Lethal moves

How does it work and what is it for? Two explanations have been offered. Yarrow et al. hypothesized that it serves to create perceptual continuity across saccadic eye movements during which visual sensitivity is largely reduced, mainly due to saccadic suppression. Rose’s and Summers’ demonstration of chronostasis without eye movements, however, raises a question about this. The time perception literature suggests that the state of arousal produced by an abrupt stimulus change may be sufficient to transiently speed up the internal clock and therefore lead to an overestimation of duration.
