<p>Perceptual similarity is a cornerstone for human learning and generalization. However, in assessing the similarity between two stimuli differing in multiple dimensions, it is not well-defined which feature(s) one should focus on. The problem has accordingly been considered ill-posed. We hypothesize that similarity judgments may be, in a sense, metacognitive: The stimuli rated as subjectively similar are those that are in fact more challenging for oneself to discern in practice, in near-threshold settings (e.g., psychophysics experiments). This self-knowledge about one's own perceptual capacities provides a quasi-objective ground truth as to whether two stimuli should be judged as similar. To test this idea, we measure perceptual discrimination capacity between face pairs, and ask subjects to rank the similarity between them. Based on pilot data, we hypothesize a positive association between perceptual discrimination capacity and subjective dissimilarity, with this association being importantly specific to each individual.</p>

The authors have clearly invested significant effort into the revision process, and the manuscript is now in much better shape. I sincerely appreciate their hard work. , Haiyang Jin suggested: Minor points: , Haiyang Jin suggested: 1. I would suggest including references to support the definition of “metacognition” (Line 72) and the hypothesis (or perhaps assumption) that “similarity judgments involve a type of implicit metacognition” (Line 73). , Haiyang Jin suggested: 2. It is possible to directly evaluate the significance of the null result. Authors may refer to equivalence tests (Lakens et al., 2018). , Haiyang Jin suggested: Reference: , Haiyang Jin suggested: Lakens, D., Scheel, A. M., & Isager, P. M. (2018).
