Analogical reasoning in amazons

Area of Science:

• Comparative cognition
• Animal behavior
• Avian intelligence

Background:

• Matching-to-sample tasks are used to assess cognitive abilities in animals.
• Previous research has shown identity matching in parrots, but less is known about their relational understanding.

Purpose of the Study:

• To investigate whether orange-winged amazons can perform relational matching-to-sample (RMTS).
• To determine if parrots can exhibit abstract cognitive behaviors similar to other intelligent species.

Main Methods:

• Two juvenile parrots were trained on identity matching-to-sample tasks (color, shape, number).
• Parrots were tested for transfer of learning to novel stimuli and untrained categories (size).
• A critical testing phase assessed relational matching-to-sample behavior without physical matches.

Main Results:

• Parrots successfully transferred learning to new stimuli and the untrained category of size.
• Both parrots demonstrated reliable relational matching-to-sample behavior.
• This higher-order relational responding was spontaneous and not previously trained.

Conclusions:

• Orange-winged amazons possess abstract cognitive abilities, including relational matching-to-sample.
• Parrots exhibit complex cognitive behaviors comparable to those seen in apes and crows.
• These findings expand our understanding of avian intelligence and abstract thought.
