Variation of reinforcement in performance of a motor skill
Abstract:
A simple experimental procedure administered by parents was used to study the effects of variation of reinforcement on performance of a motor skill by a 7-yr.-old retarded male. Owing to hemiplegia this subject has a very restricted range of movement in his left hand. The task required him to use his left hand to place wooden cubes within squares drawn on a paper sheet. Factors varied were type of reinforcer (3 consumables), schedule (continuous, fixed ratio and variable ratio), and frequency of reinforcement. Administration of variable ratio delivery was proceived as an enjoyable game by the subject who produced his best performances under this condition. Functional analyses (mini-experiments) should include type of reinforcer and form of delivery.

Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
Reinforcement
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:
Primary and Secondary Reinforcers
Effective reinforcers for humans vary depending on the individual and the context. Primary reinforcers, such as food, water, sleep, shelter, and pleasure, have inherent value and satisfy basic biological...
Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
Reinforcement Schedules
Once a behavior is learned,...
