We examined the extent to which college students' self-reported study strategy use relates to perceived peer strategy use, allowing us to determine whether college students misperceive peers' use of different study strategies. College students (n = 195) reported their use and perceived peer use of 10 different study strategies. Study strategy use positively related to GPA. Moreover, students perceived higher rates of peers' use of relatively ineffective strategies (e.g., highlighting/underlining) and perceived lower rates of peers' use of the highly effective strategy of distributing practice, compared to actual reports. Perceiving that peers are more likely to utilize ineffective strategies and less likely to utilize effective strategies may contribute to continued use of counterproductive or ineffective study behavior.
