| Research Abstract |
Experts differ from novices in their capacity to perceive and chunk (recode) important relationships between task elements. Thus, learning to represent relations is an important part of chunking. Accordingly, this project investigated the interaction between learning and relational memory load. Previous research identified the superior parietal lobule as sensitive to differences in the amount of relational information stored in working memory (Phillips & Niki,2002;2003). In this project, brain imaging experiments revealed that the difference between high versus low relational information in superior parietal lobule is modulated by amount of learning. A greater difference between high versus low relational information was identified for the retention of learned relations than novel relations. These results suggest that the superior parietal lobule is important for establishing relational memories.
