We study human memory and spontaneous thought.
What makes an experience sticky -- likely to form a lasting memory or shape our spontaneous thoughts?
Are there laws that govern how we move from one thought to the next?
How is our ability to re-experience the past implemented in the brain?
How can we use stories as a tool to learn about the architecture of the human mind?
Our goal is to contribute to understanding how the human mind works, particularly in the domains of memory and spontaneous thought.
We strive to pursue a rigorous and creative science, that addresses cognition at the level of subjective experience and its underlying computation.
We believe that promoting diversity in those who do science (e.g., race, gender, class, sexuality, ability) is a necessary step towards achieving the rigorous and creative science of the mind that we want.
stories change how we think
Stories seem to have a lasting influence on how we think. How do we measure this influence? What are its consequences? Our lab examines how and why stories linger in our spontaneous thoughts, using techniques from natural language processing. [talk] [paper]
prior knowledge and new learning
If we know a lot about something, will our memory for a specific instance of seeing that thing be richer in detail? Here, we use naturalistic stimuli (e.g., famous faces, popular logos) to explore how prior knowledge affects the quality of our memories. [paper]
hippocampus and memory
The hippocampus, a brain structure tucked deep in our medial temporal lobe, is involved in our ability to remember past events. Are all parts of the hippocampus equal? Here, we examine the possibility that different aspects of the hippocampus (anterior vs. posterior) preferentially represent gist-like vs detailed information. [paper]
default mode network
The default mode network, a set of functionally coupled brain regions, plays an important role in a variety of contexts, including: remembering, future imagining, story comprehension, mentalizing, and mind-wandering, among others. Could these regions be ideally situated in the brain to represent our internal models of the external environment? [paper] [commentary]

demo: free association
Interested in measuring spontaneous thought? Check out our code for a free association task that we use in some of our research. [demo]
demo: self paced reading
In some of our experiments, we have participants read stories. Check out our self paced reading task and read a story at different levels of coherence.
We're slowly building a repository of tutorials for the various tools we use in the lab (e.g., word embeddings in R; permutation testing; etc).
cool things (from the internet)
A way to use AI tools to estimate the distribution of gender and ethnicities in the authors we cite. Check out this online tool to help you generate your own.
A searchable (!) repository of openly available behavioural datasets.
Interactive fiction, where you collaborate with transformer models to create a story world of your own.
Word2Vec embedding space, but like, space. Fun and interactive way to get a handle on word embeddings.
An exhaustingly large, if not exhaustive, list of common tropes in TV and movies.
