Abstract:
The present study aimed at investigating cognitive abilities of typical adults and older adults with normal hearing using P300 event related potential. The P300 measures (both latency and amplitude) did not differ significantly across gender. The P300 latency was found to increase with age, whereas the P300 amplitude reduced significantly with age except in the case of 60-70 years age group. Overall, the P300 measures reflected the ageing effect. Further, the choice of P300 which uses evoked potential (objectively extracted) and language insensitive stimuli can be made to evaluate cognitive linguistic functions in individuals with impaired communication abilities from different linguistic backgrounds.
