Abstract:
Five pigeons were trained to discriminate a constant luminance difference when both reinforcer frequency and reinforcer magnitude were varied in an animal analogue of the human discrete-trial yes- no detection task. Variation of relative reinforcer frequency was more effective in biasing detection performance than variation of relative reinforcer duration. Stimulus discriminability was independent of both reinforcer frequency and reinforcer duration.

Timing and Consequences on Behavior
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...
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...
Operant Conditioning
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
