Classification<unk>  is generally diagnosed through the use of two tests, the Faux Pas Test and the Strange Stories Test. Both of these tests are used to show deficits in theory of mind, the recognition of mental states of others. For people with<unk> , it is mainly the<unk>  states that are difficult for them to recognize. Studies have shown that subjects with amygdala damage perform poorly on both the Faux Pas test and the Strange Stories test. Faux Pas test The Faux Pas test measures how<unk> ly adept one is in certain situations. For this test, a faux pas is considered a statement or action that accidentally offends another person. During the test, the subject or patient is told of various<unk>  situations and later asked if one of the people in the story would be offended in the situation. A person with impaired<unk>  skills would have difficulty in detecting the faux pas made by characters in the stories. Strange Stories test The<unk>  aspect of<unk>  is usually assessed with the Strange Stories test. The subject or patient is presented with two sets of stories:<unk>  stories that refer to people's<unk>  states and physical stories that refer to physical behaviors. Those with deficits in determining others'<unk>  states will answer questions regarding the<unk>  stories incorrectly but will answer questions regarding the physical stories correctly (showing that their comprehension of the stories is not impaired but instead that their comprehension of<unk>  states in others is impaired). Other tests Another test that could be used to diagnose<unk>  deficits is the Facial Recognition Test, where subjects are presented a number of pictures of faces with a variety of expressions, and are asked to determine what emotion they are depicting. Differential diagnosis The constellation of symptoms in<unk>  can also be seen in a number of different behavioral disorders. Autism or Asperger's syndrome Both autism and Asperger's syndrome show deficits in understanding others' mental states, including the recognition of<unk>  expressions. Damage to the amygdala has also been implicated for these disorders, which can explain why the symptoms appear to overlap. Klüver–Bucy syndrome Although rare in humans, Klüver–Bucy syndrome has many symptoms that are strikingly similar to those seen in<unk> . The amygdala and temporal lobes have been implicated in the pathology of Klüver–Bucy syndrome as well, leading to docility, hyperorality, and in some rare cases hypersexuality. Unlike patients of<unk> , people with Klüver–Bucy syndrome also tend to demonstrate visual agnosia (inability to recognize visual stimuli) and have difficulties with visual perception.
