One in Nature: "Illusory perceptions of space and time preserve cross-saccadic |perceptual continuity," Kielan Yarrow, Patrick Haggard, Ron Heal, Peter Brown, John C. Rothwell

SUMMARY: When voluntary saccadic eye movements are made to a silently ticking clock, observers sometimes think that the second hand takes longer than normal to (...)
