Applying Psychology We would like to dedicate this course to the memory of Brenda Smith, Psychology Staff Tutor and member of the course team, who died during the final year of the course’s production. She had been a Psychology Staff Tutor since 1995, first in Scotland and then most recently in Ireland, but her close association with the Open University stretches back much further than this. She was an Open University student herself and then later returned to teach and was a tutor who enthused and supported very many students throughout their social science studies. At her funeral one of these students spoke very movingly of her warmth and energy and of the fact that she had really ‘made a difference’ to their lives. She certainly also made a difference to our DSE212 course team, where her commitment to education for mature students was clear in everything that she said and did, and her immensely hard work influenced many of our plans for the teaching and learning strategy of the course and the content of the texts. She contributed enormously at both a professional and personal level, particularly to theearlyworkofthecourseteam,andwehopethatherinfluenceonthecourse will shine through, helping it in turn to ‘make a difference’ to the lives of all the students who will study it in the coming years.

individuals experience stress when others in the same circumstances do not? How has learning theory been applied to treatment for post-traumatic stress disorder (PTSD)? What are the psychological explanations for autism? Are police officers better at detecting lies than the rest of us? How is social cognition and memory research relevant to interviewing witnesses to crime? What social psychological theories can explain computer-mediated communication? Does psychoanalysis inform our understanding of how we relate to others at work? You will find the answers to these questions and a multitude of others in Book 3, Applying Psychology, which is your final study block of the course. Soon you will need to decide which questions you are most interested in, as you are required to read only two of the seven chapters. To help you make that decision, we would here like to introduce you to the different
