Allocentric and egocentric updating of spatial memories reviews best online dating sites

Spatial updating is one of the fundamental forms of navigation that occurs automatically and continuously whenever an animal moves (Schmidt, et al., 1992), and it contributes to object and scene recognition by predicting the appearance of objects or scenes from new vantage points so that the animal can recognize them easily as it moves (Simons & Wang, 1998).

Spatial updating also has profound impact on spatial reasoning and spatial imagery.

Physical movements consistent with spatial imaginations can facilitate performance, while inconsistent physical movements can lead to impairment (Presson & Montello, 1994).

The path integration process computes the location of an origin relative to the navigator’s current position and orientation.

Path integration has been studied extensively, especially in insects.

The advanced form of spatial updating keeps track of multiple targets in the environment and estimates their new relationship to the animal as it moves around (instead of just the origin alone).

This line of research focuses on examining the dissociation between the two types of spatial imagery transformations: allocentric spatial transformations, which involve an object-to-object representational system and encode information about the location of one object or its parts with respect to other objects, versus egocentric perspective transformations that involve a self-to-object representational system.

In our lab, we examine individual differences in egocentric (imagining taking a different perspective in space) and allocentric (mentally manipulating objects from a stationary point of view ) spatial abilities, and develop assessments of these abilities .

Our research also seeks to discover the relation of these two types of spatial ability to locomotion and spatial navigation.

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.

Spatial updating refers to the cognitive process that computes the spatial relationship between an animal and its surrounding environment as it moves based on perceptual information about its own movements. Journal of Comparative Physiology A-Sensory Neural & Behavioral Physiology, 181, 13-20.

Vector summation is usually considered to be the underlining mechanism.
