The burgeoning prominence of esports underscores its increasing relevance in sport and performance psychology. To enhance its integration into scholarly discourse, established cognitive research paradigms should be applied. In this study, we focused on first-person shooter esports, identifying specific variables unique to this domain and examining their impact on quiet eye (QE) duration—an indicator strongly correlated with successful performance. Using eye tracking equipment, we analysed gaze data related to the QE, the final fixation point preceding a motor response. Our pilot sample (n = 9) participated in three block trials exploring the effects of environmental clutter, target differentiation, and target prioritization on QE duration. Paired t-tests compared mean QE duration between experimental tasks and control trials with single targets. While trend effects of environmental clutter and target prioritization were observed, none reached statistical significance. These findings echo certain aspects of existing esports literature, particularly regarding the reduced prominence of QE in scenarios involving multiple targets. Acknowledging study limitations, we offer recommendations for future research to deepen understanding of cognitive processes and performance outcomes in esports.
