A fundamental question of attentional research concerns the perceptual consequences of attention. Spatial attention can enhance stimuli within the focus of attention relative to stimuli outside; or attention can remove the influence of distracting stimuli and other forms of external noise inside the focus of attention. It is known that both strategies apply(More)
Major clues to the human brain mechanisms of spatial attention and visual awareness have come from the syndrome of neglect, where patients ignore one half of space. A longstanding puzzle, though, is that neglect almost always comes from right-hemisphere damage, which suggests that the two sides of the brain play distinct roles. But tests of attention in(More)
BACKGROUND In response to conflicting reward (Behavioral Approach System [BAS]) and/or punishment cues (Fight-Flight-Freeze System [FFFS]) the Behavioral Inhibition System (BIS) inhibits behavior, leading to increased attention to threat, high anxiety, and behavioral ambivalence. The role of BIS in alcohol misuse is complex, as anxiety promotes(More)
BACKGROUND There is great interest in the role of the behavioral inhibition system (BIS) and the behavioral approach system (BAS) in the etiology of alcohol use because of the strong links of these systems to neuroscience and cognitive models of addiction. The revised Reinforcement Sensitivity Theory suggests that the strength of the BIS and BAS jointly(More)
Predrinking (or pregaming) is common among undergraduates and has been linked with problem alcohol use. While many students predrink to save money, evidence suggests that some students predrink to cope with social anxiety (SA). Tension reduction and cognitive theories predict that those high in SA may predrink to reduce anticipatory anxiety before attending(More)
Gray's Reinforcement Sensitivity Theory (RST) predicts that the Behavioral Inhibition System (BIS) may relate to coping-motivated problem gambling, given its central role in anxiety. Studies examining the BIS-problem gambling association, however, are mixed. The revised RST posits that the Behavioral Approach System (BAS) may moderate the effect of the BIS(More)
Reinforcement Sensitivity Theory predicts that those with a strong behavioral inhibition system (BIS) likely experience considerable anxiety and uncertainty during the transition out of university. Accordingly, they may continue to drink heavily to cope during this time (a period associated with normative reductions in heavy drinking), but only if they also(More)
Mindfulness encompasses four core skills: observing, describing, acting with awareness, and accepting without judgment; which aim to increase one's awareness, tolerance, and acceptance of internal experiences (Baer et al., 2004). Despite promising clinical results that mindfulness reduces alcohol craving and relapse, complementary etiological research is(More)
