Zusammenfassung

We investigated the effects of experimental manipulations of attention and motivation upon tactile discrimination learning. Attention and motivation have a prominent role in cognitive learning processes and in motor learning – here manipulations by dopaminergic stimulation or by top-down mechanisms can influence learning. In tactile perceptual learning, discrimination ability is strengthened by repeated exposure to sensory stimuli, which is often accompanied by an enlargement of the representation of the trained finger in primary sensory cortex. Since attention is not an indispensable prerequisite for learning,…
