Why is the volley principle important?
Volley Principle: The volley principle reconciles the fact that the cochlear microphonic mimics the sound pressure waves with the implausibility of the temporal code. Wever suggested that while one neuron alone could not carry the temporal code for a 20,000 Hz tone, 20 neurons with staggered firing rates could.
What is the volley principle AP Psychology?
Volley Principle. The principle that relates the experience of pitch to the alternating firing of groups of neurons along the basilar membrane. Conduction Deafness. A form of deafness, usually involving damage to the middle ear, in which there is a loss of conduction of sound vibrations through the ear. Taste Cells.
What is the volley principle in psychology quizlet?
The Volley Principle is an information encoding scheme used in human hearing. Nerve cells transmit information by generating brief electrical pulses called action potentials. The volley principle was proposed to deal with this apparent anomaly between the behaviour of single neurons and groups of neurons.
What is another name for the volley theory?
Also called the platoon-volley theory. Compare frequency theory, place theory.
Why do we need two ears?
With two ears, you are able to hear sounds clearly from both directions. Hearing sound from only one side of the body limits the amount of sound that you can hear clearly from the other side. Having two ears compared with one increases the range which you are able to hear from 180 to 360 degrees.
How do we sense touch AP Psychology?
Our “sense of touch” is actually a mix of distinct skin senses for pressure, warmth, cold, and pain. Touching various spots on the skin with a soft hair, a warm or cool wire, and the point of a pin reveals that some spots are especially sensitive to pressure, others to warmth, others to cold, still others to pain.
Why was the volley principle developed?
In an effort to combat this fault, Ernest Wever and Charles Bray, in 1930, proposed the volley theory, claiming that multiple neurons could fire in a volley to later combine and equal the frequency of the original sound stimulus.
Which of the following is true of cones psychology?
Which of the following is true about cones? Expln:Cones are the sensory receptors that respond to color and send visual information of high acuity or visual sharpness. The cones are located primarily in the center of the retina. Rods are more sensitive than cones to light, and they respond only to black and white.
How do Place theory and frequency theory explain pitch perception?
The place theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies. At frequencies up to about 4000 Hz, it is clear that both the rate of action potentials and place contribute to our perception of pitch.
What characteristics of sound are measurable?
Pitch and loudness, however, are subjective qualities; they depend in part on the hearer’s sense of hearing. Objective, measurable qualities of sound include frequency and intensity, which are related to pitch and loudness.
What does the amplitude of a wave measure?
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium.
What is the volley principle?
The Volley Principle is part of a hearing theory that was proposed by the research team of Weaver and Bray in 1937.
What is volley theory?
Volley theory. Jump to navigation Jump to search. Volley theory states that groups of neurons of the auditory system respond to a sound by firing action potentials slightly out of phase with one another so that when combined, a greater frequency of sound can be encoded and sent to the brain to be analyzed.
What is the place theory in psychology?
Place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane . Therefore, the pitch of a pure tone would be determined by where the membrane vibrates.
