The Effects Of Working Memory On Decision Making Of Heroin...

The current paper examined the effects of working memory on decision making in cocaine addicts and healthy controls. As expected, we found that cocaine addicts exhibited decreased decision making performance compared to the healthy controls. Additionally, working memory was demonstrated to decrease decision making performance among participants. However, the combined effects of working memory and addiction on decision making resulted in an interaction. These findings support results from prior studies (Bechara Martin, 2004; Corbin, McElroy, Black, 2010; Grant, Contoreggi, London, 2000; Shiv Fedorikhin, 1999; Yan et al., 2014). Cocaine addicts exhibited decreased decision making performance on the Iowa Gambling Task compared to healthy controls. Previous findings have demonstrated similar results (Bechara Martin, 2004; Grant, Contoreggi, London, 2000; Yan et al., 2014). For example, Grant, Contoreggi, and London (2000) also found that addicted individuals performed worse on the Iowa Gambling Task compared to healthy controls. In the study done by Grant, Contoreggi, and London (2000), a majority of the drug addicts preferred to select cards from the decks that resulted in higher initial gains but also resulted in higher total losses. They explained that the relationship between addiction and decreased performance on the Iowa Gambling Task was due to increased impulsivity in drug addicts (Grant, Contoreggi, London, 2000).
