Figure 1
The chart presents box plots for the percentage of target behaviours achieved across sequential time periods. The horizontal axis lists baseline from minus 2 to 0 weeks, followed by token periods labelled 1 to 3, 4 to 6, 7 to 9, 10 to 12, 13 to 15, 16 to 18, 19 to 21, 22 to 24, 25 to 27, and 28 to 30 weeks. The vertical axis shows the percentage of target behaviours achieved from 0 to 120 percent. For the baseline period, the box spans from 4 to 46, with the median positioned near 20. For weeks 1 to 3, the box spans from approximately 18 to 98, with the median positioned near 60. For weeks 4 to 6, the box spans from approximately 30 to 92, with the median positioned near 55. For weeks 7 to 9, the box spans from approximately 18 to 82, with the median positioned near 45. For weeks 10 to 12, the box spans from approximately 25 to 80, with the median positioned near 40. For weeks 13 to 15, the box spans from approximately 28 to 85, with the median positioned near 45. For weeks 16 to 18, the box spans from approximately 15 to 82, with the median positioned near 40. For weeks 19 to 21, the box spans from approximately 20 to 75, with the median positioned near 45. For weeks 22 to 24, the box spans from approximately 15 to 88, with the median positioned near 35. For weeks 25 to 27, the box spans from approximately 22 to 80, with the median positioned near 40. For weeks 28 to 30, the box spans from approximately 15 to 95, with the median positioned near 50. Each box represents the interquartile range for the period, the horizontal line within each box represents the median, and individual data points show the distribution of observed values. Several token periods above the baseline are marked with an asterisk to indicate a statistically significant difference from baseline using a Bonferroni corrected p value less than 0.05.The percentage of target behaviours achieved during the baseline measurement (–2–0 weeks) and the period during which the tokens were given (n = 10). * indicates a significant difference from baseline. Bonferroni corrected p < 0.05
