Abnormal Psychology Flashcards
What are the positive symptoms of schizophrenia? (5)
delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior
What are delusions?
false beliefs that are firmly held despite what almost everyone else believes or despite evidence that it is not true
What are the 3 common types of delusions?
1) persecutory (believe they are being followed, tricked or spied on)
2) referential (believe that books/newspapers/etc are specifically directed at them
3) bizarre (outside the range of normal life experiences)
What are the most common type of hallucinations for people with schizophrenia?
Auditory hallucinations, often in the form of demeaning or threatening voices or a running commentary on the person’s thoughts or actions
What is considered by many to be the key feature of schizophrenia?
Disorganized speech - loosening of associations, incoherent speech, unrelated answers or comments, slipping from one topic to another
A person with schizophrenia with a markedly disheveled appearance, clearly inappropriate sexual behavior or unpredictable agitation is referred to as having:
grossly disorganized behavior
Catatonic behavior in schizophrenia refers to:
less movement and less reactivity to the world - more vegetable-like
What is the difference between positive and negative symptoms in schizophrenia?
Positive symptoms = too much of, or a distortion of normal functions
Negative symptoms = too little, restricted range and intensity of emotions or other functions
What are the negative symptoms of schizophrenia? (3)
1) lack of affect - flat affect, reduced body language
2) lack of speech and thoughts - alogia
3) lack of or restricted initiation of goal-directed behavior - avolition
(lack of thoughts, feelings expression, and behavior)
A person with relatively intact cognition and affect but who is preoccupied with one or more delusions (which are usually organized around a coherent theme - often persecutory or grandiose) and/or has frequent auditory hallucinations related to these delusions would be diagnosed with which subtype of Schizophrenia?
Paranoid Type
What are the symptoms of Disorganized Type Schizophrenia?
disorganized speech and behavior, and flat or inappropriate affect. Delusions and hallucinations may or may not be present; if they are, they are usually fragmentary and not organized around a coherent theme
To be diagnosed with Catatonic Type Schizophrenia, a person must demonstrate:
2 of the following symptoms which include
3 motor, 1 speech, 1 speech OR motor
1) too little motor activity - immobility (waxy flexibility or stupor)
2) too much motor activity - excessive
3) strange motor activity - bizarre postures, stereotyped movements
4) no speech - extreme negativism or mutism
5) repeating speech OR movement - echolalia or echopraxia
When is a person diagnosed with Undifferentiated Type Schizophrenia as opposed to Residual Type?
A person is diagnosed with undifferentiated type when their symptoms do not meet criteria for a particular subtype. A person is diagnosed with residual type schizophrenia when the person is not currently experiencing positive symptoms (delusions, hallucinations, disorganized speech, or disorganized behavior) but has had these symptoms in the past and continues to display negative and/or attenuated positive symptoms (eccentric speech, odd beliefs, etc)
What is the difference between Type I and Type II Schizophrenia proposed by Crow?
Type I = positive symptoms.
Positive (good) premorbid functioning,
Positive response to traditional antipsychotics,
believed to be due to neurotransmitter abnormalities.
Type II = negative symptoms.
Negative (poor) premorbid adjustment,
Negative (poor) response to traditional antipsychotics, and more likely due to structural brain abnormalities
