 For instance, upon quantifying their level of anger on a rating scale, subjects subsequently experienced decreases in heart rate and cardiac output.Research also indicates that giving labels to aversive stimuli results in a lower skin conductance response when similar aversive stimuli are presented in the future, implying affect labeling can have long-term effects on autonomic responses.Research has found that engaging in affect labeling results in higher brain activity within the ventrolateral prefrontal cortex (vlPFC), and reduced activity in the amygdala when compared to other tasks involving emotional stimuli.
