Shaping Technique Explained

The scenario describes a teacher working with Kiran, a student initially unwilling to follow instructions. The teacher uses patience and rewards small actions that show willingness, gradually guiding Kiran towards enthusiastic participation. This step-by-step process of reinforcing behaviors that get progressively closer to the desired outcome is known as Shaping.

Understanding Shaping in Psychology

Shaping is a fundamental principle in behavioral psychology, particularly within operant conditioning. It involves reinforcing successive approximations of a target behavior. Instead of waiting for the complete desired behavior to occur, the teacher reinforces any small step in the right direction. As the student masters each step, the criteria for reinforcement are increased, leading the student closer to the final goal.

In Kiran's case:

• Initial behavior: Reluctance, not following instructions.
• Teacher's action: Praises/rewards any small sign of willingness (e.g., looking at the teacher, sitting quietly for a moment).
• Progression: As Kiran responds, the teacher reinforces slightly more effortful behaviors (e.g., attempting an instruction, participating partially).
• Goal: Enthusiastic participation.

This method builds confidence and motivates the student by rewarding incremental progress, making the learning process manageable and positive.

Why Other Options Are Incorrect

Let's look at why the other techniques mentioned are not what the teacher used:

• Discrimination: This technique involves teaching the difference between two or more stimuli. For example, learning to respond only when a specific signal is given, and not to other similar signals. The teacher wasn't teaching Kiran to differentiate between signals, but rather to build a specific behavior.
• Chaining: This technique involves breaking down a complex task into smaller, sequential steps and teaching them in order. Each step acts as a cue for the next. For instance, teaching a sequence like washing hands involves multiple steps performed in order. The scenario focuses on modifying a single behavioral tendency (participation), not linking a sequence of actions.
• Generalisation: This occurs when a learned behavior is performed in response to a stimulus similar to the one present during learning. For example, if Kiran learned to participate enthusiastically for this specific teacher, generalisation would be showing that same enthusiasm for instructions from a different teacher. The scenario focuses on the initial learning/modification process, not the transfer of behavior to new contexts.

Therefore, the teacher's method of rewarding small steps towards enthusiastic participation clearly aligns with the definition of Shaping.
