All of the subjects freely consented to having their session
videotaped. At the conclusion of the experimental trials, an
independent observer
was asked to rank each child in nine specific
categories (see Appendix C), based on a combination of the child's
behavior in the video, and the written responses to the
questionnaires. The observer did not know the hypothesized
relationships between any of the categories, but may have inferred
a correlation on her own. This independent assessment provided a
quantification of each child's behavior.
