These retinal receptors detect color and fine detail in bright light.
What are cones?
The loudness of a sound is measured in these units.
What are decibels?
This skin sense allows us to detect pressure, warmth, cold, and pain.
What is the tactile sense?
This type of processing begins with sensory receptors and moves upward to the brain.
What is bottom-up processing?
This Gestalt principle states that we group nearby objects together.
What is proximity?
This part of the eye controls how much light enters.
What is the pupil?
This inner-ear structure transforms vibrations into neural impulses.
What is the cochlea?
This sense helps maintain balance and body orientation.
What is the vestibular sense?
This processing uses prior knowledge and expectations to interpret stimuli.
What is top-down processing?
This principle explains why we perceive smooth, continuous patterns.
What is continuity?
This theory explains color vision through red-green, blue-yellow, and black-white pairings.
What is the opponent-process theory?
This theory explains pitch perception based on sound wave frequency.
What is frequency theory?
This sense provides feedback about the position of body parts.
What is proprioception?
This concept explains why we perceive objects as the same size despite changes in distance.
What is size constancy?
This monocular cue allows depth perception by comparing object size.
What is relative size?
This term refers to the dimension of light energy that determines brightness.
What is intensity?
This theory explains how pitch is determined by where vibrations occur on the basilar membrane.
What is place theory?
This sense is closely linked to memory and emotion and bypasses the thalamus.
What is olfaction (smell)?
This tendency causes expectations to influence perception.
What is perceptual set?
This depth cue occurs when closer objects block farther ones.
What is interposition?
This structure sends visual information from the retina to the brain.
What is the optic nerve?
These three bones transmit sound waves from the eardrum to the cochlea.
What are the ossicles?
This phenomenon occurs when one sense influences another.
What is sensory interaction?
This perception principle explains why experiences and context shape interpretation.
What is context effect?
This Gestalt concept refers to the organization of visual scenes into objects and backgrounds.
What is figure-ground?
