Do undergraduate courses in psychology Research Methods (RM) and Statistics (STAT) improve general reasoning skills and scientific "critical abilities"? Psychology students concurrently enrolled in introductory RM and STAT were randomly assigned to one of three conditions: a baseline group was tested at the beginning of the semester; another group was tested after completion of KM and STAT; and a third group completed RM and STAT and also received 3 tutorial sessions that specifically emphasized transfer of the course material to reasoning in a more general context.
