The Role Of Peripheral Vision In Configural Spatial Knowledge Acquisition, Lisa J. Douglas

This study investigated the importance of the peripheral visual field for acquiring configural spatial knowledge, especially knowledge about structural components like doorways, corners, and walls, but also information about objects. Although peripheral vision helps us orient our bodies in space, navigate successfully through an environment, and physically interact with objects in near physical space (Kesner & Creem-Regehr, 2012; Burgess, Jeffrey, & O’Keefe, 1999), previous research has not investigated the role of the peripheral visual field for the acquisition of spatial knowledge during navigation. All participants in this experiment viewed a virtual navigation tour through a four-room environment with objects located …

Current car navigation systems use maps that show part of a region and are sequentially presented as the driver moves along a route, displaying information that is relevant to immediate guidance, such as the surrounding streets and turn indicators. Rizzardo, Colle, McGregor, and Wylie (2013) have shown that sequentially presented, partial maps populated with landmark objects can also facilitate spatial knowledge acquisition. Spatial knowledge is useful for evaluating GPS instructions and navigating after the fact. However, the optimal number of landmarks on map segments has not been extensively tested. The Object-Based Spatial-Episodic Representations for Visual Environments (OBSERVE) theory indicates that …
Measuring Configural Spatial Knowledge With Alternative Pointing Judgments, Lisa J. Douglas
Measuring Configural Spatial Knowledge With Alternative Pointing Judgments, Lisa J. Douglas

Configural spatial knowledge has been tested by having people point from one object to another or by having them sketch maps from memory. Several different pointing judgments have been used, but these judgments appear to differ both in superficial characteristics and in their implied theoretical mental model of spatial representation. This experiment compares two different pointing judgments: judgments of relative direction, based on a quasi-Euclidean model of spatial representation; and object-based judgments, based on an object reference model of spatial representation. Results supported the object reference model. Object-based judgments were more accurate, were made with more confidence and had shorter …
