Final answer:
John is utilizing metacognition, which involves awareness and regulation of one's own cognitive processes to enhance learning and recall.
Step-by-step explanation:
John's behavior exemplifies metacognition, a cognitive process involving awareness and understanding of one's own thought processes. His recognition that he performs better when studying in the early afternoon and when reviewing material by rephrasing it demonstrates a heightened level of self-awareness and strategic learning. Metacognition involves the ability to plan, monitor, and evaluate one's own cognitive processes, leading to more effective learning and memory retention.
By actively engaging in metacognitive activities such as planning study sessions, reviewing material, and explaining concepts in his own words, John is likely to enhance his understanding and recall of the information. Metacognition not only facilitates better academic performance but also empowers individuals to become more independent and efficient learners by optimizing their cognitive strategies based on self-awareness and reflection.
