Final answer:
Don has a higher aptitude in mathematical intelligence compared to practical intelligence. This is evident in his capability to solve complex calculus problems with ease, while struggling with the practical task of programming a smartphone.
Step-by-step explanation:
Don is very good at solving difficult calculus problems, but he has tremendous difficulty programming his new smartphone. Don likely has much higher mathematical intelligence than practical intelligence. The distinction here refers to different types of cognitive abilities that people possess. While Don excels in mathematical reasoning and problem-solving, which is an aspect of mathematical intelligence, he struggles with everyday tasks and technology, which require what is known as practical intelligence.
It is helpful to understand this through the lens of cognitive energy demands. Deliberate, effortful thinking like solving calculus problems requires the brain to use up energy, which is why such tasks can be evolutionarily expensive. This costly energy consumption for rational thought is something evolutionary pressures typically discourage due to the need to conserve energy for survival and reproduction. However, Don's ability in mathematics suggests that, for him, the cognitive load is less burdening in this domain compared to practical tasks like programming a smartphone, which might not come as naturally.
