Description
Summary:Phonological processing was investigated in nine Broca's aphasics. A receptive phonological task examined knowledge of phonotactic rules. Three lists of “word” pairs, phoneme sequences, were constructed such that one member was possible in English and the other was not. The lists varied in distance from English or phonemic structure (CCVC vs. CCVCC). Following auditory presentation, the aphasic was required to indicate which of the two “words” was possible in English. The productive task was an articulation test for monosyllabic and polysyllabic words. The high positive correlation between receptive and productive scores suggested that, rather than motor speech sequencing problems being exclusively involved, more general phonological-articulatory processes were disrupted. Several hypotheses were advanced to describe the nature of this disruption.
