Measuring Fear: Skin Conductance and Self-reporting
Researchers used two measures to determine levels of fear.
One, skin conductance response, described by MIT as “the phenomenon that the skin momentarily becomes a better conductor of electricity when either external or internal stimuli occur that are physiologically arousing” provided a objective numeric value.
Additionally, participant self-reported their levels of fear on a scale of zero to 100, from “no fear” to “extreme fear.”
The Effect of Affect Labeling
Of the three verbal interventions, the affect labeling group – the group that verbalized their fear – showed the greatest reduction in skin conductance response (SCR), which is an objective measure of emotional arousal. Surprisingly, despite the reduction in physiological response, “affect labeling was not shown to be more effective than the other conditions in reducing reported fear.” In the article, the author states that it may be because individuals don’t expect to feel less fear from labeling a negative emotion.
In the interview with Decoded Science, Kircanski continued, “the different channels of fear responding – physiological responses, behavior, and self-reports – don’t always correlate or respond to exposure at the same rates. Studying the effects of affect labeling over a longer time period would help to examine this possibility.”
Implications of the Study
In our interview, Dr. Kircanski noted that earlier research has demonstrated “that children’s ability to label their emotions is associated with, and can also predict, future social skills.” She goes on to say that, “it would be very interesting to examine whether systematically training children in affect labeling can have beneficial effects on their emotional and social functioning.” Research, she reports, is underway to determine if individuals who have undergone traumatic experiences can be helped by affect labeling.
Maybe all of us would benefit from reflective labeling of our own emotional states. Admitting when we are experiencing fear, discomfort, or sadness might just make us feel better.
