After completion of each go/no-go block of trials, a block of trials requiring preference ratings was presented. Pictures in this second rating task were identical to those in the preceding go/no-go block. The order of the pictures was also the same as that in the go/no-go block. After 10 practice trials for each go/no-go task and rating task, participants performed eight blocks of go/no-go trials and rating trials, respectively. Thus, each block of 10 go/no-go trials was followed by a block of 10 rating trials.
