Relative influence of the compression cue in Experiments 4 and 5. (A) Results of Experiment 4, averaged over N = 14 subjects. Compared to a baseline measured in session 1 where the local stimulus context was regular on all trials, the influence of the compression cue was significantly lower in regular context trials of the last three sessions which were intermixed with random context trials. In addition, it was significantly lower in random context trials compared to regular context trials of sessions 2 to 4. No significant changes were observed in a control group of 14 subjects who viewed only regular context trials in all experimental sessions. (B) In Experiment 5, subjects (N = 15) made slant judgments for the same stimuli as in Experiment 4, but the 9 stimuli that made up a trial in Experiment 4 appeared sequentially. The influence of the compression cue was significantly higher for test stimuli embedded in a sequence of regular context stimuli than for test stimuli embedded in a sequence of random context stimuli, and highest in session 1, where there were only regular context stimuli.
