The Study of Remembering the Knowledge on a Subject Area

This article presents research on extracting knowledge on a subject from the semantic memory. The individual strategies of knowledge retrieval and their relationship to the effectiveness of remembering were analyzed. The selection of strategies was based on a preference for semantic or episodic «keys» during information recollection. On the first stage of the study participants listened to a lecture on the artificially created subject. It was followed by two stages of delayed retrieval of the lecture contents (4 and 15 months later). Then using the categorical fields the reconstruction of the retrieval course was performed and retrieval effectiveness and the subjective reports of participants on the process of remembering were analyzed. We show that the preference of a strategy cannot be considered as an indication of its greater efficiency. In order to effectively extract knowledge on a subject from semantic memory it is necessary to address the semantic «keys». Episodic «keys» are more effective in their own memory subsystem.
