Abstract: The study explored 6 to 8 years old children's understanding of the phenomenon that differed in observer's expectation leading to different interpretations to the same ambiguous information.The factors influencing the observer's expectation include perceptual experience,knowledge level,prior experience,and social prejudice were manipulated,and participants were required to predict the observer's interpretations of restricted view drawings or ambiguous actions.The results indicated that 6-year-olds could only partly understand that observer's social prejudice influence their interpretation of actor's behavior,and they could not understand that prior perceptual experience and knowledge level influence observer's interpretations of visual stimuli,they could not understand that previous experience influence how observer interprets actor's behavior either.7-year-olds could understand all the factors influencing expectations,except knowledge level.8-year-olds could understand difference in interpretations due to a variety of observer's expectations.They seemed to have stable interpretive theory of mind,though they still did not reach the fully mature understanding of the complex issue of interpretation.

Key words: interpretive theory of mind, observer's expectation, restricted view drawings, ambiguous action
