The Expression of Ego Depletion

Abstract

Abstract. Is depleted self-control capacity detectable from thin slices of behavior? In four video-conditions (early-depleted; early-non-depleted; late-depleted; late-non-depleted) untrained observers rated target persons’ available self-control capacity in Experiments 1 and 2 (without sound) and in terms of fatigue and negative affect (Experiment 3). Videos were analyzed with Noldus FaceReader software (Experiment 4). Ego depletion could reliably be detected from thin slices of behavior. Nonverbal expressions coinciding with ego depletion are associated with cues signaling momentary levels of self-control capacity, fatigue, and some negative affective states. FaceReader analyses indicated that facial expressions coinciding with ego depletion are subtle and are extractable from facial dynamics rather than expression intensities. Results indicate that self-control depletion might not only have intrapersonal effects, but also interpersonal effects.
