Qualitative directions in egocentric spatial reference frame
2012 12th International Conference on Intelligent Systems Design and Applications (ISDA), 2012In this paper, we have presented a formalism for representation of and reasoning about directions in a qualitative way in an egocentric spatial reference frame. Qualitative direction has been separated from dimensionality of spatial objects and as such, the formalism may be used to represent qualitative direction in a dimension-independent way.

An egocentric frame of reference in implicit motor sequence learning
Psychological Research, 2008We investigated which frame of reference is evoked during implicit motor sequence learning. Participants completed a typical serial reaction time task. In the first experiment, we isolated egocentric and allocentric frames of reference and found that learning was solely in an egocentric reference frame. In a second experiment, we isolated hand-centered

In search of biased egocentric reference frames in neglect
Neuropsychologia, 1998The present study was aimed at assessing, by means of visual as well as proprioceptive-kinaesthetic straight-ahead tasks, the possible causal role of the ipsilesional deviation of the egocentric reference frame in determining neglect syndrome. The hypothesis, originally proposed by Ventre et al.

Effect of egocentric and allocentric reference frames on spatial-numerical associations
Quarterly Journal of Experimental Psychology, 2023From an embodied view of cognition, sensorimotor mechanisms are strongly involved in abstract processing, such as Arabic number meanings. For example, spatial cognition can influence number processing. These spatial-numerical associations (SNAs) have been deeply explored since the seminal SNAs of response code (SNARC) effect (i.e., faster left/right ...

Honey bees store landmarks in an egocentric frame of reference
Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 2002Honey bees are well known to rely on stored landmark information to locate a previously visited site. While various mechanisms underlying insect navigation have been thoroughly explored, little is yet known about the degree of integration of spatial parameters to form higher-level spatial representations. In this paper we explore the basic interactions

Intrinsic frames of reference and egocentric viewpoints in scene recognition
Cognition, 2008Three experiments investigated the roles of intrinsic directions of a scene and observer's viewing direction in recognizing the scene. Participants learned the locations of seven objects along an intrinsic direction that was different from their viewing direction and then recognized spatial arrangements of three or six of these objects from different ...

The effect of age on egocentric and allocentric spatial frames of reference
Cognitive Processing, 2009IntroductionLittle is known about the developmental course of spatialmemory, although this topic would be of clinical andtheoretical relevance. Spatial memory plays a fundamentalrole in everyday human activities, like way-finding, localizingplaces or grasping objects.

The role of vision in egocentric and allocentric spatial frames of reference
Cognitive Processing, 2009IntroductionSpatial frames of reference are necessary to encode and torepresent the position of objects in space. Egocentricframes define spatial information in relation to the body,while allocentric ones use external landmarks (e.g. Paillard1991).

Egocentric and allocentric reference frames for catching a falling object
Experimental Brain Research, 2009When programming movement, one must account for gravitational acceleration. This is particularly important when catching a falling object because the task requires a precise estimate of time-to-contact. Knowledge of gravity's effects is intimately linked to our definition of 'up' and 'down'.

Perception, 2007
In three experiments we examined whether memory for object locations in the peripersonal space in the absence of vision is affected by the correspondence between encoding and test either of the body position or of the reference point. In particular, the study focuses on the distinction between different spatial representations, by using a paradigm in ...
