5. External Mechanisms of Addiction
About this Lecture
In this lecture, we go beyond the internal, biological mechanisms of addiction from lecture four, to explore external mechanisms, focusing in particular on: (i) learning theory; (ii) some typical learning processes that may occur in smoking, such as the smell and taste of tobacco being associated with the effects of nicotine; (iii) social learning factors; (iv) cues which may create an environment more conducive to relapse, in the case of a person attempting to overcome their addiction.
In this course, Professor Marcus Munafò explores addiction in the context of smoking and smoking cessation. In the first lecture, we think about some key physical and psychological withdrawal symptoms of smoking, before exploring the fact that the positive outcomes of smoking may be simply an absence of these withdrawal symptoms. In the second and third lectures, we explore the internal and external factors which can influence the likelihood that someone may become addicted to a substance. In the fourth and fifth lectures, we continue this differentiation between internal and external factors, discussing internal, biological mechanisms of addiction and external, learning mechanisms. In his final note, Professor Munafò brings forward the idea of understanding addiction as a disorder of learning.
Marcus Munafò is a professor of biological psychology and associate pro vice-chancellor of research culture at the University of Bristol. Professor Munafò’s research is focused on understanding health behaviours related to tobacco and alcohol use, informing current debates on tobacco product packaging. With experience in an array of research methods, one of Professor Munafò’s other interests is in whether participant incentives in scientific experiments provide an optimal level of robustness and reproducibility. Some of Professor Munafò’s recent publications include ‘Acceptability of integrating smoking cessation treatment into routine care for people with mental illness’ (2022) and ‘Applying Mendelian randomization to appraise causality in relationships between nutrition and cancer’ (2022).
