True or False:<br> Repetition Practice interferes with the ability to learn new information
ankoles [38]

Repetition Practice interferes with the ability to learn new information is true.

Repetition helps kids learn faster, builds confidence, and fortifies the neural connections in their brains that support learning. Practice doesn't always make perfect while learning a new skill. Zachariah Reagh and Michael Yassa, neurobiologists at UC Irvine, discovered that while repetition improves the factual content of memories, it can decrease the amount of detail associated with such memories.
