Teaching verbal behavior to pigeons.

Palya (1985) taught pigeons to act like little speakers. The birds earned food by pecking keys that matched colors, then learned to peck only when a light meant 'name that color'.

Next the team added mand training: a key peck turned on food for three seconds. Finally they tried intraverbals: one color cue had to trigger pecking a different color key.

Most of the 18 birds learned simple tacts. Several figured out mands. A few even showed intraverbal responses. The study proved you can install Skinner's verbal operants in a bird brain.

Meier et al. (2012) took the same three operants to autistic preschoolers. After teaching either mand or tact, three kids instantly showed the untrained operant. The pigeon work laid the groundwork; the child study shows the pattern holds across species.

Busch et al. (2010) also used pigeons, but taught reflexivity instead of verbal operants. Both labs prove birds can handle symbolic tasks, strengthening the animal model for basic ABA principles.

Rapport et al. (1982) showed pigeons can judge their own prior behavior. Palya (1985) extends that idea: the birds now use their own pecks as verbal stimuli, not just as cues for choice.

You now have a clean animal model for verbal behavior. Use it to explain to parents why separate mand and tact lessons can merge. When a child masters 'cookie' as a mand, probe right away for the tact 'cookie' before you run extra trials. The bird data says the linkage is built into the operant class.
