Decision Making: Big and Small - Dr Chris Donkin

What is this research about?

We are constantly making decisions. These decisions range from being large –which phone to buy next, to incredibly small – the colour of the upcoming traffic light. We are interested in trying to understand how such decisions are made, both big and small. For example, how do we combine all of the relevant (and irrelevant) pieces of information when choosing which new phone is best? What happens when we are forced to make such decisions quickly?
