Reviews: Perceiving the arrow of time in autoregressive motion

Originality: To the best of my knowledge, conducting human psychophysics and comparing their performance to computational models has not been done for the precise problem formulation examined by the authors. However, the authors did not describe previous work on anorthoscopic perception, which has examined similar question (how do people perceive a figure that is revealed to them through a slit moving over it over time? Is the constructed perception equivalent in each order?) and has a long history dating back to Helmholtz. For a good review, see Rock, I. (1981). Quality: The human experiments and computational modeling are well conducted.
