Application of behaviour analysis principles across everyday situations. This paper takes a closer look at how basic principles of behaviour analysis (e.g. operant conditioning) can be used across a range of situations to modify behaviour. Situations include consumer behaviour, physical activity and exercise, and education in the treatment of issues such as substance abuse and skills training for people with autistic spectrum disorders. A large component of this paper will focus on community behaviour change, looking at how we can modify everyday behaviours, such as reducing littering and petrol consumption and increasing pro-social behaviours such as foodbank donations and voluntary work. Group project work is involved, in which you will design and carry out an intervention to target a local community issue.
