Comments on “No self-advantage in recognizing photographs of one’s own hand” (Holmes, Spence, Rossetti Exp Brain Res., 2022). What exactly is meant by "self-advantage effect" in implicit recognition of one's hand?

I read with great interest the article by Holmes, Spence, and Rossetti in this issue of Experimental Brain Research. The authors conducted 5 experiments to answer the question, “is there a self-advantage in the recognition of hand images in implicit and explicit tasks?” (page 2). A clear distinction between implicit and explicit tasks could have helped the reader to immediately understand that only one experiment (Experiment 1) investigated the self-advantage effect found in previous studies, wherein participants were not asked to explicit recognize their own hand (Implicit task).
