The claim that patients with schizophrenia lack sensorimotor facilitation proposed in Sevos et al. (2016) is based upon two non-significant effects reported in Experiments 1 and 2, which is problematic since the traditional null-hypothesis testing approach does not allow one to "accept" a null hypothesis. We develop a Bayesian analysis of these two results and argue that, at present, there is not much support for the null effects reported in the original study.

Abstract

The claim that patients with schizophrenia lack sensorimotor facilitation proposed in Sevos et al. (2016) is based upon two non-significant effects reported in Experiments 1 and 2, which is problematic since the traditional null-hypothesis testing approach does not allow one to "accept" a null hypothesis. We develop a Bayesian analysis of these two results and argue that, at present, there is not much support for the null effects reported in the original study.
