Question 1

Regarding Charles Bonnet syndrome, which of the following statements is FALSE?
A)This syndrome is a rare condition that 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 show a lack of ability to engage in reality testing.

Accepted Answer

Charles Bonnet syndrome is characterized by visual hallucinations in individuals who are often partially sighted but mentally healthy. They retain the ability to distinguish these hallucinations from reality, which means they can engage in reality testing, contrary to what option D suggests.

Question 2

You are at a carnival and go into a fun house in which mirrors create distorted images of you and your friends, while flashing lights cause apparent "movements of objects" where there is no movement. These are examples of
A)sane hallucinations.
B)illusions.
C)figure-ground reversible figures.
D)contiguity.

Accepted Answer

These are examples of illusions, which are perceptions that misrepresent physical stimuli. The mirrors and flashing lights do not actually change your appearance or cause objects to move; they merely distort your perception of reality.

Question 3

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

Accepted Answer

The answer of Upon seeing the Fraser's spiral, most people...

Question 4

Peter, who uses PCP, sees "flaky black smoke falling from the ceiling." Peter is experiencing a
A)visual hallucination.
B)visual illusion.
C)perceptual reconstruction.
D)sane hallucination.

Accepted Answer

Peter is experiencing a visual hallucination, which is a perception of seeing something that is not present in reality, often induced by substances like PCP.

Question 5

Chao has schizophrenia and continually "hears" a voice shouting, "Buckets of blood!" when there is no one around and no radio or television is turned on. Chao is experiencing a(n)
A)auditory hallucination.
B)vestibulary illusion.
C)sane delusion.
D)sane hallucination.

Accepted Answer

Chao is experiencing an auditory hallucination, which is a false perception of sound, typically voices, that occurs in the absence of an external stimulus. This is a common symptom of schizophrenia.

Question 6

An imaginary perception, such as seeing, hearing, or smelling something that does not exist in the external world, is called a(n)
A)illusion.
B)hallucination.
C)stroboscopic movement.
D)Müller-Lyer illusion.

Accepted Answer

Hallucination is the correct term for an imaginary perception where an individual sees, hears, or smells something that doesn't actually exist in the external world. Illusions, on the other hand, are misinterpretations of real external stimuli. Stroboscopic movement and the Müller-Lyer illusion are specific types of visual illusions, not imaginary perceptions without external stimuli.

Question 7

In the Ames room, people appear to grow larger or smaller as they walk from one side of the room to the other because
A)retinal disparity occurs and causes motion parallax.
B)the room illustrates the reversibility of figure-ground objects.
C)accommodation cannot be maintained with movement by the people.
D)the observer's perceptual construction of the room is based on the assumption that the room is square.

Accepted Answer

The Ames room illusion occurs because the observer's perception relies on the assumption that the room is a normal rectangular (square) room, when in fact it is trapezoidal. This distorted room shape manipulates depth cues and creates the illusion of size changes as people move within it.

Question 8

Perceiving objects or events that have no external reality describes
A)hallucinations.
B)stroboscopic movement.
C)figure-ground images.
D)illusions.

Accepted Answer

Hallucinations are perceptions in the absence of external stimuli, meaning they occur without any real object or event causing them. These perceptions can be visual, auditory, or sensory in nature and are experienced as real by the person having them.

Question 9

You are asked to look through an opening into what appears to be an ordinary room that has a small boy standing in the left corner. As the boy walks from the left corner to the right corner, he appears to grow very large. You have just experienced the illusion created by
A)retinal disparity.
B)the Gestalt principle of contiguity.
C)physiological nystagmus.
D)the Ames room.

Accepted Answer

The Ames room illusion involves a specially constructed room that creates a visual distortion. Despite appearing normal when viewed through a peephole with one eye, the room's unique shape (with one corner actually much farther away than the other) makes a person walking from one corner to the other appear to grow or shrink. This is due to the viewer's inability to perceive the room's true depth and shape, leading to the illusion of size change.

Question 10

Perceptual misconstruction occurs when viewing the Ames room because
A)the room appears square when viewed from a certain angle.
B)observers have prior knowledge of the experiment and expect bizarre experiences.
C)retinal disparity occurs and results in the phenomenon known as motion parallax.
D)of the autokinetic effect.

Accepted Answer

The Ames room illusion occurs because the room is constructed in a way that, from a specific viewpoint, it appears to be a normal rectangular room, but it is actually trapezoidal. This tricks the brain into misjudging the size and distance of objects within it.

Question 11

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 characterized by visual hallucinations in individuals who are partially sighted or blind, but it does not imply mental disturbance. Patients can typically distinguish between the hallucinations and reality, indicating they engage in reality testing and do not suffer from a mental illness in the context of these hallucinations.

Question 12

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 checking one's perceptions against additional information to ensure their accuracy.

Question 13

Perceptual construction proceeds in two major ways, which are __________ processing.
A)inductive and intuitive
B)top-down and bottom-up
C)deductive and divergent
D)lateral and vertical

Accepted Answer

Top-down processing involves using contextual information or prior knowledge to interpret sensory information, while bottom-up processing starts with sensory data and builds up to a comprehensive perception.

Question 14

The organization of information starting with low-level features and building into a complete perception is known as
A)perceptual expectancy.
B)top-down processing.
C)bottom-up processing.
D)perceptual habituation.

Accepted Answer

Bottom-up processing is the approach in perceptual system organization where the process starts with the analysis of lower-level features to build up to a complete perception. This method does not begin with a preconceived idea of what is to be perceived but rather builds the perception from the ground up, based on the elements present in the stimulus.

Question 15

Marcus 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 is a psychological process in which an individual distinguishes between the external world and internal thoughts and perceptions, helping to determine what is real. This is particularly important for individuals with conditions like paranoid schizophrenia, where distinguishing between real and hallucinatory experiences is crucial for managing the condition.

Question 16

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 verification.
B)perceptual evaluation.
C)sensation analysis.
D)reality testing.

Accepted Answer

Reality testing involves checking the external world to distinguish between what is real and what is not, such as attempting to touch something that appears unreal to confirm its existence or non-existence.

Question 17

Distorted perceptions of stimuli that actually exist is the definition of
A)hallucinations.
B)psychosis.
C)illusions.
D)delusions.

Accepted Answer

Illusions refer to distorted perceptions of stimuli that are present in the environment, meaning that there is an actual stimulus, but it is perceived incorrectly.

Question 18

Reality testing refers to
A)obtaining additional information to check 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 one's perceptions against external information to confirm their accuracy, distinguishing between what is internally generated and what exists in the external world.

Question 19

Older people who are partially blind but not mentally disturbed may "see" people, animals, building, plants, and other objects appear and disappear in front of their eyes. This rare condition is known as
A)paranoid schizophrenia.
B)Charles Bonnet syndrome.
C)Klinefelter's syndrome.
D)Turner's syndrome.

Accepted Answer

Charles Bonnet syndrome is a condition where visually impaired individuals experience complex visual hallucinations, often without any mental health issues. It typically affects older adults with significant vision loss.

Question 20

Which of the following is a major symptom of psychosis, dementia, epilepsy, migraine headaches, alcohol withdrawal, and drug intoxication and is also 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 common to conditions such as psychosis, dementia, epilepsy, migraine headaches, alcohol withdrawal, and drug intoxication. They represent a clear sign that an individual may have lost touch with reality, as they involve perceiving things that are not present in the external environment.
