The Cutaneous "Rabbit": A Perceptual Illusion

  title={The Cutaneous "Rabbit": A Perceptual Illusion},
  author={Frank A. Geldard and Carl E. Sherrick},
  pages={178 - 179}
Anomalous localizations of mechanical and electrical cutaneous pulses are produced when widely separated bodily points are successively stimulated with trains of taps. The observer experiences a manifold of discrete "phantom" impressions connecting the points actually touched. The theoretical basis for this perceptual phenomenon is not understood, but some boundary conditions are specified. 

An illusion of auditory saltation similar to the cutaneous "rabbit".

The illusion is functionally related to interstimulus interval, number of clicks per speaker, and regularity of pulsing, and appears similar to Geldard and Sherrick's cutaneous "rabbit" illusion.

A dynamic neural model of localization of brief successive stimuli in saltation

Experimental reports suggest that Somatosensory saltation results from spatiotemporal integration in early processing stages, but the exact neural mechanism is unknown.

Chapter 2 – Anatomical, Neurophysiological and Perceptual Issues of Tactile Perception 2.1 Anatomical and Morphological Characteristics of Tactile Receptors

This chapter begins with the anatomical and physiological characteristics of the touch receptors followed by a comprehensive psychophysical overview of touch sensation and perception.

Imaging human touch

Since the early 20th century researchers have used techniques to visualize the neural organization of the human touch system. Imaging human touch covers research from the earliest known work

Saltation through the blind spot

People reported their observations when Geldard’s visual rabbit was induced by stimulating points around the optic disk, and the illusory point was often localized within the region of the blind spot.

Tactile pattern perception

Because efforts to use the cutaneous sense for conveying speech and visual information have met with only partial auccess, it would be useful to understand better the pattern-sensing capabilities of

“Cutaneous Rabbit” Hops Toward a Light: Unimodal and Cross-Modal Causality on the Skin

The results reflect that the brain interprets successive stimuli on the skin as motion in terms of time and space and the concurrent signals from other modalities provide clues for creating unified representations of this external motion as to the extent that “spatiotemporal” synchronicity among modalities is provided.

Tactile Pattern Perception

This paper is an account of the sensory and perceptual factors known or hypothesized to limit the tactile perception of simple two-dimensional patterns, with special attention to the limited spatial bandwidth of touch.

The tactile continuity illusion.

The present study shows for the first time to the authors' knowledge that an illusion of continuity also occurs with vibrotactile stimulation, and suggests that the continuity illusion is common to multiple sensory modalities and that it reflects a fundamental principle of perception.

The cutaneous-rabbit illusion: What if it is not a Rabbit?

The results show that while with pleasant visual stimuli, the three burst durations affected the CRE valence differently; unpleasant visual stimuli masked this variation; and suggest that CRE could have a calming effect for an arousing visual stimulus and an arousal effect for the least exciting visual stimuli.
