Treatment of naming disorders: New issues regarding old therapies

I report a series of single case studies involving an aphasic patient, H.G. , which illustrates both the usefulness and the limitations of cognitive ne uropsychological models and methods in aphasia rehabilitation. The first se t 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 un derlying the tasks of naming, comprehension, repetition, reading, and spell ing. The second set of studies evaluates her response to two different type s of treatment and identifies a few of the variables that influence the eff ectiveness of treatment.
