Student teachers were asked to read a description of a girl who had acted out a bit in class (talking when she wasn't supposed to). A picture, supposedly of the girl, accompanied the written description. For some of the student teachers, the picture was of an attractive little girl. For other student teachers, the picture was of an unattractive little girl. Student teachers then rated the girl on a seven-point scale indicating the extent to which they thought she had a behavior problem in class.
