A repeated stimulus is judged as briefer than a novel one. It has been suggested that this duration illusion an example of more general phenomenon—namely expected less To test hypothesis, we manipulated high-level expectation through the probability sequence, regularity preceding stimuli in or whether violates overlearned sequence. We found perceived not reduced by these types expectation. Repetition stimuli, on other hand, consistently reduces across our experiments. In addition, effect repetition constrained to location stimulus. Our findings suggest estimates subsecond are largely result low-level sensory processing.
