Tactile suppression and visual attention: Effects on tactile discrimination performance
The aim was to investigate tactile discrimination performance under various active and passive conditions and explore the influence of visual information. Participants had to discriminate the direction of lateral pin strokes on their fingertip under three conditions. In one condition (" static ") only tactile stimulation was provided. In a second condition (" active ") the shear force device wa...
متن کاملActive Movement Reduces the Tactile Discrimination Performance
Self-performed arm movements are known to increase the tactile detection threshold (i.e., decrease of tactile sensitivity) which is part of a phenomenon called tactile suppression. Today, the origin and the effects of tactile suppression are not fully understood. Tactile discrimination tasks have been utilized to quantify the changes in tactile sensitivity due to arm movements and to identify t...
متن کاملAlpha power is influenced by performance errors.
Error commission evokes changes in event-related potentials, autonomic nervous system activity, and behavior, presumably reflecting the operation of a cognitive control network. Here we test the hypothesis that errors lead to increased cortical arousal, measurable as changes in electroencephalogram (EEG) alpha band power. Participants performed a Stroop task while EEG was recorded. Following co...
متن کاملTactile coactivation-induced changes in spatial discrimination performance.
We studied coactivation-based cortical plasticity at a psychophysical level in humans. For induction of plasticity, we used a protocol of simultaneous pairing of tactile stimulation to follow as closely as possible the idea of Hebbian learning. We reported previously that a few hours of tactile coactivation resulted in selective and reversible reorganization of receptive fields and cortical map...
متن کاملIs the Player More Influenced by the Auditory than the Tactile Feedback from the Instrument?
What sensory feedback, tactile or auditory, is the more important for a musician when playing? In an attempt to answer this question, subjects were asked to play along with a metronome while the auditory feedback from their playing was manipulated. The preliminary results showed a tendency for matching sound with sound, i.e. players initiated strokes earlier as the delay increased. Increase in ...
