Abstract

We investigated word repetition and learning in five patients with semantic dementia,
predicting reduced semantic effects (e.g. imageability) and preservation of lexical effects
(e.g. frequency). Additionally, we investigated whether primacy effects in serial
repetition would be reduced, consistent with other semantically- impaired populations
(Martin and Saffran, 1997). All participants showed reduced imageability effects, while
only one showed a word frequency advantage. Two patterns of serial position emerged:
(1) poor recall of initial list items and (2) a typical pattern of better recall of initial and
final items. Failure to recall initial items was associated with poor list learning across
repeated trials.
