We recently presented at the Cognitive Development Society in Portland, OR! Check out our posters below:

Our lab manager, Raychel Gordon presented a poster on her work on using gesture to solve mathematical tasks. You can check out her poster here!

Our postdoc, Nadia Chernyak, presented posters on her work bridging numeracy skills and early moral cognition/sharing behavior. You can check out her posters here and here!


We have pre-prints available of the following papers (under review or revision). Please email us ( if you’d like a copy:

    • This study investigated why younger children are less prone than older children are to sharing fairly. In the first study, children were give stickers and told they could share some of them with another individual that didn’t have any. They were then assessed on their numerical cognition (counting skills). We found that their counting skills, not their age, predicted their tendency to share resources equally (give everyone half). That is – children who were better counters – were also better sharers and were more fair towards others. In a second study, we investigated whether numerical cognition would similarly predict children’s understanding of the social norm of fairness. We found that it does not – children generally became more aware of the norm as they got older, but not as they gained counting skills. These results suggest that learning norms is related to getting older, but being able to act on those norms is related to acquiring counting skills.

    • This study asked children to share some toys between two puppets. They were then assessed on their numerical cognition (number knowledge). As children got older, they became better at sharing toys fairly. But, this shift between sharing unfairly to sharing fairly was not explained not by age alone, but by their developing number knowledge. These results suggest that as children gain cognitive skills such as numerical cognition, they become more capable of solving social problems such as sharing fairly.
