Decisions and decision making
Decisions are ubiquitous feature of our cognitive lives. We make decisions when selecting consumer products in the supermarket, or when choosing for whom to vote in elections. Psychologists and neuroscientists often think of decisions as occurring when animals make a commitment to a course of action, such a choosing to turn left rather than right at a fork in the road. Typically, animals make decisions that will maximise their outcomes, and/or allow them to achieve a goal. Less intuitively, we can also think of decisions are reflecting a commitment to a categorical proposition ('that is a chair'). Decisions of this sort, about perceptual stimuli, help us organise the sensory world into discrete categories. In the lab, we study information processing steps that occur as these commitments are made, charting the neural mechanisms that occur during human decision-making.
