Our lab draws on the methods used across a number of disciplines (psychology, philosophy, linguistics, neuroscience, computer science) to answer central questions about how the human mind works. A primary topic we focus on is how humans represent and reason about non-actual possibilities—the vast infinity of things that didn’t (or have not yet) happened. Our understanding of what is possible is central to many of our most impressive, and uniquely human capacities: causal reasoning, theory of mind, planning, linguistic communication, moral judgment, and so on. Our work focuses on these aspects of high-level cognition, both separately, and jointly by developing an understanding of the way that they all draw on a common underlying capacity to think about what is merely possible.
A main line of research has been to demonstrate the role that value plays in constraining which possibilities humans default to considering. Partly this work has just been an effort to uncover the empirical phenomenon: We’ve found that when adults are forced to decide what things are possibility when answering quickly (thus relying a default understanding of possibility), they begin to treat immoral actions as impossible. Moreover, children early in development judge immoral and imprudent actions to be impossible, even on reflection. The other part of this work has been to make sense of this phenomenon theoretically and formally. We’ve recently argued that value plays a similar role in which possible actions are considered in first-person decision making, and that this similarity is not merely a coincidence. We’ve also tried to provide a philosophically-oriented overview of how the resulting psychological picture of how we represent possibilities fits with theoretical work on judgments that require us to represent alternative possibilities.
A paradigm example of the kind of cognition that depend on representations of alternative possibilities is our judgments about what caused what. If you’re trying to figure out what the cause of a forest fire was, for example, part of what we do is consider what would have happened if things had happened differently: What if the person hadn’t made a campfire when there was a fire warning? Or what if there hadn’t been a drought? What is particularly interesting is that people share a strong tendency to consider certain kinds of counterfactuals and not others. We don’t tend to consider counterfactual possibilities in which there was no oxygen in the air and so the forest fire didn’t occur. Our work has investigated the way that that our ideas about what is normal shape our causal judgments because people tend to focus on counterfactuals that are more normal, ones in which people do the right thing, likely events occur, and things function normally.
Another example of cognition involving alternative possibilities is how we judge whether someone was forced to do something and whether they were responsible for what they did. Typically, we only judge that someone was forced to do something when we don’t think it was possible for them to do something else instead. And we typically don’t hold other people response for their actions when they had no better alternative. Our work has demonstrated that judgments of force and responsibility depend on default representations of possibility, and that these judgments are surprisingly influenced by our moral judgments because we tend to not treat immoral alternative actions as possible. In fact, the impact of morality can lead to paradoxical patterns of judgments, where we judge that a person S was forced to do some action a by another person P, but that P did not force S to a.
Research on theory of mind has primarily focused on demonstrating and understanding the ability to represent others’ non-factive mental states, e.g., others’ beliefs in the false belief task. Our work has instead focused on how people represent others’ factive mental states, like what others know. We have developed a simple and theoretically motivated account on which tracking another agent’s understanding of the world and keeping that representation separate from one’s own are the essential features of a capacity for theory of mind. In ongoing work, we’ve review the theory of mind literature from across the cognitive sciences (research from comparative cognition, developmental psychology, cognitive psychology, linguistics, experimental philosophy, etc.) and find that across almost every measure, factive representations, like what others know are more basic than non-factive representations like what others believe.
In our work on language, our lab largely focuses on developing formal semantic theories of modal terms—words like ‘might’ or ‘could’. Specifically, we’ve tried to provide an account of the meaning of these terms that integrates our emerging understanding of how people represent non-actual possibilities at a psychological level with standard semantics accounts that have been developed over the past half century in linguistics and philosophy. In pursuing this work, we have often tested the unique predictions of these formal models in experimental studies that form part of the growing tradition of work on experimental semantics. For a few examples, see our work on knowledge-wh, force, and epsitemic modals.

Read MoreWe are always looking for folks who join us in interdisciplinary cognitive science research!
If you are interested in working with us as a PhD student or postdoc, please send me an email. State briefly why you are interested and attach a CV, including information about the research you’ve been engaged in recently. No need for a separate cover letter or certificates. Important: please insert “PhD Application” or “Postdoc Application” in the subject line. If you are applying to a specific advertisement, note this in your email.
If you are alerady graduate student in PBS or CS at Dartmouth and would be interested in pursuing work collaboratively with our lab, email me (or any group member) or just stop by my office (Moore 256)
If you are interested in pursuing a research in cognitive science at Dartmouth, you're in good company! Undergraduate researchers typically commit to working roughly 10 hrs per week, and we have a strong preference for students to plan to work in the lab for more than one consecutive term, since this will allow you to contribute substantively to projects and perhaps even develop your own research ideas. If you are interested in joining the lab as a Research Assistant, please fill out this form and let us know more about your background and interests. We will reach out shortly.
