The negative symptoms of schizophrenia are so-named because they are considered to be the loss or absence of normal traits or abilities, and include features such as:

• flat or blunted affect and emotion,
• poverty of speech (alogia),
• anhedonia, and
• lack of motivation (avolition).

Despite the appearance of blunted affect, recent studies indicate that there is often a normal or even heightened level of emotionality in Schizophrenia especially in response to stressful or negative events.^[1]
