"One in Four" has been a prominent slogan in campaigns to reduce stigma and discrimination against people with mental health problems. But Clinical Psychologist Martin Seager tells Claudia Hammond why he believes saying 'one in four' people will experience mental illness in any one year actually increases prejudice, artificially separating our mental health from our physical health. The Director of Time to Change, Sue Baker, disagrees, and argues that this statistical campaign tool has helped to normalise mental illness and played an important part in changing public attitudes.

Humans vary in their ability to "keep a cool head" in emotionally charged situations, and difficulty to regulating emotions is linked to many psychiatric disorders. Dr Tim Dalgliesh from the Medical Research Council's Cognition and Brain Sciences Unit at the University of Cambridge tells Claudia about new research which suggests our brains could, with practice, be trained to focus on the goal at hand, and not get diverted by overwhelming emotions.

TV dramas, plays and films can be ruined when scriptwriters get the science wrong. The Wellcome Trust's first ever screenwriting fellowship is an attempt to give film makers the chance to immerse themselves in science and explore their interests with the country's top scientific brains. Award winning film maker Clio Barnard (The Arbor and The Selfish Giant) has spent a year trawling the Wellcome archives and meeting psychologists, psychiatrists and neuroscientists investigating memory, perception, hallucination and the impact of trauma: all themes which recur in her movies.

Producer: Fiona Hill.

Claudia explores pioneering new research into radicalisation. She talks to Professor Kamaldeep Bhui who is doing research to try and prevent radicalisation in the early stages. His idea is, if we can understand what makes someone sympathetic to violence and terrorist actions then radicalisation can be stopped before it starts. He explains why vulnerability to radicalisation is linked to depression. Also in the programme, 50 years after a murder which spawned a whole new area of psychology. Did 38 people really watch the murder of Kitty Genovese and no one call the Police or help her? Claudia talks to author, Kevin Cook and psychologist, Rachel Manning about the misreporting of the case yet its continuing legacy for psychology in understanding why people do or don't help others. Claudia talks to James Withey, creator of the Recovery Letters, a website of letters from people who have been depressed to help those who are now.
