In the context of educational psychology and according to the theories of 'Learning Curves' and 'Transfer of Learning', which of the following statements best represents the scientific explanation of a Plateau of Learning and Bilateral Transfer?

In educational psychology, a learning plateau indicates a state where the speed of learning stops for some time and the curve becomes horizontal. Its main causes can be fatigue, lack of motivation, or poor teaching methods. On the other hand, under 'transfer of learning', bilateral transfer is the process where training acquired by one limb of the body (e.g., right hand) is automatically transferred to the other symmetrical limb (e.g., left hand).
