Person Perception | Stereotyping & Prejudice | Computational Modeling

Despite the astonishing sophistication of the human mind, we often find ourselves entangled in a web of misjudgments, overgeneralizations, and discriminatory decisions. Our remarkable mental machinery, which works so well so often, also frequently leads us astray in the social world

Our biased judgments of others vary across a vast array of contexts, big and small, from our countries of residence to the rooms we occupy, from our demographic identities shared by millions to the individuals in front of us, and even from the generation we belong to down to the hours of day

My research focuses on the interplay between context and cognition: 1) how contexts shape which information we attend to, 2) the mental processes activated in response to this information, and 3) the judgments which follow. I conduct this research using a diverse toolkit of computational models, behavioral paradigms, and data sources

Piecing Apart

Person Perception

Conventional measures cannot distinguish which sources of information (e.g., race, behavior) influence impressions
Multinomial processing trees are used to measure the unique impacts of multiple information sources in person perception

A Cognitive Atlas of Bias

The largest decomposition of implicit bias data: ~1 billion IAT responses, 6 attitude domains, +16 years, x8 demographics
Multinomial processing trees were used to examine the expression of prejudice in society

Salient Cues Shift

Decision Processes

Noticing race information can bias decisions-making,
like weapon identification
Hierarchical diffusion modeling was used to examine the mechanism by which salient emotion (vs. race) information alters racially biased
weapon identification
