Mere-Exposure Effect

What does it mean in everyday language?

Something initially unfamiliar may become more appealing as you encounter it again. You do not always need new information about it for your preference to change.

An example

Hypothetical example: a person sees the same fictional digital character across several videos and gradually finds its appearance more appealing.

A more precise definition

The mere-exposure effect is an increase in positive evaluation associated with repeated exposure to a stimulus, such as an image, sound, or symbol. Its occurrence and size depend on the stimulus and the conditions of exposure.

Key features

• Concerns liking or preference
• Does not require an explicit persuasive argument
• Depends on the stimulus and pattern of exposure

Where the definition stops

It is different from the illusory truth effect, which concerns belief in a statement. Repetition does not guarantee affection, trust, or a stronger preference without limit.

How it relates to synthetic imprinting

It may help explain growing familiarity with a generated character. That possibility should be tested separately from memory changes or belief in the character's claims.

Research context

Zajonc's foundational research examined how exposure alone can affect evaluation. Applying that finding to repeated AI interactions requires evidence about the specific content, audience, and outcome.
