Study Notes

Transduction and Sensory Systems

Transduction: The process of converting stimuli into signals that can be interpreted by the central nervous system.
Electrochemical Interaction: Combination of electrical impulses and chemical signaling that facilitates communication within the nervous system.

Theories of Color Perception

Opponent Process Theory: Proposes that color vision is the result of three opposing pairs (e.g., red-green, blue-yellow) that create the full spectrum of color perception.

Depth Perception Cues

Binocular Cues: Include stereopsis, retinal convergence, and binocular disparity; these cues allow for depth perception by comparing images from both eyes.
Monocular Cues: Include relative size, texture gradient, interposition, linear perspective, vanishing point, and motion parallax; these cues provide depth information from a single eye perspective.

Theories of Sound Perception

Place Theory: Suggests sound perception is based on the specific location of frequency vibrations along the basilar membrane in the inner ear.
Frequency Theory: Argues that the frequency of sound waves corresponds to the rate of nerve impulses sent to the brain.

Sensory Organs and Their Functions

The Nose (Olfaction): Involves the olfactory epithelium, responsible for the sense of smell.
The Tongue (Gustatory): Contains taste buds that detect five basic tastes: sour, sweet, salty, bitter, and umami.
The Skin: Contains tactile receptors that facilitate the sense of touch and detect pressure, temperature, and pain.

System for Balance and Movement

Vestibular System: Critical for maintaining balance and spatial orientation.
Kinesthetic System: Monitors body position and movement through muscle and joint feedback.
