Orally trained, profoundly deaf children's short‐term memory for lip‐read, signed and graphic stimuli was investigated using the serial ordered recall paradigm. Experiment 1 showed that both deaf and normally hearing boys exhibited more recency in their recall of lip‐read lists of digits than in their recall of graphically presented lists, indicating that such recency effects are not restricted to auditory perception or processing. Experiment 2 studied the effects of phonological and non‐phonological suffixes on good and poor deaf speakers' recall of lip‐read lists. The two groups performed identically, and whereas the phonological suffix impaired end‐of‐list recall, the non‐phonological suffix did not affect recency. Experiment 3 showed that both deaf and hearing subjects exhibited enhanced accuracy of end‐of‐list recall for moving, as compared with static, hand signs. It was concluded that deaf and hearing subjects did not differ in the way they remembered the visual stimuli presented, and that lip‐read information was coded phonologically by deaf subjects, irrespective of their articulatory skill. Further, movement of stimulus features makes an important contribution to enhanced recency effects in the recall of visually presented lists for both deaf and hearing subjects.
