A Multilab Replication of the Ego Depletion Effect

There is an active debate regarding whether the ego depletion effect is real. A recent preregistered experiment with the Stroop task as the depleting task and the antisaccade task as the outcome task found a medium-level effect size. In the current research, we conducted a preregistered multilab replication of that experiment. Data from 12 labs across the globe (N = 1,775) revealed a small and significant ego depletion effect, d = 0.10. After excluding participants who might have responded randomly during the outcome task, the effect size increased to d = 0.16. By adding an informative, unbiased data point to the literature, our findings contribute to clarifying the existence, size, and generality of ego depletion

Indirect Assessment of Implicit Disgust Sensitivity

We propose a single-block, single-target, Implicit Association Test (SB-ST-IAT) for measuring implicit disgust sensitivity. Based on dual process theories, we tested the construct validity of this new measure using a sample of N = 75 participants. Incremental validity of the newly developed SB-ST-IAT was demonstrated using a disgust sensitivity questionnaire as a direct measure of disgust sensitivity, as well as two behavioral criteria. A controlled approach versus avoidance task with disgusting stimuli (worms) was employed as a measure of controlled behavior. Facial disgust expression and withdrawal of hands and upper body from the disgust stimuli were used as indicators of automatic behavior. Implications of our research for the validation of indirect measures are discussed

tDCS executive function

By means of transcranial direct current stimulation applied to the left dorsolateral prefrontal cortex we investigated the causal role of this brain region for two facets of executive functions, namely working memory and interference control. In a between-subject design, we contrasted anodal and cathodal stimulation with a sham condition without stimulation and tested effects on performance in a Stroop task under stimulation as well as in an n-back test 15 minutes after stimulation ended
