speed: Speed Accuracy Switching Data
Description
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.format
