High Impulsivity And Novelty Seeking Drugs

The article, High Impulsivity Predicts the Switch to Compulsive Cocaine-Talking, sought to determine whether impulsivity and novelty-seeking (which are behavioral markers of addictive drugs) place individuals in the vulnerability of compulsive seeking of the drug. The researchers used laboratory rats to test the vulnerability. Researchers found that high reactivity to novelty predicted the likelihood of rats seeking cocaine self-administration. However, high impulsivity seemed to predict the development of addiction like behavior in the laboratory rats. The results obtained by researchers has changed the perspective from the impulsivity aspect of drug use towards the compulsivity factor during the initial stages of addiction development. Interestingly, the compulsive factor can be generated through neural physiology (i.e. neural mechanisms or diminished function of cortical function). In terms of lecture material, as discussed, drugs (such as stimulants) produce a hedonic state in individuals that leads them to greater drug use. The sensation of false euphoria can be what drives individuals who actively seek the drug. This can make drug users to impulsively seek drugs. As stated in the article, their evidence demonstrated that high levels of impulsivity can come before the onset of compulsive drug use. As discussed in lecture, although cocaine and caffeine are considered to be both stimulants, their effects are very different. There is a particular mechanism of biological
