The Nature-Nurture Debate

About the Course

In this course, Dr Lydia Kearney (University of Kent) explores the nature ‘versus’ nurture debate in psychology. The first lecture prefaces the course by proposing the removal of ‘versus’, predicated on the origin of any human behaviour being too complicated to be explained by just one set of factors. The second lecture takes a deep dive into the nature side of this debate, introducing Mendelian genetics and explaining the concept of heritability. The third lecture explores the nurture side of this debate, outlining a timeline, from the ancient philosophers who proposed the tabula rasa, to modern research on environmental factors that impact aggressive tendencies. Next, we bring in a modern perspective on the interactions between environmental and genetic factors when explaining phenotype expression. In the fifth and final lecture, social anxiety is used to exemplify how environmental and genetic factors, as well as their interactions, can predict the prevalence and experience of the condition.
