Definitions:

Partial Reinforcement

A conditioning method where a response is only occasionally rewarded, leading to more resilience in the learned behavior.

Continuous Reinforcement

A learning principle where every instance of a desired behavior is reinforced, leading to rapid acquisition of the behavior.

Immediate Reinforcement

The instant reward following a specific behavior, intended to increase the likelihood of that behavior being repeated.

Punishment

A consequence delivered following an undesired behavior, intended to decrease the likelihood of that behavior occurring in the future.
