What type of model is demonstrated when learning to purchase a soda by observing someone else first?

When someone learns to purchase a soda by observing another person, this situation exemplifies an unplanned model. In this context, unplanned modeling occurs when an individual learns from watching others in everyday situations without any formal instruction or deliberate intent to teach. This type of learning is often spontaneous and highlights the natural way people acquire skills through observation in their environment.

In the scenario of watching someone buy a soda, the observer picks up cues and strategies simply by witnessing the act, rather than being explicitly taught the steps involved. This aligns with social learning theory, which emphasizes the role of observational learning as a means to acquire new behaviors or skills.

On the other hand, the other types of modeling suggest a more structured or intentional approach. Intentional models would imply a purposeful demonstration intended for teaching, guided models involve direct assistance and feedback from a facilitator, while verbal models rely heavily on spoken instructions or explanations. Since the situation described does not include these elements, it reinforces that the correct answer is indeed the unplanned model.
