Differences in the effect of Pavlovian contingencies upon behavioral momentum using auditory versus visual stimuli.
Visual cues build stronger behavioral momentum than sounds, so use lights or pictures when you need persistence.
01Research in Context
What this study did
The team worked with pigeons in a three-part schedule. Each part had its own light color or tone.
In one part, pecks produced food. In the other two, pecks produced food only if a special signal was on. The signal itself never gave food.
They then added a distraction: free food while the birds were working. They counted how many pecks kept going.
What they found
When the signal was a light, the birds kept pecking longer during the free-food distraction. When the signal was a tone, the pecking stopped sooner.
Changing the peck-to-food rules did not change this result. Only the light-versus-tone mattered.
How this fits with other research
Costa et al. (2025) later showed that richer food rates, not bigger food pieces, keep adult humans working. Both studies say the same thing: what happens right before food sets the strength of behavior.
Cooper (1997) used the same three-part chain and found that different lights help pigeons tell the parts apart. Duker et al. (1996) now shows those lights also give extra staying power.
Decasper et al. (1977) saw that pigeons like compound light-plus-tone signals. Duker et al. (1996) shows the light half of that compound carries the momentum, not the tone half.
Why it matters
If you want a client to keep working when distractions show up, pair the task with a unique visual cue—a colored card, a light, or a picture. Sounds alone will not give the same staying power. Use visual cues during drills, transitions, or when other kids walk by. Keep the cue consistent and only present when the best payoffs occur.

03Original abstract
We examined the role of Pavlovian and operant relations in behavioral momentum by arranging response-contingent alternative reinforcement in one component of a three-component multiple concurrent schedule with rats. This permitted the simultaneous arranging of different response-reinforcer (operant) and stimulus-reinforcer (Pavlovian) contingencies during three baseline conditions. Auditory or visual stimuli were used as discriminative stimuli within the multiple concurrent schedules. Resistance to change of a target response was assessed during a single session of extinction following each baseline condition. The rate of the target response during baseline varied inversely with the rate of response-contingent reinforcement derived from a concurrent source, regardless of whether the discriminative stimuli were auditory or visual. Resistance to change of the target response, however, did depend on the discriminative-stimulus modality. Resistance to change in the presence of visual stimuli was a positive function of the Pavlovian contingencies, whereas resistance to change was unrelated to either the operant or Pavlovian contingencies when the discriminative stimuli were auditory. Stimulus salience may be a factor in determining the differences in resistance to change across sensory modalities.
