Multisensory Stop Signals Can Reduce the Disinhibiting Effects of Alcohol in Adults.

Alcohol impairs drinkers' abilities to inhibit inappropriate responses. Certain stimulus conditions have been shown to facilitate behavioral control. Under conditions where individuals are presented with multiple inhibitory signals, the speed and consistency with which they are able to inhibit a response is improved. Recent research has shown that multisensory signals might protect against the disruptive effects of alcohol on mechanisms of behavioral control. This study examined whether multisensory stop signals can be used to improve inhibitory control, possibly by speeding attentional shifts toward inhibitory "stop" signals in the environment.
