The stimuli and the procedure were identical to those of Experiment 1, with the following exceptions. In the go/no-go task, the pictures of gummy candies and rice crackers were sequentially presented as in Experiment 1. However, a digit depicted on a white placeholder (0.39 and 0.77° in width and height, respectively) was superimposed on each picture (Figure 1). Odd numbers (1, 3, 5, 7, or 9) were presented in half of the trials in a block, whereas even numbers (0, 2, 4, 6, or 8) were presented in the other half of the trials in the block. In a half of the blocks, participants were required to press a space key when an odd number was presented, whereas they were required to refrain from the response when an even number was presented. In the other half of blocks, the assignment of the target category to the type of response was reversed. The target category was alternately changed from block to block and the order was counterbalanced across participants. The combination of the category of digits and the category of pictures was fixed for a participant. For example, one participant, only odd numbers (or only even numbers) were presented on the pictures of gummy candies (or only pictures of rice crackers). This combination was counterbalanced across participants.
