Echophenomenon (also known as echo phenomenon) is "automatic imitative actions without explicit awareness" or pathological repetitions of external stimuli or activities, actions, sounds, or phrases, indicative of an underlying disorder.

The echophenomena include repetition:

  • echolalia – of vocalizations (the most common of the echophenomena)
  • echopraxia – of actions
  • echomimia – of facial expressions
  • echographia – in writing
  • echoplasia – physically or mentally, tracing contours of objects
  • echolalioplasia – involving sign language, described in one individual with Tourette syndrome as of 2012.
