The next step is to define an expt element that defines the flow of blocks in the experiment. The expt element is defined as follows:
<expt> / preinstructions = (intro, task, taskreminder) / postinstructions = (end) / blocks = [1=practice; 2,3=critical] </expt>
The expt element is simple. The preinstructions attribute begings the expt by showing subjects the 3 pages of instructions, "intro", "task", and "taskreminder". The postinstructions attribute specifies final instruction page named "end" to be displayed at the conclusion of the experiment. The blocks attribute specifies that 1 practice block is run followed by 2 critical blocks.
Finally, we'll do a little fine tuning by specifying some default settings using the defaults element.
<defaults> / fontstyle = ("Courier New", 16pt) / posttrialpause = 500 </defaults>
The fontstyle attribute specifies that all stimulus and instruction text should be displayed in a 16pt "Courier New" font. The postrialpause attribute specifies that a 500 ms pause should occur at the end of each trial.
The experiment is now complete! You can run the experiment by selecting the "Run" command on the "Experiment" menu.
