Sensation and Perception

Sensation and Perception are how we are able to interpret the world. Sensation refers to how our senses receives information through touch, taste, sight, sound and smell - and sends them to the brain. This is where Perception is formed. Perception is the way we interpret these sensations, and make sense of your environment. You can feel warmth, see brightness, hear your alarm clock ringing… your perception tells you it’s the morning, and it’s time to wake up. Perception involves a degree of interpretation, and is often based on previous experiences. In this image, Sensation relays the black and white shapes, but perception tells us its a portrait. But, do you see a young lady, or an old woman? You’ll find that your perception can suddenly change, demonstrating how perception can be changed.   That is how optical illusions can trick our eyes.   Our brains feel the need to interpret information. It wants to find patterns and organize information so that it becomes useful. This is called the Gestalt effect, the sum, or whole, is more than the sum of it’s part. Alone, these lines and shapes are parts of circles and connected lines, placed at an angle. But in this arrangement, a white triangle appears at the center.
