Sensation
The process of converting physical stimuli into neural signals.
Perception
The interpretation of sensory information to form a mental representation of the environment.
Transduction
The conversion of one form of energy into another, specifically physical stimuli into neural signals.
Adaptation
The process where sensory neurons become less sensitive to a constant stimulus over time.
Feature Detectors
Neurons in the brain that respond selectively to specific features of the environment, such as edges and angles.
Absolute Threshold
The minimum intensity of a stimulus that can be detected 50% of the time.
Just-Noticeable Difference (JND)
The smallest change in stimulus intensity that can be detected 50% of the time.
Weber's Law
The principle that the perceived change in a stimulus is proportional to the original intensity of the stimulus.
Trichromatic Theory
The theory that color perception is based on three primary colors: red, green, and blue.
Opponent-Process Theory
The theory that color perception is controlled by pairs of opposing colors; when one color is stimulated, the other is inhibited.
Dorsal Stream
The pathway in the brain that processes the 'where' of objects, guiding actions towards them.
Ventral Stream
The pathway in the brain responsible for the 'what' of object recognition.
Conductive Hearing Loss
Hearing loss due to problems in the external or middle ear, often treatable with hearing aids.
Sensorineural Hearing Loss
Hearing loss caused by damage to the inner ear or auditory nerve, often due to noise exposure.
Gate Control Theory
The theory that the perception of pain is controlled by a 'gate' in the spinal cord which can be closed by the presence of other sensory information.
Proprioception
The awareness of body position relative to one another and the environment.
Interoception
The perception of the internal state of the body, including sensations coming from internal organs.
Gestalt Principles
Rules that explain how we organize visual information into meaningful wholes, such as figure-ground and closure.
Depth Perception
The ability to perceive the world in three dimensions and judge distance.
Binocular Depth Cues
Depth cues that rely on the use of both eyes, such as retinal disparity and convergence.
Monocular Depth Cues
Depth cues that can be perceived with one eye, such as size perspective and motion parallax.
Perceptual Constancy
The tendency to perceive objects as stable and unchanging despite changes in sensory input.
