Question 1

Experiencing extended periods of immobility is associated with

Accepted Answer

Extended periods of immobility are a characteristic of catatonic schizophrenia, which is a subtype of schizophrenia that is marked by unusual movements or behaviors, including prolonged periods of immobility. Disorganized, paranoid, and undifferentiated schizophrenia are not specifically associated with extended periods of immobility.

Question 2

The belief that one is the Prime Minister of Canada is an example of which schizophrenic symptom?

Accepted Answer

A delusion is a fixed false belief that is not based in reality. Believing one is the Prime Minister of Canada when one is not would be an example of a delusion.

Question 3

Laurie,a 30-year-old homemaker,has delusions and hallucinations,often makes odd or inappropriate gestures,and does not bathe or change her clothes regularly.Her symptoms indicate she is suffering from ______ schizophrenia.

Accepted Answer

Laurie's symptoms suggest that she is displaying disorganized behavior and disorganized thinking, characteristic of disorganized schizophrenia. This includes delusions, hallucinations, and inappropriate behaviors, such as odd gestures and poor hygiene. Catatonic schizophrenia is marked by motor disturbances and a lack of movement, which are not present in Laurie's case. Residual schizophrenia is characterized by milder symptoms after an acute episode, and paranoid schizophrenia is marked by delusions of persecution or conspiracy. Therefore, disorganized schizophrenia is the best fit for Laurie's symptoms.

Question 4

Isaiah has recently started experiencing hallucinations and delusions and doesn't seem to be able to organize his thoughts or behaviours.It seems as though Isaiah may be entering the _________ phase of schizophrenia.

Accepted Answer

The active phase of schizophrenia is marked by the emergence of positive symptoms such as hallucinations and delusions, and disorganized thoughts and behaviors. The prodromal phase precedes the onset of symptoms, the negative phase is characterized by a lack of motivation and emotion, and the residual phase involves a return to a relatively stable state after the active phase.

Question 5

Research into the genetic influence on the development of depression has found that:

Accepted Answer

Research has found that individuals who inherit two copies of the short (serotonin transporter) gene are at a greater risk to develop depression. This gene is involved in the transportation of serotonin, a chemical in the brain that regulates mood, and having two copies of the short gene can result in reduced serotonin levels, which may contribute to the development of depression. Individuals who inherit two copies of the long gene are not necessarily protected from depression, but they may have a lower risk compared to those with two copies of the short gene. Inheriting one copy of each gene does not necessarily protect against or increase the risk of depression.

Question 6

Which of the following statements is TRUE regarding suicide?

Accepted Answer

Men are significantly more likely to die by suicide than women, with statistics often showing that men die by suicide at a rate approximately four times higher than that of women. This is attributed to various factors including differences in methods used, societal expectations, and willingness to seek help.

Question 7

While doing volunteer work at a mental hospital,Mary is put on a ward for adults with severe mental disorders.One patient remains in the same position for hours at a time and never talks.The doctors tell Mary this patient suffers from

Accepted Answer

The patient's behavior of remaining in the same position for hours at a time and not talking is characteristic of catatonic schizophrenia, which is marked by extreme disturbances in movement and behavior. Residual schizophrenia is characterized by a lack of prominent positive symptoms, disorganized schizophrenia is characterized by disorganized speech and behavior, and paranoid schizophrenia is characterized by delusions and auditory hallucinations.

Question 8

Feeling insects crawling on your skin (when there are none)or hearing voices (when no one is talking)would be examples of what symptom of schizophrenia?

Accepted Answer

Hearing voices or feeling sensations of insects crawling on your skin, when no one or nothing is present, are examples of hallucinations, which are commonly experienced by individuals with schizophrenia. Delusions are false beliefs that are not based in reality, and compulsions and obsessions are associated with obsessive-compulsive disorder.

Question 9

Gigi,who has been diagnosed with schizophrenia,believes that she was sent by God to one day rule the world.Her belief is an example of a(n)

Accepted Answer

Gigi's belief that she was sent by God to rule the world is a delusion, which is a strongly held belief that is not based in reality and is not consistent with the person's cultural or religious background. Delusions are a common symptom of schizophrenia.

Question 10

False sensory perceptions that often take the form of hearing voices are called

Accepted Answer

Hallucinations are false sensory perceptions that can occur in any sensory modality, but often take the form of hearing voices. Delusions are false beliefs that are not based in reality, while obsessions and compulsions are symptoms of obsessive-compulsive disorder and involve intrusive and repetitive thoughts or behaviors.

Question 11

The _________ model explains how inheritance of short or long copies of the serotonin transporter gene and socioeconomic status might interact to influence the risk of developing depression.

Accepted Answer

The diathesis-stress model proposes that psychological disorders arise from the interaction between a person's genetic vulnerability (diathesis) and stressors in the environment. In this case, the short or long copies of the serotonin transporter gene represent the diathesis, while socioeconomic status represents the environmental stressor.

Question 12

The rate of schizophrenia in the general population is

Accepted Answer

The rate of schizophrenia in the general population is generally reported to be less than 1%. While rates may vary slightly depending on the source, there is consensus that schizophrenia is a relatively rare disorder.

Question 13

False beliefs held by a person who has no evidence to support such beliefs are known as

Accepted Answer

Delusions are false beliefs held by a person who has no evidence to support such beliefs. Hallucinations refer to perceptions that occur without any external stimuli. Obsessions are repetitive, unwanted and intrusive thoughts, while compulsions are repetitive behaviors aimed at reducing anxiety.

Question 14

For young individuals,the risk for suicide increases when they are

Accepted Answer

Studies have shown that young individuals who are victims of bullying are at a higher risk for suicide. Being bullied can result in feelings of hopelessness, worthlessness, and isolation, which can contribute to depression and suicidal thoughts. Factors such as gender and family income are not consistently linked to increased suicide risk in young people. The transition from elementary to middle school can be a challenging time, but it is not necessarily a significant risk factor for suicide on its own.

Question 15

A patient in a psychiatric hospital exhibits disordered thinking,bizarre behaviour,and hallucinations.This person is probably suffering from

Accepted Answer

Disordered thinking, bizarre behavior, and hallucinations are all symptoms of schizophrenia. Bipolar disorder includes symptoms of mood swings and major depression includes symptoms of persistent feelings of sadness and hopelessness. Dissociative disorders include symptoms of a disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity.

Question 16

Zach has started withdrawing from his family and friends,has lost interest in others,and is having trouble organizing his thoughts.He has not experienced any hallucinations or delusions.Zach is most likely in the ________ phase of schizophrenia.

Accepted Answer

Zach's symptoms of withdrawing from others, losing interest, and having trouble organizing his thoughts suggest that he is in the prodromal phase of schizophrenia. This phase is characterized by mild symptoms that precede the onset of full-blown psychotic episodes. Zach has not experienced hallucinations or delusions, which are characteristic of the active phase of schizophrenia. The negative and residual phases are later phases of the disorder that occur after the active phase.

Question 17

The interaction between genetic predisposition and environmental effects is known as the

Accepted Answer

The diathesis-stress model refers to the interaction between genetic predisposition (diathesis) and environmental effects (stress). It suggests that mental disorders are the result of a combination of genetic vulnerability and stressful life events or circumstances. This model is widely used in the field of psychology to explain the development of mental disorders.

Question 18

Most individuals with schizophrenia experience three distinct phases of the disorder:

Accepted Answer

The three phases of schizophrenia are commonly referred to as prodromal, active, and residual. The prodromal phase is characterized by mild symptoms and changes in behavior or mood that precede the onset of full-blown symptoms. The active phase is when the most severe symptoms of schizophrenia, such as hallucinations and delusions, are present. The residual phase is when symptoms are no longer as severe as the active phase, but some impairment in functioning remains.

Question 19

Which neurotransmitters appear to be most important in the development of depression?

Accepted Answer

Research has implicated dysregulation of the neurotransmitters dopamine, serotonin, and norepinephrine in the development of depression. Dysfunction in the availability or binding of these neurotransmitters can disrupt mood regulation and lead to depressive symptoms.

Question 20
