Question 1

Which of the following is NOT considered a monocular cue for depth?

Accepted Answer

Convergence is a binocular cue for depth perception, involving the inward angle of the eyes focusing on a nearby object.

Question 2

Consider the following image: // \ // .We are likely to interpret this as three sets of two lines each rather than six separate lines due to the Gestalt law of ____________.

Accepted Answer

The Gestalt law of proximity explains how we perceive elements close to each other as part of a group, leading us to see three sets of two lines rather than six separate lines.

Question 3

The Weber Fraction for loudness is 1/20.So let's say I get you to listen to some music played at 100 decibels.In order for you to tell that a second piece of music was louder,I would need to play it at

Accepted Answer

The Weber Fraction formula states that the ΔI/I (the difference in intensity needed to perceive a difference in loudness) is equal to the Weber Fraction (1/20). Therefore, to calculate the difference in intensity needed to perceive a difference, we take the initial intensity (100 dB) and multiply it by the Weber Fraction (1/20), which gives us 5 dB.

This means that in order to perceive a difference, we need to increase the intensity by 5 dB. Therefore, the second piece of music would need to be played at 105 dB (100 dB + 5 dB) in order for it to be perceived as louder.

Choice D is the best answer.

Question 4

You are going on a blind date because a friend convinced you that this person was perfect for you.Your friend tells you that your date is good looking,funny and a really good listener.From what you have read in the text,your perception of your date will probably be influenced by

Accepted Answer

Your perception of the date will likely be influenced by your perceptual sets, or expectations and preconceptions about what the person will be like. Your friend's description of the date as good looking, funny, and a good listener may cause you to perceive these traits in the individual, even if they are not objectively present or emphasized during the date.

Question 5

If you have normal colour vision,you are referred to as a ___________,whereas if you are red/green or yellow/blue colour-blind,you are referred to as a ___________.

Accepted Answer

Individuals with normal color vision are referred to as trichromats because they can perceive all three primary colors (red, green, and blue). Those who are red/green or yellow/blue color-blind are referred to as dichromats, meaning they can effectively perceive only two of the primary colors.

Question 6

Let's say that you run a deprivation experiment in which kittens were raised from birth in an environment containing only horizontal stripes.Based on the research by Blakemore and Cooper (1970),how will this affect cells in their visual cortex?

Accepted Answer

The experiment by Blakemore and Cooper showed that visual cortex cells in kittens raised in an environment with only horizontal stripes became responsive only to horizontal lines, demonstrating the impact of environmental exposure on neural development.

Question 7

In the process of trying to recognize a stimulus,we compare the current stimuli against mental representations known as

Accepted Answer

The mental representations we use to recognize stimuli are known as perceptual schemas. Option A is incorrect because sensory icons refer to the brief visual or auditory images that persist after a stimulus is removed. Option B and C are not commonly used terms in the field of perception. Option E is not a valid term for describing the recognition process.

Question 8

If you had deafness due to damage to your cochlea,you would have which kind of deafness?

Accepted Answer

The answer of If you had deafness due to damage...

Question 9

_______________ lets us know where our body segments are in relation to one another (e.g.is my elbow straight or bent?),whereas _______________ tells us how our whole body is oriented in relation to the world (e.g.which way is down or which way am I rotating?).

Accepted Answer

Proprioception lets us know the position of our body parts in relation to each other, while the vestibular sense informs us about our overall orientation in space, including balance and direction.

Question 10

If your eye were too long front to back,such that a focused image falls in front of your retina and you see a blurry image,you are said to have _____________.

Accepted Answer

Myopia, also known as nearsightedness, occurs when the eye is too long relative to the focusing power of the cornea and lens, causing light rays to focus at a point in front of the retina rather than directly on its surface. This results in a blurry image for distant objects.

Question 11

You are blindfolded and asked to taste a cup of coffee to determine if it contains cream.Eight times out of 10 you correctly identified the presence of cream,but twice you said that cream was present when there was none there.According to signal detection theory,your correct responses are called ___________ and your incorrect responses are called __________.

Accepted Answer

According to signal detection theory, correctly identifying a stimulus when it is present is referred to as a hit. Incorrectly identifying a stimulus as present when it is not actually there is referred to as a false alarm. Therefore, the correct responses in this scenario are hits and the incorrect responses are false alarms, which corresponds to choice D.

Question 12

Which of the following cells is NOT found in the retina?

Accepted Answer

Hair cells are not found in the retina. They are actually found in the cochlea of the inner ear and are responsible for detecting sound waves. Rods, cones, horizontal cells, and ganglion cells are all types of cells found in the retina.

Question 13

Alexis was born with a rare hereditary condition such that in her retina she has no rod photoreceptors,but only cone photoreceptors.Given the anatomy of her retina,which of the following is true regarding her vision?

Accepted Answer

Rod photoreceptors are responsible for vision in low light conditions, so without them, Alexis would have very poor vision in situations with low levels of light. However, because she has cone photoreceptors, she can still see color and have good visual acuity in the central fovea area. She may have difficulty adjusting to very bright light, but this is not as significant as her lack of rod photoreceptors. She is not necessarily color-blind for the red-green color pair, as she still has cone photoreceptors that can respond to these colors in adequate lighting conditions.

Question 14

Today's best understanding of how colour vision works is based on which theory?

Accepted Answer

The answer of Today's best understanding of how colour vision...

Question 15

Hold your hand a few feet away from your face.Now alternate between looking at your hand with only your right eye and then only with your left eye.You will notice that each eye has a slightly different view of your hand and the scene behind it.Special detection cells in your brain tuned to ______________ allow your brain to extract depth information from the visual scene,thus informing where your hand is in relation to the stuff behind it.

Accepted Answer

Binocular disparity refers to the slight difference in the images seen by each eye, which allows the brain to extract depth information and perceive the relative distance between objects in the visual scene.

Question 16

If you are extremely sensitive to stimuli in a particular sensory system,we would expect

Accepted Answer

A lower than normal absolute threshold means that it takes less intensity of a stimulus to be detected. Therefore, if someone is extremely sensitive to stimuli in a particular sensory system, we would expect them to have a lower than normal absolute threshold for that system.

Question 17

The jnd value for weights is approximately 1/50.If you can lift a weight of 500 grams,a comparison weight must weigh at least _________ gram(s)more in order for you to be able to judge it as heavier.

Accepted Answer

The formula for jnd value for weights is ΔW/W = 1/50. Therefore, ΔW = 1/50 x W. 
Substituting W = 500 grams, we get ΔW = 1/50 x 500 = 10 grams. This means that to judge a weight as heavier, a comparison weight must weigh at least 10 grams more. Hence, the correct answer is A) 1/50 x 500.

Question 18

The Young-Helmholtz trichromatic theory states that we can see colour because the human eye has ____ different types of light detecting cells that _________________.

Accepted Answer

The Young-Helmholtz trichromatic theory states that there are three different types of light detecting cells in the human eye that are tuned to red, green, and blue light. This theory explains how we are able to perceive the full range of colors in the visible spectrum. Choice A is partially correct, but it also includes black and white light, which are not colors. Choice B is incorrect because it only includes three colors, and Choice D is incorrect because it includes yellow, which is not a primary color of light. Choice E is incorrect because it does not address the question of how we see color.

Question 19

The human auditory system is capable of localizing sound direction using differences of _____________ between the two ears.

Accepted Answer

The human auditory system uses both differences in intensity (loudness) and timing (arrival time) of sounds between the two ears to localize sound direction. Differences in frequency (pitch) are not typically used for sound localization. Therefore, option D, "both intensity and timing are correct," is the best choice.

Question 20

According to the Gestalt principle of ___________,we have a tendency to perceive objects that are near one another as belonging together.

Accepted Answer

The law of proximity states that objects that are near one another tend to be grouped together in our perception. This means that we tend to see objects that are close to each other as belonging together as a cohesive unit.
