Three‐month‐olds show a negativity bias in their social evaluations
Open accessAbstract
Previous research has shown that 6‐month‐olds evaluate others on the basis of their social behaviors – they are attracted to prosocial individuals, and avoid antisocial individuals ( Hamlin, Wynn & Bloom, 2007 ). The current studies investigate these capacities prior to 6 months of age. Results from two experiments indicate that even 3‐month‐old infants evaluate others based on their social behavior towards third parties, and that negative social information is developmentally privileged.

“Due to the theorized adaptive value of biasing negative social information (Cacioppo, Gardner & Berntson, 1997; Vaish et al., 2008), it would be telling to find evidence for a negativity bias in very young infants.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
