Imitation of a two-action sequence by pigeons

Area of Science:

• Animal behavior
• Comparative psychology
• Cognitive ethology

Background:

• Imitation is often linked to perspective-taking abilities in developmental psychology.
• However, imitative behaviors are observed in animals, questioning this link.
• Previous research showed birds can perform action-level imitation (single responses).

Purpose of the Study:

• To investigate if pigeons can perform program-level imitation (unfamiliar sequences of behaviors).
• To assess the extent of imitation in pigeons for complex behavioral sequences.

Main Methods:

• Pigeons were exposed to a demonstrated two-step behavioral sequence.
• The sequence involved a treadle response followed by a screen-pushing action.
• Behavioral matching of the demonstrated sequence was recorded.

Main Results:

• Pigeons demonstrated a significant tendency to imitate the demonstrated two-step sequence.
• Individual differences in imitation ability were observed.
• The imitation involved matching both the treadle response and the screen-pushing direction.

Conclusions:

• Pigeons are capable of program-level imitation, performing unfamiliar behavioral sequences.
• This finding suggests that complex imitation may not solely rely on perspective-taking abilities.
• The study contributes to understanding the evolution of imitation in non-human animals.
