Neurophysiological indicators of internal attention: An electroencephalography-eye-tracking coregistration study.

ABSTRACT:

Introduction

Many goal-directed and spontaneous everyday activities (e.g., planning, mind wandering) rely on an internal focus of attention. Internally directed cognition (IDC) was shown to differ from externally directed cognition in a range of neurophysiological indicators such as electroencephalogram (EEG) alpha activity and eye behavior.

Methods

In this EEG-eye-tracking coregistration study, we investigated effects of attention direction on EEG alpha activity and various relevant eye parameters. We used an established paradigm to manipulate internal attention demands in the visual domain within tasks by means of conditional stimulus masking.

Results

Consistent with previous research, IDC involved relatively higher EEG alpha activity (lower alpha desynchronization)
