Combining Locations From Working Memory And Long-Term Memory Into A Common Spatial Image, Nicholas Giudice, Roberta L. Klatzky, Christopher R. Bennett, Jack M. Loomis

Spatial Information Science and Engineering Faculty Scholarship

This research uses a novel integration paradigm to investigate whether target locations read in from long-term memory (LTM) differ from perceptually encoded inputs in spatial working-memory (SWM) with respect to systematic spatial error and/or noise, and whether SWM can simultaneously encompass both of these sources. Our results provide evidence for a composite representation of space in SWM derived from both perception and LTM, albeit with a loss in spatial precision of locations retrieved from LTM. More generally, the data support the concept of a spatial image in working memory and extend its potential sources to representations retrieved from LTM.


Perception Of 3-D Location Based On Vision, Touch, And Extended Touch, Nicholas Giudice, Roberta L. Klatzky, Christopher R. Bennett, Jack M. Loomis Jan 2013

Perception Of 3-D Location Based On Vision, Touch, And Extended Touch, Nicholas Giudice, Roberta L. Klatzky, Christopher R. Bennett, Jack M. Loomis

Spatial Information Science and Engineering Faculty Scholarship

Perception of the near environment gives rise to spatial images in working memory that continue to represent the spatial layout even after cessation of sensory input. As the observer moves, these spatial images are continuously updated. This research is concerned with (1) whether spatial images of targets are formed when they are sensed using extended touch (i.e., using a probe to extend the reach of the arm) and (2) the accuracy with which such targets are perceived. In Experiment 1, participants perceived the 3-D locations of individual targets from a fixed origin and were then tested with an updating task …
