Sensation and Perception

Receptors

Specialized cells that convert physical energy in the environment to electrical energy that can be transmitted as nerve impulses to the brain

Transduction

Conversion of 1 form of energy to another (sensory receptors are biological transductors)

Sensory Adaptation

Repetitive/unchanged stimulation eventually disappears due to adaptation (ex.: perfume smell, cold water in a pool, food smells at a restaurant, noise of a projector, etc.)

Sensory Interaction

How senses influence one another (smell & taste have the most interaction between each other)

McGurk Effect

“Ba vs. Fa;” seeing mouth movements helps dictate what we hear (interaction between vision & hearing)

Synesthesia

Brain circuits of 2+ senses are jointly d& stimulation from 1 sense triggers an experience in another (ex.: auditory-tactile, Grapheme-color, sound-color, number-form); could be cause by genetics, faulty pruning, etc.
