Sensation and Perception in Psychology Quiz

The vestibular system detects changes in body position and movement, helping maintain balance and spatial orientation.

The retina contains photoreceptor cells called rods and cones, which are responsible for detecting light and converting it into neural signals.

The phi phenomenon is a perceptual illusion where two stimuli are presented in rapid succession, creating the perception of a single, continuous motion or image.

Difference threshold is the minimum difference between two stimuli required for an individual to perceive them as different, also known as the just noticeable difference (JND).

Shape constancy is the tendency to perceive an object as maintaining its shape, size, and color despite changes in the angle of viewing or illumination.

Threshold is the minimum amount of stimulation needed to detect a sensory input, beyond which a sensation is experienced.

The trichromatic theory proposes that color vision is based on three primary colors: red, green, and blue, with other colors perceived through their combinations.

Transduction is the process by which sensory receptors convert environmental stimuli into neural signals that can be interpreted by the brain.

Umami is the taste sensation associated with amino acids like glutamate, often described as savory or meaty.

Sensory adaptation refers to the diminished sensitivity to a constant or unchanging stimulus over time, allowing us to focus on new or changing stimuli.

Retinal disparity, a binocular cue, refers to the difference in the image cast on each retina, allowing for depth perception.

Closure is the perceptual tendency to fill in gaps in sensory information, completing a whole figure or object.

Perception is the process of organizing and interpreting sensory information, allowing us to make sense of our surroundings and experiences.

Continuity, a principle of Gestalt psychology, suggests that we tend to perceive objects as continuous and smooth entities, rather than fragmented parts.

Sound localization is the ability to determine the location of a sound source in space, relying on cues such as interaural time differences and interaural level differences.
