Description Usage Format Source Examples
This data set is a bivariate series of response times and accuracy
scores of a single participant switching between slow/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 participant A in experiment
1a from Dutilh et al (2011). The data here is the first series of
168 trials. The
speed data set in the
has two more series of 134 and 137 trials respectively.
A data frame with 168 observations on the following 3 variables.
a numeric vector of response times (log ms)
a numeric vector of accuracy scores (0/1)
a numeric vector of the pay-off for accuracy
