“…This general interest stems from the fact that change blindness demonstrates the crucial role of visual attention and visual memory in determining the contents of conscious visual perception (Mack & Rock, 1988;Rensink, 2002; see also Gallace, Auvray, et al, 2006;, for examples in the tactile modality). Two recent studies have addressed whether an analogue of change blindness exists in the auditory domain and have shown that changes in auditory scenes can be missed with remarkable ease when not attended (Eramudugolla et al, 2005;Vitevitch, 2003), a phenomenon that the investigators termed change deafness. Eramudugolla et al (2005) explicitly linked the observed phenomenon to the 500-msec white-noise interval they had introduced between the two auditory scenes.…”

“…also Gallace, Auvray, Tan, & Spence, 2006, for a visuotactile version of the paradigm). The existence of change deafness has also been described: A listener's ability to detect a change in the auditory scene declines systematically as the complexity of the scene increases-specifically, when attention cannot be directed to the changing feature or object in advance (Eramudugolla, Irvine, McAnally, Martin, & Mattingley, 2005; see also Vitevitch, 2003).…”

“…In vision, change blindness, which is where people fail to see major changes in a scene as the result of a distractor, or from coincidence with a blink or a saccade, has been extensively studied [65,72]. A similar phenomenon exists for audition, change deafness [78]. It is thus natural that something analogous should occur for touch, and indeed, it does with distractors which are either tactile or visual [29,30].…”

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well controlled tactile signals in order to conveniently demonstrate four different tactile illusions.

“…Saccadic or flash suppression is quite distinct from a variety of other effects which can be classified under the collective name of change blindness (or change deafness, or even change numbness) whereby a change in a scene is not seen (or heard or felt) if that change occurs during a disruption (Rensink et al, 1997, Vitevitch, 2003, Gallace et al, 2006. In "change x-ness", the conditions are such that massive changes in the stimulation are blocked from reaching the conscious experience as the result of an attentional effect, eliciting considerable surprise once the participants are subsequently made aware of them.…”

Tactile suppression of displacement

Abstract. In vision, the discovery of the phenomenon of saccadic suppression of displacement has made important contributions to the understanding of the stable world problem. Here we report a similar phenomenon in the tactile modality. When scanning a single Braille dot with two fingers of the same hand, participants were asked to decide whether the dot was stationary or whether it was displaced from one location to another. The stimulus was produced by refreshable Braille devices which have dots that can be swiftly raised and recessed. In some conditions the dot was stationary. In others, a displacement was created by monitoring the participant's finger position and by switching the dot activation when it was not touched by either finger. The dot displacement was of either 2.5 mm or 5 mm. We found that in certain cases, displaced dots were felt to be stationary. If the displacement was orthogonal to the finger movements, tactile suppression occurred effectively when it was of 2.5 mm, but when the displacement was of 5 mm, the participants easily detected it. If the displacement was medial-lateral, the suppression effect occurred as well but less often when the apparent movement of the dot opposed the movement of the finger. In such cases, the stimulus appeared sooner than when the brain could predict it from finger movement, supporting a predictive rather than a postdictive differential processing hypothesis. Keywords: tactile suppression effects, stable world problem, suppression of displacement, tactile perceptionIn all sensing modalities, individuals have the ability to experience a continuous and stable world in spite of the fact that stimulation changes constantly. The problem faced by the haptic system in order to provide perceptual stability is analogous to the problem faced by the visual system. In the two cases, the primary sensory input arises from sensitive surfaces that can be displaced motorically with respect to the outside world. As Poincaré pointed out (1897), self-generated movement has the benefit of enlarging the portion of the world that is accessible to the senses, but has the downside that it introduces a fundamental ambiguity: It is easy to construct stimuli that are identical when generated by one's own movements or due to the movement of an external agent. This problem has intrigued many scientists: Descartes, Purkinje, Helmholtz, Von Holtz and Mittelstaedt, Sperry, and others; see (Bays and Husain, 2003) for a brief review. More recently Wertheim (1994) and O'Regan & Noe (2001) discussed the analogy between vision and touch from the viewpoint of perceptual stability. The general idea is that an organism needs to be aware of its own movements to resolve ambiguity and that assumptions must be made about the world, such as rigidity and immobility, to succeed at perceiving a stable world (Wexler et al., 2001). Some authors investigated other aspects of the somatosensory stability problem; one of them is object size perception in static contact with the skin for different body regions (...
