“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.”

We are greatly looking forward CDS in Montreal next week!! Come see us at our talks and posters!
LAST CLASS of 2025/2026 academic year is in the books! I know what I'll be dancing to tonight!!
Loved working on this paper with Kat (lead) and Hyo!
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.

Always a pleasure :)
So very happy for you and so very proud of you!!!!
Are you attending @cogdevsoc.bsky.social 2026? Come join us for an afternoon pre-conference workshop on motivation in development! We'll bring together developmental, educational, and computational perspectives to ask: Can we build a unified account of motivation across the lifespan? ✨

New paper out in Child Development (@srcdorg.bsky.social) with Dave Sobel (@candmlab.bsky.social)! ✨ We investigated how 5- to 7-year-old children decide to take on easy versus hard tasks while pursuing a goal. doi.org/10.1093/chid...
I was so excited when I saw your name on the list! will you be at CDS?
Childhood and AI Lab welcome page
The first generation to grow up with AI deserves healthy social relationships. I'm pleased to be a part of this international, interdisciplinary Research Fellowship childhoodandailab.org/our-fellows-... with the #ChildhoodAndAILab from #AIChildSafety.org.
Big news on #SaferInternetDay: I’ve been elected as a Research Fellow with the AIChildSafety.org Childhood & AI Lab.
Grateful to John Zoltner and the Lab for creating space for this kind of work.

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.

💥New paper alert! Dyadic Decisions About Effort: How Caregivers Shape Young Children’s Persistence (with @reutshachnai.bsky.social)
One of my favorites! If you’re curious about what we’ve been up to in @leonardlearnlab.bsky.social, take a look!

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.
This paper about inferences that kids draw on the basis of parental incarceration is now published! Pretty version here: psycnet.apa.org/record/2026-.... Link to full text & summary in thread below.

Is it wrong that I'm trying to use AI to try to come up with AI proof assignments for my students? (pls say no, or better yet, give me some suggestions!).
Are you a US-based PhD student WITHOUT summer funding who is interested in adolescent development, trans youth, and/or gender? Reach out to me about applying to join my lab in Summer 2026 for the VIPS program! psych.princeton.edu/diversity/vi...

Hi #canadian researchers - please sign this petition to help ensure funding isn’t cut to tri council agencies (NSERC, SSHRC, and CIHR). We’re looking at potential 15% cuts to ALL federal spending including grants win.newmode.net/canadianasso...
congratulations!!!

📣📣📣 Hi Everyone! I'm accepting PhD students for the Fall 2026 cycle! Our lab topics include the developmental origins and elaboration of moral cognition/prosocial behavior, persistence, and optimism. More info below!!

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.
