The Alex Studies: Cognitive and Communicative Abilities of Grey Parrots (Paperback)
by Irene M. Pepperberg
Can a parrot understand complex concepts and mean what it says? Twenty years ago Irene Pepperberg set out to discover whether the results of earlier pigeon studies necessarily meant that other birds-particularly parrots like Alex the Grey-were incapable of mastering complex cognitive concepts and the rudiments of referential speech. This scientific, technical book represents the long-awaited synthesis of the studies constituting one of the landmark experiments in modern comparative psychology.
