Birdsong and speech acquisition
|
| |
Utrecht, Netherlands (Nature): Song learning in songbirds has strong similarities with speech acquisition in human infants. Songbirds need to learn their songs from an adult conspecific. This occurs in two phases: a memorization phase, early in life, during which the young bird forms a neural representation (a 'template') of the song of a tutor; and a sensorimotor phase, during which the bird's own vocal output is matched to the stored template.
