Getting back on track after the unexpected happens: decision making in predictable and unpredictable environments
Our brains are continually making decisions. One of the commonest – done several times every second - is deciding which part of the world to look at next. It is known that the time to look at a randomly appearing target reflects the timing of the brain's decision-making processes, although this relationship is less well established when events occur in patterned sequences. Such sequences are important as many of our daily actions consist of routine patterns that are believed to be controlled by special parts of the brain. Our project uses both behavioural and brain imaging (fMRI) methods to investigate decision-making during patterned sequences, as well as what happens when an expected pattern is disrupted. This work will help understand how the brain makes a very common type of decision in the natural world.
