Cognitive science is, nominally, the science of thinking. We argue that the field has no theory of what thinking is and, even worse, that the topic has largely dropped out of focus. 1/

Abstract of the paper

Figure 1 - experimental setup

Figure 2 - accuracy over time

Figure 3 - semantic similarity within/across games

I always thought preschoolers were too egocentric to do well on communication tasks where they had to talk about novel referents. Old papers reported they'd say stuff like "this one looks like my uncle's hat."

Hadza food-sharing is egalitarian, yet offers in giving games have never matched the equitable redistribution seen in real life.

In this study, we allowed people to give *or* take. Lifelike equitable distributions only appeared when people took from peers in surplus.

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.

Part 1: How do LLMs work? YouTube video by Andrew Perfors

I just created a series of seven deep-dive videos about AI, which I've posted to youtube and now here. 😊

Targeted to laypeople, they explore how LLMs work, what they can do, and what impacts they have on learning, well-being, disinformation, the workplace, the economy, and the environment.

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.

Animacy semantic network supports causal inferences about illness Making causal inferences about illness, compared to making causal inferences about mechanical breakdown and reading causally unconnected sentences, activates a semantic brain network implicated in the conceptual representation of animate entities (e.g. people, animals).

New paper with Marina Bedny out in eLife (elifesciences.org/articles/101...). Main takeaway: Different kinds of causal knowledge are supported by different semantic brain networks - consistent with the "intuitive theories" framework from developmental psychology. 1/
