Amy studies how social and economic factors shape the way we see, think and feel about, and make decisions for others. She was born and raised in rural Minnesota and received a B.S. in Psychology from the University of Wisconsin - Madison, where she investigated intersectionality and discriminatory judgments with Professor Colleen F. Moore. Next she moved to New York City and researched intertemporal choice and risky decision making at Columbia University with Professors Elke U. Weber, Eric J. Johnson, and Bernd Figner at the Center for the Decision Sciences. She then completed a PhD at New York University with Professor David Amodio, where she examined economic scarcity effects on discrimination through multiple levels of social perception - from mental representations to neural encoding. She most recently worked as a post-doc with Professor Mina Cikara at Harvard University investigating social value and reinforcement learning. Amy joined the Cornell psychology department as an Assistant Professor in July, 2016, and is excited to get back to the woods.

Mikaela Spruill   email


Mikaela is a second year graduate student who studies perceptual bias at the intersection of race and gender. Her research focuses on revealing the ideological barriers to social justice that exist for minority groups. She works to understand how our beliefs about the overarching American system amplify discrimination and inequality in order to uncover interventions that can aid in reducing bias and addressing disparities in America. Mikaela earned her MA in experimental psychology from Wake Forest University, and her BS in neuroscience from The College of William and Mary. She enjoys going to concerts, doing yoga, and watching football.

Christopher Monteiro             email


Christopher’s research focuses on the relationships between ideology and low-level cognitive mechanisms, such as memory and perception. His current work focuses on the relationship between the age of ideas and perceptions of their veracity, and on the relationship between ideology and social perception. Christopher earned his BA in psychology and MA in conflict resolution at the University of Massachusetts, Boston. He is interested in the effects of changes in the economy and political ideology on memory and beliefs regarding scientific information and also in carnism, the ideology that supports using non-human animals for food, and it’s relationship with prejudice toward human social groups.

Steve Strycharz           email


Steve studies how perceived time scarcity (i.e., feeling as if one does not have enough time to do the things that need to be done) influences life satisfaction as well as everyday judgments and decisions. One project explores how life satisfaction is differentially influenced by subjective busyness (i.e., perceived time scarcity) and objective busyness (i.e., number of hours spent on work-related activities). Before beginning his Ph.D. at Cornell, Steve studied psychology at the University of Michigan, working primarily with Ethan Kross.  When not in the lab, Steve enjoys spending time in the natural areas around Ithaca – hiking, running, biking, and kayaking. He also enjoys traveling, cooking, and watching his favorite team– Liverpool FC.
