“…There have been several studies (Donaldson, 1971;Hudson, Solomon, & Davis, 1972;Rosner, 1970;Simmons, 1973;Tulving, 1967) which have modified the usual multitrial free recall (MTFR) analysis of alternating presentation (P) and recall (R) periods. All of these studies have demonstrated the influence of R periods to be as great as that of P periods on gross dependent variables such as number of words recalled even though more detailed analyses have indicated differences in some components of total recall.…”
