VISUAL REINFORCEMENT IN FIGHTING COCKS
Journal of the Experimental Analysis of Behavior
|January 1, 1964
Summary
Fighting cocks pecked for visual access to other roosters. Visual reinforcers were compared to food and water, with mirrors showing less effectiveness than live rooster visuals.
Area of Science:
- Animal behavior
- Comparative psychology
- Avian studies
Background:
- Reinforcement schedules are crucial for understanding animal motivation.
- Visual stimuli can act as effective reinforcers in certain species.
- The social dynamics and visual perception of fighting cocks (Gallus gallus domesticus) are complex.
Purpose of the Study:
- To investigate the reinforcing properties of visual stimuli in fighting cocks.
- To compare the effectiveness of visual reinforcers (live rooster vs. mirror image) with traditional reinforcers (food, water).
- To analyze response output under a fixed ratio schedule when visual stimuli are contingent upon behavior.
Main Methods:
- Fighting cocks were trained using a fixed ratio reinforcement schedule for a key-pecking response.
- A visual image of another fighting cock served as the primary reinforcer.
- A three-choice, non-reversible option setup was used to compare visual reinforcers (mirror image, live rooster via window) against food and water.
Main Results:
- The key-pecking response was successfully conditioned using the visual image of another fighting cock as reinforcement.
- When compared in a choice situation, the visual presentation of another rooster maintained a higher response output than a mirror presentation.
- Both live rooster visuals and mirror images were compared against food and water, with the mirror showing the lowest maintenance of response output.
Conclusions:
- Visual stimuli, particularly the image of a conspecific, can function as a significant reinforcer for fighting cocks.
- The relative effectiveness of visual reinforcers varies, with direct visual contact with another rooster being more potent than a mirror image.
- These findings contribute to understanding social motivation and visual perception in avian species, highlighting the importance of social interaction as a reinforcer.

01:20Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
01:06Fixed Action Patterns
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
02:39Predator-Prey Interactions
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...
00:49Complementation Tests
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

01:19Veins of Thorax
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
