Generic Training
In the go/no go training, participants are shown images in which high-calorie foods are shown on one side of the screen and low-calorie foods on the other. They are told to press response keys as quickly as possible to indicate the side of presentation (go-trials). On half of the trials, the rectangular frame surrounding the image is not solid but hatched, which is a signal for them to withhold their response (no-go trials). This training is divided into 4 blocks of 50 trials.
In the stop signal training, participants are shown images in either a dark blue or light gray border. They are told to press the space bar as quickly as possible when the border is blue (go trials) and to withhold a response when the border is gray (no-go trials). This training is divided into 20 blocks of 32 trials.
In the dot-probe training, participants are shown images in which high-calorie foods are shown on one side of the screen and low-calorie foods on the other. Immediately after the images disappear, a small dot probe appears in the location of one of the images. Participants are told to press response keys as quickly as possible to indicate whether a visual probe appeared behind the left or right image during the trials. The probe appears in the location occupied by a high-calorie food image 10% of the time and in the location occupied by a low-calorie food image 90% of the time. This training is divided into 6 blocks of 40 trials.
In the generic training, participants complete a generic go/no-go training that uses images of flowers and office supplies instead of the images of high-calorie and low-calorie food images. This generic go/no go training is identical in duration and contact time to the go/no-go food training.
