Memory for faces, shoes, and objects by deaf and hearing signers and hearing nonsigners

Abstract

The visual spatial memory of 15 deaf signers, 15 hearing signers, and 15 hearing nonsigners for shoes, faces, and verbalizable objects was measured using the game Concentration. It was hypothesized that the deaf and hearing signers would require fewer attempts than the hearing nonsigners on the shoes and faces tasks because of their experience of using a visual-spatial language; and, in the case of the Deaf, also possibly, due to a compensatory mechanism. It was also hypothesized that memory for shoes would be more like that for faces than for simple objects. It was also anticipated that there would be no difference between the three group's memories for verbalizable objects. Deaf signers were found to be similar to hearing signers, both of whom were better than hearing nonsigners on the faces and shoes tasks. Generally, performance on the faces and shoes tasks was similar and followed the same pattern for the three groups. The three groups performed at a similar level on the objects task. There were no gender differences.
