The major goal of this study was to determine whether young children appreciate that
one effect of using a display rule may be to create a false belief in another
person. Fourand 6-year-old children listened to stories in which it would be
appropriate for the protagonist to really feel a negative emotion. In half of the
stories a reason was given for the protagonist to hide the way he or she really felt
(the discrepant condition) from the other story characters; the other half
contained a reason for the protagonist to show the other story characters how he or
she really felt (the nondiscrepant condition). Subjects were asked to say
how the main character would really feel, how the main character would look on his
or her face, and how other characters in the story would think the protagonist felt,
and to justify their answers. The results indicated that 6-year-old children were
more accurate than 4-year-old children in judging that real and apparent emotion
would not coincide in the discrepant condition and that other story characters would
be misled as a result. Six-year-olds also offered more correct justifications of
their responses in both story conditions. The findings are related to recent
investigations of children's understanding of the appearance-reality distinction and
the development of children's knowledge about how to create a false belief in
another person.
