Table 11 summaries of Level Mixture changes showed that "For low internal disequilibrium subjects in the +1 and +2 conditions, however, the trend was reversed; there were increases in Level Mixture from pre to posttest" and from pre to delayed posttest, consistent with nontransitional subjects becoming more transitional.

"Among middle and high internal disequilibrium subjects in the +1 and +2 Conditions taken together, the trend was a decrease in Level Mixture, both from pre to posttest and from pretest to delayed posttest," consistent with consolidation at a higher level.

"Among middle and high internal disequilibrium subjects in the +1 and +2 Conditions taken together, the trend was a decrease in Level Mixture"

Discussion¶

Related Claims¶

• Higher internal disequilibrium is associated with more regressive (minus) changes as well as more progressive changes — related
• Higher internal disequilibrium (Level Mixture) predicts Modal Level advance but not Map Drawing Mean improvement — related
• One-level and two-level external disequilibrium conditions did not differ significantly, and all Modal Level advances occurred to exactly one level above the subject's mode — related
• Training with maps one or two levels above the child's current level produces greater map drawing advance than training with maps at the child's own level — related
• Discrepant training conditions (+1/+2) provided limited evidence of greater transfer to related spatial reasoning tasks than own-level training — related
• Positive Bias (more non-modal responses above than below the mode) distinguishes subjects likely to advance in Modal Level from those likely to consolidate — related
• Conservation training stressing identity and reversibility improves conservation of quantity in nonconserving preschoolers — related
