My 2nd Script: Beginner Images

howto_user

This is a basic image memory task. It shows a series of images, then a text field for subjects to type what they remember.

My 2nd Script is like Script 1, but using images. It begins with an instruction to remember the objects in the following images. Then it displays eight images, one at a time, for 2 seconds each, with a 1-second blank screen in between. Last, it displays a text field with a label asking the subject to type the objects they remember. The subject’s response is automatically saved to the script’s data.

Topics introduced: preload(), image.await(), setimage(), hideimage()

My First Eight Scripts

If you are a registered user and signed in, you can here copy this script and its stimuli to your own account, where you can edit it and change it in any way you want.

It is absolutely free to register (no credit card info asked!). You can then instantly copy this experiment with one click and edit it, change its accompanying texts, its landing page, stimuli, etc. Invite your colleagues, friends, or students to check out your experiment. There is no limit on how many people can do your experiment, even with a free account.

The catch? There is no catch! Just keep in mind that with a free account, you cannot collect data. For teaching that is usually not a problem. For research, prepaid data collection (unlimited subjects) starts as low as €10.00 for a 10-day period.

/* To show images, you must upload them first, using the cloud-with-an-arrow
icon in the bar above. Drag your images into the box, then press "Update".
You can confirm they've successfully uploaded in the Quick Reference Panel to
the right, under "Files and Stimuli --> Image Files".*/

/* "Preloading" images (next 9 lines) is highly recommended. It prevents the
script from starting until all images are fully loaded. Otherwise, if a subject
uses a slow system, an image may load slowly mid-study & ruin precise timing.*/
