Reaction times at each of the 4 JOL levels are given for the New condition, the A-B A-C condition, and the A-B A-B condition, for left, center and right panels on the top. A JOL of 1 indicates that the participant thought they did not know the response while a JOL of 4 indicates that they thought they knew it. On the bottom are the proportion of responses given at each JOL level, shown by the bars, and proportion correct at each JOL level, shown by the diamonds, with the data from the New condition on the left, from the A-B A-C condition in the center, and from the A-B A-B condition on the right. All data are from Experiment 1.
