The aim of the present study was to investigate whether university students can adjust their study strategies to meet the cognitive demands of testing; a metacognitive self-regulatory skill. One hundred and fifty undergraduates attended three lectures as part of a course on the psychology of individual differences. These participants were then assigned randomly to each of two groups. In the first group, the participants were instructed to study for a test that required deep-level cognitive processing. In the second group, the participants were instructed to study for a test that required surface-level cognitive processing. Results of the study showed that university students do adjust their study strategies so that they are in line with the cognitive processing demands of testing. It was also found that study strategies mediated the relationship between the type of test items expected and the test performance. (Contains 3 tables.)
