Multiple Choice

Allocentric frame of reference is described as which relationship?

Allocentric frame of reference describes how objects relate to each other in the environment, independent of your own position. In other words, it’s an object-to-object relationship: you describe where one object sits relative to another, not relative to you. For example, saying “the chair is north of the table” expresses the location of one object in relation to another, not relative to where you are standing. This differs from an egocentric frame of reference, which would describe where objects are relative to you (for instance, “the chair is to my left”). The other terms aren’t standard ways to express these spatial relationships in this context, so allocentric is the one that best fits the idea of object-to-object relations.
