Effects of association and repetition in memory for temporal order.

Temporal order recognition memory has been examined previously with tasks involving a recency judgment between a pair of items in a preceding string. Recency judgments are impaired when the earlier item is repeated. The present study employed the comparative recency judgment paradigm, with the lists composed of words. The effect of the inclusion in the list of a high associate of the earlier test item was examined and compared to the effect of repetition. Associative interference was observed, but not in all conditions. Direction of association was a significant factor. The results were interpreted in terms of a model of word recognition proposed by Morton.
