Preregistered replication (Wagenmakers et al., 2016) that investigated the facial feedback hypothesis (Strack, Martin, & Stepper, 1988).
A data frame with three variables:
Authors of original study (see Wagenmakers et. al, 2016)
Measure of effect size: Cohen's d (difference between smile vs. pout condition)
Measure of precision: standard error of Cohen's d
The facial-feedback hypothesis states that people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences (Strack, Martin, & Stepper, 1988).
