Following the first preference rating, blocks of go/no-go trials and the second rating trials were administered; the go/no-go and rating blocks were alternately performed, as conducted in the previous studies (Kiss et al., 2008; Doallo et al., 2012). In each trial of the go/no-go task (Figure 1), a fixation circle was presented at the center of the display for 1200 ms, followed by the presentation of a picture for 300 ms (i.e., an inter-onset-interval between pictures of 1,500 ms). Participants were asked to press a space key as quickly and accurately as possible when the picture of a target category (gummy candy or rice crackers) was presented and to refrain from a key response when the picture of a non-target category was presented. Although picture duration was 300 ms, participants were allowed to respond during the 1,500 ms preceding the onset of the next picture. The next fixation circle and picture appeared regardless of whether the participant’s response was recorded. Each block of the go/no-go task consisted of 10 trials; 10 pictures, five for each stimulus category, were presented in a random order. The target category was instructed at the start of each block of trials and alternately changed from block to block. That is, in the half of the blocks the pictures of gummy candies were pared with a go response whereas in the remaining blocks the pictures of rice crackers were pared with a go response.
