Abstract
Twenty-eight normal subjects heard seven digits masked by noise, and repeated either (a) the first three digits, (b) the last three digits, (c) all seven digits, or (d) all seven digits after saying “zero.” Over the range of intelligibility tested (approximately 60% to 100%), accuracy of seven-digit repetition improves linearly as accuracy of three-digit repetition improves, with the average slope being near 1.00. These data were interpreted to mean that the decrement in intelligibility that results from masking is accompanied by an added decrement in short-term memory.Keywords
