“…The majority of implicit memory studies employing the word stem completion task, however, have found memory performance dissociations where, due to neurological damage, benzodiapine use or depression, explicit memory is impaired yet im-plicit memory remains intact (e.g., Danion et al, 1991;Zimmerman, Willard-Schroeder, Grange, & Singer, 1989;Fang, Hinrichs, & Ghoneim, 1987;Graf & Schacter, 1985;Schacter & Graf, 1986;Watkins, Mathews, Williamson, & Fuller, 1992; but see Elliot & Greene, 1992). These studies suggest that word completion is a successful measure of implicit memory since such dissociations are a hallmark of the explicit/implicit memory distinction and are taken to indicate that they are distinct and separable forms of memory (Richardson-Klavehn & Bjork, 1988).…”
