Temporal decoupling. In Experiment 1, observers reported which of two clocks appeared to be more advanced. A 20-Hz adaptation caused a clock in an adapted region to appear shifted forward in time by about 10 ms. No such effect was observed for 5-Hz adaptation. (A) Psychometric functions for individual subjects following 5- (red) and 20-Hz (blue) adaptation. (B) Points of subjective equality. Error bars on individual subject data indicate 95% confidence intervals; error bars on mean data indicate standard errors.
