People discount the value of delayed and uncertain outcomes, and how steeply individuals discount is thought to reflect how impulsive they are. From this perspective, steep discounting of delayed outcomes (which fails to maximize long-term welfare) and shallow discounting of probabilistic outcomes (which fails to adequately take risk into account)…

Ducharme, Joseph M.; Drain, Tammy L. – Journal of the American Academy of Child and Adolescent Psychiatry, 2004
Objective: Children with autism often demonstrate distress and oppositionality when exposed to requests to complete academic or household tasks. Errorless academic compliance training is a success-focused, noncoercive intervention for improving child cooperation with such activities. In the present study, the authors evaluated treatment and…

Reilly, Mark P.; Greenwald, Mark K.; Johanson, Chris-Ellyn – Psychological Record, 2006
The Stoplight Task, a procedure involving a computer analog of a stoplight, was evaluated for assessing risk taking in humans. Seventeen participants earned points later exchangeable for money by completing a response requirement before the red light appeared on a simulated traffic light. The green light signaled to start responding; it changed to…
