Twenty men and 20 women from the University o f Western Ontario and its affiliate colleges were recruited to complete a study regarding the effects that images of food have on hunger. It was hypothesized that women would have more increased feelings of hunger after being exposed to images of low-caloric foods than high-caloric foods, and men would have increased feelings of hunger after seeing images of high-caloric foods than low-caloric foods.
Individuals completed a five-point scale o f immediate hunger, and then were shown images of either high-caloric or low-caloric foods, which they wrote a descriptive paragraph about in order to ensure that the images were viewed adequately. Participants then reassessed their hunger on a five-point scale. The results found no main effect for gender (male/female) or food image condition (high-calorie/low-calorie), but an interaction effect was found between the independent variables, F (1,36) = 1.12, p < 0.05, partial p n² = 0.18. Issues and improvements of the design were discussed, as well as suggestions for future studies.
