Hand Posture Modulates Perceived Tactile Distance

Posture and Tactile Distance 1 RUNNING HEAD: Posture and Tactile Distance Hand Posture Modulates Perceived Tactile Distance

Posture modulates implicit hand maps.

Several forms of somatosensation require that afferent signals be informed by stored representations of body size and shape. Recent results have revealed that position sense relies on a highly distorted body representation. Changes of internal hand posture produce plastic alterations of processing in somatosensory cortex. This study therefore investigated how such postural changes affect implic...

Action sounds recalibrate perceived tactile distance

Experiment 1 Experiment 2 II. Experimental Design ., • self-produced action sounds are represented in the action-recognition system (Aglioti & Pazzaglia, 2010) & influence subsequent actions (Bresin et al., 2010)  Auditory-body relationship revealed by the enhanced audio-tactile integration: • in the space close to the head (Kitagawa & Spence, 2006) • in the peri-hand space, after tool use (Se...

Effects of hand posture, breathing type, arm posture and body posture on hand errors.

This study consisted of 2 experiments. Experiment 1 examined the effects of hand posture, arm posture and body posture on hand error, while experiment 2 examined the effects of hand posture, breathing type and body posture on hand error. This study showed that more hand errors occurred in the nondominant hand, extended arm, normal breathing and standing compared with errors in the dominant hand...

Effects 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...
