Final answer:
The statement is (B) false; the effectiveness of an external focus of attention in therapy does not depend on its proximity to the patient. External focus relates to paying attention to the effects of actions on the environment, rather than body movements. This concept does not intersect with how nearsighted or farsighted vision operates.
Step-by-step explanation:
The statement “External focus of attention is more effective if placed closer to the patient” seems to be mixing concepts from ophthalmology and psychological or physical therapy. In the ophthalmic context, a nearsighted person indeed has a point of focus between the lens and the retina, meaning they have trouble seeing objects far away without corrective lenses. Contrastingly, a farsighted person has a point of focus behind the retina, so they see distant objects more clearly than close ones.
In terms of therapy or physical rehabilitation, an external focus of attention means focusing on the effects of one's actions on the environment rather than on one's own body movements. The effectiveness of an external focus of attention during physical performance or therapy is not necessarily related to proximity but rather to the relevance and clarity of the instructions or feedback.
Therefore, the answer to the question is B. False. The effectiveness of an external focus of attention is not determined by physical proximity to the patient.
