As a result, the main effect of Devaluation was highly significant (F(2,20) = 68.0, p<0.0001).
As a result, the main effect of Devaluation was highly significant (F(2,20) = 68.0, p<0.0001).
Responding was slightly higher in the group that received DMSO alone on this occasion, as indicated by the main effect of Drug approaching significance (F(2,20) = 3.3, p=0.0589).
Consistent with these observations, the critical Devaluation X Drug interaction approached significance (F(1,12) = 4.0, p=0.0679), while the main effect of Devaluation (F(1,12) = 10.0, p=0.0081) but not of Drug (F < 1) reached significance.
(Indeed, despite this and the relatively small n's, there was a nonsignificant trend towards devaluation (p = 0.15) in this group).
