Popis:	Sign-tracking, as a classically conditioned behavior, is of interest due to its relation to impulsivity and addiction. Caffeine affects the activity of neurotransmitters linked to sign-tracking such as dopamine and acetylcholine. As such, acute caffeine administration may enhance sign-tracking behavior. Caffeine was found to enhance measures of sign-tracking behavior in Sprague-Dawley rats in a sign/goal-tracking procedure. It is suggested that part of caffeine's effects on cognition may be due to its ability to enhance incentive salience in conditioned stimuli.
