The feuding factions of the memory wars, that is, those concerned with the validity of recovered memories versus those concerned with false memories, are unified by Erdelyi's theory of repression. Evidence shows suppression, inhibition, and retrieval blocking can have profound yet reversible effects on a memory's accessibility, and deserve as prominent a role in the recovered memory debate as evidence of false memories. Erdelyi's theory shows that both inhibitory and elaborative processes cooperate to keep unwanted memories out of consciousness.

Despite the importance of research on repression to the study of social movements, few researchers have focused on developing a refined and powerful conceptualization of repression. To address the difficulties such theoretical inattention produces, three key dimensions of repression are outlined and crossed to produce a repression typology. The merit of this typology for researchers is shown by using the typology to: (1) reorganize major research findings on repression; (2) diagnose theoretical and empirical oversights and missteps in the study of repression; and (3) develop new hypotheses about explanatory factors related to repression and relationships between different forms of repression. Such a typology represents an important step toward creating richer theoretical explanations of repression.

Repression continues to be controversial. One insight crystallized by the commentaries is that there is a serious semantic problem, partly resulting from a long silence in psychology on repression. In this response, narrow views (e.g., that repression needs always be unconscious, must yield total amnesia) are challenged. Broader conceptions of repression, both biological and social, are considered, with a special stress on repression of meanings (denial). Several issues – generilizability, falsifiability, personality factors, the interaction of repression with cognitive channel (e.g., recall vs. dreams), and false-memory as repression – are discussed.

Repression has become an empirical fact that is at once obvious and problematic. Fragmented clinical and laboratory traditions and disputed terminology have resulted in a Babel of misunderstandings in which false distinctions are imposed (e.g., between repression and suppression) and necessary distinctions not drawn (e.g., between the mechanism and the use to which it is put, defense being just one). “Repression” was introduced by Herbart to designate the (nondefensive) inhibition of ideas by other ideas in their struggle for consciousness. Freud adapted repression to the defensive inhibition of “unbearable” mental contents. Substantial experimental literatures on attentional biases, thought avoidance, interference, and intentional forgetting exist, the oldest prototype being the work of Ebbinghaus, who showed that intentional avoidance of memories results in their progressive forgetting over time. It has now become clear, as clinicians had claimed, that the inaccessible materials are often available and emerge indirectly (e.g., procedurally, implicitly). It is also now established that the Ebbinghaus retention function can be partly reversed, with resulting increases of conscious memory over time (hypermnesia). Freud's clinical experience revealed early on that exclusion from consciousness was effected not just by simple repression (inhibition) but also by a variety of distorting techniques, some deployed to degrade latent contents (denial), all eventually subsumed under the rubric of defense mechanisms (“repression in the widest sense”). Freudian and Bartlettian distortions are essentially the same, even in name, except for motive (cognitive vs. emotional), and experimentally induced false memories and other “memory illusions” are laboratory analogs of self-induced distortions. Key Words: avoidance; Bartlett; defense; denial; distortion; Ebbinghaus; false-memories; Freud; inhibition; repression; suppression.

Erdelyi's unified theory of repression offers a significant advance in understanding the disparate findings related to repression. However, the theory de-emphasizes the role of motive in repression, and it is argued here that motive is critical to the understanding of repression as it occurs in the mental life of individuals.

We argue that repression is primarily an unconscious process and that the position of Erdelyi is not coherent with Freud's views on the matter. Repression of ideas is a process that takes place without the knowledge of the subject. In this respect, it is essentially different from suppression, where ideas are acted upon by a conscious will.

A major weakness in Erdelyi's account concerns the claim that repression can become conscious. A relational account of cognition demonstrates that if repression is successful, then the repressive act cannot become known. Additionally, “resistance” further distinguishes “repression” from “suppression.” Rather than blurring the distinction between these processes, it is possible to recognise a series of defences. Suggestions are provided for alternative research avenues.

By conflating Freudian repression with thought suppression and memory reconstruction, Erdelyi defines repression so broadly that the concept loses its meaning. Worse, perhaps, he fails to provide any evidence that repression actually happens, and ignores evidence that it does not.
