Answer:
This exercise is an example of cognitive complexity.
Explanation:
In psychology, cognitive complexity refers to the ability one has to perceive nuances and meanings in a situation. People with high cognitive complexity are able to think in a more abstract manner, coming up with elaborate interpretations. That is what happens in the example we are studying here. You went from a simple interpretation - my friend is busy - to a much more complex one - my friend is angry at me - even though nothing explicitly happened to lead you to that conclusion.
