What new methods of analysis have been developed in the age-old struggle to discover if someone is telling the truth...or not? Some scientists have gone beyond the polygraph to model other ways of detecting whether we are getting a straight answer or being led down a crooked path.
Psychology. Neuroscience. Drugs. All can be tools of interrogation. In this episode, an expert shows me how to coerce unsuspecting subjects into signing false confessions; a police psychologist questions me about my personal life after I am injected with a truth serum; and I match wits against a new brainwave-reading lie-detection method developed at Northwestern University.
When examining the adolescent brain we find mystery, complexity, frustration, and inspiration. As the brain begins teeming with hormones, the prefrontal cortex, the center of reasoning and impulse control, is still a work in progress. For the first time, scientists can offer an explanation for what parents already know -- adolescence is a time of roiling emotions, and poor judgment.
In part 2, Prof. Arthur Shapiro takes us through visual illusions that show how our brain processes retinal impressions from light and dark. Watch as things "move" while they are standing still. It will be hard to believe your eyes after watching this program!

In this episode, I take a look at whether those who donate money to charity become more likely to let a kid take the blame for a crime they know they committed.
Professor Shapiro reaches back into history to show that artists, architects and mathematicians have also employed visual “tricks” to baffle and entertain us by manipulating perspective and challenging our ideas of what is real and what is fake.
