Özet

The purpose of this study was to indicate the changes in the implicit and explicit memory under awake and sleep conditions by using a battery that can measure different subsections of memory. 24 healthy individuals participated in this study. Modified versions of the Auditory Verbal Learning Test and the Modified Word Stem Completion Test were applied to the study and control groups within the scope of Modified Multiple Block Design (MMBD). While the control group did not listen to any words during sleep, the study group listened to the list of selected words. The originality of this research is the generated meaningless words given during sleep by using Mongolian language. While asking the words taught before sleep, both groups had a similar rate for remembering after sleep. The study group that was given the words during sleep had relatively higher scores for correct completions than the control group that was not given any words during sleep. The difference in correct completions of meaningless words in the Mongolian language was found to be statistically significant in the evaluation of the implicit memory. Also, there was a significant difference between the study and control groups for the implicit memory. There is a positive effect on implicit memory processes during sleep. Thus, learning can occur during sleep. Moreover, the generated MMBD enabled evaluation of both the implicit and explicit memory and also MMBD can also be useful for various consciousness states.
