Kobayashi, Y., Matsushita, S. & Morikawa, K. (2017). Effects of Lip Color on Perceived Lightness of Human Facial Skin. i-Perception, 8(4): 1–10. doi: 10.1177/2041669517717500

In this study, there was an error in processing data from one participant in Experiment 2 on page 5. Correcting the data resulted in slight changes in the text on page 6, line 7 under “Result” section and

The updated text on page 6 and Figure 3 should read and appear as:

A one-way repeated measures analysis of variance showed that the main effect of lip color was significant, F(3, 57) = 3.04, p = .036, ${\eta }_{\text{p}}^2$  = .14. However, post hoc t tests using Holm’s method (Holm, 1979) showed no significant differences between the original face and the other three conditions (original vs. redder lips: t(19) = 1.25, p = .456, d = 0.20; original vs. lighter lips: t(19) = 1.68, p = .549, d = 0.29; original vs. darker lips: t(19) = 0.747, p = .464, d = 0.09). Regarding sex differences, neither main effect of sex nor interaction between sex and lip color was significant (p = .918 and p = .910, respectively).

Unlike Experiment 1, effects of lip colors were not observed in Experiment 2. This shows that the lightness-inducing effects of lips on facial skin stem largely from holistic processing.
