Comprehension of inflectional morphemes by deaf children exposed to a visual English sign system.
A test of morpheme-based concepts was administered to 67 deaf children who were exposed to Seeing Essential English (SEE). Results indicated that these children show the following order of acquisition for the inflectional morphemes tested: plural -s, past tense -ed, present progressive -ing, possessive -'s, third person present indicative -s, comparative -er, superlative -est, and present perfect -en. There were no effects of sex, age, or school from which the subjects were selected. The main contribution to the subjects' performances were their lengths of exposure to SEE.
