_D_e_s_c_r_i_p_t_i_o_n:

     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 from a
     single subject from experiment 2 in Van der Maas et al, 2005.
