An Independent measure between groups design was applied to examine implicit attitudes towards sugary and diet food images, after consuming a sugary or diet beverage. Forty participants (13 males, 27 females) took part in the double-blinded condition using Open Sesame software. This true experiment employed Implicit Association Test measuring reaction times and correct/incorrect responses in the computer task. Self-Esteem was assessed using Rosenberg scale. Independent Sample T-tests on the D-scores examined three hypotheses. For the first hypothesis, no significant implicit food preference bias was seen. Also, no significant difference in the number of correct responses between the two conditions for hypothesis 2. There was no effect on sex on D-scores as predicted by hypothesis 3. Linear Regression did not show association between Self-Esteem and number of correct responses. However, certain patterns deserve further research.
