A Multiple Resource Examination of Time Sharing Performance for Egocentric and Allocentric Frames of Reference
Perception and Performance
DescriptionEgocentric and allocentric frames of reference (FoR) are important for navigation aids, but each has benefits and drawbacks. Incorporating both FoR could be beneficial for offsetting the drawbacks of each viewpoint, but research on the ability of these FoR to be timeshared is lacking. The current study investigated whether FoR ought to be regarded as separate pools of cognitive resources under the framework of the Multiple Resource Model (MRM). In a dual task paradigm, results indicated that performance improved when both tasks used the same frame of reference. Such findings imply frames of reference are not separate pools in a multiple resources sense. Improved performance may be a result of task similarity, which can improve performance according to the shared processing routines hypothesis. Implications are discussed, including for navigation aid design.
