- Sensation and Perception explains the differences between these two processes.
- Absolute Threshold of Sensation. It is also possible for us to get messages that are presented below the threshold for conscious awareness—these are called subliminal messages.
- Weber’s Law and Thresholds. Try It. Perception. While our sensory receptors are constantly collecting information from the environment, it is ultimately how we interpret that information that affects how we interact with the world.
- Bottom-up versus Top-down Processing. Look at the shape in Figure 3 below. Seen alone, your brain engages in bottom-up processing. There are two thick vertical lines and three thin horizontal lines.
Learn the difference between sensation and perception, and how they are related to sensory receptors, thresholds, and subliminal messages. Explore the roles of attention, motivation, and sensory adaptation in perception.
Learn the difference between sensation and perception, and how sensory receptors, thresholds, attention, and adaptation affect our perception of the world. Explore the five senses and their mechanisms, and the role of subliminal messages in influencing our behavior.
This web page is part of a free textbook on psychology that covers the topics of sensation and perception. However, the web page is currently unavailable due to a glitch and requires restarting the browser or visiting the support center.
Learn the difference between sensation and perception, and how they are measured by psychophysics. Explore the concepts of absolute threshold, difference threshold, signal detection, and Weber's law.
Sensation and perception are two separate processes that are very closely related. Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations.
