attention and may be rapid, learned, but not impulsive. Impulsivity assessments have included urgency, lack of premeditation, lack of perserverance and sensation seeking (Congdon and Canli, 2008). Urgency motivating impulsive behaviors overlaps with concepts of addition that suggest chronic substance abuse increases reward value while decreasing inhibitory control (Jentsch and Taylor, 1999; Robinson and Berridge, 2003). Executive functions are often invoked to override responses that have been automatically elicited. The frontal lobe executive functions receive input from all sensory modalities, integrate memories and using working memory of temporary information, assemble reward and valuation information with timing of events to carry out planned behaviors. An individual's activity can be altered by environmental factors that change directed goals. For example, smelling popcorn will distract individuals, draw them to the source, induce hunger and automatically stimulate eating. This is normal; however, not all will be distracted. People, who are dieting, activate executive functions drawing attention to the distracting smell and block eating, often through a strategy of leaving the area and avoiding further distraction. Similar factors may be involved in alcoholic cues promoting drinking and causing relapse. Attention and impulse inhibition can block the movement to and eating of the popcorn or responding
