Conclusion Criterion shifting during recognition memory

is as stable as, if not more stable than,

criterion placement (a stable cognitive trait1).

The mean session-to-session correlation

coefficients in Study 1 (r = 0.76) and Study 2

(r = 0.83) are comparable to stable traits in

other domains such as visual working

memory capacity2 (r = 0.76).

Although the within subject stability of

criterion shifting is quite high, there are

massive individual differences in behavior.

Criterion shifting MUST be assessed at an

individual level because group analyses

insufficiently describe individual behaviors

IntroductionStrategic criterion shifting during

recognition memory can greatly improve the

outcomes of memory based decisions.

We assessed the test-retest reliability of

criterion shifting during recognition memory

tests across 10 separate sessions.

Criterion placement, a stable cognitive trait1,

served as a comparison measure to assess

whether criterion shifting should also be

considered a stable trait
