Deaf versus Hearing Subjects’ Recall of Words on a Distraction Task as a Function of the Signability of the Words 1

Abstract

Subjects, including 17 deaf and 10 hearing students in Grades 11 and 12, completed a test for memory of lists of 6 words (presented visually for 10 sec.). Subjects recalled the words in writing after a distracting task of adding pairs of digits for 10 sec. Word lists are categorized as signable with a single sign, compound or combination of signs, or finger-spelling signs only. Hearing subjects recalled significantly more words in each category than did deaf subjects. Deaf subjects recalled significantly more single-signed words than either of the other two categories. Deaf subjects did not recall more compound/combination signed words than words that could only be finger-spelled. Hearing subjects also recalled significantly more single-signed words than either of the other two categories and were not superior in either of the other categories.
