Abstract: To investigate how stress affected implicit time perception, the participants, in the stress or neutral group triggered by movie clips, were required to judge whether abstract or concrete materials moved (forward, center, or backward) in the accelerating, constant, or decelerating conditions with different interval. The results showed that: in the constant and decelerating condition of the neutral group, the errors in the forward condition was greater than the one in the backward condition, the accelerating and constant conditions showed the same tendency in the stress group; the forward errors in the decelerating condition was smaller than the accelerating and constant conditions for the neutral group, while the stress group showed no differences among three dynamic conditions. The results indicated that stress violated implicit acceleration, reflecting the top-down interference affected implicit time, which supported cognitive model of time perception.

Key words: stress, implicit time, representational momentum, implicit acceleration
