About this Lecture


In this module, we ask what stress is and how it can be researched. We note that while the experience of stress is highly subjective, we can generally speak of two distinct types of stress: (i) acute stress and (ii) chronic stress. Next, we think about some of the aims of research into stress, such as identifying triggers and developing mechanisms for coping with stress. Finally, we look at different methods researchers use to investigate stress, including simulator training and laboratory tests such as the Trier Social Stress Test (TSST).


In this course, Dr Sarita Robinson (University of Central Lancashire) discusses the topic of stress. We begin, in module one, by thinking about how we can define stress before moving on to examine how the body responds to stress in module two. Module three looks at the impact stress has on our health and well-being, while module four explores different methods of measuring stress. Finally, in module five, we think about how we can manage and cope with stressful situations.


Sarita Robinson (Psychology BSc - Lancaster University; Cognitive Sciences MSc - Manchester University) completed her PhD in Cognitive and Neuroimmune Responses to Threat at Lancaster University before joining the School of Psychology at UCLan in 2005. Sarita’s research interests mainly focus on cognitive neuropsychology and psychobiology in relation to people in survival situations. Sarita is also interested in the link between dental health and Alzheimer’s disease, the health benefits of Green space and Post-Traumatic Growth after trauma. Sarita is also passionate about science communication and undertakes extensive public engagement work.
