Final answer:
The specific parable cited by Van Epp is not mentioned, but he highlights the concept of scripts, which are sequences of behaviors expected in certain social situations, similar to how biblical parables teach moral lessons.
Step-by-step explanation:
The parable used by Van Epp to illustrate how certain situations or contexts prompt common relationship behaviors or scripts is not explicitly mentioned in the materials provided. Scripts, as defined by Schank & Abelson (1977), refer to a person's knowledge about the sequence of events expected in a specific setting. These scripts help guide behavior in various social situations and are an important source of information for understanding social roles and norms. Biblical parables have often been used to illustrate moral or spiritual lessons, which may parallel how scripts in psychology illustrate the role of expected behaviors in given contexts.
