TV programme Scientific American Frontiers has made online video available from a programme on the psychology and neuroscience of hidden motives.
The first segment explores the brain’s reaction to ‘cool’ and ‘uncool’ products, a new field, christened neuromarketing.
Other segments explore the Implicit Association Test, a relatively new technique for measuring unconconsious associations and biases, and an exploration of the neural basis of moral reasoning.
