Basic psychometrics. (A) Probability of purchasing the product as a function of the net value (product value – price). (B) Reaction times as a function of the magnitude of the net value. (C) The number of fixations in a trial, as a function of the magnitude of the net value. Black circles indicate data from the odd-numbered trials of the subject data, and red dashed lines indicate the simulated data from the aDDM. Bars are standard error bars, clustered by subject.
