Final answer:
Watching a child swing a bat exemplifies modeling, where an individual learns by observing and imitating others, particularly through the steps of attention, retention, reproduction, and motivation in the observational learning process.
Step-by-step explanation:
Having a child watch you swing a bat would be an example of B) Modeling. Modeling is a form of social learning where an individual acquires new behaviors by observing and imitating others. It is part of the observational learning process as described by Albert Bandura. The steps involved in the process of modeling require that the individual pay attention, retain the observed behavior, have the ability to reproduce the behavior, and be motivated to do so. This is how children can learn a wide range of behaviors, from simple actions to complex skills, by watching their parents, siblings, or peers.
