The architecture of prototype preferences: Typicality, fluency, and valence

Area of Science:

• Cognitive Psychology
• Social Psychology

Background:

• The prototype preference effect (PPE) suggests individuals prefer prototypical exemplars over atypical ones within a neutral category.
• Existing explanations for PPE include deviance avoidance, hedonic fluency, and familiarity.
• Typicality may also enhance category-related information activation, linking prototypes to category valence.

Purpose of the Study:

• To investigate whether the evaluation of prototypes is influenced by the valence (positive or negative) of their associated category.
• To challenge existing explanations of prototype evaluation by examining the role of category valence.

Main Methods:

• Three experiments were conducted, combining the standard PPE paradigm with evaluative conditioning procedures.
• Participants evaluated exemplars from categories with varying typicality and valence.

Main Results:

• For positive categories, increased typicality led to greater liking, consistent with PPE.
• Crucially, for negative categories, increased typicality resulted in decreased liking.
• This valence-dependent effect on liking was observed across experiments.

Conclusions:

• Prototype evaluation is not solely based on typicality but is significantly moderated by category valence.
• Greater typicality enhances liking for positive categories but diminishes liking for negative categories.
• These findings challenge established theories of PPE and highlight the role of associative learning in object evaluation.
