Eccentric stimuli on multiple fixed-interval schedules
Journal of the Experimental Analysis of Behavior
|March 1, 1975
Abstract:
The effects of presenting a different ("eccentric") stimulus for one interval during either or both components of a cyclic multiple fixed-interval fixed-interval schedule, with 12 short and four long intervals per cycle, were studied in three experiments. Eccentric stimuli in the short-interval component reliably produced a persistent, substantial elevation in key-peck rate. The effect appears to depend on schedule context and an initial "disinhibiting" effect of the eccentric stimulus.

01:24Reinforcement Schedules
Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.

01:22Muscle Stimulation Frequency
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
