Abstract
The present experiment examined the influence of repetition on iconic memory using the Sperling (1960) procedure. It was assumed that the whole-report procedure would estimate only information available from a somewhat more permanent memory system than the icon, while the partial report would estimate both that information and the information available in the icon. The difference between the whole and partial report was assumed to measure information available only in the icon. Across a series of 160 displays one particular display occurred half the time (80 repetitions). The results indicated that the repetition influenced recall from the more permanent memory system assessed by whole report, but had no influence on the information available from the icon (partial report minus whole report).
