Third-year summary of IES Arrow-Dot longitudinal comparisons in preschool children.

Three samples of preschool children in a suburban nursery school and kindergarten were administered the IES Arrow-Dot test at the beginning and end of three successive school years. Trends for declining Impulsivity and similar baselines for this variable were found in all three samples. Results for Ego and Superego scores showed variation. These findings support the effective use of this instrument with preschool children. Future investigations within varying educational environments are suggested to delineate further patterns of preschool personality development and integration.
