This paper takes the form of a selective review of studies of therapy
for aphasic-naming disorders. There is a bias in the literature toward
s studies involving the use of semantic tasks (particularly word-to-pi
cture matching) in therapy and therefore this is reflected here. These
studies provide clear evidence that aphasic naming disorders can be r
emediated but it remains difficult to ascertain the precise mechanism
by which this improvement in naming is achieved. Several issues are di
scussed which pertain to this problem: the effectiveness of 'semantic'
and 'phonological' tasks; the relevance of each component of the ther
apy task to the outcome of the therapy; the relationship between the t
ype of deficit and the effectiveness of a task; when generalization ca
n be expected as opposed to (treated) item-specific improvement; and t
he importance of patient success on the task to the success of the the
rapy. Finally, the paper concludes with suggestions for the possible d
irection of further research into this important area.
