Cognitive and communicative function : The effects of chronological age and "handicap age"

摘要: Abstract Three classes of cognitive tests (short-term memory, long-term memory access/recall, and verbal ability) one class communicative (visual speech-reading) were administered to 49 hearing-impaired 69 normal hearing subjects, varying in age between 23 75 years. It was found that when dB-loss “handicap age” partialled out, the negative effects ageing remained: Speed accessing alphanumeric symbols from as rehearsal speed correlated substantially with chronological age. Discriminant analyses revealed a communality discrimination old young skilled less speech-readers: Visual decoding skill constituted common discriminators. Departing this result, an age-dependent componential model visual speech-reading is delineated. particular reference assumption temporally early lexical access system crucial lip movements.
