Hopefully you've watched the TV show Columbo. Curious about what this character has to do with psychology? You'd be surprised. In this episode I analyze Columbo in terms of the psychological technique called motivational interviewing. I also take a look at the criminal lineup scene in the Jennifer Garner movie, "Peppermint". I also explain why you remember how to ride a bike but can't remember where you put your cell phone. Along the way we learn about Semantic vs. Procedural memory.
