Understanding Operant Conditioning

In operant conditioning subjects voluntarily operate on their environment in order to produce desired consequences. Any type of reinforcement strengthens a behavior, while any type of punishment weakens a behavior. Remember that positive reinforcement and punishment adds (+) something, while negative subtracts (-) something. In the following chart, identify each box as Positive Reinforcement, Negative Reinforcement, Positive Punishment, or Negative Punishment.Each one will be used only once.

Give something to the organism (+) / Take something away from the organism (–)
Likes (Appetitive)
Dislikes (Aversive)

Once you’ve completed the chart, read the following scenarios and move your finger to the appropriate box based on the information provided.Make sure to consider whether you are strengthening or weakening the behavior. Label each scenario as the PR, NR, PP, or NP. Options may be used more than once.

PR = Positive Reinforcement

NR = Negative Reinforcement

PP = Positive Punishment

NP = Negative Punishment

Reinforcement Schedules

The text indicates that in real life, continuous reinforcement is rare. Sometimes responses are reinforced, sometimes not. Among the most important schedules of partial reinforcement are the fixed ratio (FR), variable ratio (VR), fixed interval (FI), and variable interval (VI). Identify the schedule by writing your answer in the space provided. All four options will be used more than once.

Fixed = it is set

Variable = it changes

Ratio = response (how much?)

Interval = time (when?)

FR = Fixed Ratio

VR = Variable Ratio

FI = Fixed Interval

VI = Variable Interval
