Final answer:
Feedback shown to observers regarding a model's actions is essential for observational learning, as it motivates learners to replicate behaviors, according to Albert Bandura's social learning theory.
Step-by-step explanation:
The statement that is true about learning models is that their feedback should be shown for the observers to learn. According to Albert Bandura's social learning theory, which includes observational learning, the consequences of a model's actions (i.e., feedback) have an impact on an observer's motivation to learn and replicate the behavior. Observational learning is not a mere process of imitation, but a complex cognitive process where attention, retention, reproduction, and motivation are necessary steps for learning to occur effectively. Bandura introduced the concepts of vicarious reinforcement and vicarious punishment, suggesting that seeing a model being rewarded or punished influences the likelihood of an observer replicating the model's behavior.
