It is likely that much of the way that our brain processes information takes place outside of our conscious awareness. For this reason, much of the behaviour we study in psychology is governed my non-conscious processes and mechanisms. In my own work I study the nature and origin of tics (i.e., the involuntary movements and vocalisations seen in people with Tourette syndrome). In addition, there is a good deal of evidence to suggest that our concept of free will over our behaviour and our choices is often something of an illusion
One of the topics I study is cognition, which essentially is the process of thinking. Examples include attention, memory, and planning. Most of the time, these thinking processes occur automatically and is not something we actively think about. This can make them very difficult to study, but there are tasks people can complete that allow researchers to study cognitive ability.
I look at bias held by witnesses to crime, the police and jurors. These are usually not biases that we are aware of, but if we don’t have clear systems in place in minimise their effects, they can lead to miscarriages of justice – innocent people going to jail, and guilty people avoiding conviction.
