3. Partial Reinforcement Theory
About this Lecture
In this lecture, we think about partial reinforcement theory, focusing in particular on: (i) the dramatic economic fallout from gambling addiction; (ii) the process of simple reinforcement, whereby a single behaviour can be encouraged by rewarding its presence; (iii) gambling machines’ usage of partial variable reinforcement by only rewarding the gambler periodically; (iv) the differentiated response to repeated losing, either being to walk away from the loss or to keep playing, with the expectation that a win will be soon.
In this course, Dr Ashok Jansari (Goldsmiths, University of London) explores non-substance addictions, specifically gambling addiction. In the first lecture, we think about how addiction can be described and defined as a concept. In the second lecture, we think about some of the risk factors for developing an addiction. In the third lecture, we think about how gambling machines use partial variable reinforcement, which can generate an addiction. Next, we think about some of the cognitive biases which can lead to addictive behaviour, including the near miss bias, the recall bias, and the gambler’s fallacy. In the fifth and final lecture, we think about some patterns which arise in the process of overcoming addiction, specifically looking at Prochaska’s six-stage model of behaviour change.
