Research summary
Perception of food is a key factor in the decision making process of what we eat. As such, this project will be investigating the link between visual food cues and the resulting decision process. We hypothesise that there is an altered visual food-cue associated reward in overweight/obese. We are aiming to use eye-tracking methodology to identify behavioural responses to visual food cues and compare results between patients before and after treatment for obesity.
We aim to test this hypothesis with various tasks making up the study. The tasks are briefly outlined below:
Task 1: Obese patients will be asked to eat a plate of food whilst their gaze behaviour is tracked
Task 2:Obese and Non-Obese participants will be asked to choose food from a menu whilst their gaze behaviour is tracked
Task 3: Obese and Non-Obese participants will be asked to choose items to purchase at a supermarket whilst their gaze behaviour is trackedREC name
