Links Between Short-Term Memory and Word Retrieval in Aphasia

Explore the relationship between anomie and short-term verbal memory in the context of an interactive processing model of the activation language.

Method

24 individuals with immediate memory impairment in word series completed an image name task and a word pair repetition task

Correlations between verbal STM and word retrieval errors in image nomenclature task were examined

Limitations and directions

Focuses on the pattern of temporal linguistic activation during the intermediate step between listening to a pair of words and producing it

Several modifications should be considered

Limit the amount of time the image is present on the screen

Limit the assigned response time. Allow the image to be present only in brief

General debate

It is suggested that word production, measured by the name of the image, depends more on the force of representation

Language representations can support both word retrieval and the repetition of word pairs

The spread of language activation follows different time courses in these two tasks.

Concluded

Word retrieval and verbal STM tasks are probably based on a partially shared temporary language activation process.

Representations of language have the potential to inform and influence clinical practice, eventually leading to the creation of generalizable, impairment-based treatments for aphasia.
