What term describes the ability to think logically and quickly?

The term that describes the ability to think logically and quickly is cognition. Cognition encompasses various mental processes, including perception, memory, and reasoning, which allow individuals to interpret information and make decisions effectively. This ability is essential for problem-solving and adapting to new situations.

In contrast, dementia refers to a decline in cognitive function, which affects memory and reasoning, illustrating how cognition is a crucial aspect of mental health. Being "aware" refers to a state of consciousness about one's surroundings or situation but does not specifically indicate logical reasoning or quick thinking. Dysphagia is a medical term related to difficulty in swallowing, which is not relevant to cognitive processes.
