Product Information

It is notable that two previous studies examining black and white RHI used somewhat different experimental designs. Tapping movements were applied to the two hands at 1 Hz, which, after a period of ∼10 s, elicited an illusion that the participants were touching their own hand (illusion).

The participants, the experimenter, and the rubber hand all wore identical plastic surgical gloves to make the tactile surfaces of the two hands as similar as possible to each other. The time to onset of the RHI may be understood as the period required for achieving multisensory integration. Together, these findings provide strong support for the hypothesis that the feeling of body ownership is mediated by the detection of correlated multisensory signals and that the premotor cortex and the cerebellum play important roles in this process. Thirty-two right-handed healthy participants (15 females; aged 20-46 years) took part in the psychophysical experiment.Five questions, based on those used by Botvinick and Cohen ( 1998), were designed that required a rating of the strength of agreement or disagreement with five perceptual effects.

This is further illustrated in Figure 5, where we show the parameter estimates for the three experimental conditions for the bilateral premotor cortex, the left intraparietal cortex, and the bilateral cerebellum. Pilot experiments showed that the illusion can easily be elicited using passive movements and, in some participants, spontaneously by just looking at the static fake hand for a while ( Tastevin, 1937; Pavani et al.In the “rubber-hand illusion,” the sight of brushing of a rubber hand at the same time as brushing of the person's own hidden hand is sufficient to produce a feeling of ownership of the fake hand. Craske B, Kenny FT, Keith D (1984) Modifying an underlying component of perceived arm length: adaptation of tactile location induced by spatial discordance. The analysis above compared the activity in the illusion condition with the average activity in the two control conditions.

Thus, the premotor activity probably reflects the detection and integration of congruent tactile, proprioceptive, and visual signals from the hands, rather than the representation of an external object in peripersonal space. The participants felt the illusion during illusion and not during the control conditions (paired one-tailed t tests; t > 6. The posterior bank of the inferior part of the precentral sulcus corresponds to area 6, and the anterior bank to the posterior part of area 44. Their designs are justified by their main goals: the experience of RHI with different RH colors and the effect of different RH colors on the implicit bias, respectively. The rubber hand was placed between the participant's two hands on the table, aligned in parallel with and 15 cm to the left of the participant's own right hand.

The participants then moved their left index finger in a straight line to the felt position of the tip of their right index finger, making a single brisk movement.
