How Motivation Biases Perception

The idea being that we don't always see the world as it is, we see it as how we want it to be or wish it to be. Your work also looks at how you briefly mentioned how motivation biases perception. Could you explain a bit about that and some of the work you've done in that area? Of course it's a broad topic area I can only focus on I would say a snippet of it but one of the things that I study is wish for seeingHow people see what they want to see.
