====Modified modified free recall====
J.M. Barnes and B.J. Underwood (1959) expanded Briggs's (1954) study by implementing a similar procedure. The main difference in this study, however, was that, unlike Briggs's (1954) "modified free recall"  (MFR) task where participants gave one-item responses, Barnes and Underwood asked participants to give both List 1 and List 2 responses to each cued recall task. Participants' ability to recall both items was termed the "modified modified free recall" (MMFR) technique. Equivocally to Briggs's (1954) results, RI occurred when C<sub> I </sub> recalled responses gradually came to exceed B<sub> I </sub> responses. Barnes and Underwood argued that because there was "unlimited recall time" to produce multiple-item responses, the fact that A<sub> I </sub>-C<sub> I </sub> responses still trumped A<sub> I </sub>-B<sub> I </sub> responses represented an account of unlearning.<ref name = barns>{{cite journal | last1 = Barnes | first1 = J.
