100
Detecting energy from the environment and sending it to the brain.
What is sensation?
100
The structure that focuses light by changing shape/accommodation.
What is the lens?
100
The structure where transduction of sound occurs.
What is the cochlea?
100
People who have a greater sense of gustation than the majority of people are called________.
What are supertasters?
100
The process of organizing and interpreting sensory information.
What is perception?
100
The ability to see objects in 3D and judge distance.
What is depth perception?
200
Remy seeing colors while tasting food is an example of this.
What is Synesthesia?
200
This is the place where the optic nerve leaves the eye and no receptor cells are located.
What is the blind spot?
200
The height of sound waves that determines loudness.
What is amplitude?
200
Taste receptors detect these 5 flavors.
What are sweet, sour, salty, bitter, umami?
(bonus: oleogustus = fats)
200
Processing that starts with sensory input and works up to the brain.
What is bottom-up processing?
200
A binocular cue where the brain compares slightly different retinal images.
What is retinal disparity?
300
Diminished sensitivity due to constant exposure to a stimulus.
What is sensory adaptation?
300
The location with the highest density of cones.
What is the fovea?
300
Hearing loss caused by damage to the hair cells or auditory nerve.
What is sensorineural hearing loss?
300
The only sense that bypasses the thalamus.
What is smell / olfaction?
300
The mental framework that influences how we interpret stimuli.
What are schemas OR perceptual set?
300
A monocular cue where closer objects block distant ones.
What is interposition?
400
The minimum stimulus needed to detect a stimulus 50% of the time.
What is absolute threshold?
400
Competing theory explaining afterimages and color pairs like red–green.
What is opponent-process theory?
400
We locate sounds by comparing differences in this between our ears.
What is timing/intensity (sound localization)?
400
The sense that monitors balance using semicircular canals.
What is vestibular sense?
400
We see an object as having the same shape even when viewed from different angles.
What is shape constancy?
400
The idea that a whole is perceived as being more than the sum of its parts.
What is Gestalt?
500
The smallest detectable change in a stimulus.
What is the difference threshold / Just Noticeable Difference?
500
Brain ability to process features (color, motion, shape) simultaneously.
What is parallel processing?
500
In hearing, this is the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of the tone.
What is frequency theory?
500
The sense that tracks body part movement without seeing them.
What is kinesthesis?
500
Failure to notice something obvious when focused elsewhere.
What is inattentional blindness?
500
A human's ability to visually differentiate between an object and its background.
What is Figure-Ground?
600
The principle that change must be proportional to the original stimulus to be noticed.
What is Weber’s Law?
600
Theory explaining color vision due to three types of cones—red, green, and blue.
What is Young Helmholtz/trichromatic theory?
600
Theory that different sound frequencies stimulate different parts of the cochlea.
What is Place Theory?
600
Specialized sensory receptors that detect and transmit pain signals to the brain
What are nociceptors?
600
This phenomenon proves attention is selective: you're able to carry a conversation with your partner in a loud classroom.
What is the cocktail party effect?
600
The tendency to see an unbroken whole even when parts are missing.
What is closure?
