How does cognitive information impact skill practice with the opposite limb?
How does cognitive information impact skill practice with the opposite limb?
- It eliminates the need for motor control.
- It reduces the focus on the practiced limb.
- It enhances physical strength immediately.
- It provides instant comprehension and application of the skill. (correct)

Flashcards
Bilateral Transfer
Bilateral Transfer
Skill practice with one limb improves learning and skill acquisition on the opposite limb for the same task.
Motor Control Perspective
Motor Control Perspective
The non-practiced limb uses the same muscle/limb patterns as the practiced limb in performing the same movements.
Cognitive Perspective
Cognitive Perspective
Practicing with one limb provides cognitive information about the skill's goal and execution, which improves performance when practicing with the other limb.

Study Notes
Bilateral Transfer
- Bilateral transfer is the phenomenon where practice with one limb improves the learning of a similar skill with the other limb.
- Transfer can occur between motor skills or tasks.
- Two explanations for bilateral transfer exist.
- One perspective is motor control, where the same motor program is used for both limbs.
- The second is cognitive, where practice on one limb helps the learner understand the skill better, leading to faster acquisition when the skill is performed later with the other limb.
Motor Control Perspective
- The non-practiced limb uses the same motor program as the practiced limb.
- EMG (electromyography) shows sub-threshold electrical activity in the other limb during practice with one limb.
- This demonstrates transfer of motor components to the other limb.
- Neuroimaging studies also show cortical activation related to bilateral transfer and neuroplastic changes.
Cognitive Perspective
- Practice with one limb helps the learner acquire cognitive information about skills and how to perform them.
- The learner can then immediately apply this information when the same skill is performed with the other limb.
- Both physical and mental practice lead to similar degrees of transfer.
- Motor and cognitive components interact to explain bilateral transfer.
