Research has demonstrated that emotion modulates specificity in recollection of personally experienced events and the words individuals use during recollection reflect their psychological states. Here, we investigated the linguistic features of autobiographical memory (AM) of different specificity for different emotional events to address how emotion would modulate the psychological mechanisms underlying AM of different specificity. We analyzed 122 participants’ narratives of AM categorized as specific and general under happy, sad, angry, fearful and neutral cues. The use of three groups (emotional process, cognitive process and thinking style) of words was, respectively, compared between specific and general AM in each emotion condition. In retrieval of sad, angry and fearful events, general relative to specific AM contained more affective process words, notably negative words. General AM featured more cognitive process words than specific AM, regardless of emotion type (except neutral). When recalling happy events, general AM featured more analytic thinking words than specific AM, while in recollection of fearful events, general AM featured fewer such words than specific AM. General relative to specific AM about happy experiences contained more narrative thinking words. These findings suggest that the psychological mechanisms underlying top-down and bottom-up retrieval differ between particular types of emotion engaged in AM.

Schizophrenia features pervasive insight deficits, with many failing to recognize symptoms or the need for treatment, predictors of poorer outcomes. Rather than unitary, insight comprises clinical (awareness of illness and need for care) and cognitive (self-reflectiveness and the ability to question one’s beliefs). This review examines whether mental time travel (MTT) – vivid recollection of past events and construction of detailed future scenarios – may underlie insight deficits in schizophrenia. We synthesize evidence up to May 2025 from meta-analyses, experimental studies, and neuroimaging/neuroanatomical reports on MTT (autobiographical memory specificity, future simulation, temporal horizon) and their associations with clinical and cognitive insight. Individuals with schizophrenia show reduced autobiographical specificity, future simulation vividness, alongside a narrowed temporal horizon. These impairments are linked to diminished self-reflection, narrative coherence, and metacognitive abilities, all of which are essential for accurate illness recognition. Neuroimaging indicates that the networks supporting mental time travel, self-reflection, and insight – particularly the default-mode and ventromedial prefrontal circuits – substantially overlap and are disrupted in schizophrenia, with heterogeneity across illness stage and analytic approach. Moderators such as negative symptoms and trauma appear to intensify the MTT-insight links, while depressive mood may paradoxically enhance illness awareness. Although therapies targeting episodic specificity and metacognitive mastery show promise, longitudinal and interventional evidence remains limited. Associations between MTT impairments and insight are robust but largely correlational, so reverse or bidirectional causality cannot be excluded. We outline priorities for longitudinal, interventional, and trauma-stratified studies – attentive to illness stage and default-mode dynamics – to clarify mechanisms and guide targeted interventions.

Psychotic disorders are known to be associated with elevated dopamine synthesis; yet, nondopamine factors may underlie the manifestation of some psychotic symptoms that are nonresponsive to dopamine-blocking agents. One under-explored nondopamine mechanism is neuroplasticity. We propose an account of the course of psychotic symptoms based on the extensive evidence for dopamine facilitation of Hebbian synaptic plasticity in cortical and subcortical memory systems. The encoding of psychotic experiences in autobiographical memory (AM) is expected to be facilitated in the hyperdopaminergic state associated with acute psychosis. However, once such ‘spurious AM of psychosis’ (SAMP) is encoded, its persistence may become dependent more on synaptic factors than dopamine factors. Under this framework, the involuntary retrieval of residual SAMP is postulated to play a key role in mediating the reactivation of symptoms with similar contents, as often observed in patients during relapse. In contrast, with active new learning of normalizing experiences across diverse real-life contexts, supported by intact dopamine-mediated salience, well-integrated SAMP may undergo ‘extinction’, leading to remission. The key steps to the integration of SAMP across psychotic and nonpsychotic memories may correspond to one’s ‘recovery style’, involving processes similar to the formation of ‘non-believed memory’ in nonclinical populations. The oversuppression of dopamine can compromise such processes. We synthesize this line of evidence into an updated dopamine-gated memory framework where neuroplasticity processes offer a parsimonious account for the recurrence, persistence, and progression of psychotic symptoms. This framework generates testable hypotheses relevant to clinical interventions.

Retrograde amnesia for autobiographical memories is a commonly self-reported cognitive side-effect of electroconvulsive therapy (ECT), but it is unclear to what extent objective performance differs between ECT-exposed and ECT-unexposed patients with depression. We investigated the association between exposure to brief-pulse (1.0 ms) bitemporal or high-dose right unilateral ECT and retrograde amnesia at short- and long-term follow-up, compared with inpatient controls with moderate-to-severe depression without lifetime exposure to ECT and receiving psychotropic pharmacotherapy and other aspects of routine inpatient care. In propensity score analyses, statistically significant reductions in autobiographical memory recall consistency were found in bitemporal and high-dose right unilateral ECT within days of an ECT course and 3 months following final ECT session. The reduction in autobiographical memory consistency was substantially more pronounced in bitemporal ECT. Retrograde amnesia for items recalled before ECT occurs with commonly utilised ECT techniques, and may be a persisting adverse cognitive effect of ECT.

Eating disorders (ED) are severe psychiatric disorders characterized by dysfunctional behaviors related to eating or weight control, with profound impacts on health, quality of life, and the financial burden of affected individuals and society at large. Given that these disorders involve disturbances in self-perception, it is crucial to comprehend the role of self-awareness in their prevalence and maintenance. This literature review presents different self-awareness processes, discussing their functioning across different levels of complexity. By deconstructing this concept, we can gain a better understanding of how each facet of self and personality relates to the symptoms of these disorders. Understanding the absence or impairment of self-awareness in ED holds significant implications for diagnosis, treatment, and overall management. By recognizing and comprehending the characteristics of self-awareness, clinicians can develop tailored interventions and evidence-based treatments for individuals with ED. Furthermore, this narrative review underscores the importance of considering temperament and personality factors in the context of ED, as temperament traits and personality characteristics may interact with self-awareness processes, influencing the development and maintenance of ED. Ultimately, the results highlight the pressing need for further research on the development of effective interventions and support strategies grounded in the aspects of self-awareness mechanisms for individuals affected by these disorders.

Autobiographical memories show a temporal pattern with relatively many events recalled from the recent past (recency) and from adolescence to early adulthood (reminiscence bump), and very few events recalled from the first few years of life (childhood amnesia). The current study examined a temporal pattern for external memory – information stored outside of one's brain. Three survey studies asked participants to choose which age(s) in their life they would most want to keep photos from, supposing they had many photos from every year. Participants chose 1 year of photos in Study 1, which sampled undergraduates (N = 499, median age = 19), and in Study 2, which sampled online participants using stratified age brackets (N = 252, age range 18–82). Participants chose 3 years of photos in Study 3, which sampled online participants over 40 using stratified age brackets (N = 240, age range 40–93). Participants’ choices largely showed preferences for time periods likely to be well remembered (recency and the reminiscence bump). Qualitative coding of participants’ reasons for their choices showed common themes, such as positive emotions, connections to other people and pets, life milestones, personal growth, and school. Results suggest that in the case of photos, external memory served to mostly enhance or enrich internal memory and less often to compensate for internal memory.
