title: Negative recency and measurement of primary memory.
abstract: The technique of Waugh & Norman (1965) is widely used in measuring the capacity of primary memory. Watkins (1974) has proposed a modification of the technique which takes into account registration failure. A further modification is proposed which takes into account findings of negative recency in delayed recall.
