Preregistration is hard, and worthwhile
Preregistration clarifies the distinction between planned and unplanned research by reducing unnoticed flexibility. This improves credibility of findings and calibration of uncertainty. However, making decisions before conducting analyses requires practice. During report writing, respecting both what was planned and what actually happened requires good judgment and humility in making claims.journalMultivariate analysis of psychological dat
To which world regions does the valenceâdominance model of social perception apply?
Abstract: Over the past 10 years, Oosterhof and Todorovâs valenceâdominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorovâs methodology across 11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorovâs original analysis strategy, the valenceâdominance model generalized across regions. When we used an alternative methodology to allow for correlated dimensions, we observed much less generalization. Collectively, these results suggest that, while the valenceâdominance model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed when we use different extraction methods and correlate and rotate the dimension reduction solution.
