Spatial reference frame of incidentally learned attention.
Visual attention prioritizes information presented at particular spatial locations. These locations can be defined in reference frames centered on the environment or on the viewer. This study investigates whether incidentally learned attention uses a viewer-centered or environment-centered reference frame. Participants conducted visual search on a monitor laid flat on a tabletop. During trainin...
متن کاملReasoning about directions in an egocentric spatial reference frame
Within qualitative spatial reasoning, spatial objects having directions have been abstracted in different ways; directed line segments, oriented points etc. have been used. In certain applications, it becomes necessary to reason about directions of objects without focusing on the dimensionality of these objects. We present a framework for representation of and reasoning about directions in a qu...
متن کاملAn Empirical Investigation into Spatial Reference Frame Taxonomy using Dialogue
Reference frames are abstract representations that enable people to describe the location of objects using projective descriptions such as, above, below, left, and right. There have typically been three broad classes of reference frames identified in the literature: Those that are based upon the environment, those based upon an object and those that are egocentric. However, the exact details of...
متن کاملCultural background shapes spatial reference frame proclivity
Spatial navigation is an essential human skill that is influenced by several factors. The present study investigates how gender, age, and cultural background account for differences in reference frame proclivity and performance in a virtual navigation task. Using an online navigation study, we recorded reaction times, error rates (confusion of turning axis), and reference frame proclivity (egoc...
متن کاملAn Optimal Alternative Theorem and Applications to Mathematical Programming
Given a closed convex cone P with nonempty interior in a locally convex vector space, and a set A ⊂ Y , we provide various equivalences to the implication A ∩ (−int P ) = ∅ =⇒ co(A) ∩ (−int P ) = ∅, among them, to the pointedness of cone(A + int P ). This allows us to establish an optimal alternative theorem, suitable for vector optimization problems. In addition, we characterize the two-dimens...
