I report a series of single case studies involving
an aphasic patient, H.G., which illustrates both the usefulness
and the limitations of cognitive neuropsychological models
and methods in aphasia rehabilitation. The first set of
experiments analyze H.G.'s pattern of performance
across lexical tasks in order to identify the loci of her
damage to the cognitive mechanisms underlying the tasks
of naming, comprehension, repetition, reading, and spelling.
The second set of studies evaluates her response to two
different types of treatment and identifies a few of the
variables that influence the effectiveness of treatment.
