Batman diagnoses Arnold Wesker (AKA The Ventriloquist) as having Multiple Personality Disorder or Dissociative Identity Disorder. But is this diagnois accurate? And is Batman qualified to make this diagnosis, to begin with? In this episode, Dr. Andrea Letamendi breaks down this controversial disorder and tells us what she thinks of Batman's assessment.

This week, we get a clear portrayal of a full-fledged delusional disorder in a new villain: Maxie Zeus. We discuss the diagnosis of Delusional Disorder, types of delusions and the impact the illness could have on the family members, partners and colleagues around the person suffering. Finally, we consider what the real differences are between Batman and Maxie Zeus--could they actually be more alike based on their fixed values, impervious beliefs, and the "creation" of an identity?

What separates humans from robots? Dr. Andrea Letamendi dives into the psychology at play in this fantastic episode that brings up deep emotional themes seen in science fiction classics like Blade Runner and haunting imagery from others like The Terminator.

When we left our heroes, Ra's al Ghul was holding his own daughter above his head, ready to kill her in a sudden fit of insanity, brought on by the rejuvinating effects of the Lazarus Pit. In this episode, we look at the similarities between Batman and Ra's al Ghul, as well as whether Batman would ever be able to have a romantic relationship in addition to the life he leads as Gotham's number one crimefighter. That and more here!

It's our first real look at the mysterious Ra's al Ghul, "The Demon's Head!" First introduced, along with his daughter, Talia, in "Off Balance," this quintessential member of Batman's Rogues really gets to shine in "The Demon's Quest, Part 1."  When Robin and Talia are kidnapped on the same day, Ra's recruits Batman to help him rescue them. But is everything ever as it seems in Gotham City? Their journey takes them from Gotham to Calcutta to Malaysia to the Himalayas and, finally, to the infamous Lazarus Pit! But why? Find out in this week's episode of The Arkham Sessions!

In this episode of the Arkham Sessions, we discuss Batman's inflexible personality, his insistence on working "impaired," and his ability to work with the new deficit of blindness.  We explain potential circumstances in which one could "see without seeing," such as the condition called "blindsight" and the fascinating phenomenon called "neuroplasticity" -- how the brain can adapt and change based on experiences. For instance, if one sense is deprived of input, other senses (hearing, taste, touch) are augmented, and actually take up more "brain space" than initially reserved for those senses! Finally, we revisit the Milgram Obedience Study, a famously groundbreaking study that revealed the dangers of authority and conformity.

Commissioner Gordon has been arrested on suspicion of taking bribes from mob boss Rupert Thorne and Batman's on the case. But so is Gordon's daughter, Barbara, who's showing herself to be quite the accomplished crime fighter herself...as Batgirl! This week, The Arkham Sessions breaks down her acceptance into the Bat Family, how her origin is different than that of Batman and Robin's and whether being a murderer means you're mentally ill!

Brian's love of magic is rewarded with this episode of The Arkham Sessions! Zatanna, the daughter of one of Bruce's old mentors, has come to Gotham to put on a show. Boy, does she ever! But it might get her into trouble. Dr. Letamendi discusses the Batman's continuing saga with unobtainable love interests, the psychology of magic and we even learn how Zatanna's big trick could have been done!
