Concept information
Preferred term
category size effect
Definition
- A memory phenomenon observed when the decision time in a sentence verification task is shorter for sentences about a member of a smaller semantic category (e.g., a canary is a bird) compared to a larger category (e.g., a canary is an animal).
Broader concept
Scope note
- Suppose that the following two sentences are to be verified: 1. The canary is a bird; 2. The canary is an animal. The decision time is shorter for the first sentence: the Bird category is less extensive than the Animal category. There are cases where the reaction time is shorter when the decision concerns the membership of a larger category: the reversal category size effect.
