A bias in favor of the positive response to high-frequency words in recognition memory

Abstract:
A relatively liberal response bias for high-frequency words and a violation of the mirror effect for hit and false-alarm rates were found in a yes-no recognition-memory test. Subjects more frequently responded "old" to high-frequency words than to low-frequency words. Four experiments were conducted to determine the causes of the different response biases and of the violation of the mirror effect. The word-frequency effect on hit rates did not appear, whereas the false-alarm rate for low-frequency words was lower than that for high-frequency words. When low- or high-frequency words were presented separately in distinct halves of a recognition-memory test, the relatively liberal response bias for high-frequency words was diminished. A model for recognition judgment is proposed that assumes the use of a common criterion for low- and high-frequency words.
