In this study, ROC and z-ROC parameters are applied in word recognition memory, with words classified according to frequency and class. In doing so, unbiased techniques can be used to assess hits and false alarms and to obtain standardized distributions for each experimental condition. Our results confirm the existence of differences in word recognition memory for experimental exposition time, type of words and other pre-experimental effects. These data are consistent with familiarity and

... ection models when words' frequency is used, and with familiarity, recollection and dual-route models when words are organized according to class. Finally, we argue in favour of an interactive processing model (words organized according to frequency) versus a processing model nearer to modularity (words organized according to class).
