, mental illness, and policing. Past research suggests that while the media portrayal of the police is undoubtedly complex, their portrayal of people experiencing mental illness remains mainly negative. The depiction of their encounters in the mass media is of considerable interest because of the influential role the media has on public opinion and debate; however, there is a lack of current research in this area. This study aimed to examine media items in the major newspapers across Australia between January 2006 and December 2007 (n = 77) to investigate their portrayal of this interface. The dominant themes encountered in the initial analysis depicted people experiencing mental illness as dangerous and a threat to the public, where the mental health system has failed to manage them adequately. Further analyses found that people experiencing mental illness were stigmatised in a third of the media items reviewed and were represented significantly more negatively in these encounters than the police. Implications of these findings and some suggestions regarding possible strategies that could improve socially responsible media reporting and public discourse on mental illness are proposed.     

Calories,beauty, and ovulation: The effects of the menstrual cycle on food and appearance-related consumption

The menstrual cycle has been largely ignored within the consumer research literature. Using a survey panel, women's food and appearance-related consumption was tracked for 35 consecutive days. As predicted, food-related desires, dollars spent, and eating behaviors were greater during the luteal (non-fertile) phase, whereas appearance-related desires, dollars spent, and beautification behaviors increased during the fertile phase. Dollars spent on products unrelated to food or beautification were not significantly influenced by the menstrual cycle. Hence, women's consumption desires, preferences, and dollars spent in evolutionarily relevant product categories (food and mating) fluctuate across their ovulatory cycle. Branding-related implications are briefly discussed.     

熟悉性对外群体同质性效应的影响

两个实验考查了年龄和性别群体中是否存在外群体同质性效应以及熟悉性对该种效应的影响。结果表明：1．年龄群体中存在明显的外群体同质性效应,这与青年群体和老年群体彼此不够熟悉有关;2．性别群体中不存在外群体同质性效应,这与青年男女群体彼此较为熟悉有关。     

Systematic changes in perceptual reactance induced by physical fitness training

The effect of life-change events on perceptual augmentation-reduction was studied in 72 subjects (40 men, 32 women). In three experiments the kinesthetic figural aftereffect was measured prior to and after either a physical fitness program, a course in yoga, or training in Transcendental Meditation. Each program lasted a minimum of 8 wk. Subjects completing fitness training, all of whom were initially classified as augmenters, became reducers by the end of their program. Subjects enrolled in yoga and meditation courses remained relatively stable in their perceptual tendencies.     

Sensed presence as a correlate of sleep paralysis distress, social anxiety and waking state social imagery

Isolated sleep paralysis (ISP) is a common parasomnia characterized by an inability to move or speak and often accompanied by hallucinations of a sensed presence nearby. Recent research has linked ISP, and sensed presence more particularly, with social anxiety and other psychopathologies. The present study used a large sample of respondents to an internet questionnaire (N=193) to test whether these associations are due to a general personality factor, affect distress, which is implicated in nightmare suffering and hypothesized to involve dysfunctional social imagery processes. A new measure, ISP distress, was examined in relation to features of ISP experiences, to self-reported psychopathological diagnosis, to scores on the Leibowitz Social Anxiety Scale and to scores on a new questionnaire subscale assessing social imagery in a variety of waking states. Three main results were found: (1) ISP experiences are only weakly associated with a prior diagnosis of mental disorder, (2) sensed presence during ISP is associated preferentially with ISP distress, and (3) ISP distress is associated with dysfunctional social imagery. A general predisposition to affective distress may influence the distress associated with ISP experiences; overly passive social imagery may, in turn, be implicated in this affect distress influence.
