N2 - Perceived regularity among events in the environment allows predictions regarding the "when" and the "what" dimensions of future events. In this context, one crucial question concerns the impact and the potentially optimizing effect, of regular temporal structure on the processing of "what", or formal, information. The current study addresses this issue by investigating whether temporal and formal structure interact during early stages of sensory processing, and by relating the respective findings to the concept of a predictive bias in brain function. Analyses were performed on two components of the auditory event-related-potential of the electroencephalogram, namely the P50 and the N100.
