We discuss the implications of these different outcomes, noting the evident differences between the source of uncertainty and how information about uncertainty is acquired in motor and economic tasks.
Keywords: decision making, risk, neuroeconomics, movement planning under risk, Bayesian decision theory, expected utility theory Risky decisions and movement planning Uncertainty plays a fundamental role in perception, cognition and motor control and a wide variety of biological tasks can be formulated in statistical terms.
We will show that framing behavioral tasks in the language of statistical decision theory enables a comparison of performance between motor tasks and decision making under risk.
Research concerning decision-making seeks to understand how subjects choose between discrete plans of action that have economic consequences [ 4 ]. Here, we are concerned primarily with the former. The key difficulty in making such decisions is that no plan of action lottery available to the subject guarantees any specific outcome.
We review recent experimental work in movement planning [ 6 — 9 ] in which humans perform speeded movements towards displays with regions which, if touched, lead to monetary rewards and penalties Box 1. Our work shows that humans do very well in making these complex decisions in motor form. This outcome is particularly surprising since humans typically do not do well in equivalent economic decision-making tasks as we describe next.
