Question 1

Which of the following is NOT one of the pictorial depth cues?

Accepted Answer

Convergence is not a pictorial depth cue but is a binocular depth cue that comes from the way that our eyes move inward as an object gets closer. The other choices, B) linear perspective, C) relative height, and D) texture gradients are all examples of pictorial depth cues that can be conveyed in a two-dimensional image (such as a painting or photograph).

Question 2

Which theory of colour vision BEST explains why the colour of an afterimage is the complement of the original colour?

Accepted Answer

According to the opponent process theory, there are three pairs of opposing colour channels (red-green, blue-yellow, and black-white) in the visual system. When we stare at a colour for an extended period of time, the cells that respond to that colour become fatigued and send weaker signals to the brain. At the same time, the opposing colour channels become more active. This leads to the perception of an afterimage that is the complement of the original colour. For example, staring at a green image will fatigue the green-sensitive cells and lead to an afterimage that appears red, the opposite of green.

Question 4

The receiving area of a retinal cell is called the

Accepted Answer

The receiving area of a retinal cell is called the receptive field. This is the area on the retina that, when stimulated, will cause a change in the firing rate of a particular neuron. The cone and rod are types of photoreceptor cells in the retina, and the foveal field is a specific region of the retina where there is a high concentration of cones and a high visual acuity.

Question 5

Although located in the eye, the ____________________ is actually a piece of the central nervous system and is responsible for processing images.

Accepted Answer

The answer of Although located in the eye, the ____________________...

Question 6

You are sitting in an arena watching the end of a very close basketball game and you fail to notice that one of the referees has removed his shirt. This an example of

Accepted Answer

This scenario is an example of inattentional blindness, which occurs when an individual fails to perceive an unexpected stimulus that is in plain sight, due to the focus of their attention on another task, event, or aspect of their environment.

Question 7

Hue is to pitch as brightness is to

Accepted Answer

Hue and pitch both refer to the perception of different frequencies of light waves and sound waves, respectively. Similarly, brightness and loudness both refer to the intensity or amplitude of light waves and sound waves.

Question 8

The optic nerves from the inside half of each eye cross over at the ____________________ and then project to the opposite hemisphere of the brain.

Accepted Answer

The answer of The optic nerves from the inside half...

Question 9

Research into the effects of subliminal stimulus suggests that the effect produced by subliminal stimuli is generally ____________________.

Accepted Answer

The answer of Research into the effects of subliminal stimulus...

Question 10

Through ____________________, sensitivity to constant stimuli decreases and people are allowed to ignore the obvious.

Accepted Answer

The answer of Through ____________________, sensitivity to constant stimuli decreases...

Question 11

Which of the following pairs of terms related to the perceived qualities of light and sound result from similar physical properties of light and sound?

Accepted Answer

Both brightness and loudness are related to the intensity or amplitude of light and sound waves, respectively.

Question 12

____________________ colour mixing works by removing some wavelengths of light leaving less light than was originally there while, ____________________ colour mixing works by superimposing lights, putting more light in the mixture than exists in any one light.

Accepted Answer

The answer of ____________________ colour mixing works by removing some...

Question 13

____________________ refers to the relative amount of whiteness in a colour.

Accepted Answer

The answer of ____________________ refers to the relative amount of...

Question 14

The fact that we are generally much more aware of the changes in our sensory environments than we are of the constants is the general idea behind

Accepted Answer

Sensory adaptation refers to the phenomenon wherein our sensory systems adjust to constant or consistent stimulation, resulting in a reduced sensitivity to the stimuli. As a result, we become more aware of changes in our sensory environments rather than the constants. This phenomenon has been extensively studied in the context of vision, hearing, taste, and touch.

Question 15

Perception is ____________________ and involves much more than passively receiving signals from the outside world; it involves the ____________________ of sensory input.

Accepted Answer

The answer of Perception is ____________________ and involves much more...

Question 16

Which of the following is an example of what is meant by perceptual constancy?

Accepted Answer

Perceptual constancy refers to the tendency of objects to be perceived as stable and unchanging despite changes in their appearance due to changes in environmental conditions such as lighting and distance. The fact that a round pie tin always appears round to us, regardless of the angle or distance from which we view it, is an example of perceptual constancy.

Question 17

Sensation begins with a(n) ____________________, or any detectable input from the environment.

Accepted Answer

The answer of Sensation begins with a(n) ____________________, or any...

Question 18

In vision the ____________________ of light affects the perception of brightness, while the ____________________ affects the perception of colour.

Accepted Answer

The answer of In vision the ____________________ of light affects...

Question 19

The visual cortex is to the auditory cortex as the occipital lobe is to the

Accepted Answer

The visual cortex processes visual information and is located in the occipital lobe, while the auditory cortex processes auditory information and is located in the temporal lobe. Therefore, the answer must be a lobe other than the occipital lobe or the temporal lobe, leading to the answer choice of (D) parietal lobe or (B) frontal lobe. However, the parietal lobe is primarily associated with sensory processing and spatial awareness, while the frontal lobe is primarily associated with higher order thinking and decision making. Therefore, the best and most accurate answer is (C) temporal lobe.

Question 20

For any specific type of sensory input a(n) ____________________ is the minimum stimulus intensity that an organism can detect in perceived magnitude of sensation.

Accepted Answer

The answer of For any specific type of sensory input...
