From the thread title I was going to say “Post Traumatic Stress Disorder” but your example indicates something less survival-related. PTSD is normally associated with physically threatening or scary experiences. Fight or flight type of stuff. With PTSD we’re talking fear, a function of your back brain, which has various parts that do different things. As I understand it, these responses happen in two places, the amygdala (fear) and the hippocampus (memory formation). PTSD is more about a trigger, so in this example it might apply if any images, sounds, or other sensory or symbolic reminders of an amusement park caused renewed feelings of fear, which in turn motivated aversive behavior (avoidance). Fear or anxiety also has physiological responses, like knots in the stomach and rapid heartbeat, etc. Memories formed under duress, or emotional excitation, are much stronger, deeper, and more likely to re-program unconscious behaviors than those formed in calm situations.
The above musing is maybe off topic from the question… however, the only way I’d feel crushed by a hot date trashing my taste in entertainment would ultimately be fear-based. Fear or abandonment, really. And both those responses tie into negative emotions related to feelings of being humiliated or abandoned. Both these feelings are social-related, not directly related to survival. I could see it happening if I really, REALLY liked the person, and was already feeling fluttered (a form of fear, excitement, anxiety, uncertainty) and then they did that. In the social realm, humiliation or loss of status = death, because as a social animal if you are ostracized from your band, shunned from the herd, cast out into the wilderness, your chances of survival are slim.
Another example could be an audition where you really wanted that part, had tons of stage fright, and the audition team booed you, mocked you, humiliated you in front of a large crowd of people. Awful. It takes a lot of determination to keep going back and auditioning for other parts after that. But that’s what you have to do. For the amusement parks, same thing. You have to determine that one jerky remark is not going to take your fun away and then go back with a trusted friend, have a great time, and over-write that bad memory with a better one that you make yourself.
Sorry if this is a tangent, or off topic, or wasn’t your question.
