Academic Abstract: In the present review, we propose a theory that seeks to recontextualize various existing theories as functions of people's perceptions of their consistency with those around them. This theory posits that people seek social consistency for both epistemic and relational needs and that social inconsistency is both negative and aversive, similar to the experience of cognitive dissonance. We further posit that the aversive nature of perceiving social inconsistency leads people to engage in various behaviors to mitigate or avoid these inconsistencies.

Attachment insecurity has been associated with negative behaviors during conflict and decreased relationship satisfaction. We theorize that individuals high in attachment anxiety and/or avoidance are less mindful during conflict with their romantic partners, and thus more likely to ruminate. Decreased mindfulness and higher levels of rumination may be important mechanisms in the relationship between attachment insecurity and conflict behavior, as it may be more difficult to engage in constructive problem-solving skills when one is distracted from the present moment.

Previous work has reliably demonstrated that when people experience more subjective ambivalence about an attitude object, their attitudes have less impact on strength-related outcomes such as attitude-related thinking, judging, or behaving. However, previous research has not considered whether the amount of perceived knowledge a person has about the topic might moderate these effects. Across eight studies on different topics using a variety of outcome measures, the current research demonstrates that perceived knowledge can moderate the relation between ambivalence and the impact of attitudes on related thinking, judging, and behaving.

Background: Influenza vaccination of healthcare workers (HCW) is important for protecting staff and patients, yet vaccine coverage among HCW remains below recommended targets. Psychological theories of behavior change may help guide interventions to improve vaccine uptake. Our objectives were to: (1) review the effectiveness of interventions based on psychological theories of behavior change to improve HCW influenza vaccination rates, and (2) determine which psychological theories have been used to predict HCW influenza vaccination uptake.

Attachment anxiety is negatively associated with condom use; however, little research has assessed mechanisms underlying this relationship. In two studies we assessed the relationships among attachment orientations, perceived partner rejection, and condom use. In Study 1 we used a survey methodology and found that a measure of perceived partner rejection mediated the relationship between attachment anxiety and reported condom use behavior.

We hypothesized that the effect of initiator status on post breakup distress would vary as a function of trait self-esteem, such that individuals with low self-esteem would experience more distress after being rejected by their partners, whereas, among individuals with high self-esteem, initiator status would not predict distress. We used a prospective design in which university students (N=66) were assessed for emotional responses following the dissolution of their real-life romantic relationships, as well as a laboratory design in which students (N=190) imagined breaking up with their partners. As predicted, participants with lower trait self-esteem exhibited greater distress after experiencing or imagining a romantic rejection than after ending or imagining themselves ending their relationships.

Two prospective studies examined the self-regulatory role of anticipated negative self-conscious emotions (ANSCE) in the theory of planned behavior. In Study 1, 147 undergraduates reported condom attitudes, perceived norms, self-efficacy, ANSCE (shame and guilt) should they not use condoms, and intentions to use condoms during the coming 6 weeks. At a 6-week follow-up, ANSCE predicted condom use intentions and behavior and partially mediated the effect of attitudes and norms on both.

The authors developed and evaluated the psychometric properties of the 18-item Personal Acquaintance Measure (PAM) and investigated how the PAM relates to self- other agreement in personality ratings. Results support that 6 factors represent the PAM (Duration, Frequency of Interaction, Knowledge of Goals, Physical Intimacy, Self-Disclosure, Social Network Familiarity), which showed evidence of internal consistency, test-retest reliability over 3 weeks, sensitivity to known group differences, discriminant validity from socially desirable responding, and convergent validity with other relationship inventories. Results also show that the PAM positively predicted self-other agreement.

Condom use interventions may be more powerful if they provide cues to recall safe-sex messages when sexual activity occurs. The authors tested this notion by assigning sexually active introductory psychology students (N = 196) to a standard safe-sex intervention, a safe-sex with reminder intervention, or a control (drinking and driving) intervention. Participants assigned to the reminder intervention were given a "friendship bracelet" to wear and were instructed to have the bracelet remind them of the intervention.

The current study investigated whether acute alcohol intoxication produces impaired decision-making on tasks assessing ventromedial prefrontal (VMF) cortex functioning and impulsive responding. Participants completed the Iowa Gambling Task (IGT), a decision-making test targeting the VMF, and the Newman Perseveration Task (NT), a measure of impulsivity. Personality measures of impulsivity were assessed using the Barratt Impulsiveness Scale (BIS).

Aims: Animal experimentation often demonstrates that alcohol leads to disinhibited behaviour, such as increased aggression, increased social behaviour, or increased impulsivity. However, human experimentation demonstrates that alcohol can have either disinhibiting or inhibiting effects on behaviour, depending on salient environmental cues. Our aim was to illustrate how alcohol myopia theory could be applied to the literature assessing the effects of alcohol on behaviour in animals.

Aims: To examine the moderating effects of alcohol myopia on cognitive impulsivity in humans using the delay-discounting paradigm.

Methods: Seventy-six male undergraduate students were randomly assigned to sober, placebo or alcohol conditions. In the delay-discounting task, participants made a series of hypothetical choices between a small, immediate reward and a large, delayed reward.

The effect of alcohol on identification accuracy is potentially an important topic. This study examined the effects of alcohol consumption on identification accuracy from showups, the identification procedure most likely to be used by police with intoxicated witnesses. The blood alcohol level of people exposed to a target was measured.
