Word norms for blind and sighted subjects: Familiarity, concreteness, meaningfulness, imageability, imagery modality, and word associations

Abstract

Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects' ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness. © 1991 Psychonomic Society, Inc.
