Spatial distancing reduces emotional arousal to reactivated memories

Feeling the distance: The relationship between emotion regulation and spatial ability in childhood

Research has shown experimentally that if children are taught to use language to create distance (socially, physically, and temporarily) when they revisit a potentially traumatic experience they reduce the intensity of their emotions. Building on this, this study was carried out to explore whether children with better spatial skills are better at such downregulation because of their very aptitude in understanding the concept of distance. Using data from a general-population birth cohort in the UK, the study examined the bidirectional association between emotional dysregulation and spatial ability among children aged 5 and 7 years. The findings reveal a significant reciprocal relationship even after adjusting for family, contextual, and individual confounders including verbal ability: spatial skills at age 5 years were inversely related to emotional dysregulation at age 7 years, and conversely, greater emotional dysregulation at age 5 years was associated with poorer spatial ability at age 7 years. The two paths were equally strong and there was no evidence of differences between them on the basis of sex. Our results suggest that enhancing spatial abilities could be a potential avenue for supporting emotion regulation in middle childhood.

Emotion regulation during encoding reduces negative and enhances neutral mnemonic discrimination in individuals with depressive symptoms

Individuals with depression exhibit dysfunctional emotion regulation, general episodic memory deficits, and a negativity bias, where negative experiences are better remembered. Recent work suggests that the negativity bias in depression may be driven by enhanced mnemonic discrimination, a memory measure that relies on hippocampal pattern separation - a computation that processes experiences with overlapping features as unique. Previously, we found that individuals with depressive symptoms show enhanced negative and impaired neutral mnemonic discrimination. The current study aimed to investigate emotion regulation as an approach toward modifying memory encoding of negative and neutral events in individuals with depressive symptoms. Here we show that applying psychological distancing (a cognitive reappraisal strategy characterized by taking a third-person perspective toward negative events) during encoding was associated with reduced negative and enhanced neutral mnemonic discrimination during retrieval in individuals with depressive symptoms. These results suggest that applying emotion regulation techniques during encoding may provide an effective approach toward altering dysfunctional memory in those with depressive symptoms. Given that pharmacological treatments often fail to treat depression, emotion regulation provides a powerful and practical approach toward modifying cognitive and emotional processes. Future neuroimaging studies will be important to determine how emotion regulation impacts the neural mechanisms underlying these findings.

Finding positive meaning in memories of negative events adaptively updates memory

Finding positive meaning in past negative memories is associated with enhanced mental health. Yet it remains unclear whether it leads to updates in the memory representation itself. Since memory can be labile after retrieval, this leaves the potential for modification whenever its reactivated. Across four experiments, we show that positively reinterpreting negative memories adaptively updates them, leading to the re-emergence of positivity at future retrieval. Focusing on the positive aspects after negative recall leads to enhanced positive emotion and changes in memory content during recollection one week later, remaining even after two months. Consistent with a reactivation-induced reconsolidation account, memory updating occurs only after a reminder and twenty four hours, but not a one hour delay. Multi-session fMRI showed adaptive updates are reflected in greater hippocampal and ventral striatal pattern dissimilarity across retrievals. This research highlights the mechanisms by which updating of maladaptive memories occurs through a positive emotion-focused strategy.
