The specific purpose of the research discussed was to develop an instrument which would permit assessment of individual and developmental differences in the acquisition of abilities to understand and utilize emotional and psychological facets of interpersonal behavior. Emotional insight was assessed in 81 male and female children between the ages of 6 and 13 years, using 12 stories that were presented in cartoon form, each on a 16 x 20 card. No conversation was depicted in the cartoon sequences; the number of frames varied from 9 to 11. Included in the frames were nonverbal cues indicative of an appropriate emotion and behavior which was based on the emotion. The stories varied in the degree of sophistication required to interpret them. After each child viewed a cartoon sequence, he was asked to tell the story twice, as the child saw it and as the other people in the story would tell it. After viewing all 12 sequences, each subject was given a Peabody Vocabulary Test. Results show that the technique permits assessment of individual developmental rates and sequences, as well as antecedents and consequents of emotional interpersonal insight. (DB)
