Abstract

We examined the contribution of first-person sensory experience to concepts by comparing the meanings of perception (visual/tactile) and emission (light/sound) verbs among congenitally blind (N = 25) and sighted speakers (N = 22). Participants judged semantic similarity for pairs of verbs referring to events of visual (e.g. to peek), tactile (e.g. to feel) and amodal perception (e.g. to perceive) as well as light (e.g. to shimmer) and sound (e.g. to boom) emission and manner of motion (to roll) (total word pairs, N = 2041). Relative to the sighted, blind speakers had higher agreement among themselves on touch perception and sound emission verbs. However, for visual verbs, the judgments of blind and sighted participants were indistinguishable, both in the semantic criteria used and subject-wise variability. Blind and sighted individuals alike differentiate visual perception verbs from verbs of touch and amodal perception and differentiate among acts of visual perception e.g. intense/continuous from brief acts of looking (e.g. peek vs. stare). Light emission verbs are differentiated according to intensity (blaze vs. glow) and stability (blaze vs. flash). Thus detailed knowledge of visual word meanings is acquired without first-person sensory access.
