Cognitive Science at Princeton
Along with a group of people from psychology, philosophy, linguistics, neuroscience, computer science, and several other departments, I am currently organizing a Cognitive Science Initative here at Princeton. If you are interested in learning more about this initiative, please email me or visit our website for more information. All members of the Princeton community are welcome, especially undergraduate and graduate students.
The Daily Princetonian recently featured an article on the Cognitive Science Initiative.

My primary research interests lie in the intersection of philosophy and cognitive psychology. I believe that a range of issues in philosophy can be illuminated by psychological considerations, and conversely that empirical psychology can benefit from philosophical understanding.

So far, a lot of my work has focused on generics, which are generalizations like “tigers are striped”, “ducks lay eggs”, and “mosquitoes carry the West Nile virus”. These sentences pose difficulties for traditional formal semantics, but are acquired and processed quickly and easily by young children. My research project in philosophy and psychology seeks to understand the features of our psychology that make this possible, and to explore the consequences of these features for philosophy more generally.

Another main area of research for me concerns the philosophy and psychology of prejudice and stereotyping. Since prejudiced beliefs characteristically involve making generalizations about a group of people, understanding the nature of generic generalizations has the potential to illuminate aspects of social prejudice. Much of my on-going work in this area is conducted in collaboration with Marjorie Rhodes.

I am also interested in the question of why certain academic disciplines, but not others, have large gender gaps. In an on-going project, Andrei Cimpian and I are investigating why this might be so, and what might be done to address these gender gaps. The first of our papers on the topic will be published in early 2015 in Science.

I am currently conducting video interviews with philosophers for the Marc Sanders Foundation. The series, entitled Philosophical Conversations, is available on the Foundation website , and on YouTube.
