Changes occurring in 41 5-11 yr old girls' performance levels on Euclidean geometric operations tasks were related to changes in forms of their drawings of 2 anticipated rotation movements over a 3-yr interval. Changes in both operatory and imagery performance followed a progressive, orderly sequence over time. Patterns describing changes in relations between performances on the 2 measures predominantly showed a stepwise progression in which Ss' operatory developments outpaced developments in corresponding imagery forms, followed by periods in which developments in imagery caught up to Ss' current operatory levels. Patterns showing imagery developments leading operatory developments at any point in time were relatively infrequent. Results are interpreted as support for the Piaget et al (1960) hypothesis that children's conceptions of Euclidean space underlie their representations of movements.
