Project Overview
- Status:
COMPLETE - 37 participating labs collected data in 18 countries on 5 continents
- 1018 babies tested
- 94 authors on Developmental Science publication
In this project we investigate a fundamental aspect of human nature: evaluating others’ actions as praiseworthy or blameworthy. We do so in a closely coordinated, multi-laboratory, standardized study aimed at replicating the helping/hindering finding reported by Hamlin, Wynn, & Bloom, 2007. Using a video-taped version of the original puppet show, labs from around the world collected data from infants between the ages of 5.5 and 10.5 months.
