Name:
Reinforcement vs Punishment (7 pts)   Notice how many ways operant conditioning occurs in our everyday lives.

For each example below identify the type of consequence. Remember, in each case a consequence is something which follows a behavior. Consequences may increase or decrease the likelihood (in the future) of the behavior that they follow. For example:
PR (positive reinforcement) - something good is presented, which encourages the behavior in the future
NR (negative reinforcement) - something bad is removed or avoided, which encourages the occurrance of the behavior.
PP (positive punishment) - something bad is presented, which discourages the behavior in the future.
NP (negative punishment) - something good is removed, which discourages the behavior in the future.

Schedules of Reinforcement - for each example below identify the schedule of reinforcement (6 pts)

Remember: Consequences don't always follow every occurrance of a behavior. Some commom
contingencies or ways of "scheduling" when a reinforcement is available are:
FR (fixed ratio) - the reinforcement is delivered only after a certain fixed number of correct response have occurred
VR (variable ratio) - the reinforcement is delivered only after a variable (unpredictable) number of responses hsve occurred
FI (fixed interval) - reinforcement is delivered after the first response that occurs after a specific interval of time has passed
VI (variable interval) - reinforcement is delivered after the first response occurring after a variable interval of time has passed
