| Perfect — you want to create a symbolic link inside your web directory that points to the real week10_taskset folder in the project root. | |
| Since you’re currently in /Users/Susan/Desktop/psy1903, you can run this: | |
| ln -s ../week10_taskset web/week10_taskset | |
| Wait — that’s if you’re inside web/. But since you said you’re in the project root (psy1903), the correct command from there is: | |
| ln -s ../week10_taskset web/week10_taskset |
Using a HTML iframe element, you can embed your jsPsych experiment directly in a question within your Qualtrics survey - E.g.:
<iframe
src='https://susanbuck.github.io/psy1903/projects/lexical-decision/?qualtricsId=${e://Field/ResponseID}'
id='experimentEmbed'>
</iframe>| // Welcome | |
| let welcomeTrial = { | |
| type: jsPsychHtmlKeyboardResponse, | |
| stimulus: ` | |
| <h1 class='welcomeHeader'>Welcome!</h1> | |
| <p>In this experiment, you will be shown a series of words.</p> | |
| <p>Press the letter <span class='key'>F</span> if the word is positive.</p> | |
| <p>Press the letter <span class='key'>J</span> if the word is negative.</p> | |
| <p>Press <span class='key'>SPACE</span> to begin.</p> | |
