Hi, Jeremy!
I’m coding a lexical decision task and I want participants no answer if the word they see on the screen is a Spanish word or not with 1 (yes) and 0 (no). I also want to include a timeout, so if they take more than 1000 they can’t answer anymore and the experiment goes on to the next stimulus.
I used the .success and .failure options to code this (thanks for your answers on previous threads!) however now I’m having problems when the answer is correct. If I press 1 or 0 before the 1000 time limit, it should move on to the next trial, however this is not working. I have to press the 1 or 0 two times for it to move on. Do you know what might be wrong in the code?Here is the relevant code:
newTrial("entrenamiento1", // Display all future Text elements centered on the page, and log their display time code defaultText.center().print("center at 50vw","middle at 50vh") , // Automatically start and wait for Timer elements when created defaultTimer.start().wait() , // Mask, shown on screen for 250ms newText("mask","########"), newTimer("maskTimer", 250), getText("mask").remove() , // Prime, shown on screen for 28ms newText("prime", "verde"), newTimer("primeTimer", 28), getText("prime").remove() , // Mask, shown on screen for 14ms newText("blanco"," "), newTimer("blancoTimer", 14), getText("blanco").remove() , // Mask, shown on screen for 46ms newText("mask2","########"), newTimer("maskTimer2", 46), getText("mask2").remove() , // Target, shown on screen until 1 or 0 is pressed newText("target","NARANJA") , newTimer("hurry", 1000) .log() .start() , newKey("answerTarget", "10") .log() .callback(getTimer("hurry").stop()) , getTimer("hurry") .wait() , getKey("answerTarget") .test.pressed() .success(getText("target").remove()) .failure(getText("target").remove(), newText("lento", "¡Muy lento! Recordá responder rápidamente.") .log() .print("center at 50vw","middle at 50vh") .center() .color("red"), newTimer("fail", "1000"), getText("lento")) , newText("*") .css("font-size", "x-large") .center().print("center at 50vw","middle at 50vh") , newTimer("*timer", 250) , getText("*") .remove() // End of trial )Also, the demonstration link is here: https://farm.pcibex.net/r/nwrPpa/
Thanks a lot!
Noelia.Hi Noelia,
All the Timer elements in your trial are
started andwaited for upon creation:defaultTimer.start().wait()This applies to the one named “hurry” too, so
newTimer("hurry", 1000).log().start()implicitly stands fornewTimer("hurry", 1000).start().wait().log().start()Remove
.wait()from the default commands, and include it explicitly where you need itJeremy
Hi Jeremy! I dowloaded the results file and I am having some problems identifying the key pressed in the lexical decision task. I put the .log command on both the newKey and the getKey, but on the results file it says (failed keypresses happened). I pressed the keys following a pattern, so there should be several 1 answers, several 0 answers, several null answers (which are time-out answers; this are actually displayed), several 1 answers and so on…
I also don’t understand why all the information about the pressed keys are at the bottom, and not on each trial. Do you see what the problem is?Here is the relevant code:
Template( "list.csv" , row => newTrial( "test" , // Display all Text elements centered on the page, and log their display time code defaultText.center().print("center at 50vw","middle at 50vh").log() , // Automatically start for Timer elements when created, and log those events defaultTimer.log().start() , // Mask, shown on screen for 250ms newText("mask","########"), newTimer("maskTimer", 250).wait(), getText("mask").remove() , // Prime, shown on screen for 28ms newText("prime",row.prime), newTimer("primeTimer", 28).wait(), getText("prime").remove() , // Mask, shown on screen for 14ms newText("blanco"," "), newTimer("blancoTimer", 14).wait(), getText("blanco").remove() , // Mask, shown on screen for 46ms newText("mask2","$$$$$$$$"), newTimer("maskTimer2", 46).wait(), getText("mask2").remove() , // Target, shown on screen until 1 or 0 is pressed newText("target",row.target) , newVar("rt") .global() .set(v=>Date.now()) , newTimer("hurry", 3000) .log() , newKey("answerTarget", "10") .log() .callback(getTimer("hurry").stop()) , getTimer("hurry").wait() , getKey("answerTarget") .test.pressed() .success(getText("target").remove()) .failure(getText("target").remove()) .log() , getVar("rt") .set(v=>Date.now()-v) , newText("*") .css("font-size", "x-large") .center().print("center at 50vw","middle at 50vh") , newTimer("*timer", 250).wait() , getText("*") .remove() // End of trial ) .log( "rt", getVar("rt")) // guardo el tiempo .log( "Group", row.Group) // Group o lista .log( "cond", row.cond) // condición (1, 2, 3, 4) .log( "cond_prime", row.cond_prime) // condición del prime (congruente, incongruente) .log( "cond_target", row.cond_target) // condición del target (congruente, incongruente) .log( "morf_prime", row.morf_prime) // morfología del prime (femenina o masculina) .log( "morf_target", row.morf_target) // morfología del target (femenina o masculina) .log( "rta_esperada", row.rta_esperada) // respuesta esperada (1 o 0, 1 para sí/palabra y 0 para no/nopalabra) .log( "tarea", row.tarea) // tipo de tarea (mujer_neutros; varon_neutros) )And here is the demonstration link: https://farm.pcibex.net/r/nwrPpa/
Thanks in advance!
Hi,
Use
.log("first")instead of just.log()so you can capture keypresses that do not validate awaitcommand on the Key element:newKey("answerTarget", "10") .log("first") .callback(getTimer("hurry").stop()) , getTimer("hurry").wait() , getKey("answerTarget") .test.pressed() .success(getText("target").remove()) .failure(getText("target").remove()) // removed this .log() as to not overwrite the first one ,Jeremy
