sensorimotor interactions with the environment, such as target-directed movements or navigation?It is well-established that neurons in many brain regions, especially parieto-frontal cortex, represent the spatial location of objects in egocentric spatial reference frames, centered on various body parts such as the eye (retina), the head, or the hand (Colby, 1998; Hagler et al., 2007; Sereno and Huang, 2014).The restriction will be removed automatically once this activity stops. The use and neural representation of egocentric spatial reference frames is well-documented.However, whether the brain also represents spatial locations of external objects relative to other objects in an allocentric or object-centered spatial reference frame, or constructs an abstract map of such relationships that is independent of the egocentric perspective, is debated (Bennett, 1996; Driver and Pouget, 2000; Wang and Spelke, 2002; Burgess, 2006; Wehner et al., 2006; Rorden et al., 2012; Li et al., 2014).Correspondence concerning this article should be addressed to Jesse Sargent, who is now at the Department of Psychology, Washington University in St. Evidence was sought on the possibility that whereas certain environmental aspects may be updated independently of one another, other aspects may be grouped (or chunked) together and updated as a unit. In order to gain insight into the nature of human spatial representations, the current study examined how those representations are affected by blind rotation.
In this paper, these models are reviewed on theoretical rather than empirical grounds and are shown to be similar.
On the basis of perceptual experience with the immediate environment, humans and other animals construct internal representations of the landmarks, boundaries, and objects that make up that environment.
Evidence of these persisting internal representations is provided by the ability to locate objects and landmarks in the absence of ongoing perceptual support (e.g., Kosslyn, Ball, & Reiser, 1978; Mc Namara, 1986) and by neurophysiological data (e.g., Burgess & O’Keefe, 1996; Cressant, Muller, & Poucet, 1997; Ekstrom et al., 2003).
For instance, the ability to work on a complicated mathematical problem utilizes one's working memory.
One highly influential theory of WM is the Baddeley and Hitch multi-component model of working memory.
