Although it is possible that improved reading speed may be due to operations that are not under executive control, it appears that reading and word identification fluency makes an important contribution to explicit memory judgments (e.g., Johnston et al., 1985; Masson, 1984). The lack of executive control over certain perceptual and cognitive operations does not preclude the possibility that the impact of these operations on processing fluency will be noticed. One function of executive processes is to account for such changes in fluency. A reasonable explanation for the apparent ease of reading a sentence is to attribute the fluency to the beneficial effects of a previous encounter, and this attribution may contribute to a positive decision on a recognition memory test. It is likely that closer examination of this phenomenon will provide important insight into how we become aware of the existence of our memory for reading episodes and other kinds of events.
