This data set is a bivariate series of reaction times and accuracy scores of a single subject switching between slow and accurate responding and fast guessing on a lexical decision task. The slow and accurate responding, and the fast guessing can be modelled using two states, with a switching regime between them. The dataset further contains a third variable called Pacc, representing the relative pay-off for accurate responding, which is on a scale of zero to one. The value of Pacc was varied during the experiment to induce the switching. This data set is a subset of data from experiment 2 in Van der Maas et al, 2005.
