Hi guys, I am modifying the Penn Emotion Recognition Task (ER-40), which presents images of faces and then has the subject choose what emotion they saw. I would like to simply add another image before each face is shown, but I am struggling on how to do this. Where in the code can I add the image? <trial emotionRecognition>
/ inputdevice = mouse
/ ontrialbegin = [
values.target = list.itemnumbers.nextindex;
if (substring(item.images.item(values.target), 0, 1) == "F"){
values.gender = 1;
} else {
values.gender = 2;
};
if (substring(item.images.item(values.target), 1, 1) == "H"){
values.emotion = 1;
} else if (substring(item.images.item(values.target), 1, 1) == "S"){
values.emotion = 2;
} else if (substring(item.images.item(values.target), 1, 1) == "A"){
values.emotion = 3;
} else if (substring(item.images.item(values.target), 1, 1) == "F"){
values.emotion = 4;
} else if (substring(item.images.item(values.target), 1, 1) == "N"){
values.emotion = 5;
};
if (substring(item.images.item(values.target), 2, 1) == "X"){
values.intensity = 1;
} else if (substring(item.images.item(values.target), 2, 1) == "Z"){
values.intensity = 2;
} else {
values.intensity = 0;
};
]
/ stimulusframes = [1 = target, happy, sad, anger, fear, neutral, wall, testInstructions1, testInstructions2]
/ validresponse = (happy, sad, anger, fear, neutral)
/ iscorrectresponse = [
return(
(trial.emotionRecognition.response == "happy" && values.emotion == 1) ||
(trial.emotionRecognition.response == "sad" && values.emotion == 2) ||
(trial.emotionRecognition.response == "anger" && values.emotion == 3) ||
(trial.emotionRecognition.response == "fear" && values.emotion == 4) ||
(trial.emotionRecognition.response == "neutral" && values.emotion == 5));
]
/ ontrialend = [
values.countCorrect += trial.emotionRecognition.correct;
list.ACC.appenditem(trial.emotionRecognition.correct);
if (trial.emotionRecognition.correct){
list.corrRT.appenditem(trial.emotionRecognition.latency);
};
list.RT.appenditem(trial.emotionRecognition.latency);
]
/ posttrialpause = parameters.ITI
</trial>
<trial finish>
/ inputdevice = mouse
/ ontrialbegin = [
if (parameters.showSummaryFeedback == false){
text.SummaryFeedback.skip = true;
};
]
/ stimulusframes = [1 = clearscreen, thankYou, SummaryFeedback, finish]
/ validresponse = (finish)
/ recorddata = false
</trial>
