What dimensions do young children's trait concepts have for the prediction of others' actions?

Research of the personality trait concepts in children, personal perception, and the Big Five theory has shown that young children begin to understand trait concepts from about 5 or 6 years of age, and form the Big Five concept that has same dimensions as that of adults by the upper grades in elementary school. However, the developmental process was not clear. This study examined hypotheses about the developmental process based on the Big Five theory. In Study 1, 5- and 6-year-old children (8 boys, 10 girls) were presented with action scenes of protagonists who showed personality characteristic of one of the Big Five dimensions, and predicted the protagonists' actions in similar scenes. It was found that 5-years-olds were successful in predicting the dimensions of Extroversion, Attachment, and Intellect, and 6-years-olds in predicting those and Controlling as well. In Study 2 (participants: 6 boys, 9 girls), however, it was suggested that their predictions for these dimensions were mostly based on a general dimension of Goodness.
