Abstract

While many studies have linked prediction errors and event related potentials1

at a single processing level, few consider how these responses interact across

levels. In response, we present a factorial analysis of a multi-level oddball task

– the local-global task – and we explore it when participants are sedated

versus recovered. We found that the local and global levels in fact interact.

This is of considerable current interest, since it has recently been argued that

the MEEG response evoked by the global effect corresponds to a distinct

processing mode that moves beyond predictive coding. This interaction

suggests that the two processing modes are not distinct. Additionally, we

observed that sedation modulates this interaction, suggesting that conscious awareness may not be completely restricted to a single (global) processing

level.
