According to Das and Naglieri’s theory, intellectual activity is a result of the interdependent functioning of three neurological systems:
1. Arousal/Attention system: This system helps you focus on the task at hand, which is why the first step is C, where you concentrate on the task (e.g., studying for a test).
2. Encoding and understanding: Once attention is activated, you begin to understand and process the information required for the task, which corresponds to B.
3. Planning: After the information is processed, you plan how to achieve the goal, which in this case involves scheduling time and clearing doubts, as in D.
4. Response: Finally, when the test is announced, you act on the planning and understanding you have developed, which is step A.
Thus, the correct order is A, B, C, D.
