Short-term memory recognition search in aphasics.

A nonverbal short-term memory (STM) recognition task was administered to eight matched pairs of normal and aphasic subjects. Computer-controlled apparatus presented a stimulus list of two, four, and six digits, followed by a single digit, and recorded the amount of time required for subjects to indicate whether the single digit was In or Out of the stimulus list. Response latencies were signifi...

Phonological transformations in Spanish-speaking aphasics.

Thirty-seven aphasic patients whose native language is Spanish were divided into four groups: (1) Broca's, (2) Wernicke's, (3) Conduction, and (4) Anomia. Phonological errors produced on repetition and object-naming tasks were analyzed in terms of type of transformation and degree of similarity between target and errors in terms of shared distinctive features. Segmental transformations were of ...

Making non-fluent aphasics speak: sing along!

A classic observation in neurology is that aphasics can sing words they cannot pronounce otherwise. To further assess this claim, we investigated the production of sung and spoken utterances in eight brain-damaged patients suffering from a variety of speech disorders as a consequence of a left-hemisphere lesion. In Experiment 1, the patients were tested in the repetition and recall of words and...

Training with cognitive sequences improves syntactic comprehension in agrammatic aphasics.

A major open question in cognitive neuroscience concerns the modularity of language: does human language rely, in part, on neural processes that are not language specific? Such reliance would predict that learning should transfer between non-linguistic and linguistic domains via this common neural basis. To test this prediction, we studied effects of non-linguistic cognitive sequence training o...
