Two recent studies examine neural activity predictive of upcoming choices during value-
guided choice. Their results may be cast in light of a competitive winner-take-all decision …

Theoretical analyses of decisionmaking highlight the need for the values of each alternative
action to be mapped onto a single, common “utility” dimension (McFarland and Sibly, 1975) …

Publisher Summary This chapter focuses on challenge of studying the neurobiology of
decision-making. Establishing causal links between neural responses and perceptual or …

Standard economic theories conceive homo economicus as a rational decision maker
capable of maximizing utility. In reality, however, people tend to approximate optimal …

When choosing between two options, correlates of their value are represented in neural
activity throughout the brain. Whether these representations reflect activity that is …

Expected Utility Theory (EUT), the first axiomatic theory of risky choice, describes choices as
a utility maximization process: decision makers assign a subjective value (utility) to each …

To investigate the mechanisms through which economic decisions are formed, I examined
the activity of neurons in the orbitofrontal cortex while monkeys chose between different …

It has been suggested that many aspects of reward-guided behaviour can be understood
within the framework of a computational account of decision making. The account …

Previous research suggests that people evaluate options in at least two ways:(1) appraising
their overall value and (2) choosing between them. Here we test whether these processes …
