An investigation into the sub-acute effects of ecstasy on aggressive interpretative bias and aggressive mood - are there gender differences?
Abstract
The lowering of serotonin for a period following MDMA use could account for the increases in both self-rated and objective measures of aggression previously found in ecstasy users several days after taking the drug. There is some evidence of gender differences in the acute, sub-acute and long-term effects of MDMA use, and given that gender differences have been found in aggression, it is possible that men may experience more aggression mid-week than women. The aim of this study was to attempt to replicate findings showing increased bias towards aggressive material in ecstasy users several days after using the drug. In addition, to investigate possible gender differences in mid-week aggression. A total of 46 participants were tested: 19 ecstasy users and 27 controls were compared on the night of drug use and 4 days later. On day 4, a task designed to tap cognitive bias toward material with aggressive content was administered. Participants were required to process sentences that could be interpreted as either aggressive or neutral and subsequently remember them in a recognition test. This data set was then combined with the data from Curran et al.'s (2004) study that employed exactly the same procedure. Thus, the data from 107 pa...Continue Reading
