Cognition refers to the mental processes involved in obtaining knowledge and awareness of one's environment. This includes thinking, reasoning, decision making, and problem solving. Thinking involves manipulating mental representations of information to find answers and can be concrete, involving actual objects and events, or abstract, involving concepts and generalizations. Reasoning transforms information to reach conclusions through inductive or deductive logic. Decision making selects the best option from available choices based on factors like perception and experience. Problem solving is a planned process of overcoming difficulties by defining the problem, collecting relevant data, organizing information, hypothesizing solutions, and applying and reviewing the best solution.
