Abstract

Twelve Ss participated in a study investigating redundant and orthogonal stimulus dimensions in partial reports (PRs) from visual immediate (iconic) memory. Each S was tested under four conditions: PRs on the bases of size, color, and letter vs. digit, and whole report (WR). Each of the three selection criterion dimensions occurred as the only varying dimension, and with each of the other two dimensions varying redundantly and orthogonally with it Results indicated PRs significantly better than WR for size and color only, supporting the contention that a simpl physical characteristic is necessary for a PR effect. Differences between reports from redundant and orthogonal stim ulus groups were significant for both irrelevant dimensions within each of the three selection criteria.
