One hundred twenty-nine women with documented histories of sexual victimization in childhood were interviewed and asked about abuse history. Seventeen years following the initial report of the abuse, 80 of the women recalled the victimization. One in 10 women (16% of those who recalled the abuse) reported that at some time in the past they had forgotten about the abuse. Those with a prior period of forgetting--the women with "recovered memories"--were younger at the time of abuse and were less likely to have received support from their mothers than the women who reported that they had always remembered their victimization. The women who had recovered memories and those who had always remembered had the same number of discrepancies when their accounts of the abuse were compared to the reports from the early 1970s.

Recovered memories of abuse in women with documented child sexual victimization histories.
Journal of Traumatic Stress. 1995 Oct;8(4):649-73.

The psychological impact of trauma in both the military and civilian arenas has been documented for well over 100 years [1], but the validity of the traumatic neuroses and their key symptoms have been continuously questioned. This is particularly true for posttraumatic amnesia and therapeutically recovered traumatic memories. Freud’s [2] abandonment of his seduction theory was followed by decades of denial of sexual trauma in the psychoanalytic and broader sociocultural realms [3]. Concomitant negation of posttraumatic symptomatology was noted in regard to the war neuroses, emanating equally from military, medical and social spheres [4]. Thus, Karon and Widener [5] drew attention to professional abandonment of the literature on posttraumatic amnesia in World War II combatants. They considered this to be due to a collective forgetting, comparable to the repression of soldiers, but instead occurring on account of social prejudices. He further noted that the validity of memories was never challenged at the time since there was ample corroborating evidence. Recent research confirms the findings of earlier investigators such as Janet [6], validating posttraumatic amnesia of both civilian and military origin. Van der Hart and Nijenhuis [7] cited clinical studies reporting total amnesia for combat trauma, experiences in Nazi concentration camps, torture and robbery. There is also increasing evidence for the existence of amnesia for child sexual abuse. Thus, Scheflen and Brown [8] concluded from their analysis of 25 empirical studies that such amnesia is a robust finding. Since then, new studies, for example those of Elliott [9], have appeared supporting their conclusion. This paper examines posttraumatic amnesia in World War I (WWI) combatants. The findings are offered as an historical cross-validation of posttraumatic amnesia in all populations, including those subjected to childhood sexual abuse.

It is therefore perfectly plausible that memories of childhood sexual abuse could be buried for years and then recalled, and that motivated forgetting, dissociative amnesia, or some other mechanism could account for some of the allegations in cases that Loftus has testified in. But because of the way in which the entire debate has been framed around the issue of "repression" and "recovery," these nuances have been largely ignored.

You may experience waves of disbelief after each memory you retrieve. Whether as a phase or waves, the disbelief is usually accompanied by massive self-hate and guilt. ‘How can I even think such a thing? I must really be warped,’ you tell yourself.

Despite this documentation for both traumatic amnesia and essentially accurate delayed recall, memory science is often presented as if it supports the view that traumatic amnesia is very unlikely or perhaps impossible and that a great many, perhaps a majority, maybe even all, recovered memories of abuse are false…Yet no research supports such an implication and a great deal of research supports the premise that forgetting sexual abuse is fairly common. and that recovered memories are sometimes essentially true.

Women involved in out-patient treatment for substance abuse were interviewed to examine their recollections of childhood sexual abuse. Overall, 54% of the 105 women reported a history of childhood sexual abuse. Of these, the majority (81 %) remembered all or part of the abuse their whole lives; 19% reported they forgot the abuse for a period of time, and later the memory returned. Women who remembered the abuse their whole lives reported a clearer memory, with a more detailed picture. They also reported greater intensity of feelings at the time the abuse happened.
