Abstract/OtherAbstract:
Our sense of relative timing is malleable. For instance, visual signals can be made to seem synchronous with earlier sounds following prolonged exposure to an environment wherein auditory signals precede visual ones. Similarly, actions can be made to seem to precede their own consequences if an artificial delay is imposed for a period, and then removed. Here, we show that our sense of relative timing for combinations of visual changes is similarly pliant. We find that direction reversals can be made to seem synchronous with unusually early colour changes after prolonged exposure to a stimulus wherein colour changes precede direction changes. The opposite effect is induced by prolonged exposure to colour changes that lag direction changes. Our data are consistent with the proposal that our sense of timing for changes encoded by distinct sensory mechanisms can adjust, at least to some degree, to the prevailing environment. Moreover, they reveal that visual analyses of colour and motion are sufficiently independent for this to occur.
