Go/no-go task: A total of 200 trials were presented, 100 (in two blocks of 50) for the neutral task (a) and the same for the food task (b). Images were presented using a ratio of 80% ‘go’ to 20% ‘no-go’ trials to create a prepotent ‘go’ response. Each trial was presented for 750 ms and was separated by a blank screen for 500 ms and preceded by a fixation point for 500 ms. The go and no-go categories were presented in a pseudorandomised order, with 3, 4 or 5 go trials in between every no-go trial. Presentation order of the food and neutral tasks was fully counterbalanced.
