Abstract: | 20 normal subjects were submitted to seven auditory ERP paradigms in which they were required to count regularly presented cliks (A1, A2, A3), cliks presented in pseudorandom order (B) and in which they had to discriminate relevant from non relevant stimuli characterized by side of provenience (C1, C2) or intensity difference (D). In paradigms C and D a P 300 component was evoked. Age was significantly correlated with P 300 latency only in paradigm D. There was a significant relationship between differences in subjective feelings of difficulty or engagement in performing the counting tasks in C and D and P 300 latency. |
