Imperfect choice and the brain: uncertainty, value and decision-making.

Scheme: Sir Henry Dale Fellowship

Organisation: University of Cambridge

Dates: Mar 2014-Mar 2019

Value: £972,220

Summary: I aim to study how our brains compute the values used to guide choice in the face of different sources of uncertainty. I will focus on value-based choices (e.g. which investment should I make?, who should I marry? and what should I eat?) a type of decision that plays a key role in our lives. While in the past decade the field of neuroscience has produced a good understanding of how the brain copes with sensory uncertainty while we make perceptual decisions (e.g. which image is brighter?), much less is known about how uncertainty affects value-based choice. I aim to describe this process, isolating the sources of uncertainty that affect value-based choice at both the neural and behavioural level, using the level of confidence in the choice reported by the subjects as a measure. While confidence in ones course of action is critical for day-to-day behaviour, as when a financial advisor justifies his or her choices to clients, little is known about exactly how our brain encodes confidenc e.
