The aim of this study was to compare the effectiveness of classical conditioning (CC) and the effect of mere exposure (ME) in supraliminal conditions (2000 milliseconds -ms-) on the formation of preferences for brands advertising. An experiment was conducted with an intra-subject design, where the affective variable was manipulated by the two processes to compare and the dependent variable -preference toward brands- was measured through a forced-choice task and a semantic differential. The participants of the experiment were 70 men, medical students from the Universidad del Rosario aged between 18 and 22 years. The CC was performed using a simultaneous procedure and the independent variable conditions was exposed 8 times with a duration of 2000 ms. The results showed that the two procedures generated preferences in participants, but there’s not significant differences between the effectiveness of the procedures.
