Sensations
What is the process by which your ears convert sound waves into neural impulses?
Transduction
What is the ability to perceive the color, motion, and form of an object simultaneously called?
Parallel processing
What is the smallest difference in stimulation that a person can detect 50% of the time called?
Difference threshold
What does the term "retinal disparity" refer to in depth perception?
The differences in images between the two eyes that helps perceive depth.
What are the specialized cells in the inner ear that transduce sound vibrations into neural signals?
Hair cells
The process of receiving and representing stimulus energies through the nervous system is called?
Sensation
The perceptual tendency to group together stimuli that are near each other is known as?
Proximity
Which law states that to perceive a difference between two stimuli, they must differ by a constant minimum percentage?
Weber's Law
What is the term for the visual cue where closer objects block the view of distant objects?
Interposition
Why do people with hearing loss in one ear have difficulty locating sounds?
Sound waves strike one ear sooner and more intensely than the other.
What term describes the minimum amount of stimulation needed to detect a stimulus 50% of the time?
Absolute threshold
What is the term for interpreting visual stimuli as an organized whole?
Gestalt
The ability to focus on one specific stimulus while ignoring others is known as?
Selective attention
Which phenomenon describes the brain filling in missing information from the visual field?
Blind spot
What is the term for the phenomenon where a person fails to notice a change in the speaker while focusing on a list of words?
Change blindness
Which type of receptors are most light-sensitive?
Rods
What do we call the influence of previous experiences and expectations on perception?
Perceptual set
What term describes the process of detecting a stimulus that is below the threshold of conscious awareness?
Subliminal perception
What is the perceptual tendency to perceive objects as stable despite changes in sensory input?
Perceptual constancy
Which theory of hearing explains how we perceive different pitches?
Frequency theory
What is the phenomenon called when you become less sensitive to a constant stimulus over time?
Sensory adaptation
Which theory explains the experience of color afterimages, such as seeing green after looking at red?
Opponent-process theory
Which theory suggests that our perception of pain can be affected by the activity of large fibers in the spinal cord?
Gate-control theory
How does a 3-D movie enhance our sense of depth perception?
By simulating retinal disparity
What is the significance of the auditory cortex in processing sound?
It is where auditory information is interpreted after being sent from the ear.
