Choose randomly from previous steps (case 10618)

[ayalabone]

Hello,

In the experiment I am trying to the design there is a training phase and a test phase.

The training phase is built from 240 steps, in each step the subject needsto choose A or B as the correct answer.
In the test phase I would like Direct RT to choose 50 steps randomly from thetraining phase, and display them again as the test.

Is this possible?

Thank you,

Ayala
