Models of Addiction

Locate an article in the library written within the last five years that describes a specific treatment for an addictive disorder. Identify which model of addiction would be most consistent with that treatment approach. If no single model appears to help explain the assumptions about addiction underlying that treatment, select the aspects of the two models that come closest. How does that model support current treatment approaches?

Bechara, Noel, & Crone (2006) provide an explanation regarding the mechanism that allows one to sacrifice something for rewards later, which can be linked to a neural imbalance. They utilize the example of addiction to explain a neural imbalance that takes place between two separate, and interacting neural systems that are dysfunctional. According to Bechara et al, the imbalance in addiction is caused by an impulsive amygdala (structure of the brain mostly responsible for memory). The amygdala is a dependent system for signaling pain or pleasure, and (2) a reflective orbitofrontal system--a structure of the neural system of the brain involving processes such as emotions and decision-making. A condition that leads to this imbalance includes a dysfunctional reflection system and a hyperactive impulsive system.

For instance, drugs can acquire triggering involuntary signals through the amygdala that modulates goal-driven attentional resources needed for the normal operation of a reflecting system and exercising the will. For instance, according to Van Rensburrg, Taylor, & Holgson. (2009), research is presented to show that suggest differences in smokers and non-smokers across a wide ...
