Sensation And Perception | Must See |

Sensation provides the "bricks," while perception is the "architect" that builds the house. Together, they allow us to navigate and react to a complex, ever-changing environment.

Diminished sensitivity as a consequence of constant stimulation (e.g., stopping noticing the smell of a room after being in it for ten minutes).

Absolute Threshold: The minimum intensity needed to detect a stimulus 50% of the time. Sensation and Perception

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

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. Sensation provides the "bricks," while perception is the

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

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. Absolute Threshold: The minimum intensity needed to detect

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
