Abstract:	This commentary addresses the discrepancies in measuring and interpreting frontal alpha asymmetries (FAAs) as electrophysiological makers for motivation and affect identified by a recent review (Sabu et al., 2022). Specifically, the authors aim to identify under which circumstances FAAs yield meaningful results and index emotional or motivational states. Thus, they categorize and review the stimuli used in the literature into five categories being less to more effective in eliciting emotions: (1) images and sounds, (2) videos, (3) real cues, (4) games, and (5) other tasks. As a result, the potency to elicit pronounced FAAs seems to vary as a function of modality with planar 2D stimuli being less potent to elicit emotions as opposed to more realistic and engaging stimuli. Nevertheless, no category induces FAAs consistently, hence casting doubt on whether FAAs are a universally applicable measurement for emotion and motivation solely dependent on the potency of the stimulus. I argue that potency as an ordinally scaled factor does not account for FAAs because different stimuli types belong to different categories. Hence, if FAAs carry meaning, they might be specific to the domain in which they occur.
