I don’t think it’s an image error, or anything to do with the survey.
Using developer tools I’ve identified that the line causing the error is in a text component:
InstructionSCID1_text = new visual.TextStim({
win: psychoJS.window,
name: 'InstructionSCID1_text',
text: 'In a moment, we will ask you to press the space bar as fast as you can WHEN YOU SEE A SQUARE. However, before the square appears, you will see a sign that tells you what kind of a picture will appear after the square. There are two types of pictures. SEXY pictures show couples posed in a sexy way. SPORTS pictures show people engaged in some non-sexual, fun activity. \n\nPress the [SPACE BAR] for more information.',
font: 'Arial',
units: undefined,
pos: [0, 0], draggable: false, height: 0.05, wrapWidth: undefined, ori: 0.0,
languageStyle: 'LTR',
color: new util.Color('white'), opacity: undefined,
depth: 0.0
});
If I compare this with the previous text code I can see that the issue is that you have a mix of units.
Finish_Text = new visual.TextStim({
win: psychoJS.window,
name: 'Finish_Text',
text: '',
font: 'Arial',
units: undefined,
pos: [0, 0], draggable: false, height: 32, wrapWidth: undefined, ori: 0,
languageStyle: 'LTR',
color: new util.Color('white'), opacity: 1,
depth: -1.0
});
You are using pix units and InstructionSCID1_text fails because the text height is 0.05 pixels.
