Negative symptoms Most commonly refers to a group of symptoms characteristic of schizophrenia that include loss of fluency and spontaneity of verbal expression, impaired ability to focus or sustain attention on a particular task, difficulty in initiating or following through on tasks, impaired ability to experience pleasure to form emotional attachment to others, and blunted affect.
RELATED TERMS--------------------------------------
Schizophrenia
Any of a group of psychotic disorders usually characterized by withdrawal from reality, illogical patterns of thinking, delusions, and hallucinations, and accompanied in varying degrees by other emotional, behavioral, or intellectual disturbances. Schizophrenia is associated with dopamine imbalances in the brain and defects of the frontal lobe and is caused by genetic, other biological, and psychosocial factors. It is mainly treated by antipsychotic drugs which block Dopamine receptors such as Haloperidol.
Fluency
Able to express oneself readily and effortlessly: a fluent speaker; fluent in three languages.
Attention

Affect
This word is used to described observable behavior that represents the expression of a subjectively experienced feeling state (emotion). Common examples of affect are sadness, fear, joy, and anger. The normal range of expressed affect varies considerably between different cultures and even within the same culture. Types of affect include: euthymic, irritable, constricted; blunted; flat; inappropriate, and labile.
