(A) Subjects learned (encoding) and recalled (retrieval) unrelated-word-pairs. During the encoding block, subjects saw and heard seven pairs of unrelated words and were instructed to learn the word pairs. During the baseline (ctl) block, subjects were instructed to fixate on a symbol (“+” or “o”) and press a button when the symbol changed. During the retrieval block, subjects saw and heard the first word and were asked to remember the second word. (B) The task consisted of six blocks of alternating encoding (Enc) and retrieval (Ret) separated by a baseline control (Ctl) task.
