Illustration of training manipulation on prior mean in probability density distribution. The red dotted distribution represents the shifted prior distribution induced by the manipulation (i.e., in phase 2), the black solid distribution represents the original prior distribution in phase 1 and 3. The x-axis is the horizontal location of the screen. The arrow refers to the leftward direction of the manipulation.
