Inhibitory Control Smartphone App

"The control version is a smartphone-compatible CGNG. The cued go/no-go (CGNG) tests ability to respond fast to go targets (activation) while withholding response to no-go targets (inhibition)."

The standard version is the same as the control version with the exception that information about performance (correct or incorrect) is displayed along with RT in ms for a correct response during each inter-trial interval.

The experimental, feedback version includes the standard plus feedback on RT and inhibition errors compared to pre-drinking. The app will state that there are simple alternatives with invitation to press a box to view advice, based on research that risk information may increase risky behavior if convenient options are not given73. Feedback will be worded non-judgmentally per motivational interviewing tenets.
