People who have a problematic relationship with gambling have gambling disorder (GD). Research suggests that people with GD have difficulties in regulating their actions. This study aimed to assess how people with GD performed on behavioural tasks. These behavioural tasks measured their response inhibition and their resistance to distractor interference. The researchers also used a brain scanning technique to see if performance on these tasks was related to neurochemical levels in specific regions of the brain. This study found that people with GD were slower during the distractor interference task. Neurochemical levels in the dorsal anterior cingulate cortex area of the brain seemed to be involved in their resistance to distractor interference.
