CV

Anna Leshinskaya

Cognitive Scientist

I am an Assistant Professor in the Department of Cognitive Sciences at UC Irvine and Fellow at the Center for Neurobiology of Learning & Memory, as well as an affiliated researcher with the AI Objectives Institute. I earned my PhD in Cognitive Psychology from Harvard University in 2015. I am broadly interested in human cognition, its implementation in the brain, and how it can be emulated in machines. My specific research interests are in learning, semantic memory, and most recently, leveraging insights from cognitive science to measure cognitive and moral alignment between humans and large language models. You can read more about my latest work on my lab website.

Tools as Causers

What Drives Tool- and Hand- Selective Cortex?

An area in lateral temporal cortex (LOTC) responds preferentially to images of real-world tools and hands relative to other objects. What drives this selectivity? By teaching participants about novel objects, we gained an important insight: we found that novel objects that appear to influence/cause other events engage this area more than objects which move in response to events. We argue that a causal schema -- beyond shape or motor association -- is an important driver of the selectivity in LOTC and other parts of the temporal lobe. Read the pre-print.

Relations & Features

The Emergence of Relational Representation

How do you represent that coffee goes with bagels, but also looks like tea? Using newly learned relations among novel stimuli, we find that these kinds of representations are localized in distinct parts of the lateral temporal lobe. What things look like, and what they are associated with, are represented distinctly. This was published in Cerebral Cortex.

Memory Reflects Causal Inference

"Backward Blocking" effects in statistical learning

When we incidentally observe pairs of events, say clouds and rain, we bind them in associative memory, thinking of one when we see the other. However, what we recall as related is not just a matter of whether things appeared together: we are also influenced by whether those conjunctions are unique. Just like in causal reasoning, you wouldn't think clouds and rain were related if you often saw rain without clouds. We found that these considerations also govern what people remember from an incidental learning task. Check out the pre-print.or the Cog Sci paper.
