This paper reports a comparison of certain features of short-term memo
ry between deaf and hearing subjects. The features relate to linguisti
c material. The subjects' task was a serial recall of the stimuli. Sti
muli were presented as German words or signs on a screen. With differe
nt lists of similar stimuli it was possible to determine the code used
in short-term memory. Both deaf and hearing subjects used primarily a
phonological code. The memory span of these groups differed significa
ntly: the hearing subjects were able to reproduce 1.2 items more than
the deaf. A further aspect of the results refers to the semiotic statu
s of oral movements in German Sign Language. We found chat this compon
ent is processed together with the manual component of a sign, which i
ndicates a difference between this language and American Sign Language
, excluding a direct comparison between both languages.
