==Notes== It follows the procedure described by Wilkinson fairly reasonably, with several exceptions. * As with the Wilkinson device numeric feedback is given; however unlike that device a running counter is not displayed. The presence of feedback can be controlled with the variable giveFeedback. * There are three different types of testing to choose from to determine whether the experiment is complete: time-based, trial-based, and block-based. These are controlled by the testType variable (1, 2, or 3) ** Time-based will run until a certain time has elapsed ** Trial-based will run until a specific number of trials have completed ** Block-based allows one to use an isi-block, which gets sampled from without replacement, and then reshuffled until the number of blocks has elapsed * In addition, when the useContinuous variable==1, it will choose a continuous stimulus presentation time between the min and max of timeInterval. Otherwise, it will sample from the set in timeIntervals
