What is the Difference Between Cognition and Perception?

🆚 Go to Comparative Table 🆚

The main difference between cognition and perception lies in the scope and nature of the two processes.

Perception is the process that allows us to use our senses (sight, hearing, touch, taste, and smell) to make sense of the information around us through organization, identification, and interpretation. It is responsible for conveying correct information about our immediate surroundings. Perception can be defined as a cognitive skill or ability, which assists in enhancing the quality of cognitive abilities.

Cognition, on the other hand, involves a variety of mental processes such as attention, memory, reasoning, problem-solving, and decision-making. It encompasses a broader range of skills and processes, including forming beliefs, making decisions, and solving problems based on existing information.

Recent research has shown that higher-order cognitive processes, such as desires and motivations, can significantly influence basic perceptual processes, altering our basic visual perception. This suggests that there may not be a sharp division between cognition and perception, as they seem to share information and influence each other. However, the distinction between the two remains an important aspect of understanding human information processing and decision-making.

Comparative Table: Cognition vs Perception

Here is a table outlining the differences between cognition and perception:

Feature Cognition Perception
Definition Cognition refers to the mental processes involved in gaining knowledge and understanding through thought, experience, and the senses. Perception is the process by which individuals use one or more of their five senses—sight, hearing, touch, smell, and taste—to gather information about their environment.
Scope Cognition encompasses a wide range of mental processes, including perception, attention, memory, learning, and decision-making. Perception is a part of the cognitive process and is focused on the sensory aspects of understanding.
Role Cognition is responsible for forming beliefs, making decisions, and reasoning. Perception puts us in contact with our present surroundings, allowing us to experience and interpret our environment.
Interconnectedness Perception and cognition are interconnected, as perception provides the sensory input that cognition processes to form beliefs, make decisions, and reason. The unified approach to perception and cognition suggests that some systems use sensory activation inputs directly in perception, conceptualizing parts of the raw sensory signal.

In summary, cognition is a broader term that encompasses various mental processes, including perception. Perception, on the other hand, is the specific process by which we gather information about our environment through our senses. Both cognition and perception are interconnected and essential for understanding and interacting with the world around us.
