For weeks, you've watched the Jodi Arias saga dramatically unfold on HLN. Arias is on trial for the 2008 death of her ex-boyfriend Travis Alexander -- a killing she claims was pure self defense but that prosecutors call premeditated, cold-blooded murder. Since the trial began weeks ago in Phoenix, Arias has been on a roller coaster of emotions. We've watched as she's cried, described her sexual encounters with Alexander and even made playful comments.

Last week, the jury fired more than 200 questions at Arias on the stand. The questions ran the gamut from why she stayed with Alexander if he was abusive, to the events leading up to his death. It gives us a better idea of what the jury is thinking, but what about Arias' mentality? She appeared to be calm on the stand, but was she really?

To help us break down what Arias is thinking, we spoke to Dr. Daniela Schreier, a clinical psychologist with a specialty in forensics. Dr. Schreier analyzes Arias' state of mind and what her interaction with the jury means.

Next Wednesday, Jodi Arias will return to the witness stand for her 18th day of testimony as prosecutor Juan Martinez will continue to question her about her answers to the jurors’ questions. Don’t miss a minute of the courtroom testimony with live coverage of the Jodi Arias trial on HLN.
