In studies that use subliminal presentations participants may become aware of stimuli that are intended to remain subliminal. A common solution to this problem is to analyze the results of the group of participants for whom the stimuli remained subliminal. A recent article (Shanks, 2017) argued that this method leads to a regression to the mean artifact, which may account for many of the observed effects. However, conceptual and statistical characteristics of the original publication lead to overestimation of the influence of the artifact. Using simulations we demonstrate that this overestimation leads to the mistaken conclusion that regression to the mean accounts for non-conscious effects. We conclude by briefly outlining a new description of the influence of the artifact, and how it should be statistically addressed. |
