How do people choose among body-, environment-, landmark-, and layout-based reference frames when learning a new space?

The brain treats reference frames as cues to be weighed, not a menu to pick from

In memory-guided reaching, people integrate body-based and environment-based cues rather than relying on just one [1]. That fits a general picture: a reference frame is simply the anchor you measure locations against — your own body, a room's walls, a prominent landmark, or the overall layout of the space. The studies here suggest these anchors are combined, with their relative influence depending on the situation.

The weighting is not fixed. In a virtual navigation task, when the layout of the environment was visually accessible, landmarks played a larger role; when external anchors were weaker, reference frames relied primarily on self-motion cues and body-based information [2]. In other words, the choice is partly a response to what the space offers: a visible, stable layout pulls spatial coding toward external landmarks, while poor external information pushes it back toward the body.

A visible layout and good landmarks pull coding outward

Landmarks are not all equal. In outdoor wayfinding, certain landmark characteristics improved landmark memory and the quality of the resulting cognitive map [5]. That matters for frame selection because a landmark that is easy to remember and recognize is a more useful anchor, making it more likely to shape how the space is represented.

The layout itself can act as an anchor too. When the overall shape of an environment is visually accessible, it appears to support spatial learning alongside landmarks [2]. A useful comparison: a room with a distinctive shape and a few memorable objects gives the learner strong external scaffolding, whereas a featureless corridor leaves self-motion — how far you walked, which way you turned — as the main signal.

Past experience with consistent or conflicting cues changes later stability

What someone learned earlier affects how firmly a spatial representation holds up later. In a rotating-arena study, grid cell activity — a neural signal tied to spatial position — stayed more stable in darkness when the animal had previously experienced coherent rather than conflicting spatial reference frames [3]. The finding is about neural stability in rodents, so it should not be read as a direct account of human frame choice, but it supports the idea that experience with cue consistency shapes how much the brain leans on one frame versus another.

This adds a temporal dimension to the choice. Frame selection is not only a snapshot decision at the moment of learning; the history of whether body-based and landmark-based cues agreed or disagreed appears to leave a trace that influences later spatial coding [3].

Choosing a frame is also about switching between frames

Selection and switching are related but distinct. Work on verbal and non-verbal spatial descriptions examined how people choose and switch among reference frames, including from a developmental perspective [4]. That study did not involve learning a new environment, so it speaks to the general cognitive process of frame selection rather than to navigation through unfamiliar space specifically.

Taken together, the evidence points to a flexible system: external layout and landmarks dominate when they are informative, body and self-motion cues take over when they are not, and prior experience with cue coherence tunes how stable the resulting representation is [2][3]. The reaching work adds that body and environment cues are integrated in naturalistic tasks rather than kept separate [1]. What remains less clear from these studies is the exact rule by which a learner trades one frame against another in a genuinely new, complex space.
