The effect that a recently learned swing change has on the ability to perform the original swing is an example of proactive transfer.

Proactive transfer refers to the influence that prior learning has on future performance or learning of a new skill. In the context of the question, when a golfer learns a new swing and that change affects their ability to perform the original swing, it is not an example of proactive transfer, but rather could indicate retroactive transfer. Retroactive transfer occurs when new learning interferes with the performance of a previously learned skill.

Thus, saying the statement is false is accurate. The effect of a swing change on the original swing is demonstrating how new learning can disrupt or alter previous performance rather than the previous learning aiding the new skill acquisition, which is the hallmark of proactive transfer.
