Flyer summarizing CDS Symposium: Title: Children’s developing understanding of the rights and responsibilities of collective decision-making Time: Saturday, April 11th, 2:30-4:00PM (Symposium S3.2 in Montreal 4) Talk 1: Children’s emerging understanding of emotional effort and its implications for representation in collective decision-making (Mia Radovanovic & Samuel Ronfard) Talk 2: Who should be the leader? Children’s democratic preferences when selecting a leader (Isabel Alessandra Herrera Guevara, Lana Isabel Abad, & Nadia Chernyak) Talk 3: Deciding together or alone?: Children’s expectations of leaders’ decision-making behaviors (Nicole H. Park & Isobel A. Heck) Talk 4: Holding leaders accountable: Examining 3-8-year-old children’s evaluation of leadership failure (Jessica J. Lee & Andrew Scott Baron)

Come check out our symposium on Saturday at #CDS2026! I'm biased but I think we have a really cool set of talks thinking about power as something that is negotiated dynamically and bidirectionally, and I'll be presenting new work done with @samuelronfard.bsky.social 🙌

Schedule of research presentations from the Lehigh Little Learners Lab at CDS 2026 in Montreal!

Can't wait for #CDS2026! My lab is excited to share some of our ongoing work featuring collaborations with Madison Pesowski's KIDS Lab at UFV! I hope you'll stop by and chat :)

Origins of understanding fair resource collection Concerns about fair resource exchanges are pervasive across development. However, existing work has focused primarily on resource distributions. The p…

Overall, these results suggest that infants hold broader expectations for fairness that transcend a particular type of resource exchange, with interesting possibilities for future work on equity, fairness, and age-related change! Read the full article here: www.sciencedirect.com/science/arti...

A two-panel scatterplot showing infants’ looking times (in seconds) as a function of age (14–18 months) for two experiments. Experiment 1: Collection (left panel) and Experiment 2: Distribution (right panel). Each panel contains green dots representing fair trials and purple dots representing unfair trials. Trend lines with shaded confidence bands are plotted for each trial type. Critically, the Collection panel shows an Age x Trial Type interaction such that infants looked longer to the Unfair Collection relative to the Fair Collection as they got older. On the other hand, there is no evidence of an interaction in the Distribution panel, instead, infants look longer on average to Unfair Distribution relative to Fair Distribution across the ages tested.

However, we also found evidence of age-related changes! Fairness expectations emerged later for resource collection events than for resource distribution events.

Here, we focus on "taxation." North American 14-17-month-olds were shown an actor who collected resources either equally or unequally. We find that infants looked longer to unequal resource exchanges, both when resources were unfairly taken from or unfairly given.

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 announcement! journals.lww.com/greenjournal...

The Journal of Obstetrics and Gynecology is an unusual place for me to publish… Let me tell you the story of this paper.

New open access paper with @drmack.bsky.social! 🎉 The menstrual cycle has non-linear effects on pattern separation as measured by the mnemonic similarity task (MST). Perceived stress facilitates pattern separation performance independent of the menstrual cycle.

Apparently the scheduler has been tricky for people to work with. We had a date wrong below and now just got access to rooms. Please see updated schedule of CoCoDev presentations from/with our lab here!

#SRCD2025 come check out the Toronto Early Cognition Lab (@jessicas.bsky.social)! @elainewang.bsky.social will also be presenting work with @julia-a-leonard.bsky.social that we got to collaborate on :)

Come check out the EAST & DoT Labs at #SRCD. 🤩 I'm excited to share our work on children's causal reasoning about historical structural barriers, as well as their pragmatic inferences from what others seek--and do not seek--to explain!

From input to action: Examining how subtle contextual cues sustain gender inequalities in childhood Friday, May 2nd, 11:30-1:00PM (Room 200A) When seeking an explanation is an explanation: Children’s ability group stereotypes are influenced by explanation-seeking Jamie Amemiya, Serena Spada, Molly Tallberg, & Lin Bian The role of family inequality on children’s normative understanding of household labor Kiana Gee, Allegra J. Midgette, & Nadia Chernyak Gender inequities in expectations for invisible labor begin in childhood and persist into adulthood Mia Radovanovic, Tim Wei-Ting Chao, Nila Curtosi, Sofia Westerhoff, Emma Soler, & Jessica A. Sommerville The role of gender stereotypes in shaping communality in children Cameron Hall, Katharina Block, Antonya M. Gonzalez, Andrei Cimpian, Toni Schmader, & Andrew Scott Baron

Come to our symposium w/ @jamieamemiya.bsky.social, Kiana Gee, & Cameron Hall at #SRCD2025. We'll talk about how children may acquire, internalize, and perpetuate gender stereotypes. I'm really excited for this one, I think the talks build on each other well to unravel different mechanisms!

The Early Child Cognition Research Group at ASU (PIs: Kelsey Lucca and Viridiana Benitez) will be presenting our work at #SRCD2025! Hope to see you there!

I’m not saying AI is evil — god forbid I be that moralistic and clear — I’m saying it is worse than that. It’s MID. Too mid to do much more than externalize some risk, produce some mid documents, and accelerate climate risk as a cute little benefit.

People-pleasing linked to gender differences in problem-solving: Study A new study found that, on average, girls excel at replicating the teacher’s instructions in the classroom — even when those instructions are wrong.

Research led by Psychology PhD candidate @radovanovic.bsky.social & Prof. @jessicas.bsky.social is investigating how people-pleasing socialization influences how children solve problems.

Children consider others’ need and reputation in costly sharing decisions - Scientific Reports Scientific Reports - Children consider others’ need and reputation in costly sharing decisions

New paper!

Children’s sharing is influenced by factors like others' need and reputation, but research has typically examined these factors in isolation. This study explores how different combinations of need and reputation affect costly sharing decisions.

For decades, developmental psychologists have noticed that optimism declines with age. Why does this presumably good thing decrease across development? In this Nature Reviews Psych article, @jessicas.bsky.social and I draw from prior hypotheses to offer an integrated account.

Looking for to seeing folks in Glasgow for ICIS!!! Here are our lab presentations!

we've launched our newest citizen-science game, Tone Guesser, led by postdoc and webdev whiz @courtneybhilton.bsky.social

it's both fun and hard (!) and tests your intuitions about tones in music and colour.
