With the lucid verve and solid scientific grounding of an Oliver Sacks or Malcolm Gladwell, Dr. Brian Boxer Wachler guides listeners on a fascinating tour of the bedrock of our existence—the way our senses perceive everything and everyone in the world around us.

Why does one person see Jesus in a shower curtain, get a “bad feeling” about someone they’ve just met, or hear a conversation so differently than the other person? Boxer Wachler describes some of the mysterious medical conditions that cause nonpsychiatric hallucinations and neurological mix-ups, then focuses on how we all receive and interpret the messages of our senses. Practical as well as provocative, Perceptual Intelligence also offers listeners ways to improve their PI, “reality check” their perceptions, and make desired changes in their lives.
