Research interest

My laboratory focuses on a variety of topics in cognitive psychology. During the last few years, my students and I have been focusing on some of the following questions: How do people learn to classify objects? How do they learn functions? Can the reluctance of some people to accept psychology as a science be related to the process of categorization? Why do some artificial stimuli with a high degree of human likeness appear to be eerie? Does a source’s credibility influence people’s ability to evaluate the validity of a syllogism?
