Step-by-step explanation:
Melanie's capacity to understand that she can both experience anxiety and envision herself winning the art competition represents her development of self-awareness and the ability to hold multiple perspectives. This cognitive ability is known as metacognition.
Metacognition involves reflecting on one's own thoughts, feelings, and behaviors. In Melanie's case, she is aware of her anxiety and is also able to imagine herself succeeding. This demonstrates her growth in understanding her own emotions and thoughts related to the competition.
Metacognition is an important skill to develop as it helps individuals monitor and regulate their own learning and emotions, and it can lead to improved performance and resilience in various aspects of life.
