Final answer:
In the scenario with David and Jeff, the two processes being illustrated are extinction, where David's demand is not reinforced, and resurgence, where David escalates his behavior before giving up and performing the task himself.
Step-by-step explanation:
The two processes being illustrated in the example with David and Jeff are extinction and resurgence. Initially, David experiences extinction when his demand for a drink is not met with compliance by Jeff; David's expectation for immediate obedience is not reinforced, which leads to his cussing, screaming, and throwing things. This increase in intensity of behavior suggests an attempt at resurgence, as David tries other behaviors that might lead to the desired outcome. Eventually, when Jeff still does not get the drink, David gives up and gets it himself, indicating that the extinction process is indeed taking place. Thus, the correct answer is option (b) Extinction then resurgence.
