Which term describes transfer of skill between limbs?

• A. Bilateral transfer
• B. Positive transfer
• C. Retroactive transfer
• D. Zero transfer

Answer: (A)

Transfer of skill between limbs is described by bilateral transfer, also called cross-education. Practicing a task with one limb can improve performance with the other limb because the brain uses shared neural pathways and motor memory representations. This directly matches the scenario of learning transferring from one limb to the other, making it the best description. Positive transfer is a broader idea about helpful transfer between tasks, not specifically about limbs. Retroactive transfer isn’t the standard term for this effect, and zero transfer would mean no improvement in the unseen limb, which isn’t what bilateral transfer describes.
