“…Although Young (1926), Stalnaker and Riddle (1932), True (1949), and Reiff and Scheerer (1959) reported dramatic increases in recall of childhood events for hypnotically age-regressed subjects, serious methodological weaknesses have been documented (Barber, 1962; O'Connell et al, 1970). Indeed, investigators who have carefully used conditions in which the experimenters do not know the hypotheses and proper motivational control groups have found no evidence for increased accuracy of recall of childhood events uniquely attributable to hypnotic-age-regression procedures (Barber, 1961; Best & Michaels, 1954; Mesel & Ledford, 1959; O'Connell et al, 1970).…”
