Background The mechanisms underlying generalized forms of dissociative (‘psychogenic’) amnesia are poorly understood. One theory suggests that memory retrieval is inhibited via prefrontal control. Findings from cognitive neuroscience offer a candidate mechanism for this proposed retrieval inhibition. By applying predictions based on these experimen...
Chapter
The Oxford Handbook of Human Memory covers the science of human memory, its application to clinical disorders, and its broader implications for learning and memory in real-world contexts. Written by field leaders, the handbook integrates behavioral, neural, and computational evidence with current theories of how humans learn and remember. Following...
Article
Objectives/Aims The neurocognitive mechanisms underlying dissociative amnesia are poorly understood. It has been proposed that personal memory retrieval is inhibited via top- down cognitive control mechanisms. We developed a behavioural paradigm to test this hypothesised mechanism in a prospectively-recruited case series. Methods Participants incl...
Article
Individuals with depression typically remember their past in a generalised manner, at the cost of retrieving specific event memories. This may impair engagement with cognitive behavioural therapy (CBT) tasks that use concrete episodic information to challenge maladaptive beliefs, potentially limiting their therapeutic benefit. Study 1 demonstrated...
Article
Objectives/Aims Dissociative amnesia refers to loss of autobiographical memory with a presumed psychological, rather than neurological cause. The neurocognitive mechanisms underlying the memory loss are not fully understood. One theory suggests that prefrontal control mechanisms ‘block’ access to autobiographical memories. A parallel body of experi...

Inhibitory control is a fundamental process that enables suppression of representations or processes that interfere with ongoing cognition and behavior. This chapter reviews the role of such control processes in causing forgetting from long-term memory. We consider several functional contexts that trigger inhibitory control, including the need to s...
Article
Background Cognitive dysfunction is often reported in patients who have experienced acute respiratory distress syndrome (ARDS). Extra Corporeal Membrane Oxygenation (ECMO) therapy is increasingly used to manage ARDS patients in ICU, transforming survival rates. However, few studies have examined cognitive outcomes. Methods We examined self-reporte...

Full-text available
Overgeneral autobiographical memory (OGM) refers to the tendency towards increased general memory and reduced specific memory recall, observed in various psychiatric disorders. Previous studies have suggested that inhibitory processes involved in resolving competition between competing memories may reduce memory specificity via retrieval-induced fo...

Objectives Our aim was to compare neuropsychological and psychiatric outcomes across three encephalitis aetiological groups: Herpes simplex virus (HSV), other infections or autoimmune causes (Other), and encephalitis of unknown cause (Unknown). Methods Patients recruited from NHS hospitals underwent neuropsychological and psychiatric assessment in...
Article
The term ‘autobiographical memory’ refers to the recollec- tion of personal facts, episodes and incidents. It can be affected in various ways in clinical disorders, both neurological and psychological. In this paper, examples of ‘anomalies’ in autobiographical memory are discussed in the context of current explanatory theories. Retrograde amnesia (...
Article
Full-text available
Positivity biases in autobiographical memory and episodic future thinking are considered important in mental wellbeing and are reduced in anxiety and depression. The inhibitory processes underlying retrieval-induced forgetting (RIF) have been proposed to contribute to these biases. This investigation found reduced positivity in past and future thin...
