What were they thinking? *spoilers*
The part I found hard to believe was other students terrorizing her for a psychology thesis. What were they thinking, they never would have got away with this, even if they had her signature of consent.
First of all, if she had consented, she would know it was an experiment, so the analysis had to be different, you cannot study someone's behaviour in a known test situation as if it was an unknown situation without messing the whole thing up. And they surely couldn't write something like "we just tricked her to sign it without reading it, so she didn't know"!
But even if she had known it was an experiment, they wouldn't be able to use this, because universities, especially psychology departments, have a code of ETHICS and an ethics board to watch over them, and thus would never allow any experiment that could do somebody major harm. The times when psychology could do just anything in experiments are long gone. I know because my brother graduated in psychology and they were not even allowed to test how people would react to a drunk nun in a bar, because it could hurt somebody's religious feelings. It was not even a conservative university, he told me experiments would not be allowed if they could just bring any medium discomfort to anyone.
So putting a former abduction victim in a lone and dark forest hut to scare the sh!t out of her? Don't make me laugh!
