VISUAL REINFORCEMENT IN FIGHTING COCKS.

The researcher put fighting cocks on a fixed-ratio schedule. The birds had to peck a key to see a picture.

The picture was either a live video of another rooster or a mirror image of themselves. The team counted how fast each bird pecked.

Both pictures kept the pecking going, but the live rooster video won. Birds pecked faster for the live image than for their own mirror image.

This shows that social sights can act like candy for birds.

THOMPSON et al. (1965) ran the same idea with Siamese fighting fish. They swapped color instead of live vs mirror and still saw pecking (or in this case, swimming) change.

McGee et al. (1983) showed rats only approach visual cues, not sounds. The cock study adds that even within visuals, live social cues beat self-images.

Van Hemel (1973) proved pigeons peck hardest when a colored key predicts food. Our 1964 cock paper widens the menu: social pictures can also keep the ratio running.

You now know that social images can reinforce operant behavior, but live or dynamic ones work best. When you design token boards, video rewards, or peer modeling programs, pick real faces over static self-portraits. Try short video clips of classmates giving thumbs-up instead of still photos and watch response rates climb.
