The purpose of this study was to investigate the role of rehearsal in the short-term memory of visually-presented linguistic material in deaf students. An experimental approach was employed to determine if instruction in overt dactylic and articulatory rehearsal would make a difference in the short-term recall of verbal material. In addition, the study investigated the role of age in the development of short-term memory in deaf children.The subjects in the study were 87 prelingually deaf students at a state residential school for the deaf. The subjects were between the ages of 6-2 and 13-8 and were of at least low average non-verbal intelligence. Subjects were randomly assigned to one of three treatment conditions: (a) instruction in overt dactylic rehearsal, (b) instruction in overt articulatory rehearsal, or (c) no instruction in rehearsal.All subjects received treatment in groups of four to six for one session which lasted approximately 30 minutes. The task consisted of a 5-second exposure to two groups ofCVC trigrams followed by a 15-second rehearsal time. The subjects were then asked to record in writing their recall of the stimulus. Each group received five practice trials I followed by ten test trials. The dependent variable was the number of letters recalled correctly in the correct position.The results of the study were analyzed through multiple regression analysis with age as a covariate. While short-term recall was shown to correlate with age at the .001 level, there were no significant differences among the treatment groups. Consequently, the results of this investigation did not support the hypothesis that instruction in overt dactylic or articulatory rehearsal would significantly improve short-term recall of visually-presented verbal material in deaf students. Nor did the study indicate that the method of overt rehearsal employed would produce significantly different results.
