Electrodermal signatures of stress during tactical law enforcement training

= .031, d = 0.86), with shorter post-training latency in Controls and stable latency in Experimental. Findings indicate that officer recruit tactical performance can be predicted from electrodermal dynamics measured during scenario-based training, and that performance improvement can be predicted from stress regulation dynamics. Finally, a brief biofeedback-based breathing intervention significantly slowed down the threat-triggered sympathetic arousal. The results support the use of biofeedback-based stress interventions in recruit training to shape autonomic responses and improve tactical performance.
