Basic Principles
Perception
Vision
Hearing
Other Senses
100
When constant exposure to a stimulus leads to decreased sensitivity over time.
Sensory adaptation
100
This type of processing uses prior knowledge, expectations, and experiences to interpret sensory information.
Top-down Processing
100
Light's _________ is the distance from one wave peak to the next.
Wavelength
100
The brain's ability to pinpoint a sound's origin in the environment around us
Sound Localization
100
The process that allows a ballerina to detect the position of different parts of her body
Kinesthetic sense
200
The smallest detectable change in a stimulus.
Just Noticeable Difference
200
What Gestalt Principle is on display here?
Proximity
200
The back of the eye where light is turned into signals. It contains special cells (rods and cones) that help us see.
Retina
200
The higher the frequency of a sound wave, the higher the _____
Pitch
200
The principle that one sense may influence another
Sensory interaction
300
What do we call the conversion of stimulus energies, like sights and sounds, into neural impulses?
Transduction
300
A readiness to perceive things a certain way, based on expectations, emotions, or cultural background
Perceptual set
300
The clear, outer layer at the front of the eye. It helps focus light coming into the eye.
Cornea
300
The coiled, fluid-filled tube in the inner ear that contains the basilar membrane
Cochlea
300
Dizziness and loss of balance could result from the disruption of what sense?
Vestibular sense
400
The minimum intensity of a stimulus that can be detected 50% of the time.
Absolute threshold
400
Lights blinking on and off in sequence, creating the illusion of movement.
Phi-phenomenon
400
According to this theory, the retina contains three types of color receptors (red, green, blue), and their combination allows us to perceive the full color spectrum.
Trichromatic Theory
400
The three small bones of the middle ear
Ossicles
400
Which of these taste sensations is not actually a taste: Sweet, Sour, Spicy, Bitter, Salty, Umami, or Oleogustus
Spicy
500
What principle states that in order to be perceived as different, two stimuli must differ by a minimum percentage rather than a constant amount?
Weber's law
500
The difference between images in the left and right eyes; the brain uses this difference to calculate depth.
Retinal Disparity
500
These photoreceptor cells detect color and are concentrated in the fovea, the center of the retina.
Cones
500
Deafness that occurs due to damage to the outer or middle parts of the ear; sound waves are unable to be sent to the cochlea
Conduction
500
The sensory receptors that detect painful temperatures, pressure, or chemicals are called
Nociceptors
