Familiarity Principle: This principle states that people prefer what they know. It's similar to the mere-exposure effect, as it also revolves around familiarity breeding liking or preference.
Classical Conditioning:This is a learning process through which an existing involuntary response is associated with a new stimulus. It can often lead to the mere-exposure effect if the stimulus becomes familiar over time.
Social Facilitation:This refers to the tendency for individuals to perform differently when in the presence of others than when alone. Familiarity (as in the mere-exposure effect) can influence this performance.
