Figure 5.

Plots of every RT across the session for the lexical decision and item recognition tasks.

The numbers on the left are the subject numbers in the order analyzed. The vertical thick (double) lines in the middle of the plot represent the point at which the task switched from lexical decision to item recognition. The thin vertical lines represent blocks of trials (when they do not align, the subject did not finish all the trials). The dashed horizontal line is at 300 ms and serves as an approximate way of identifying fast guesses (an RT below this is almost certainly a fast guess, RTs above but close to it may be fast guesses). Long RTs greater than 1300 ms are replaced by 1300 ms (this was done so that the focus could be on the shorter RTs).
