This study used two different contents of the fantasy-reality distinction tasks to examine about more precisely fantasy-reality distinction task. The different contents were color of picture (color print or monochrome print) and instruction. Participants were 3 to 5-year olds preschoolers. The results were follows. (1) It was suggested that it is preferable to use the picture printed monochrome because there is a possibility that young children's understanding of the fantasy-reality distinction is influenced by color of picture. (2) As for the instruction about the content of the presented picture, it was suggested that it is preferable to instruct children including "happen in real life" and "happen only in the picture book"
