Question 1

A measurement in cycles per second and that is translated into the auditory quality of pitch is called _.

Accepted Answer

Frequency is the measurement in cycles per second that is translated into the auditory quality of pitch.

Question 2

More recent research on colour transduction has indicated that the opponent-process theory of colour was inaccurate because opponent processes are actually determined NOT by the cones but by the:

Accepted Answer

Opponent processes are determined by the ganglion cells, not the cones, as they process the signals from the cones and create the opponent color signals.

Question 3

The process in which visual information, such as colour, distance, and movement, is simultaneously analyzed is referred to as:

Accepted Answer

Parallel processing is the ability of the brain to simultaneously process incoming stimuli of differing quality, such as color, distance, and movement.

Question 4

The coiled, snail-like tube in the inner ear that is filled with fluid is called the:

Accepted Answer

The cochlea is a coiled, snail-like tube in the inner ear that is filled with fluid. It is responsible for hearing.

Question 5

Individuals with prosopagnosia have difficulty with:

Accepted Answer

Prosopagnosia is a neurological condition characterized by the inability to recognize faces, hence it is related to facial recognition difficulties.

Question 6

Colour blindness is typically assessed by:

Accepted Answer

Colour blindness is typically assessed using tests like the Ishihara test, which involves pictures with coloured dots that form numbers or patterns that can be seen differently by those with colour vision deficiencies.

Question 7

A person who only has a deficiency in the yellow-blue colour system would be called a:

Accepted Answer

A person with a deficiency in the yellow-blue color system is a type of dichromat, specifically tritanopia, which affects the blue-yellow color vision.

Question 8

Cells in the occipital lobe that fire selectively in response to specific visual characteristics are called:

Accepted Answer

Feature detectors are specialized neurons in the occipital lobe that respond to specific features of visual stimuli, such as edges, angles, or movement.

Question 9

The current modern theory of colour sensation uses the trichromatic theory to explain the behaviour of the cones in colour vision while a modified version of another theory emphasizes the role of ganglion cells is used to explain the presence of afterimages and certain types of colour blindness. The theory that emphasizes the role of ganglion cells is called the theory.

Accepted Answer

The opponent-process theory emphasizes the role of ganglion cells in processing color information, explaining phenomena like afterimages and certain types of color blindness.

Question 10

Which one of the following statements is false?

Accepted Answer

The claim that subliminal messages in movie theatres increased pop and popcorn sales is based on a study by James Vicary in the 1950s, which was later revealed to be a hoax. There is no scientific evidence supporting this claim.

Question 11

The amplitude of a sound wave determines which sensory quality?

Accepted Answer

The amplitude of a sound wave is related to the loudness of the sound; higher amplitude means louder sound.

Question 12

Research has shown that subliminal presentations of aggressively toned words cause people to judge

Accepted Answer

Subliminal presentations of aggressively toned words can prime individuals to perceive ambiguous behaviors as more aggressive due to the influence of these words on their subconscious judgment.

Question 13

A subliminal stimulus is best defined as being:

Accepted Answer

A subliminal stimulus is not perceived consciously and well below the absolute threshold.

Question 14

You are standing on a sidewalk and a bus drives past you with a billboard on the side. With seemingly no effort, your visual system is able to simultaneously process
Information about the words on the billboard, the colour and speed of the bus, and how far away from you the bus is. This simultaneous analyzing of information related to
Different visual characteristics is called:

Accepted Answer

Parallel processing is the ability of the brain to simultaneously process multiple aspects of a visual scene, such as color, motion, shape, and depth.

Question 15

The two physical characteristics of sound waves are:

Accepted Answer

Amplitude and frequency are the two physical characteristics of sound waves. Amplitude refers to the height of the wave, while frequency refers to the number of waves that pass by in a given amount of time.

Question 16

Janet likes to play her stereo very loud on Saturday nights. Her upstairs neighbour keeps complaining that the rock music is causing his apartment walls to shake. This complaint is valid, as the amplitude of the sound waves _.

Accepted Answer

The amplitude of sound waves influences the pressure of waves in the air, which can cause physical vibrations like shaking walls.

Question 17

Frequency determines the pitch of a sound, while amplitude determines the of a sound.

Accepted Answer

Amplitude determines the loudness of a sound, as greater amplitude results in a louder sound.

Question 18

A person with a deficiency in only one of the colour systems, such as red-green, would be considered a dichromat, while someone who is colour-blind in two colour systems is labelled _.

Accepted Answer

A monochromat is someone who is colour-blind in two colour systems, meaning they can only perceive one colour system.

Question 19

People with normal colour vision are referred to as:

Accepted Answer

People with normal colour vision are referred to as trichromats because they have three types of cone cells in their retinas, which allow them to perceive a wide range of colours.

Question 20

To account for the colour transduction process, the dual-process theory of colour combines elements of the trichromatic theory and the _ theory.

Accepted Answer

The dual-process theory of color vision combines the trichromatic theory, which explains how the three types of cones in the retina detect different wavelengths of light, with the opponent-process theory, which explains how these signals are processed in the brain to perceive color.
