What concept is illustrated by the following study participants were instructed?
What concept is illustrated by the following study? Participants were instructed to focus on either white or black objects, disregarding the other color. When a red cross passed across the screen, about one third of the subjects did not notice it.

What concept is illustrated by the fact that Congress has the power to introduce and pass laws, and the president has the responsibility to enforce all federal laws? Separation of powers.
Which of the following was demonstrated by the 1998 research of ayabe Kanamura Saito Distel Martínez Gómez & Hudson Group of answer choices?
Which of the following was demonstrated by the 1998 research of Ayabe-Kanamura, Saito, Distel, Martinez-Gomez, & Hudson? The ability to identify an odor, and rate its pleasantness and its intensity, varies cross-culturally.
When a Red Cross passed across the screen about one third of the subjects did not notice it?
Nearly one third of participants in a study did not notice that a red cross passed on the screen because their attention was focused on the black or white figures. (credit: Cory Zanker)
How does the principle of proximity explain why the second sentence makes sense immediately?
How does the principle of proximity explain why the second sentence makes sense immediately, but the first sentence does not? We group letters of a given word together because there are no spaces between the letters, and we perceive words because there are spaces between each word.
What does the place theory of pitch perception suggest quizlet?
This would mean that a given hair cell would fire action potentials related to the frequency of the sound wave. Place Theory. The pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies.
Who suggested the place theory of pitch?
Hermann Ludwig Ferdinand von Helmholtz
What does place theory of pitch perception suggest?
The place theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies. More specifically, the base of the basilar membrane responds best to high frequencies and the tip of the basilar membrane responds best to low frequencies.
What does the place theory of pitch perception?
Place theory is a theory of hearing that states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane. In all cases, neural firing patterns in time determine the perception of pitch.
What does frequency theory explain?
This theory of how we hear sounds states that there are pulses that travel up the auditory nerve, carrying the information about sound to the brain for processing, and that the rate of this pulse matched the frequency of whatever tone you are hearing exactly.
Is Place theory of frequency theory correct?
Place theory is accurate, except that receptive cells along the inner membrane lack independence in response. They vibrate together as suggested by the frequency theory. Sound waves travel along the membrane, peaking at a given region depending on the frequency.
What are the two theories of pitch perception?
Two rival theories have slugged it out over the years: ‘place theory’, in which pitch is determined by which neurons are active, and ‘temporal theory’, in which pitch is determined by how the neurons are active, specifically in terms of their temporal firing patterns.
What is the difference between frequency and place theories of pitch?
Place theory states that the perception of pitch depends on what area of the basilar membrane is vibrating. Frequency theory claims that the perception of pitch depends on the rate at which the entire basilar membrane vibrates.
Which will you hear as the highest pitch?
For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz.
How do you determine pitch?
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, “high” pitch means very rapid oscillation, and “low” pitch corresponds to slower oscillation.
What is tone and pitch?
Pitch is the high or low frequency of a sound. Tone is the color or timbre of pitch. Tone can be described by many different words, including warm, dark, brilliant, ringing, rich, lush, shrill, and strident.
What is the difference between pitch and volume?
Pitch is a measure of how high or low something sounds and is related to the speed of the vibrations that produce the sound. Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations.
What is the difference between pitch and intensity?
Intensity is the amount of energy a sound has over an area. Pitch, which depends on frequency, helps us distinguish between low and high sounds.
Does pitch depend on intensity?
The sense of pitch depends on the intensity of the tone, as shown in the graph; below 1000 Hz, pitch tends to drop with increasing loudness, and above 1000 Hz, tends to rise.
Does pitch affect sound intensity?
slope shows that pitch increases with intensity. point which is a function of both frequency and intensity.
