Athletes demonstrate an advantage in unconscious processing under working-memory load specifically within sport-related domains.

A growing body of evidence indicates that unconscious priming requires attentional resources, including high-level cognitive resources such as executive attention. However, the generalizability of this finding remains unexplored. Specifically, it remains unclear whether unconscious priming in skilled athletes, who are widely considered to possess advantages in unconscious processing, is limited by executive attention, and whether such advantages transfer to non-experiential domains remains debated. This investigation seeks to address this research gap through two dual-task experiments utilizing a mixed experimental design, attempting to elucidate the characteristics of unconscious priming under working-memory load in experienced athletes. One hundred and twelve participants, half of whom were elite table tennis athletes, completed a dual-task paradigm combining an N-back task with a masked priming task. In Experiment 1, the stimuli in the priming task were unrelated to sports scenarios, whereas in Experiment 2, they were sport-related. Mixed-effects ANOVAs, incorporating within-subject, between-subject factors and between-experiment factor, were conducted to analyze behavioral data. The results showed that in Experiment 2, athletes displayed a significantly larger unconscious priming effect under working-memory load compared to non-athletes (η
