Organization in memory and behavior.
Reinforcement shapes the whole rhythm of behavior, not just single responses.
01Research in Context
What this study did
Shimp (1976) wrote a theory paper. He asked: what if we look at the whole rhythm of behavior, not just single responses?
He said reinforcement plans should track how acts unfold in time. The pattern itself is the unit.
What they found
The paper did not test people or animals. It argued that the timing of responses is part of the contingency.
In other words, the way behavior is spaced out can be reinforced just like the behavior itself.
How this fits with other research
Cicerone (1976) gave pigeons fixed-interval food. The birds’ pecks lined up with the clock, proving that schedules sculpt temporal shape.
Julià (1982) later showed the same thing with run lengths: birds learned to peck in short or long bursts to match the payoff.
Green et al. (1999) and D (1991999) pushed further. They said timing needs no inner clock—memory traces and neural loops do the job.
Together these studies turn the 1976 idea into data: behavior is a song, not single notes.
Why it matters
When you write a program, think about the beat. Space prompts, breaks, and reinforcers so the learner can fall into a steady groove. A child who gets praise every 30 seconds will pace her work to that rhythm. Watch the pattern first, then adjust the clock.

03Original abstract
SOME COMMON REINFORCEMENT CONTINGENCIES MAKE THE DELIVERY OF A REINFORCER DEPEND ON THE OCCURRENCE OF BEHAVIOR LACKING SIGNIFICANT TEMPORAL STRUCTURE: a reinforcer may be contingent on nearly instantaneous responses such as a pigeon's key peck, a rat's lever press, a human's button press or brief verbal utterance, and so on. Such a reinforcement contingency conforms much more closely to the functionalist tradition in experimental psychology than to the structuralist tradition. Until recently, the functionalist tradition, in the form of a kind of associationism, typified most research on human learning and memory. Recently, however, research on human memory has focused more on structural issues: now the basic unit of analysis often involves an organized temporal pattern of behavior. A focus on the interrelations between the function and structure of behavior identifies a set of independent and dependent variables different from those identified by certain common kinds of "molar" behavioral analyses. In so doing, such a focus redefines some of the significant issues in the experimental analysis of behavior.
