An egocentric frame of reference in implicit motor sequence learning

open access: closedPsychological Research, 2008
We 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

Honey bees store landmarks in an egocentric frame of reference

open access: closedJournal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 2002
Honey 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

Egocentric frame of reference: its role in spatial biasafter right hemisphere lesions

open access: closedNeuropsychologia, 1999
The reference shift hypothesis of unilateral neglect holds that spatial bias in left neglect stems from a rightward deviation of patients' egocentric frame of reference (ER). Twenty five unselected right brain-damaged patients participated in a straight-ahead pointing task to assess the position of their ER (Experiment 1).

A fronto-parietal system for computing the egocentric spatial frame of reference in humans

open access: closedExperimental Brain Research, 1999
Spatial orientation is based on coordinates referring to the subject's body. A fundamental principle is the mid-sagittal plane, which divides the body and space into the left and right sides. Its neural bases were investigated by functional magnetic resonance imaging (fMRI).
