Impulsive behaviour?
Researchers at the University of Cambridge in the United Kingdom who are studying laboratory rats have linked impulsive behavior to cocaine addiction. In the addiction field, it has been unclear to many scientists which came first, the impulsive behavior or the cocaine addiction leading to impulsivity.
Now, the researchers believe the behavior comes first. The researchers separated out two groups. The first was the impulsive group and the second was the thrill seeking group. The thrill seeking group sampled the cocaine first, but quickly lost interest thereafter. The impulsive group was slower to sample cocaine, but also was the group that became addicted.
