The Effects of Public Messages on Air Quality

Claudia Hammond talks to Daniel Freeman, a clinical psychologist at the University of Oxford about a trial into a new talking treatment for people experiencing persecutory delusions. Called the Feeling Safe programme, the trial has had positive results and has transformed the lives for many of those receiving it, including Joe, one of the trial participants. Claudia talks to Professor Catherine Loveday about the lives and work of psychiatrists Aaron T Beck and Professor Sir Michael Rutter who have both died. She also talks to social psychologist, Fanny Lalot about how different signs at a railway level crossing in Canterbury might influence drivers to turn their engines off while they're waiting for the barriers to lift. Also in the programme, Professor Catherine Loveday talks about a new study looking at how taxi drivers brains help us understand and improve navigational skills. Producer Pamela Rutherford
