In the BBC's All in the Mind, Claudia Hammond and guests delve deeper into the potential and limits of the human mind.
On this week's programme:
Pioneering research has looked into why certain people may become radicalised. Claudia finds out why depression and feeling socially isolated makes people more likely to sympathise with the actions of terrorists.
The Recovery Letters:
The Recovery Letters is a website that includes letters written by a range of people recovering from depression, which in turn will help those who are currently suffering. Creator, James Withey, tells us the story behind the idea for the site and how it inspires and helps those who are experiencing depression.
The bystander effect:
What causes other people to stand by and do nothing to help a suffering victim when other people are present? Drawing on examples such as the infamous Kitty Genovese case, where, allegedly, 38 witnesses did nothing to prevent her murder, this social psychological phenomenon is discussed.
This edition of All in the Mind is first broadcast on BBC Radio 4 on Tuesday 4th November 2014. For further details, and to listen online where available, please visit the BBC website.
