response strength
the speed, intensity, or persistence with which responses occur
the speed, intensity, or persistence with which responses occur
response strength
What are the problems with using response rate as response strength?
- response rate is not always correlated with resistance to extinction
- response rate itself is a conditionable aspect of behavior
Nevin’s approach to measuring response strength
examined frequency of reinforcement
mag of reinforcement
delay of reinforcement
and contingency on response rate at the time of reinforcement
examined frequency of reinforcement, mag of reinforcement, delay of reinforcement, and contingencies on response rates at time of reinforcement
Nevin’s approach to measuring response strength ???
multiple schedules
SD with responding switch to different SD with different responding
SD with responding switch to different SD with different responding
multiple schedules
advantages of multiple schedules
each stimulus change produces an immediate, reliable, and clear change in responding
Experiment 1
Baseline Procedure: average responding was higher when the key light was green (VI 1 min) than when it was red (VI 3 min)
Response-Independent food delivery
Findings: high rate of reinforcement (VI 1 min) is more resistant to response-independent food delivery than behavior by a low rate of reinforcement (VI 3 min)
Experiment 2
Baseline: two key lights, green (VI 2 min) and red (VI 6 min), changed to extinction
Extinction
Findings: high rate of reinforcement (VI 2 min) is more resistant to extinction than low rate (VI 6 min)
Experiment 3
Baseline: difference in magnitude (VI 1 min, 2.5s SR; VI 1 min, 7.5s SR)
Response-independent food delivery
Findings: high mag of reinforcement is more resistant to response independent food delivery than low mag of reinforcement
Experiment 4
Baseline: delay of reinforcement (VI 1 min, 1s delay reinforcer; VI 1 min, 9s delay reinforcer)
Delay of reinforcement and Extinction
Findings: short delay to reinforcement is more resistant to response-independent food delivery and extinction than long delay to reinforcement
Experiment 5
Baseline: VI-DRH 1 min, VI-DRL 1 min; high vs low and extinction
response independent food delivery and extinction
Findings: low rate is more resistant to response independent food delivery and extinction than by a high rate of responding
Best method for measuring response strength?
using multiple schedules
using a disruptor (extinction, response-independent food)
comparing response rates from baseline with response rates when the disruptor was presented
