Understanding of Proportion as Embodied in the Concept of Fullness. An Investigation into Bruner's "Modes-of-Representation-Conflict Hypothesis"
McWhirter, Elizabeth P.
Contemporary Educational Psychology, 3, 3, 205-31, Jul 78
This replication study negates Bruner's finding that older subjects (age 15 and adult) understand the mathematical concept of ratio as exemplified by comparing judgments of fullness in pairs of glasses differing in height, diameter, and water volume. Weaknesses in Bruner's design and procedure that explain the discrepancy between the two studies are discussed. (Author/CP)
