“…Although what purportedly comprises the self includes core beliefs and events from the personal past, few researchers have investigated recollections of moral transgressions from the personal past or how those recollections interact with their conceptions of the self. In part due to the inherent difficulty in systematically investigating autobiographical memories (St. Jacques & De Brigard, 2015), the majority of moral psychology research has employed designs that present moral content in the form of artificial vignettes created in the laboratory (e.g., Chituc, Henne, Sinnott-Armstrong, & De Brigard, 2016;Clifford, Iyengar, Cabeza, & Sinnott-Armstrong, 2015). Comparatively few studies have investigated prototypical, everyday instances of immorality that have been personally experienced (however, see Escobedo & Adolphs, 2010;FeldmanHall et al, 2012;Hofmann et al, 2014;Knutson et al, 2010).…”

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time.

“…The main advantage of this device is that it provides a dynamic flow of pictures taken from the first-person perspective without disrupting ongoing experience by actively taking photographs. A growing number of neuroimaging and behavioral studies have shown that the images taken by this kind of device can be used as individually personalized retrieval cues that are particularly effective in eliciting vivid episodic memories (Chow and Rissman 2017;St Jacques and De Brigard 2015;St Jacques et al 2013).…”

“…The FPCN is thought to support effortful control processes to meet task goals, and may play a role in integrating information from the DAN and DN (Gao and Lin 2012;Spreng et al 2010;Vincent et al 2008). During episodic remembering, this network might support the strategic retrieval, monitoring, and recombination of episodic details to form an integrated and coherent representation of the remembered event (Benoit and Schacter 2015;St Jacques and Cabeza 2012;St Jacques and De Brigard 2015). A previous fMRI study (Dobbins and Wagner 2005) found that retrieving internal source information mainly recruited left FPCN areas, whereas retrieving external source information was associated with right FPCN activity.…”

Differential Contributions of Default and Dorsal Attention Networks to Remembering Thoughts and External Stimuli From Real-Life Events

Episodic memories are typically composed of perceptual information derived from the external environment and representations of internal states (e.g., one's thoughts during prior episodes). To date, however, research has mostly focused on the remembrance of external stimuli, such that little is known about how internal mentation is represented within episodic memory. In the present fMRI study, we examined the neural correlates of these 2 components of episodic memories using a novel method of cuing memories from photographs taken during real-life events. We found that, compared with corresponding semantic memory tasks, memories for internal thoughts and external elements were associated with activity in brain areas supporting episodic recollection. Most importantly, however, the 2 kinds of memories also showed differential activation in large-scale brain networks: the remembrance of external elements was associated with greater activity in the dorsal attention network, whereas memories of internal thoughts mainly recruited default network areas. These findings shed new light on the representation of internal and external aspects of prior experience within episodic memory. The default network may contribute to the reinstatement of thoughts experienced during past events, whereas the dorsal attention network may support the allocation of attention to visuospatial features within episodic memory representations.

“…Evidence from fMRI studies in healthy participants allowed the establishing of a brain network of AM retrieval comprising the MTL, prefrontal cortex (PFC) and posterior cortices [20][21][22] . Despite the proliferation of functional neuroimaging studies of AM over the last 10-15 years, many of the critical issues (e.g., MTL involvement according to the remoteness of memories, lateralization of the AM networks) continue to be debated, leading nevertheless to greater refinement of the theories derived from the lesion research.…”

Episodic autobiographical memory (AM) allows one, through the recollection of sensory-perceptual details, thoughts and feelings, to become aware of an event as belonging to one's own past as well as being able to project into one's future. Because AM provides a sense of self-continuity, contributes to the integrity of the self, and helps predicting future experiences, any deficit of AM may have debilitating consequences for everyday life functioning. Understanding AM failure and the underlying neural mechanisms has the potential to shed light on brain reorganization mechanisms and engagement of compensatory processes. Functional magnetic resonance imaging (fMRI) provides the most promising imaging method to tackle these issues. We reviewed evidence from the few studies that used fMRI to investigate the functionality of the residual tissue, the neural reorganization and compensatory mechanisms in patients with neurological conditions due to impaired medial temporal lobe. Overall, these studies highlight the importance of the left hippocampus, which when atrophied and not functional leads to AM deficits but its residual functionality may support relatively normal AM recollection. When damaged hippocampal tissue is not functional, other brain regions (e.g. , the medial prefrontal cortex) may be involved to compensate impairment, but they appear generally ineffective to support detailed episodic recollection.© 2014 Baishideng Publishing Group Co., Limited.
