Members of Reasoning Lab and allied labs in 2023. The UCLA Reasoning Lab, directed by Professors Patricia Cheng and Keith Holyoak of the Department of Psychology, is dedicated to theoretical and empirical investigation of thinking and reasoning. Together with many collaborators and students, the lab combines behavioral studies of human cognition with computational and neuropsychological projects. The lab focuses on thinking in normal human adults, but is also guided by work on cognitive development and animal cognition. The lab is currently supported by grants from the National Science Foundation and Google. Here you will find information about the research of the lab and publications it has produced, with links to full-text pdf files for some of our most important findings. Our group collaborates closely with the Computational Vision and Learning lab directed by Professor Hongjing Lu, and code for computational models and other resources can be found here.
