Comment on "Differential Effects of the Temporal and Spatial Distribution of Audiovisual Stimuli on Cross-Modal Spatial Recalibration".

Bruns et al. (2020) provide new research that suggests that the ventriloquism after-effect (VAE: an enduring shift of the perceived location of a sound toward a previously seen visual stimulus) and multisensory enhancement (ME: an improvement in the precision of sound localization) may dissociate depending on the rate at which exposure stimuli are presented. They reported that the VAE, but not the ME, was diminished when exposure stimuli were presented at 10 Hz rather than at 2 Hz. To the authors, this suggested that different neural structures underlie the VAE and ME. In our view, however, this needs to be tested more extensively because alternative and simpler explanations have not yet been checked.
