In which method is the contingency less rigid?

The choice of Natural Environment Teaching (NET) reflects a less rigid contingency because this method focuses on teaching skills in the context of everyday activities and interactions. In NET, learning occurs in natural settings where the environment is more dynamic and responsive to the learner's interests and motivations. This approach allows for flexibility in how teaching moments are presented, making it easier to incorporate teaching into spontaneous situations rather than relying on a structured format.

Unlike more rigid methods, such as Discrete Trial Training (DTT), where specific trials and prompts are used in a controlled environment, NET emphasizes the importance of using natural cues and reinforcement that are relevant to the learner’s everyday life. This can lead to a more meaningful and engaging learning experience, as it aligns more closely with real-life situations and the individual's preferences.

Behavior Modification and Systematic Instruction, while effective in their respective contexts, often rely on more structured and formalized methods of reinforcement, making them less adaptable than NET. Therefore, NET’s focus on the natural environment and adaptive learning interactions contributes significantly to a less rigid approach to behavioral contingencies.
