Abstract Details

2005, Master of Arts, Miami University, Psychology.
Four experiments required participants to keep track of the locations of (i.e., spatially update) 4, 6, 8, 10, or 15 target objects. Across all conditions, updating was unaffected by memory set size. Although traditional set size effects were observed (i.e., a linear increase of latency with memory load), these effects were independent of the updating process. The patterns of data and the participant strategies observed in this study were inconsistent with the traditional view of spatial updating as an online, automatic process. The current results are also inconsistent with an online, non-automatic updating process requiring working memory (WM) resources. Instead, it is concluded that participants formed enduring, but somewhat coarse, long-term memory (LTM) representations of the layouts at learning that were used to reconstruct spatial information about the layouts as needed. The current experiments support Amorim, Glasauer, Corpinot, and Berthoz's (1997) two-system model of spatial updating that includes updating through post-hoc reconstruction of spatial information from LTM.
