Better Working Memory, Less Temptation: Substance Abuse and Neuro-Mechanisms
New research published in the journal Addiction suggests that poor working memory and the inability to control impulses during adolescence are key predictors for future substance abuse. ‘Working memory’ refers to one’s capacity to concentrate on a given task without being easily distracted. Young people with a poor working memory often have difficulties controlling impulsive behaviour.
The lead author of the investigation notes: “There is a lot of research that links early onset of [substance] use to later substance use disorders. Our study advances the field by showing that just addressing early use is not going to solve the problem.” Indeed, the paper recommends that interventions ought to target neurobehavioural mechanisms as well. By looking for ways of improving working memory, as well as related cognitive processes that inhibit impulsive behaviours, prevention programmes can better equip teenagers to resist indulging in substance abuse.
