Abstract: | Donaldson (1996) argued that remember/know judgments can be conceptualized within a signal detection framework by assuming
that they are based on two criteria situated along a strength-of-memory decision axis. According to this model, items that
exceed a high criterion receive a remember response, whereas items that only exceed a lower criterion receive a know response.
Although a variety of findings have been presented in evidence against this idea, Dunn (2004) recently showed that detection
theory is fully compatible with those findings. We present a variety of new results and new analyses that weigh strongly in
favor of the detection interpretation. We further show that a dual-process account of recognition memory is compatible with
a unidimensional detection model despite the common notion that such a model necessarily assumes a single process. The key
assumption of this model is that individual recognition decisions are based on both recollection and familiarity (not on one
process or the other). |
