Erdelyi argues persuasively for his unified theory of repression. Beyond this, what can studying repression bring to our understanding of other aspects of emotional function? Here we consider ways in which work on repression might inform the study of, on one hand, emotional memory, and on the other, the emotional numbing seen in patients with chronic persistent depersonalization symptoms.

Erdelyi's two key tenets – that repression may be conscious (“suppression”) and that it is context-sensitive – resonate well with findings on unipolar depression. Drawing from this field, I argue that (1) “oppression,” namely, pressure from significant others to refrain from attending to certain mental contents, influences individuals' repression/suppression; and that, (2) individuals actively create the very contexts that facilitate their repression/suppression.

From the perspective of modern dream research, Freud's hypotheses regarding repression and dreaming are difficult to evaluate. Several studies indicate that it is possible to study these topics empirically, but it needs a lot more empirical evidence, at least in the area of dream research, before arriving at a unified theory of repression.

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.

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.

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.

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.

Repression has remained controversial for nearly a century on account of the lack of well-controlled evidence validating it. Here we argue that the conceptual and methodological tools now exist for a rigorous scientific examination of repression, and that a nascent cognitive neuroscience of repression is emerging. We review progress in this area and highlight important questions for this field to address.

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.
