	The combination of strong movement in ML and an idiosyncratic response to iconicness in KU may be driving the reduction in NAcc activation that we witness when increasing from n=22 to n=18. Certainly, from the individual maps we do not see as strong a contrary response in the insula. However, the direction of activity seems to be the same in both subjective individual maps for KU and ML, leading to some confusion as to how they can drive down the population-rating maps so efficiently while leaving the subjective rating maps intact.

			The fMRI group is substantially different in that iconicness is not a predictor of giving (p=0.07) while it is very significant in the behavioral population (n=40). This is a strange idiosyncrasy of the populations, and it may be that with a larger group we would see NAcc response rise to prominence. Nucleus accumbens activation may also be dependent on pro-environmental attitudes, although using 3dregana, this was not found (however, higher pro-environmental attitudes predict higher insula response to destructive land uses).

 Subject ML had low engagement with the task in addition to high motion. Upon removing her from the group maps, however, no real difference was seen from the N=22 maps. It remains to be seen whether removal of subject KU would improve the maps: because she has strong ventral striatal deactivation precisely where we see activation in others, she may be having a fairly strong effect on blocking the NAcc reaction to iconicness.
