Look up perseverate in Wiktionary, the free dictionary. |
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 syndrome may display a form of perseveration in that they focus on one or a number of narrow interests. This phenomenon can also occur in people with schizophrenia.
Several researchers have tried to connect perseveration with a lack of inhibition; however, this connection could not be found, or was small.[1][2]
