Difference Threshold (Just Noticeable Difference): The minimum change in a stimulus required for a person to detect that a change has occurred. Perception: The Interpretation
Diminished sensitivity as a consequence of constant stimulation (e.g., stopping noticing the smell of a room after being in it for ten minutes).
Using prior knowledge, experiences, and expectations to interpret sensory info (concept-driven). 3. Principles of Organization Sensation and Perception
Report: Sensation and Perception 1. Introduction Sensation and perception are the two fundamental processes that allow us to experience the world. While often used interchangeably, they represent distinct stages of processing environmental stimuli. 2. Defining the Core Concepts Sensation: The Input
The critical step where physical energy is transformed into electrical impulses the brain can understand. Thresholds: While often used interchangeably
Sensation is the physical process of collecting data from the environment. Sensory receptors (in the eyes, ears, nose, tongue, and skin) detect physical energy—such as light waves or sound vibrations—and convert it into neural signals.
The environment or surrounding stimuli can change how we perceive an object (e.g., a tall person looks average next to a professional basketball player). 5. Conclusion Sensation and Perception
Perception is the psychological process of organizing and interpreting those neural signals. It is how the brain makes sense of the "raw data" provided by sensation.
