Abstract
Spatial working memory, the cognitive process of storing and manipulating information about locations of objects in the world, is not yet fully understood. The weighting of multiple sensory cues into spatial working memory is a crucial, everyday function. Here, we study the interaction between spatial working memory and spatial coding sensory cue integration by using a video projection table with motion tracking to study participants' behavior while playing a 2D firefly capture game, in which the location of a landmark relative to the target is perturbed prior to participant response. We hypothesized that participants would show greater error with increased distance, and that participants would rely on a stable landmark more than a landmark that moves. Both of our hypotheses were supported; in the context of spatial working memory, allocentric cues are weighted according to both: distance from target, stability, and the interaction of both factors. These findings help clarify the everyday mechanisms of spatial cognition.
