“…It is well deficit disorder [47]. Alpha activity, especially in alpha2, has also E known that the parietal lobes play a fundamental roll in orientation and selective attention [45], that beta activity has been associated with vigilance and selective attention [18,46], and that a decrease in this band has been observed in psychopathological states, such as attention cognitive process that has been shown to be sensitive to the effects of alcohol, so our EEG data are congruent with the findings of several other studies that have demonstrated that alcohol has a deleterious effect on attention [3,50], and reduces cortical arousal [51].…”

Although the combination of alcohol and sex is frequently observed in human social interaction, many questions concerning alcohol's effects on the processing of sexual stimuli and brain functionality remain unanswered. Erotic films eliciting sexual arousal in humans and affect electroencephalographic (EEG) activity. This study examines the effects of alcohol on cortical EEG activity in young men while viewing an erotic film. Heterosexual males participated in an independent alcohol/placebo group protocol. Thirty-five minutes after beverage ingestion, EEGs were recorded at prefrontal, temporal and parietal derivations in three conditions: baseline, and while watching erotic and neutral films. During the observation of erotic films, only the participants who drank the placebo beverage showed a decrease in alpha1 and an increase in the fast frequencies of the prefrontal regions, as well as a decrease in inter-prefrontal synchronization in the alpha and beta bands. Alcohol suppressed the prefrontal EEG changes associated with watching erotic visual stimuli without affect the sexual arousal. EEG data show that alcohol affecting the functioning of the prefrontal cortex, which could interfere with the adequate processing of visual erotic stimuli. These findings may contribute to improving our understanding of the brain mechanisms that underlie alcohol's effects on the processing of sexual stimuli.

“…Fillmore and Selst (2002) showed that alcohol reduces the capacity to process information necessary for the execution and suppression of responses in dual-task, but not singletask, conditions. Finally, Curtin, Patrick, Lang, Cacioppo, and Birbaumer (2001) showed that, during intoxication, reductions in fear response (assessed via startle potentiation) occurred only under dual-stimulus conditions and coincided with reduced attentional processing of threat cues as evidenced by brain responses (indexed via P3 ERPs). Thus, overall, our results fit very well with such findings and the general view that alcohol consumption affects the processing of unattended information by reducing the resources available to process them.…”

Because of the biological significance of emotional stimuli, their processing is considered largely automatic. In the study reported herein, we tested the alternative hypothesis-namely, that the processing of emotional stimuli requires some level of attention. Our experiments utilized highly negative and arousing visual stimuli comprising mutilated bodies. All experiments employed a single task, which consisted of determining whether two peripheral bars were like oriented or not, thereby eliminating potential task-difference confounds that may have contaminated prior studies. Our results revealed that task-irrelevant unpleasant images slowed reaction time during the performance of the main task. Such interference was modulated by task difficulty as well as by alcohol consumption, showing that the processing of emotional visual stimuli is not immune to attentional manipulations. These results suggest that it is essential to utilize attentional manipulations that more fully consume attentional resources in order to demonstrate that the processing of emotional stimuli is resource limited.

Fear of certain threat and anxiety about uncertain threat are distinct emotions with unique behavioral, cognitive-attentional, and neuroanatomical components. Both anxiety and fear can be studied in the laboratory by measuring the potentiation of the startle reflex. The startle reflex is a defensive reflex that is potentiated when an organism is threatened and the need for defense is high. The startle reflex is assessed via electromyography (EMG) in the orbicularis oculi muscle elicited by brief, intense, bursts of acoustic white noise (i.e., "startle probes"). Startle potentiation is calculated as the increase in startle response magnitude during presentation of sets of visual threat cues that signal delivery of mild electric shock relative to sets of matched cues that signal the absence of shock (no-threat cues). In the Threat Probability Task, fear is measured via startle potentiation to high probability (100% cue-contingent shock; certain) threat cues whereas anxiety is measured via startle potentiation to low probability (20% cue-contingent shock; uncertain) threat cues. Measurement of startle potentiation during the Threat Probability Task provides an objective and easily implemented alternative to assessment of negative affect via self-report or other methods (e.g., neuroimaging) that may be inappropriate or impractical for some researchers. Startle potentiation has been studied rigorously in both animals (e.g., rodents, non-human primates) and humans which facilitates animal-to-human translational research. Startle potentiation during certain and uncertain threat provides an objective measure of negative affective and distinct emotional states (fear, anxiety) to use in research on psychopathology, substance use/abuse and broadly in affective science. As such, it has been used extensively by clinical scientists interested in psychopathology etiology and by affective scientists interested in individual differences in emotion.
