Studies on multi-target spatial updating have been conducted primarily with humans. A few studies have shown that non-human animals, including insects, are capable of updating more than one target as well (Collett, Collett & Wehner, 1999). Jancke (Eds.), Spatial Processing in Navigation, Imagery, and Perception, pp. It has been shown that animals are more likely to use visual cues (i.e., visual dominance) when other cues (such as the internal senses) are in conflict with them. For example, bees flying through a patterned tunnel with wind can correctly estimate the distance traveled, suggesting that optical flow information overrides the energy expenditure measure (Srinivasan et al., 1996). Thus it has constraints in its ability to provide accurate guidance for long-range navigation. Some studies suggest that path integration is reset every once in a while.

A special case of this test is known as the novel shortcut task.

When an animal moves from one place to another and turns from one direction to another, the spatial relationship between the animal and its environment changes constantly. Time-courses of memory decay in vector-based and landmark-based systems of navigation in desert ants, Cataglyphis fortis.
