AnAfricanGreyparrot, previously taught to discriminate more than 40 objects by means of vocal labels, has now acquired a limited understanding of abstract class concepts. The subject, Alex, can routinely decode and successfully reply vocally to queries concerning either coloror shape for exemplars which simultaneously incorporate both variables (e.g., colored and shaped keys, wood, and ...
ConsideringAfricangreyparrots'high level ofsocialtolerance, we predicted that (i) they would show a spontaneous tendency to benefit a partner (unilateral condition) and (ii) this tendency may be further enhanced by the possibility for reciprocal actions when alternating the subjects' roles trial by trial (alternating condition).
It describes several studies concerning allospecific vocallearningingreyparrots, and a paradigm for adaptive vocallearningin these birds that is based on a cognitive perspective. Recent research has begun to throw light on how cognitive processes might be involved in directing the acquisition of allospecific vocalizations.

The Pepperberg study highlighted thesociallearningcapabilities ofAfricangreyparrots. Alex was able to mimic human speech patterns and use language to communicate effectively.
