(a) Pearson correlations (and the relevant p values) between the strength of the S parameter (as an index of lexical-semantic processing in production) and various lexical and semantic comprehension scores, in a sample of 103 aphasic patients. Reported P values are corrected for the number of tests and are comparable to α = 0.05. (b) Pearson correlations (and their relevant p values) between the strength of the P parameter (as an index of lexical-phonological processing in production) and various input processing measures, in a sample of 103 aphasic patients. Reported P values are corrected for the number of tests and are comparable to α = 0.05.
