Omega-3 supplements reduce self-reported physical aggression in healthy adults.

There is emerging evidence that Omega-3 polyunsaturated fatty acids (PUFA) supplements can decrease aggression. However, experimental studies with adults from non-specific populations are scarce. We hypothesized that Omega-3 supplements would decrease self-reported aggression among non-clinical participants.

Dynamic Exposure to Alcohol Advertising in a Sports Context Influences Implicit Attitudes.

Background: Experimental studies investigating the impact of advertising with ecological stimuli on alcohol-related cognition are scarce. This research investigated the cognitive processes involved in learning implicit attitudes toward alcohol after incidental exposure to alcohol advertisements presented in a dynamic context. We hypothesized that incidental exposure to a specific alcohol brand would lead to heightened positive implicit attitudes toward alcohol due to a mere exposure effect.

Intimate partner aggression-related shame and posttraumatic stress disorder symptoms: The moderating role of substance use problems.

A dearth of literature has examined the consequences of women's use of aggression in intimate relationships. Women's use of aggression against their intimate partners, regardless of their motivation (e.g.

The underlying role of posttraumatic stress disorder symptoms in the association between intimate partner violence and deliberate self-harm among African American women.

African American women are at heightened risk for intimate partner violence (IPV) and its negative consequences, including health-compromising behaviors. Deliberate self-harm (DSH) is one clinically-relevant behavior that has been understudied among African American women generally and those with exposure to IPV in particular. To date, no studies have examined factors that may account for the relationship between IPV and DSH.

Some like it hot: testosterone predicts laboratory eating behavior of spicy food.

In the present study, we analyzed the relationship between eating behavior of spicy food and endogenous testosterone. Participants included 114 males between the ages of 18 and 44 recruited from the community. They were asked to indicate their preferences regarding spicy food and were then asked to season a sample of mashed potatoes with pepper sauce and salt (control substance) prior to evaluating the spiciness of the meal.

The drunk utilitarian: blood alcohol concentration predicts utilitarian responses in moral dilemmas.

The hypothetical moral dilemma known as the trolley problem has become a methodological cornerstone in the psychological study of moral reasoning and yet, there remains considerable debate as to the meaning of utilitarian responding in these scenarios. It is unclear whether utilitarian responding results primarily from increased deliberative reasoning capacity or from decreased aversion to harming others. In order to clarify this question, we conducted two field studies to examine the effects of alcohol intoxication on utilitarian responding.

Probable posttraumatic stress disorder and women's use of aggression in intimate relationships: the moderating role of alcohol dependence.

Posttraumatic stress disorder (PTSD) is highly prevalent among individuals who experience intimate partner violence (IPV) and is associated with aggression in intimate relationships. The present study examined whether alcohol dependence (AD) attenuates the relation between PTSD and IPV-victimized women's use of physical, psychological, and sexual aggression. Participants were recruited from the community and included 147 women who engaged in substance use and experienced IPV (80.

Personality predicts obedience in a Milgram paradigm.

This study investigates how obedience in a Milgram-like experiment is predicted by interindividual differences. Participants were 35 males and 31 females aged 26-54 from the general population who were contacted by phone 8 months after their participation in a study transposing Milgram's obedience paradigm to the context of a fake television game show. Interviews were presented as opinion polls with no stated ties to the earlier experiment.

Evidence for a curvilinear dose-response relationship between avoidance coping and drug use problems among women who experience intimate partner violence.

Women who experience intimate partner violence (IPV) are at heightened risk for drug use problems. While prevailing models of drug use suggest that IPV-exposed women use drugs in an effort to escape or avoid negative affect, a dearth of literature has examined the role of avoidance coping in drug use problems within this population. Given recent suggestions that flexible, situationally appropriate use of avoidance coping may be adaptive, particularly when confronted with highly stressful situations, we hypothesized that avoidance coping and drug use problems would demonstrate a curvilinear, U-shaped dose-response relationship.

Anxiolytic-like effects observed in rats exposed to the elevated zero-maze following treatment with 5-HT2/5-HT3/5-HT4 ligands.

The present study examined the effects of administering selective 5-HT antagonists and agonists to rats tested in the elevated zero-maze (EZM) model of anxiety. The EZM paradigm has advantages over the elevated plus-maze (EPM) paradigm with respect to measuring anxiety, yet has been utilized less frequently. Three experiments were conducted each with a diazepam control (0.

Revisiting the serotonin-aggression relation in humans: a meta-analysis.

The inverse relation between serotonin and human aggression is often portrayed as "reliable," "strong," and "well established" despite decades of conflicting reports and widely recognized methodological limitations. In this systematic review and meta-analysis, we evaluate the evidence for and against the serotonin deficiency hypothesis of human aggression across 4 methods of assessing serotonin: (a) cerebrospinal fluid levels of 5-hydroxyindoleacetic acid (CSF 5-HIAA), (b) acute tryptophan depletion, (c) pharmacological challenge, and (d) endocrine challenge. Results across 175 independent samples and over 6,500 total participants were heterogeneous, but, in aggregate, revealed a small, inverse correlation between serotonin functioning and aggression, anger, and hostility (r = -.

Alcohol, violence, and the Alcohol Myopia Model: preliminary findings and implications for prevention.

This experiment provided a preliminary test of whether the Alcohol Myopia Model (AMM; Steele & Josephs, 1990) would provide a guiding framework for the prevention of alcohol-related violence. The model contends that alcohol has a "myopic" effect on attentional capacity that presumably facilitates violence by focusing attention onto more salient provocative, rather than less salient inhibitory, cues in hostile situations. Participants were 16 intoxicated male social drinkers who completed a laboratory task in which electric shocks were received from, and administered to, a fictitious opponent under the guise of a competitive reaction-time task while they were exposed to either violence-promoting (n=8) or violence-inhibiting (n=8) cues.

The disguise of sobriety: unveiled by alcohol in persons with an aggressive personality.

This investigation examined the factor structure of 8 well-validated self-report measures that assess traits that fall under the rubric of an "aggressive personality" and then determined how those factor(s) moderated the association between alcohol intoxication and aggression. Participants were 518 (252 men and 266 women) healthy social drinkers between 21 and 35 years of age. Following the consumption of an alcoholic or a placebo beverage, participants were tested on a laboratory aggression paradigm in which electric shocks were received from, and administered to, a fictitious opponent.

Alcohol dose and aggression: another reason why drinking more is a bad idea.

Objective: Numerous studies have examined the impact of alcohol on violence; however, only a small number have addressed differences elicited by different doses of alcohol. Such studies are limited by mixed findings, small sample sizes, inconsistent alcohol doses and control conditions, a bias toward studying only male participants, and the predominant use of only one particular measure to assess aggression. The present laboratory investigation was designed to elucidate and advance this literature by improving on these limitations.

Alcohol Myopia Revisited: Clarifying Aggression and Other Acts of Disinhibition Through a Distorted Lens.

The alcohol myopia model (AMM; Steele & Josephs, 1990) is reviewed in light of its unique ability to account for a variety of alcohol and nonalcohol-related disinhibited behaviors, particularly aggression. The AMM posits that alcohol has a narrowing, or a "myopic," effect on one's ability to attend to competing instigatory and inhibitory cues. Disinhibited behavior is presumed to occur when attention is directed toward salient provocative or instigatory cues rather than inhibitory cues.
