The effect of proactive motor control on impulsive gambling and eating behaviour

Background
Response inhibition or ‘impulse control’ is a hallmark of flexible and intelligent behaviour, required whenever a thought or action must be stopped or restrained. Existing evidence suggests that linked or common mechanisms may coordinate response inhibition in multiple domains, although evidence for causal links has emerged only recently.
Methods and Results
I will discuss some of our recent studies that explored the causal relationship between motor response inhibition and different forms of impulsive decision-making. In a series of studies we have found that performing a stop-signal task – which induces cautious motor responding – reduced gambling in a multitask situation. We also found that a short period of inhibitory training reduced gambling at least two hours later in time. Our most recent experiments have shown that the effects of inhibition training can transfer to eating behaviour, reducing the tendency to make unhealthy choices.
Discussion
Overall, our findings converge with work in other labs to indicate that proactive motor control interacts strongly with decision-making. This link between different levels of cognitive control might be exploited as an adjunct to existing rehabilitation methods in addiction.
