Sensory grounding techniques interrupt rumination by forcing
Sensory grounding techniques interrupt rumination by forcing attentional resources toward bottom-up external processing, exploiting the bottleneck that prevents simultaneous internal threat-processing and external sensory engagement.
Why This Is a Principle
Grounds in Attention as Gate to Conscious Perception (attention is capacity-limited) and Attention is a finite cognitive resource that must be (attention must be allocated). The 5-4-3-2-1 technique derives its effectiveness from competing for the same limited resource that rumination uses. This is applied design, not the underlying capacity limit.
