“…The participants were then asked to drink beer (alcoholic or non-alcoholic) over 15 min, and tests were performed starting 30 min after the start of beer intake when maximal effects were expected (Bershad et al 2015). We used a low-to-moderate dose of alcohol that sought to achieve a BAC of 0.4 g/L, which was associated with alterations in emotion recognition in some previous studies but not expected to result in nonspecific performance deficits (Attwood et al 2009a). The amount of alcohol was estimated for each participant based on sex and body weight according to the formula presented by Fisher et al (Fisher et al 1987): Target BAC = 0.4 g/L = G × 100 × 0.8 / (W × F), where G is the grams of alcohol, W is the body weight (in kilograms), and F is the conversion factor for the calculation of total body water (0.583 and 0.485 in male and female participants, respectively).…”

“…Visual analog scales (VASs; (Attwood et al 2009a;Bershad et al 2015;Hysek et al 2012) were used to assess the subjective effects of alcohol, including feeling "any effect," "stimulated," "happy," "talkative," "open," "be with others," and "be alone," before and 30, 70, and 95 min after beer administration. The VASs were presented as 100 mm horizontal lines that were marked ''not at all'' on the left and ''extremely'' on the right.…”

Alcohol acutely enhances decoding of positive emotions and emotional concern for positive stimuli and facilitates the viewing of sexual images

Rationale: Social cognition influences social interactions. Alcohol reportedly facilitates social interactions. However, the acute effects of alcohol on social cognition are relatively poorly studied. Methods: We investigated the effects of alcoholic or non-alcoholic beer on emotion recognition, empathy, and sexual arousal using the dynamic face emotion recognition task (FERT), Multifaceted Empathy Test (MET), and Sexual Arousal Task (SAT) in a double-blind, random-order, cross-over study in 60 healthy social drinkers. We also assessed subjective effects using visual analog scales (VASs), BACs, and plasma oxytocin levels. Results: Alcohol increased VAS ratings of stimulated, happy, talkative, open, and want to be with others. The subjective effects of alcohol were greater in participants with higher trait inhibitedness. Alcohol facilitated the recognition of happy faces on the FERT and enhanced emotional empathy for positive stimuli on the MET, particularly in participants with low trait empathy. Pictures of explicit sexual content were rated as less pleasant than neutral pictures after non-alcoholic beer but not after alcoholic beer. Explicit sexual pictures were rated as more pleasant after alcoholic beer compared with non-alcoholic beer, particularly in women. Alcohol did not alter the levels of circulating oxytocin. Conclusions: Alcohol biased emotion recognition toward better decoding of positive emotions and increased emotional concern for positive stimuli. No support was found for a modulatory role of oxytocin. Alcohol also facilitated the viewing of sexual images, consistent with disinhibition, but it did not actually enhance sexual arousal. These effects of alcohol on social cognition likely enhance sociability.

“…An early meta-analysis (Hull and Bond 1986) of the anticipated and pharmacological effects of alcohol concluded that the anticipated effects of alcohol have important behavioural consequences, arguing the belief that one is intoxicated may provide an excuse not to inhibit behaviour. However, using balanced placebo designs, (randomly allocating participants to be told they will receive an alcoholic or non-alcoholic drink, despite actual content) both Craig et al (2009) and Attwood et al (2009) found pharmacological, but not anticipated, effects of alcohol on emotional perception. With regard to the alcohol priming effect, we (Christiansen et al 2013) utilised a partially balanced placebo design in which participants received alcoholic, placebo and control drinks.…”

RationaleAcute ‘priming’ doses of alcohol reliably increase alcohol-seeking behaviour in social drinkers. However, the effects of the anticipated (rather than pharmacological) effects of alcohol, and their interaction with contextual alcohol cues, are not well understood.ObjectivesThis study aims to determine the extent to which an alcohol-placebo drink increases craving, subjective intoxication and beer consumption, while conjointly investigating the impact of contextual alcohol cues.MethodsOn a within-subject basis, 64 undergraduate social drinkers consumed both a placebo (which they believed to contain alcohol) and a control drink (which they knew did not contain alcohol) in different sessions. Participants completed the study procedures in a bar laboratory designed to look like a ‘pub’ or a standard psychology lab containing no alcohol-related cues. Craving (Desires for Alcohol Questionnaire) and subjective intoxication were measured pre- and post-drink, and a bogus taste test to measure ad-lib alcohol consumption was completed at the end of each session.ResultsCompared to the control drink, placebo significantly increased craving, ad-lib consumption and subjective intoxication, regardless of environmental context.ConclusionsIncreased craving and ad-lib alcohol consumption after consuming a priming dose of alcohol is at least partly attributable to the anticipated rather than the pharmacological effects of the priming dose.Electronic supplementary materialThe online version of this article (doi:10.1007/s00213-016-4518-0) contains supplementary material, which is available to authorized users.

“…Preliminary evidence suggests that acute alcohol use may impair basic affective processing skills, with subtle gender differences in alcohol’s acute effects. For example, acute alcohol administration, but not placebo, leads to misidentification of emotional faces, (Attwood et al, 2009a) and males had more difficulty correctly labeling a sad facial emotion compared with females following a high dose of alcohol (Attwood et al, 2009b). Gilman and colleagues (2008) reported that acute alcohol consumption increased activation to fearful stimuli in striatal regions, but attenuated activation in visual and limbic areas.…”

Background Alcohol dependence (AD) has global effects on brain structure and function, including frontolimbic regions regulating affective processing. Preliminary evidence suggests alcohol blunts limbic response to negative affective stimuli and increases activation to positive affective stimuli. Subtle gender differences are also evident during affective processing. Methods Fourteen abstinent AD individuals (8 F, 6 M) and 14 healthy controls (9 F, 5 M), ages 23 to 60, were included in this facial affective processing functional magnetic resonance imaging pilot study. Whole-brain linear regression analyses were performed, and follow-up analyses examined whether AD status significantly predicted depressive symptoms and/or coping. Results Fearful Condition—The AD group demonstrated reduced activation in the right medial frontal gyrus, compared with controls. Gender moderated the effects of AD in bilateral inferior frontal gyri. Happy Condition—AD individuals had increased activation in the right thalamus. Gender moderated the effects of AD in the left caudate, right middle frontal gyrus, left paracentral lobule, and right lingual gyrus. Interactive AD and gender effects for fearful and happy faces were such that AD men activated more than control men, but AD women activated less than control women. Enhanced coping was associated with greater activation in right medial frontal gyrus during fearful condition in AD individuals. Conclusions Abnormal affective processing in AD may be a marker of alcoholism risk or a consequence of chronic alcoholism. Subtle gender differences were observed, and gender moderated the effects of AD on neural substrates of affective processing. AD individuals with enhanced coping had brain activation patterns more similar to controls. Results help elucidate the effects of alcohol, gender, and their interaction on affective processing.
