PennController( ... )
or PennController( "label" , ... ) (since version 1.0)
The PennController command lets you write the script of your trials. You can use it in three environments: on its own to create a trial (since version 1.0), within PennController.Template to generate items from a spreadsheet, or within the definition of the Ibex variable items to create single elements.
You pass a sequence of commands as its parameter to define the script of your trial. Optionally, you can also pass a string as the first parameter to give a label to your trial which you can refer to when defining the experiment’s sequence order in shuffleSequence or (since version 1.1) in PennController.Sequence. If you specify no label string, the trial will be labeled unlabeled.
Example:
[js try=”data” highlight=”1,8″]
PennController(
newButton(“helloworld”, “Hello world!”)
.print()
.wait()
);
PennController.Template(
row => PennController( row.Type ,
newButton(“button”, row.ButtonText)
.print()
.wait()
)
);
[/js]
Creates one trial labeled unlabeled with a single button on the screen reading Hello world!, and generate one-button trials from a spreadsheet, assigning the text from its Type cells as their label and the text from its ButtonText cells as the button’s text (see PennController.Template).
