Discussion The results of Experiment 1 seem to indicate that binocular disparity does not contribute to the fast recognition of visual scenes, if anything, a nonsignificant trend for worse recognition of stereo pictures emerged, a result which is strikingly different from the observation of Liu and colleagues (2000) , who found that stereo produced a small (2.5%) enhancement in the recognition rate of faces with a viewing time of 1.5 s and the observation of Valsecchi and Gegenfurtner (2012) , who found a significant improvement in the long-term memorization rate when observers viewed the same forest pictures for 7 s.
