Giving a rat some food in the same half of the cage as the bar experimenters want it to press is an example of shaping.

<h3>What is shaping?</h3>

A conditioning paradigm known as shaping is frequently used to analyze behavior in experiments. Differential reinforcement of subsequent approximations is the technique utilized. B. F.

Methods of Shaping Behavior:

  • Positive reinforcement.
  • Negative reinforcement.
  • Punishment.
  • Extinction.
  • Schedules of reinforcement.
