Combined an individual should gain a positive emotional reaction when choices have beneficial consequences and will have negative emotional responses tied to choices that have greater negative consequences. In general, healthy responders to the IGT will begin to drift to the lower gain decks as they realize that they are gaining more money than they lose both through an ability to recognize that one is more consistently providing rewards as well as through the emotions related to winning consistently. However, those who have emotional deficits will fail to recognize that they are losing money over time and will continue to be more influenced by the exhilaration of higher value rewards without being influenced by the negative emotions of the loses associated with them.For more information concerning these process refer to the Somatic marker hypothesis

Differential Reinforcement of Low Response Rate Task
Differential reinforcement of low response rate (DRL) described by Ferster and Skinner is used to encourage low rates of responding. It is derived from research in operant conditioning that provides an excellent opportunity to measure the hyperactive childs ability to inhibit behavioral responding. Hyperactive children were relatively unable to perform efficiently on the task, and this deficit endured regardless of age, IQ, or experimental condition. Therefore, it can be used to discriminate accurately between teacher rated and parent rated hyperactive and nonhyperactive children.
Resisting the urge to act on impulses is important to teach children, because it teaches the value of delayed gratification. Many psychological problems are characterized by a loss of control or a lack of control in specific situations. Usually, this lack of control is part of a pattern of behavior that also involves other maladaptive thoughts and actions, such as substance abuse problems or sexual disorders like the paraphilias (e.g. pedophilia and exhibitionism). When loss of control is only a component of a disorder, it usually does not have to be a part of the behavior pattern, and other symptoms must also be present for the diagnosis to be made.

The five traits that can lead to impulsive actions
For many years it was understood that impulsivity is a trait but with further analysis it can be found that there were five traits that can lead to impulsive actions:
positive urgency, 
negative urgency,
sensation seeking, 
lack of planning, and
lack of perseverance. Associated behavioral and societal problems
Attention-deficit hyperactivity disorder
Attention deficit-hyperactivity disorder (ADHD) is a multiple component disorder involving inattention, impulsivity, and hyperactivity. The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) breaks ADHD into three subtypes according to the behavioral symptoms:
Attention-Deficit/Hyperactivity Disorder Predominantly Inattentive Type,
Attention-Deficit/Hyperactivity Disorder Predominantly Hyperactive-Impulsive Type, and
Attention-Deficit/Hyperactivity Disorder Combined Type. Predominantly hyperactive-impulsive type symptoms may include
fidgeting and squirming in seats,
talking nonstop,
dashing around and touching or playing with anything in sight,
having trouble sitting still during dinner/school/story time,
being constantly in motion, and
having difficulty doing quiet tasks or activities.
