- Perseveration
Perseveration is the uncontrollable repetition of a particular response, such as a word, phrase, or gesture, despite the absence or cessation of a stimulus, usually caused by brain injury or other organic disorder.
If an issue has been fully explored and discussed to a point of resolution it is not uncommon for something to trigger the re-investigation of the matter. This can happen at any time during a conversation. This is particularly true with those who have had traumatic brain injuries.
Those with
Asperger's syndrome also display a form of perseveration in that they focus on one or a number of narrow interests. A person with Asperger's might go to a department store repeatedly to look at air conditioners.Several researchers have tried to connect perseveration with a lack of
inhibition ; however, this connection could not be found, or was small.
