The condition that a marketer must not adhere to for modeling as a form of observational learning to occur is "reaction."
1. **Reaction:** This is not a condition that a marketer must adhere to for observational learning to occur. In observational learning, individuals observe the behavior of others and its outcomes, without the necessity of an immediate reaction. The focus is on paying attention, retaining the observed information, and being motivated to imitate the behavior later.
2. **Attention:** This is a critical condition for observational learning to take place. The individual must pay attention to the model's behavior in order to learn from it.
3. **Retention:** After paying attention, the individual must retain the observed information in their memory. If they forget what they saw, they won't be able to replicate the behavior later.
4. **Motivation:** Individuals must be motivated to imitate the behavior they observed. Motivation can come from various sources such as perceived rewards, identification with the model, or personal goals.
Therefore, in the context of observational learning for marketers, the absence of a required immediate reaction sets it apart from the other conditions necessary for modeling to be effective.
