Forty-four normal adults were screened on the rod and frame test and two groups, each consisting of seven persons who made relatively large errors, were given training specifically designed to improve their performances. The first group received instructions on how to resist the influence of the tilted frame and how to use bodily cues. The second group received the same training, plus feedback and discussion of each judgment. The first group did not improve. The second did, but the improvement was transient and disappeared upon later retesting under standard conditions. Test-retest correlations within both groups were high.
