The study was designed to determine whether outer-directedness, measured by glances at E during object assembly tasks administered according to the Turnure and Zigler (1964) procedure, predicts changes in preschoolers' Binet IQs over 6 months. With MA as a covariate to control for the small but significant relationship between glances and developmental level, an ANOCOVA showed a significant interaction resulting from increases in the IQs of non-outer-directed Ss and declines in the IQs of outer-directed Ss. Glances at E's puzzle while S assembled his own were unrelated to glances at E or to IQ changes, but, unlike glances at E, were significantly related to improvements in performance from puzzle 1 to puzzle 2.
