In several experiments, observers were given glimpses of 4-word arrays. Accuracy of word location was tested after each array. Some words, called familiar, appeared many times across the series of arrays; others, called novel, appeared only once. The ratio of novel to familiar words in an array ranged from 0:4 to 4:0. When familiar and novel words were not intermixed (in 0:4 to 4:0 arrays), localization accuracy was higher for ...
