Hi Angelica,

You can always use regular javascript alongside PennController commands. So you can do this:

customTrial = label => variable => newTrial( label ,
    defaultText
        .center()
    ,
    // Display target word 
    newText("listen_for", "Listen for:")
        .css({"width": "300px"})
        .italic()
    ,
    newText("target_word", variable.target)
        .css({"font-size": "200%", "width": "300px"})        
    ,
    newText("next", "Press the spacebar to continue.")
        .css({"width": "300px"})
        .italic()
    ,
    newCanvas(300, 300)
        .add(0, 100, getText("listen_for"))
        .add(0, 150, getText("target_word"))
        .add(0, 250, getText("next"))
        .print()
    ,
    newKey(" ")
        .wait()
    ,
    clear()
    ,
    // Play audio stimulus and record reaction time
    newImage("fixation_cross", "fixation_cross.png")
        .size(300, 300)
    ,
    newCanvas(300, 300)
        .add(0, 0, getImage("fixation_cross"))
        .print()
    ,
    newKey("reaction_time", " ")                   
        .log("all")                                 
    ,
    newAudio("stimulus", variable.stimulus)
        .play()
        .wait() 
    ,
	clear()
    ,
    // Comprehension question
    (variable.question?[newText("question", variable.question)
        .cssContainer({"width": "600px", "font-size": "150%", "height": "50px"})
    ,
    newText("answer_1", variable.answer_1)
        .cssContainer({"width": "300px"})
    ,
    newText("answer_2", variable.answer_2)
        .cssContainer({"width": "300px"})
    ,
    newCanvas(600, 300)
        .add(0, 150, getText("question"))
        .add(0, 200, getText("answer_1"))
        .add(300, 200, getText("answer_2"))
        .print()
    ,
    newKey("FJ")
        .wait()
        .log()
    ]:null)
)
.log("group",       variable.group)
.log("item",        variable.item)
.log("condition",   variable.cond2)
.log("target",      variable.target)
.log("correct",    	variable.correct)

Then you can use it like this:

// experimental item trial 
Template("test_items", customTrial("items") )

// Filler item trial 
Template("test_fillers", customTrial("fillers") )
