Introduction: This study aimed to predict false memory based on information processing strategies (surface and subsurface) and metacognitive skills with in eighth and ninth grade female students in Isfahan. Method: The population consisted of 25 465 eighth and ninth grade female students of Isfahan public ordinary schools in the 95-96 school year. With cluster Random sampling and Using Morgan table, 378 subjects were selected as the sample. The instrument used to evaluate the false memory was Diss Rudiger McDermott (DRM) paradigm. Pintrich and De Groot (MSLQ) self-regulated learning strategies questionnaire used to measure information processing strategies and O'Neil and Abedi metacognitive state questionnaire (1996) used to measure metacognitive skills. Data were analyzed using stepwise multiple regression analysis. Results: Multivariate linear regression analysis showed that summarizing had positive and significant relationship with false memory whereas comprehension and false memory had negative and significant relationship. The curve linear regression analysis showed that the relationship of metacognitive awareness and the self- monitoring with false recognition is significant in the form of a curve. Conclusion: This results showed that summarizing increases false memory but comprehension decrease it. Also with increase of metacognitive awareness and self-monitoring the false recognition increase in the beginning and then with continuing of increase in these strategies the rate of false recognition start to decrease.
