Validating an Experimental Model of Snaking Behaviours

Abstract

This experiment was carried out to assess the snacking behaviours among Bangor University students. 25 participants were considered in the research. However, 6 of them were excluded because they did not comply with the experimental procedures and, therefore, had to be eliminated from the study. The main objective was to assess the preference for variable delays over fixed delays to food rewards in humans. T-tests and correlations were performed to assess the hypothesis in the 7-trial block design experiment. Several psychological tests were administered as a strategy of ensuring that the results were free from bias of unintended variables and sample characteristics such as eating disorders. The results indicated that participants favoured fixed delays which had higher food reward compared to variable delays. This was prevalent among high BMI individuals.
