In addition, reaction times, omissions, and commissions were comparable across all conditions. The statistical analyses revealed no differences between the three conditions in terms of amplitudes and latencies of the N2d and P3d components. The N2 and P3 components of the difference waves (N2d and P3d) were used for statistical analyses. From these ERPs, the N2 and P3 components were specifically analyzed since previous studies have shown that these components (and particularly the Go-NoGo difference waves) are strongly associated with inhibitory functions.
From the EEG data, event-related potentials (ERPs) were calculated for the Go and NoGo trials. In addition, we collected reaction times, omissions, and commissions in response to the Go and NoGo stimuli. Participants completed a standardized cued Go/NoGo task during three different conditions while an EEG was recorded (1: with no background music, 2: with relaxing, or 3: with exciting background music). In this study, we investigated the influence of background music on executive functions (particularly on inhibitory functions). The influence of background music on cognitive functions is still a matter of debate. 2Dynamics of Healthy Aging, University Research Priority Program (URPP), University of Zurich, Zurich, Switzerland.1Department of Neuropsychology, Psychological Institute, University of Zurich, Zurich, Switzerland.
