Task duration and task order do not matter: no effect on self-control performance

Abstract: The strength model of self-control proposes that all acts of self-control are energized by one global limited resource that becomes temporarily depleted by a primary self-control task, leading to impaired self-control performance in secondary self-control tasks. However, failed replications have cast doubt on the existence of this so-called ego depletion effect. Here, we investigated between-task (i.e. variation in self-control tasks) and within-task variation (i.e. task duration) as possible explanations for … Show more

“…However, in contrast to previous ego-depletion research, this reduction in self-control availability had no effect on the performance of the subsequent pressurized muscular endurance task, which also required self-control. Although this finding is inconsistent with earlier research (Bray et al, 2008), research has shown that performance and the perception of cognitive fatigue have repeatedly failed to correlate (Wolff, Sieber, Bieleke, & Englert, 2019). This may be owing to cognitively orientated activities being more multifaceted than physical fatigue, and therefore, they are more difficult to specify (Burke et al, 2018).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Our results replicated earlier studies showing that more self-control demanding and longer versions of the primary task induce higher levels of self-control investments and costs (Wolff et al, 2019). This affected neither the perceived depletion nor the performance in the secondary task, except higher error rates among participants who had worked longer on the transcription task at the beginning of the Stroop task and for incongruent stimuli.…”
