Figure 6: The average number of combined aggression and health dangerous behaviors per participant in planned (closed circles) and unplanned (open circles) fading groups per month for six individual months prior to contingent skin-shock treatment (-6 to -1), during the first partial month of treatment (0), six individual months following treatment onset (1 to 6), and aggregate average monthly frequency data at 1, 2, 4, 8, and 15 years (multiples of 12 on the horizontal axis). Dashed lines indicate onset of fading and data labels indicate the number of participants receiving treatment at the end of each period.
