Visuo-tactile links in covert exogenous spatial attention remap across changes in unseen hand posture.
We investigated the effect of unseen hand posture on cross-modal, visuo-tactile links in covert spatial attention. In Experiment 1, a spatially nonpredictive visual cue was presented to the left or right hemifield shortly before a tactile target on either hand. To examine the spatial coordinates of any cross-modal cuing, the unseen hands were either uncrossed or crossed so that the left hand la...
متن کاملEffects of hand posture on preparatory control processes and sensory modulations in tactile-spatial attention.
OBJECTIVE Event-related brain potentials (ERPs) were measured to investigate spatial coordinate systems involved in the control of preparatory tactile-spatial orienting, and in subsequent attentional modulations of somatosensory processing. METHODS On each trial, a visual precue directed attention to the left or right hand, where infrequent tactile targets had to be detected. Hands were posit...
متن کاملTactile-visual links in exogenous spatial attention under different postures: convergent evidence from psychophysics and ERPs.
Tactile-visual links in spatial attention were examined by presenting spatially nonpredictive tactile cues to the left or right hand, shortly prior to visual targets in the left or right hemifield. To examine the spatial coordinates of any crossmodal links, different postures were examined. The hands were either uncrossed, or crossed so that the left hand lay in the right visual field and vice ...
متن کاملVisuo-Spatial Attention in ADHD Children: Investigating the Asymmetry
Objectives: The purpose of the present study was comparing visuo-spatial attention between children with Attention Deficit Hyperactivity Disorder-Inattentive (ADHD-I) type and normal children. Methods: In this cross-sectional study fifteen (7-10 years of age) children were classified with ADHD-I type and 15 normal children were matched for age, sex, and IQ. They were selected trough simple r...
متن کاملWithin-hemifield posture changes affect tactile–visual exogenous spatial cueing without spatial precision, especially in the dark
We investigated the effects of seen and unseen within-hemifield posture changes on crossmodal visual-tactile links in covert spatial attention. In all experiments, a spatially nonpredictive tactile cue was presented to the left or the right hand, with the two hands placed symmetrically across the midline. Shortly after a tactile cue, a visual target appeared at one of two eccentricities within ...
