Quizplus · Accepted Answer

To determine causation between eating a diet high in protein and increased cognitive abilities in children, an experimental study is the most appropriate research method. This would involve randomly assigning children to either a high protein diet or a control diet and then measuring their cognitive abilities over time. This would allow for strict control of variables and the ability to draw cause-effect conclusions.
