Familiarity and recollection refer to memory processes that are engaged during recognition judgments. A task that is widely used to operationalize these processes is the remember-know task. In this thesis, it was aimed to examine the effect of different decision criteria on the corresponding “remember” and “know” responses with respect to the signal detection model of recognition memory. In line with this purpose, a standard recognition memory task was applied with a between-subjects criterion manipulation. A conservative response bias was induced by presenting participants a test list, in which only 30% of the items were previously studied. Conversely, a liberal response bias was induced by presenting participants a test, in which only 70% of the items were previously studied. The results from two experiments showed that the base rate manipulation led to a shift in response criterion, which was calculated based on the assumptions of the signal detection theory. Moreover, “know” and “remember” responses were associated with responses made with lower and higher confidence, as well as responses that were associated with lower and higher response thresholds, respectively. Hence, the obtained results are in line with the assumptions of the single process models of recognition memory based on the finding that the two processes can be represented on a mutual medium (i.e. memory strength). However, the lack of an effect in terms of the corresponding hit and false alarm rates for “remember” and “know” responses require further research in order to distinguish or associate the two processes.
