Preferences among stimulus matches in the pigeon
Journal of the Experimental Analysis of Behavior
|September 1, 1982
Summary
Pigeons trained on a key-pecking task demonstrated a preference for specific visual stimuli. Even when multiple options were available, birds consistently selected their preferred stimulus match.
Area of Science:
- Behavioral neuroscience
- Animal cognition
Background:
- Investigating stimulus control in avian subjects.
- Understanding associative learning and stimulus preference in pigeons.
Purpose of the Study:
- To examine pigeons' stimulus control and preference in a multi-key operant conditioning task.
- To determine if pigeons develop consistent preferences for specific stimulus matches.
Main Methods:
- Pigeons were trained to peck illuminated response keys.
- A peck changed the stimulus, and a stimulus match illuminated a reward key.
- Reinforcement (grain access) was contingent on pecking the reward key after a stimulus match.
Main Results:
- Pigeons consistently pecked a specific stimulus match, even when multiple stimuli were present.
- Preference for a particular stimulus match ranged from 60% to 100% across trials.
- The task involved up to 12 different stimuli.
Conclusions:
- Pigeons exhibit strong stimulus control and preference in operant conditioning paradigms.
- Individual stimulus preferences can be reliably measured in pigeons.
- These findings contribute to understanding the mechanisms of choice and learning in birds.
