I think this raises an important point: control. The kind of runner we're talking about feels totally in control during their interval sessions or other workouts, but when they get into a race situation, they feel a total lack of control which leads to the fear of "being chased" instead of the exhilaration of "chasing down their opponents". The need for control is possibly a cultural thing, but is important for athletes in this country nevertheless.
How to remedy this? It's hard to say. Most of these overthinking types can't just be told to "stop overanalyzing it", because that's just not in their nature. The cure for this can be different between different people, but, as others have said, probably some combination of relaxation, positive visualization and forcing the runner to start the race slower will build their confidence.
Say what you want about him, but Steve Magness has some good ideas on countering this problem. He says (paraphrasing here) that training is certain, controllable, and knowable. Racing is exactly the opposite of all of that. To get your athletes used to this kind of mental stress, you should introduce uncertainty and unpredictability into workouts occasionally.
So for example, instead of saying at the outset, "we're going to do 6x1k at 5k pace today," you only tell your runners before each repeat (or not even then!) how far the repeat is going to be. Doing uncertain mixed workouts, like a 1k, a 500, a 2k, a 500, a few 200s, another 1k. Abrupt changes of pace within workouts, etc. "Run 5k pace until I blow the whistle." That kind of thing.
I've only used it a very limited number of times, since I don't really have many headcases recently (knock on wood...). I think it could be really easy to outsmart yourself with this stuff and do it too often, or give kids the impression that you're just making it up as you go. But in small doses, could counteract some of the control problems you mention.
