Subjects performed a change detection task that measures iconic memory (Figure 1B; IC), fragile VSTM (Figure 1C; fVSTM), and visual working memory (Figure 1D; VWM) in a single experiment. In addition, after each change trial an identification display was shown that required subjects to identify the pre-change item. Here, we present the proportion correct on no-change trials (No-change performance) and the proportion correct on change trials (Change performance). In addition, we present the proportion of change trials where subjects correctly detected the change and identified the pre-change item (Detection and Identification), correctly detected the change without correct identification (Detection only), and correctly identified the change without change detection (Identification only). Reported values are averages (±SEM) for grayscale and color images apart.
