Reduced affect display
Reduced affect displays (better known as emotional blunting) is the condition where a person has a reduced emotional reaction. People with this condition have problems expressing their feelings. They are unble to do this while they talk about certain problems which normally cause people to express emotions. Expressive gestures aren't common. There is also little or no animation in the facial expressions or the changes for certain people's voices. Reduced affect is often the symptom of autism, depression, schizoid personality disorder, schizophrenia or even post-traumatic stress disorder. It is also often the side effect of certain drugs (these tend to include antipsychotic or antidepressant drugs).
