Abstract:

Unwanted autobiographical memories often generate maladaptive affective and behavioural patterns sustained by heightened autonomic arousal and limited cognitive regulatory capacity. Existing interventions rely heavily on effortful top-down strategies, creating a need for methods that activate automatic regulatory mechanisms. Neuro-Rhythmic Non-Predictive Somatic Intervention (NRNPSI) was developed to disrupt stored emotional responses through spontaneous, unpredictable sensorimotor engagement and memory reconsolidation processes that separate emotional charge from factual content. A repeated-measures pretest–posttest design was used with 101 Indian adults experiencing distress related to unwanted memories. Participants completed the Positive and Negative Affect Schedule (PANAS) at baseline, immediately after NRNPSI, and again at a four-month follow-up. The intervention consisted of six progressively complex movement conditions incorporating bilateral coordination, rhythmic unpredictability, vocalisation, and vestibular activation while maintaining gentle awareness of a selected distressing memory. Data were analysed using repeated-measures ANOVA with trend analyses and Bonferroni-corrected pairwise comparisons. Positive Affect (PA) increased significantly from baseline to post-intervention and remained higher at follow-up, whereas Negative Affect (NA) decreased sharply post-intervention but partially rebounded at follow-up, with differences from baseline approaching non-significance. Trend analyses indicated strong linear and quadratic patterns for both PA and NA, reflecting immediate improvement and partial long-term stabilisation. Findings suggest that NRNPSI facilitates automatic emotion regulation by engaging bottom-up mechanisms involved in interoception, sensorimotor disruption, and memory reconsolidation. The intervention produced sustained increases in positive affect and substantial short-term reductions in negative affect, highlighting its potential as an accessible, low-effort alternative to cognitively demanding approaches.
