This chapter briefly reviews what is known—and what remains to be understood—about
Grey parrot vocal learning. I review Greys' physical capacities—issues of auditory perception …

During the past 24 years, I have used a modeling technique (M/R procedure) to train Grey
parrots to use an allospecific code (English speech) referentially; I then use the code to test …

Human speech and bird vocalization are complex communicative behaviors with notable
similarities in development and underlying mechanisms [1]. However, there is an important …

Evidence exists for a form of imitation, vocal segmentation, by a Grey parrot. Data show that
the bird understands that his labels are comprised of individual units that can be recombined …

On the basis of primarily behavioral data, researchers (eg, PM Greenfield, 1991) have
argued (a) that parallel development of communicative and physical object (manual) …

The authors present context-dependent evidence for a form of mutual exclusivity during
label learning by Grey parrots (Psittacus erithacus). For human children, mutual exclusivity …

The lingual and laryngeal apparatus are the mobile and active organs within the oral cavity,
which serves as a gateway to the respiratory and alimentary systems in terrestrial …

Grey parrots (Psittacus erithacus) do not acquire referential English labels when tutored with
videotapes (a) in social isolation (IM Pepperberg, 1994);(b) when reward for an attempted …

Grey parrots (Psittacus erithacus) learn referential English labels when they view and
interact with 2 humans who model vocal labeling and who demonstrate referentiality and …

Research into speech perception by nonhuman animals can be crucially informative in
assessing whether specific perceptual phenomena in humans have evolved to decode …
