The (quadratic) Lambda Slider.
(A) The interface of the slider. The payoff to oneself (red bar) and payoff to the target (blue bar) change continuously as the participant moves the slider. (B) The payoff functions of the quadratic Lambda Slider used in Experiment 1 (a = 11.25, ,
,
and
). If we plot
and
against each other, we get a parabolic curve similar to Fig 1D. (C) Examples of the participant’s utility function for different
s. The slider position that maximizes each utility function is marked, which is an identity function of the participant’s
.
