Figure 1. Scrambling manipulation and unscrambling analysis.

Figure 1

A: Construction of interleaved movie stimulus. A continuous 6-minute scene from the film Children of Men was divided evenly into short clips at each of five durations: 0.5 sec, 1 sec, 2 sec, 5 sec, and 30 sec. In the cartoon, each rectangular box depicts a movie sequence of 0.5 sec long, so that a group of two boxes represents a 1-sec clip, a group of four boxes represents a 2-sec clip, and so on. Clips of all durations were interleaved in random order to create a 30-minute movie. B: Unscrambling analysis. For each clip duration (shown here for 0.5 sec), eye-movement time courses (horizontal and vertical) were extracted, and rearranged to match the order of the corresponding clips in the intact movie. Covariance was computed between the unscrambled eye-movement time courses and those for the intact movie.
