Two differences between ratio and interval performance are well known:(a) Higher rates
occur on ratio schedules, and (b) ratio schedules are unable to maintain responding at low …

Interval schedules of reinforcement maintained pigeons' key‐pecking in six experiments.
Each schedule was specified in terms of mean interval, which determined the maximum rate …

The differences in behavioral effects between interval and ratio reinforcement have been
pointed out by several investigators (1, 6, 9, 15), and reveal themselves most clearly in …

EFFECT OF REINFORCEMENT DURATION Page 1 JOURNAL OF THE EXPERIMENTAL
ANALYSIS OF BEHAVIOR EFFECT OF REINFORCEMENT DURATION ON FIXED-INTERVAL …

On a given variable‐interval schedule, the average obtained rate of reinforcement depends
on the average rate of responding. An expression for this feedback effect is derived from the …

Three groups of rats pressed a lever for milk reinforcers on various simple reinforcement
schedules (one schedule per condition). In Group M, each pair of conditions included a …

In Experiment 1, rats were exposed to progressive‐ratio schedules of food reinforcement
while other rats were exposed simultaneously to yoked‐interval schedules that arranged …

Three pigeons received training on multiple variable‐interval schedules with brief
alternating components, concurrently with a fixed‐interval schedule of food reinforcement on …

Twelve pigeons responded on two keys under concurrent variable‐interval (VI) schedules.
Over several series of conditions, relative and absolute magnitudes of reinforcement were …

Four experiments examined the effects of increasing the number of food pellets given to
hungry rats for a lever‐press response. On a simple variable‐interval 60‐s schedule …
