Answer:
trace conditioning
Step-by-step explanation:
Trace conditioning: In psychology, the term trace conditioning was first introduced by Ivan Pavlov, and is defined as a form of classical conditioning which encompasses the process in which the conditioned stimulus or CS and unconditioned stimulus or UCS are being presented or displayed individually after a particular time interval between both of them.
In other words, in trace conditioning, the unconditioned stimulus and the conditioned stimulus are being separated with respect to time through trace interval.
In the question above, John's experience is an example of trace conditioning.
