highly significantp <0.0005
Reward probability, reward magnitude and their interaction each had a highly significant influence on subject choices (one-sample T-test on regression coefficients, all T(17)>4.6, all p <0.0005), but importantly there was no significant difference in these influences between the two types of trial (paired T-test on regression coefficients between trial types, all |T(17)|<1.52, all p >0.14).
