Comment on Lubineau et al. (2023) 'Does word flickering improve reading? Negative evidence from four experiments using low and high frequencies'

In 2023, Lubineau et al. published an article [1] detailing several experiments carried out with dyslexic readers. These authors attempted to measure the change in reading performance under different reading conditions using flickering devices. Beyond the low-frequency systems which have nevertheless shown their interest for some cases, we restrict here our response to the high-frequency systems, i.e. electronically controlled glasses (Lexilens) and lamps, designed and built upon recent work by Le Floch and Ropars [2]. Lubineau et al. found no significant change in reading performance at either low or high frequencies and concluded that these devices provide no or minor benefits. Unfortunately, experimental misunderstandings and some methodological issues invalidate namely the main conclusion concerning the high frequency systems.
