Shame And Guilt

Our aim was to study effects of different psychotherapeutic treatment components on event-related emotions and psychological symptoms. In this pilot study, we wanted to evaluate if our audiotaped memory retrieval task (MRT) is able to elicit event-related emotions. Also, we made a first attempt to compare the effects of two standardized mini-interventions based on IRRT and PE on event-related shame and guilt, general distress and affective state.

Hippocampal activity is modulated during episodic memory retrieval. Most consistently, a relative increase in activity during confident retrieval is observed. Dorsolateral prefrontal cortex (DLPFC) is also activated during retrieval, but may be more generally activated during cognitive-control processes. The “default network,” regions activated during rest or internally focused tasks, includes the hippocampus, but not DLPFC. Therefore, DLPFC and the hippocampus should diverge during difficult tasks suppressing the default network. It is unclear, however, whether a difficult episodic memory retrieval task would suppress the default network due to difficulty or activate it due to internally directed attention. We hypothesized that a task requiring episodic retrieval followed by rumination on the retrieved item would increase DLPFC activity, but paradoxically reduce hippocampal activity due to concomitant suppression of the default network. In the present study, blocked and event-related fMRI were used to examine hippocampal activity during episodic memory recollection and postretrieval processing of paired associates. Subjects were asked to make living/nonliving judgments about items visually presented (classify) or items retrieved from memory (recall–classify). Active and passive baselines were used to differentiate task-related activity from default-network activity. During the “recall–classify” task, anterior hippocampal activity was selectively reduced relative to “classify” and baseline tasks, and this activity was inversely correlated with DLPFC. Reaction time was positively correlated with DLPFC activation and default-network/hippocampal suppression. The findings demonstrate that frontal and hippocampal activity are dissociated during difficult episodic retrieval tasks and reveal important considerations for interpreting hippocampal activity associated with successful episodic retrieval.

Previous neuropsychological and neuroimaging results have implicated the prefrontal cortex in memory retrieval, although its precise role is unclear. In the present study, we examined patterns of brain electrical activity during retrieval of episodic and semantic memories. In the episodic retrieval task, participants retrieved autobiographical memories in response to event cues. In the semantic retrieval task, participants generated exemplars in response to category cues. Novel sounds presented intermittently during memory retrieval elicited a series of brain potentials including one identifiable as the P3a potential. Based on prior research linking P3a with novelty detection and with the frontal lobes, we predicted that P3a would be reduced to the extent that novelty detection and memory retrieval interfere with each other. Results during episodic and semantic retrieval tasks were compared to results during a task in which subjects attended to the auditory stimuli. P3a amplitudes were reduced during episodic retrieval, particularly at right lateral frontal scalp locations. A similar but less lateralized pattern of frontal P3a reduction was observed during semantic retrieval. These findings support the notion that the right prefrontal cortex is engaged in the service of memory retrieval, particularly for episodic memories.

Background: There is evidence that psychosocial and spiritual interventions of short duration, such as reminiscence therapy, provide positive impacts on quality of life and emotional and existential well-being in adults receiving palliative care. Aim: To determine (1) the feasibility of integrating ‘LIFEView’, a video-based software with >1600 videos of world destinations, in palliative care settings, and (2) positive, neutral or harmful effects of using ‘LIFEView’ videos. Design: A mixed-methods pre–post intervention pilot study was conducted to collect feasibility and preliminary data on physical and psychological symptoms, physiological indicators, spiritual well-being and aspects of quality of life. Setting/participants: Adult patients on an inpatient palliative care unit or receiving care from a community palliative care consultation team who were capable of providing consent and completing the outcome measures were eligible participants. Results: Overall, 27/41 (66%) participants took part in the study. Feasibility criteria, including participant acceptability, low participant burden, tool completion rate and retention rate, were fulfilled, though challenges were experienced with recruitment. Modest improvements, though non-significant, were shown on preliminary data collected on physical and psychological symptoms using the Edmonton Symptom Assessment System–revised, spiritual well-being assessed by the 12-item Functional Assessment of Chronic Illness Therapy – Spiritual Well-Being scale and physiological measurements. Qualitative analysis revealed five themes: motivations for using ‘LIFEView’, perceptions of the technology, reminiscence, ‘LIFEView’ as an adaptable technology and ongoing or future use. Conclusion: A future adequately powered study to investigate the impacts of ‘LIFEView’ on patient well-being and quality of life appears to be feasible.

AbstractSuccessful episodic memory involves dynamic increases in the coordination of activity across distributed hippocampal networks, including the posterior-medial network (PMN) and the anterior-temporal network (ATN). We tested whether this up-regulation of functional connectivity during memory processing can be enhanced within hippocampal networks by noninvasive stimulation, and whether such task-dependent connectivity enhancement predicts episodic memory improvement. Participants received stimulation targeting either the PMN or an out-of-network control location. We compared the effects of stimulation on fMRI connectivity measured during an autobiographical memory retrieval task versus during rest within the PMN and the ATN. PMN-targeted stimulation significantly increased connectivity during memory retrieval versus rest within the PMN. This effect was not observed in the ATN, or in either network due to control out-of-network stimulation. Task-dependent increases in connectivity due to PMN-targeted stimulation within the medial temporal lobe predicted improved performance of a separate episodic memory test. It is therefore possible to enhance the task-dependent regulation of hippocampal network connectivity that supports memory processing using noninvasive stimulation.
