Here we studied how typically developing Finnish speaking children process non-verbal spectral and temporal acoustic stimuli with speech like elements. Twelve typically developing 5 - 6–year old children participated in the study. Auditory processing skills were assessed by using brain event-related potentials (ERPs). Three sine tone stimuli were presented in a passive oddball/ MMN paradigm. The standard stimulus (80 %) was a tone pair with a 150 ms within-pair interval (WPI), the spectral deviant stimulus had a pitch change in the 2nd tone, and the temporal deviant stimulus had a rapid rhythmic change including a third tone (all parts with 50 ms WPIs). Temporal principal component analysis (tPCA) was used to extract ERP responses of interest. The 2nd tone with the pitch change in the spectral deviant stimulus generated fronto-central negative response at peaking at 176 ms (from the 2nd tone onset) with a reversed polarity below Sylvian fissure. This response overlapped with N250 for the standard stimulus but emerged earlier, suggesting mismatch negativity (MMN) for spectral change in temporally complex stimuli in pre-school aged children at about the same time window as in adults. The temporal deviant stimulus generated a response pattern reflecting the temporal structure of the stimuli. The topographical distribution was similar to that of the response for spectral change but the amplitude was lower, suggesting obligatory stimulus dependent temporal processing in children.
