Abstract

Recent studies have postulated that the temporal order (TO) of two successive events can be correctly identified if they are separated by an inter-stimulus interval (ISI) of at least 30 ms duration. Using Auditory Evoked Potentials, we tested 21 students for the cortical activation associated with TO detection of two successively presented tones in either ‘easy’ (ISI = 60 ms) or ‘difficult’ (ISI = 10 ms) conditions. The amplitude of P2 component was related to difficulty of TO perception and was significantly higher in ‘difficult’ than ‘easy’ condition. Moreover, in ‘difficult’ condition the correlation analyses revealed a negative association at both Fz and Cz electrodes between P2 amplitudes and the correctness level. Correct responses in this condition were accompanied by lower P2 amplitudes than the incorrect ones.
