Infants make nuanced moral character judgments as early as 12-months-old, study finds Research by psychologists at the University of Toronto suggests that we begin to make moral character judgments as early as 12-months-old while also recognizing that individuals can exist along a mora...

“As adults, we think there are good people, bad people, and people who are somewhere in between,” says @jessicas.bsky.social, professor of psychology @artsci.utoronto.ca.

“It seems like infants are thinking the same way.”

This research investigated infants’ ability to make moral character inferences. For a wide range of moral roles, infants could use an agent’s past moral behavior to revise their expectations for future moral behavior.

Stoked to share our new lab pub led by the amazing @normanjzeng.bsky.social ! After watching multi-party agent events, infants expect agents to preserve their moral "role" in a resource distribution task. Indiv. variability predicted by infants' social contact.

Why do otherwise rational people disagree about the same evidence? Our new paper finds that group membership is a deeply rooted influence on how we form beliefs, leading even preschoolers to bias their evidential standards and form inaccurate beliefs.

The emergence of disadvantageous inequity aversion between 2–4 years When and how children begin responding to inequitable resource distributions, particularly those that put them at a disadvantage, remains unclear. Acr…

We propose that 2-year-olds show emerging sensitivity to disadvantageous outcomes, but only 4-year-olds' costly responses to unfairness reflect true disadvantageous inequity aversion.

New lab paper with Dave Sobel @candmlab.bsky.social and led by the remarkable @radovanovic.bsky.social and @jaeminhwang.bsky.social. Infants expect equality not only in resource distributions but also resource collections.

Figure shows the methods used in the paper's experiments. In the left column are the methods for Exp 1 (Collection) and in the right are the methods for Exp 2 (Distribution). In each video, three women sit at a table. One sits in the middle, serving as a collector/distributor, and two sit in the foreground with plates. During familiarization trials, resources were collected from or distributed to their plates with an occluder on the screen hiding the outcomes. During test trials, the same videos were played but with the outcomes shown such that infants either viewed an equal collection/distribution or an unequal collection/distribution.

Out in @cognitionjournal.bsky.social with @jaeminhwang.bsky.social, David Sobel (@candmlab.bsky.social), and @jessicas.bsky.social! Most studies of infants’ fairness expectations focus on resource distribution, but in everyday life, we engage in many different kinds of resource exchanges.

New paper! Here (in Nature Communications) we (Ale Geraci, Luca Surian, Lucia Gabriella Tina, & I; work led/run by Ale) show that 5-day-old newborns selectively attend to two distinct forms of prosocial over antisocial action: approaching versus avoiding and helping versus hindering.
