Question 1

In general, _____ produces illusions.
A)habitual eye movements
B)perceptual habits
C)size and shape constancy
D)all of these combine to

Accepted Answer

All of these factors can contribute to producing illusions. Habitual eye movements can cause illusions such as the motion aftereffect, perceptual habits can lead to biases in interpretation, and size and shape constancy can create illusions of size and orientation.

Question 2

The apparent movement in motion pictures is caused by an illusion called
A)stroboscopic movement.
B)motion parallax.
C)relative motion.
D)the Müller-Lyer illusion.

Accepted Answer

Stroboscopic movement is the illusion of continuous motion in a sequence of rapidly presented images. This phenomenon is what makes it seem like there is movement in motion pictures, despite the fact that they are just a series of still images shown in quick succession.

Question 3

The Müller-Lyer illusion is
A)based upon experience with the edges and corners of rooms and buildings.
B)based solely on figure-ground relationships.
C)experienced similarly in all cultures.
D)only present with arrows and lines less that one foot in length.

Accepted Answer

The answer of The Müller-Lyer illusion is
A)based upon experience with...

Question 4

Individuals who have Charles Bonnet syndrome
A)are partially blind.
B)are mentally disturbed.
C)lack the ability to engage in reality testing.
D)are characterized by all of these.

Accepted Answer

Individuals with Charles Bonnet syndrome have some degree of vision loss or impairment, but are not necessarily mentally disturbed or unable to engage in reality testing.

Question 5

The Müller-Lyer illusion is best explained by
A)size-distance invariance.
B)perceptual habits.
C)a lifetime of experience with the corners of rooms and buildings.
D)all of these.

Accepted Answer

The Müller-Lyer illusion is best explained by a combination of factors including size-distance invariance, perceptual habits, and a lifetime of experience with the corners of rooms and buildings, which all contribute to how we perceive the lengths of lines in this illusion.

Question 6

If you think you see a three-foot-tall butterfly, you can confirm you are hallucinating by trying to touch its wings.You are engaging in
A)perceptual expectancy.
B)perceptual evaluation.
C)perceptual verification.
D)reality testing.

Accepted Answer

Reality testing is the process of determining whether a perception is real or a hallucination. By trying to touch the butterfly's wings, you can confirm if the perception is real or not. Therefore, the best choice is D, reality testing. Perceptual expectancy refers to the tendency to perceive things based on expectations, while perceptual evaluation involves analyzing a perceived object based on its features. Perceptual verification refers to confirming a perception based on pre-existing beliefs or expectations. None of these options accurately describe the situation described in the question.

Question 7

Mark has been diagnosed with paranoid schizophrenia.In order to sort out which of his experiences are perceptions and which are hallucinations, he must engage in
A)stroboscopic movement.
B)reality testing.
C)perceptual reconstruction.
D)illusionary adaptation.

Accepted Answer

Reality testing involves sorting out what is real and what is not. This is particularly important for individuals with paranoid schizophrenia who may experience intense and disturbing hallucinations. By engaging in reality testing, Mark can begin to distinguish between his perceptions and hallucinations, allowing him to better manage his symptoms and maintain a sense of control over his experiences.

Question 8

Upon seeing the Fraser's spiral, most people must careful trace one of the circles to confirm what is "real" in the design.This is an example of
A)perceptual expectancy.
B)perceptual evaluation.
C)perceptual verification.
D)reality testing.

Accepted Answer

Fraser's spiral is an optical illusion that tricks the brain into seeing a spiral when there are only concentric circles. Reality testing involves checking the actual physical reality to confirm what is perceived, which is what people do when they trace the circles.

Question 9

Which of the following is NOT a characteristic of a person who has Charles Bonnet syndrome?
A)They are partially blind.
B)They are mentally disturbed.
C)They are capable of engaging in reality testing.
D)They experience "sane hallucinations."

Accepted Answer

Charles Bonnet syndrome is a condition where people with partial blindness or visual impairment experience vivid hallucinations that are not related to any psychological condition. The person is aware that these hallucinations are not real and is able to engage in reality testing. It is not related to any mental disturbance or psychiatric illness. Therefore, option B is not a characteristic of a person with Charles Bonnet syndrome.

Question 10

Which of the following illusions involves a horizontal line with arrowheads at each end appearing to be shorter than a horizontal line with open V's at each end of the line?
A)the Poggendorff illusion
B)the Munker-White illusion
C)the Müller-Lyer illusion
D)the Hering illusion

Accepted Answer

This illusion is known as the Müller-Lyer illusion, which involves two horizontal lines of equal length, but with different sets of arrowheads or V's on each end. The line with arrowheads at each end appears shorter than the line with open V's at each end, despite being the same length.

Question 11

Which of the following is a major symptom of psychosis, dementia, epilepsy, migraine headaches, alcohol withdrawal, and drug intoxication and are one of the clearest signs that a person has "lost touch with reality"?
A)illusions
B)hallucinations.
C)stroboscopic movement
D)reality testing

Accepted Answer

Hallucinations are a major symptom of all the listed conditions and are one of the clearest signs that a person has "lost touch with reality." Illusions are also a symptom of some of these conditions, but not all, and stroboscopic movement and reality testing are not major symptoms of any of these conditions.

Question 12

_____ refers to the illusory motion perceived when objects are shown in rapidly changing positions.
A)Stroboscopic movement
B)Motion parallax
C)Relative motion
D)The Müller-Lyer illusion

Accepted Answer

Stroboscopic movement refers to the illusion of motion when objects are shown in rapidly changing positions. This phenomenon occurs when a series of still images are presented in quick succession, creating the perception of movement. Examples of stroboscopic movement include the illusion of a moving picture in flipbooks, the motion of a zoetrope, and the appearance of animation in movies and video games.

Question 13

Jonathan is suffering from Charles Bonnet syndrome.He tells his daughter that he wishes that he would stop seeing these "imaginary" animals in his house.Jonathan is experiencing
A)stroboscopic movement.
B)illusions.
C)sane hallucinations.
D)delusions.

Accepted Answer

The answer of Jonathan is suffering from Charles Bonnet syndrome.He...

Question 14

Selena keeps thinking that she "sees" someone following her, but there is really no one there.This is an example of
A)a hallucination.
B)an illusion.
C)a figure-ground.
D)the Müller-Lyer illusion.

Accepted Answer

Seeing someone following Selena when there is nobody there is indicative of a hallucination, which is a perception of something that is not present in reality.

Question 15

TV cartoons are made up of thousands of still pictures, but we see motion in these cartoons because of
A)motion parallax.
B)linear perspective.
C)stroboscopic movement.
D)the Müller-Lyer illusion.

Accepted Answer

TV cartoons create the illusion of motion through stroboscopic movement, also known as the phi phenomenon. Our brain sees a rapid succession of still images and interprets them as continuous motion.

Question 16

Reality testing is defined as
A)obtaining additional information as a check on the accuracy of one's perceptions.
B)an initial guess regarding how to organize a stimulus pattern.
C)changes in perception that can be attributed to prior experience.
D)the well-established patterns of perceptual organization and attention.

Accepted Answer

Reality testing involves checking the accuracy of one's perceptions by obtaining additional information. This can help to distinguish between what is real and what is imagined or distorted.

Question 17

Regarding Charles Bonnet syndrome, which of the following statements is FALSE?
A)This syndrome is a rare condition which afflicts mainly older people who are partially blind, but not mentally disturbed.
B)People with this syndrome may "see" people, animals, building, plants, and other objects appear and disappear in front of their eyes.
C)People with this syndrome experience "sane hallucinations."
D)People with this syndrome have an inability to engage in reality testing.

Accepted Answer

People with Charles Bonnet syndrome do not have an inability to engage in reality testing. They are aware that the visual hallucinations they are experiencing are not real.

Question 18

Obtaining additional information as a check on the accuracy of one's perceptions is called
A)perceptual expectancy.
B)perceptual set.
C)reality testing.
D)perceptual verification.

Accepted Answer

Reality testing involves obtaining additional information to check the accuracy of our perceptions. Perceptual expectancy and perceptual set refer to our expectations and biases that influence perception, while perceptual verification is the tendency to verify or confirm our existing beliefs or expectations.

Question 19

The lights used on dance floors cause an illusion in which it "freezes" dancers in particular positions when it flashes, which is the reverse of the illlusion known as
A)motion parallax.
B)linear perspective.
C)stroboscopic movement.
D)the Müller-Lyer illusion.

Accepted Answer

The illusion created by the dance floor lights is stroboscopic movement, which is a visual phenomenon where a series of still images presented in quick succession creates the illusion of continuous motion. This is the reverse of the Müller-Lyer illusion, which is a visual illusion where two lines of equal length appear to be different due to the addition of arrowheads on the ends of one line, creating a sense of perspective. Motion parallax and linear perspective are also visual illusions related to perception of depth and motion, but they are not directly related to the dance floor light illusion.

Question 20

_____ is a rare condition, which afflicts mainly older people who are partially blind but not mentally disturbed.They may "see" people, animals, building, plants, and other objects appear and disappear in front of their eyes.
A)Paranoid schizophrenia
B)Charles Bonnet syndrome
C)Klinefelter's syndrome
D)Turner's syndrome

Accepted Answer

The condition described is Charles Bonnet syndrome, a rare condition that affects older people who are partially blind. It causes them to have visual hallucinations of objects, people, and animals that appear and disappear in front of their eyes. Paranoid schizophrenia is a mental disorder characterized by paranoid delusions and hallucinations among other symptoms, and Klinefelter's and Turner's syndromes are genetic disorders that affect sex chromosomes.
