In the Harris experiment, subjects wore laterally displacing prisms that caused sensory and motor errors, leading to a change in motor control processes and representations. In the Tseng et al experiment, subjects adapted to visuomotor rotation which resulted in sensory and motor errors, leading to recalibration of the relationship between visual feedback and motor actions.
In the Harris experiment, subjects wore laterally displacing prisms that shifted their visual field to the side. This caused sensory and motor errors such as misjudging distances and reaching out in the wrong direction. The adaptation that occurred was a change in motor control processes and representations, where the brain learned to compensate for the prism's distortion and correct the errors.
In the Tseng et al experiment, subjects adapted to visuomotor rotation where visual feedback was rotated relative to the actual hand movement. This led to sensory and motor errors such as undershooting or overshooting targets. The nature of the adaptation was a change in motor control processes and representations, specifically the recalibration of the relationship between visual feedback and motor actions.
