Abnormal Psychology: Chapter 4 Schizophrenia Flashcards
A psychotic mental disorder marked by serious impairments in basic psychological functions–attention, perception, thought, emotion, and behavior.
schizophrenia
Symptoms associated with schizophrenia, involving distorted or excess behaviors, such as hallucinations, delusions, bizarre behavior, confused thinking, and disorganized speech.
positive symptoms
Symptoms associated with schizophrenia, involving a diminution, absence, or loss of normal psychological functions; examples include apathy, flat emotions, lack of self-help skills, and social withdrawal.
negative symptoms
Symptoms involving disturbances in the way thinking is organized
formal thought disorder
A dimension of disordered behavior ranging from immobility (where a person may maintain awkward body positions for hours at a time, appearing stuporous) to great excitement, extreme motor activity, repetitive gestures or mannerisms, and undirected violent behaviors.
catatonia
Loss of the ability to enjoy activities central to a person’s life.
anhedonia
Blunted emotionality, often consisting of minimal eye contact, an emotionless face, little or no tone in the voice, and a drab or listless demeanor.
flat affect
A negative symptom of schizophrenia involving the failure to say much, if anything, in response to questions or comments.
alogia
A mental disorder in which the main symptom is the presence of at least one systematic delusional belief
delusional disorder
The sudden onset of psychotic symptoms marked by intense emotional turmoil and confusion.
brief psychotics disorder
Beginning of a disorder shortly after giving birth.
postpartum onset
A disorder in which people experience symptom of schizophrenia for only a few months.
schizophreniform disorder
A mental disorder in which the person displays symptoms of both schizophrenia and a mood disorder without satisfying the full criteria for either diagnosis.
schizoaffective disorder
A mental disorder in which a person experiences psychotic symptoms beyond what is expected from intoxication or withdrawal from a substance, and in which the person is not aware that the substance is producing the psychotic symptoms.
substance/medication-induced psychotic disorder
The time period before the prodrome, in which it is possible to identify delays in early neurodevelopment (e.g, not meeting key pediatric milestones) that may suggest an increased risk of developing schizophrenia in the future.
premorbid phase
The usual first phase of schizophrenia in which there is an insidious onset of problems, suggesting psychological deterioration.
prodromal phase
The stage of schizophrenia during which one or more psychotic symptoms, such as delusions or hallucinations, appear.
active phase (of schizophrenia)
A stage of schizophrenia during which most psychotic symptoms have subsided in frequency and intensity; the affected person may still be withdrawn and at times, and continue to show social and occupational impairments.
residual phase (of schizophrenia)
the risk of individuals developing a disorder over their lifetime.
morbidity risk
A model that explains how a mental disorder can result from the interaction of a predisposition (diathesis) for a disorder with a trigger (stressor) that converts the predisposition into the actual disorder.
diathesis-stress model
The finding that a greater proportion of people with schizophrenia are born in the winter or early spring months, when, in utero, they would presumably have been more likely to be exposed to viral infections that could affect brain development.
season-of-birth effect
A cavity in the center of the brain that is filled with cerebrospinal fluid.
ventricle
The area of the cerebral cortex that controls executive functions, such as planning and carrying out goal-directed activities.
frontal lobe
A key structure in the forebrain that receives, analyzes, and sends on information from all the sense except smell
