Using prior knowledge, experiences, and expectations to interpret sensory info (concept-driven). 3. Principles of Organization Sensation and Perception

Starting with the individual pieces of sensory info and building up to a final image (data-driven). Absolute Threshold: The minimum intensity needed to detect

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. Sensation is the physical process of collecting data

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.

Filling in gaps to create a complete, whole object. 4. Influencing Factors Perception is subjective and can be influenced by:

The critical step where physical energy is transformed into electrical impulses the brain can understand. Thresholds:
