Freud proposed that unwanted memories can be forgotten by pushing them into the unconscious, a process called repression. The existence of repression has remained controversial for more than a century, in part because of its strong coupling with trauma, and the ethical and practical difficulties of studying such processes in controlled experiments. However, behavioural and neurobiological research on memory and attention shows that people have executive control processes directed at minimizing… 
The Role of Inhibitory Control in Forgetting Unwanted Memories: A Consideration of Three Methods
TLDR
It is argued that the ability to control memory is a special case of a broad class of situations thought to require executive control: response override, a function thought to be accomplished by inhibitory processes that suppress the response, enabling more flexible, context-sensitive control over behavior.
Individual differences in the suppression of unwanted memories: the executive deficit hypothesis.
Successfully controlling intrusive memories is harder when control must be sustained
TLDR
The challenges of controlling retrieval appear to cause a decline in control over time, due to a change in state, such as fatigue, which raises the possibility that characteristics often true of people with psychiatric disorders – such as compromised sleep, and increased demand on control – may contribute to difficulties in suppressing intrusive memories.
Suppressing Unwanted Memories
TLDR
This research supports the existence of an active forgetting process and establishes a neurocognitive model for inquiry into motivated forgetting.
Intentional suppression of unwanted memories grows more difficult as we age.
TLDR
It is demonstrated that the ability to intentionally regulate conscious awareness of unwanted memories through inhibitory control declines with age, highlighting differences in memory control that may be of clinical relevance in the aftermath of unpleasant life events.
Suppressing Unwanted Memories Reduces Their Unintended Influences
TLDR
This work presents a neural account in which, during suppression, retrieval cues elicit hippocampally triggered neocortical activity that briefly reinstates features of the original event, which, in turn, are suppressed by targeted neocorticals and hippocampal inhibition.
What Doesn’t Kill You Makes You Stronger: Psychological Trauma and Its Relationship to Enhanced Memory Control
TLDR
College students reporting a greater history of trauma exhibited more suppression-induced forgetting of both negative and neutral memories than did those in a matched group who had reported experiencing little to no trauma, broadly consistent with the view that moderate adversity can foster resilience later in life.
Sleep’s role in the processing of unwanted memories
TLDR
Sleep does not benefit the forgetting of unwanted memories but, on the contrary, REM sleep might even counteract the voluntary suppression of memories making them more accessible for retrieval.
Suppressing Unwanted Autobiographical Memories Reduces Their Automatic Influences
TLDR
Results showed that suppression attenuated brain-wave activity associated with crime-relevant memory retrieval, which rendered waveforms from innocent and guilty participants indistinguishable, which may reflect the need to monitor response conflict arising between voluntary suppression and automatic recognition processes.

Disrupted retrieval in directed forgetting: a link with posthypnotic amnesia.
TLDR
It was concluded here that retrieval inhibition plays a significant role in nonhypnotic as well as in hypnotic instances of directed forgetting and the usefulness of retrieval inhibition as a mechanism for memory updating was also discussed.
Betrayal Trauma: The Logic of Forgetting Childhood Abuse
TLDR
In recent years a polarized debate, often polemical and vitriolic, has seized the attention of psychotherapists and the lay public about the influence of repressed or dissociated memories of childhood trauma in the etiology of adult psychopathology and distress.
On the status of inhibitory mechanisms in cognition: memory retrieval as a model case.
TLDR
It is argued that inhibitory processes are used to resolve computational problems of selection common to memory retrieval and selective attention and that retrieval is best regarded as conceptually focused selective attention.

In a series of directed-forgetting (DF) experiments it was found that inhibition of a to-be-forgotten (TBF) list could be disrupted by a secondary task and completely abolished by a concurrent memory
Ironic processes of mental control.
A theory of ironic processes of mental control is proposed to account for the intentional and counterintentional effects that result from efforts at self-control of mental states. The theory holds
The Contribution of the Anterior Cingulate Cortex to Executive Processes in Cognition
TLDR
Results using event-related fMRI confirm that the anterior cingulate cortex does show error related activity but that the same region of the brain also shows increased response related activity during correct responses associated with response competition, suggesting a re-conceptualization of the contribution of the ACC to executive processes that support an evaluative role.

Many situations require people to stop or change their current thoughts and actions. We present a theory of the inhibition of thought and action to account for people's performance in such
Changing internal constraints on action: the role of backward inhibition.
TLDR
The authors tested the hypothesis that disengagement during intentional shifts between task sets is accompanied by inhibition of the previous task set ("backward inhibition") and predicted increased response times when shifting to a task set that had to be abandoned recently and, thus, suffers residual inhibition.
