I’m teaching a summer course and I want to have a mock-conference day where we watch short conference-style talks for one part of the class and do a mock poster session for another! Does anyone have suggestions (&links) for recent cog-dev talks available online I can share with my students?? 👀

New paper in @nathumbehav.nature.com with @simonag.bsky.social and Darko Odic! We show that young children and adults use different internal signals for reporting memory versus perceptual confidence judgements. But by age six, the internal signals become comparable. Free access link: rdcu.be/fgZvV

Domain generality is an emergent, not inherent, property of metacognition
Nature Human Behaviour - Adults show a shared bias in confidence across memory and perception, but sensitivity and efficiency differ by domain. Children under six struggle to compare confidence...

Come see the Lucca/ Benitez labs present at CDS! I’ll be presenting results of a registered report project investigating 5-8 year olds’ and adults’ inferences about learning and teaching with difficult tasks (poster session 4)

New paper with Ben Morris and Alex Shaw out last week in @cognitionjournal.bsky.social! We find that children are sensitive to who has better evidence when evaluating how people behave in disagreements. www.sciencedirect.com/science/arti... 1/3

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...

Children's decision to challenge themselves on a novel task relates to their metacognitive monitoring of their ability
Abstract. We examined potential processes by which children decide to make hard as opposed to easy choices to accomplish a goal. Five- to 7-year olds (N =

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.
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.

Last week I gave my 1st conference talk at #SRCD2025 in a symposium @elisemahaffey.bsky.social and I co-chaired together “The effort equation: Towards an integrative understanding of the factors that drive children’s adaptive persistence” with speakers @elainewang.bsky.social and Alexis Burke!
