Expectations ------------ *Describe the outcomes you expect/suspect/guesstimate for this study and explain why. Estimate the effect sizes you expect to find, for both the mean reaction time difference and the ex-Gaussian fitted RTV.* Our group has never published an ego depletion study before, but we have just completed data collection for a preregistered ego depletion study. Without any knowledge of the results of the study yet, it is difficult to state what our prior belief is, but, given the small sample sizes of many already published ego depletion studies and the possibility of a publication bias against null results, we tend to think that the actual effect size for the ego depletion effect is likely to be smaller than the average effect size reported in the Hagger et al. meta-analysis. This particular study (Sripada et al., 2014), however, focus on some dependent measures that may be more sensitive than just mean RTs (i.e., RT variability); moreover, unlike some other commonly used depletion (Task 1) tasks such as the video viewing task (which leaves a lot of room for what subjects actually do during the video viewing), the depletion task in this study uses a computerized procedure that leaves less room for variability in terms of what subjects are likely to do during Task 1 performance. Thus, we would not be surprised if this particular protocol might lead to larger effect size estimates than other non-computerized protocols more commonly reported in the literature. If we have to put a specific number for possible effect size estimates, we would say d = .05 to .10 for the mean RTs and .15 to .20 for the ex-Gaussian fitted RT variability.
