The Neuroscience of Nudge (360G-Wellcome-202434_Z_16_Z)

<p>Nudges are simple behavioural methods designed to influence decision making by taking advantage of people&rsquo;s implicit biases. One important type of nudge is known as &ldquo;anchoring.&rdquo;&nbsp; The simple presentation of an irrelevant number affects people&rsquo;s decisions by shifting estimations towards that number. This behavioural effect is well understood although the mechanism behind the unconscious bias remains unclear.&nbsp; The brain bases of this effect has received surprisingly little attention in the literature. One study found that the medial prefrontal cortex played a crucial role in anchoring theory-of-mind decisions in a social context, suggesting that activity within cortical networks intrinsic to the task is shaped by this extrinsic information. I propose to initiate this investigation by piloting an fMRI experiment to investigate the neural correlates of anchoring in reasoning about uncertainty. The aim is to collect a preliminary data set from a small sample of healthy adults (n=12) to explore whether the experimental paradigm: yields robust behavioural anchoring effects, identifies brain regions whose activity is affected by these anchoring effects, and tests whether these effects are parametric modulated.&nbsp;I predict that within prefrontal regions engaged by the task, I will observe parametric modulation based on the amplitude of the behavioural anchoring effect.&nbsp;</p>
