Interpretations of Rod-and-Frame Test Scores: An Application of Pattern Analysis

Abstract

Rod-and-frame test data of 100 undergraduates were analyzed by a recently developed pattern analysis and several interpretations of their test scores were considered. Pattern analysis showed (a) that most subjects (about 65%) tilt toward the spatial position of the frame and (b) that some (about 30%) utilize two frame cues, i.e., the nearest to vertical side and corner of the frame. Tilting to the starting position of the rod and tilting away from the frame or the starting position of the rod were not viable interpretations.
