Sensation and Perception
Sensation is the process of detecting physical stimuli from our environment through our senses (like sight and hearing), while perception is how our brain interprets these sensations to make sense of the world. Psychophysical laws, such as Weber's Law, explain the relationship between the intensity of a stimulus and our ability to notice changes in it. For example, it takes a larger difference in weight to feel that one object is heavier than another as the weights increase. Together, sensation and perception allow us to experience and understand our surroundings effectively.

Sensation is the process by which our sensory organs—like our eyes, ears, and skin—detect stimuli from the environment, such as light, sound, and touch. Perception, on the other hand, is how our brain interprets and organizes these sensory signals to understand and make sense of what we experience. Essentially, sensation is about receiving information, while perception is about interpreting that information to create a meaningful experience. Together, they help us navigate and interact with the world around us.
