In a research students who were explicitly told that a young woman had been instructed to act in a very unfriendly way for the purposes of the experiment concluded that her behavior reflected _, indicating that they were _ to the fundamental attribution error. Please choose the correct answer from the following choices:
her personality; not susceptible
the situation; susceptible
the situation; not susceptible
her personality; susceptible

The fundamental attribution error occurs when an individual is judged by how she/he acts. It's a tendency to believe that behavior reflects the personality of a person.

Now, in the example, we have a young woman who has been instructed to act in a very unfriendly way. If she had been asked to act in such a way, probably means that it's not natural for her to do so. Therefore, we can assume that she isn't unfriendly and that she is only acting given that she is involved in an experiment.

If the students knew this was an experiment, as they had been told that the young woman had been instructed to act in such a way, they couldn't have been susceptible to the fundamental attribution error because they knew it was an act. And, as it was acting, it's impossible that it could reflect her personality.
