As a matter of fact, the discrepancy hypothesis defines that an organism be present at and responds effectively to specific stimuli as a function of stimuli's bodily or perceptual discrepancy or dissimilarity from a well habituated standard stimulus. This means the moderate discrepancies from highly acknowledged stimuli take delivery of the highest degree of attention and positive influence. On the other hand, the stimuli that are extremely different or quite similar from the prior experience of the organism, receive relatively less attention and even less positive (sometimes negative) reactions and evaluations (Siegler et. al., 2005).
