Visual short-term memory in the hearing and the deaf.

Tested 9 deaf and 9 normal 15-27 yr olds on their ability to report letters, shapes, and nonsense figures from a tachistoscopic presentation. Deaf Ss performed worse than hearing Ss on recall of figural information, thereby supporting a linguistic coding hypothesis. However, there was no difference between the groups on position information, and letter confusions were primarily visual in both groups. Findings suggest that more attention should be given to visual short-term memory in theoretical models of memory. Formation of the icon was apparently not affected by a linguistic deficit, since effects of stimulus duration and type of viewing (continuous vs interrupted) were similar in both hearing and deaf Ss. Significant positive correlations which were found between deaf Ss' school reading scores and their tachistoscopic scores were not interpreted as support for a linguistic coding hypothesis, but rather as support for the notion that the memory skills tested in the experiment may underlie reading ability.
