Conduit dapproche

Conduit d’approche

Conduit d’approche, or "homing-in" behavior, is a verbal output phenomenon applied to patients with conduction aphasia attempting to repeat a target word, in which multiple phonemic approximations of the word are presented, with gradual improvement until the target word is achieved. This phenomenon suggests that an acoustic image of the target word is preserved in this condition. A similar phenomenon may be observed in patients with optic aphasia attempting to name a visual stimulus.

A similar behavior is seen in so-called speech apraxia, in which patients repeatedly approximate to the desired output before reaching it.
