mturk

• This repository contains codes for two online experiments (Amazon Mechanical Turk) to test human participant's irrelevant feature memory.
• See here for more details.
• Both experiments were designed by using Javascript, HTML, and CSS.
• In the actual mturk experiments, more trials were used.

Experiment 1: Change localization to test one's irrelevant color memory

Main file: de_ori_example.html

• At the top of the html document, you can find related Javascript files.

Procedure

• Participant see a brief display of 4 colored oriented ellipses.
• After a delay, another brief display appears. One of the ellipses has changed its color. Another randomly chosen ellipse has changed its orientation.
• For the first 5 trials, participatns are asked to find the location of orientation change.
• In the 6th trial, participatns are asked to find the location of color change.

Experiment 2: Delayed estimation to test one's irrelevant color memory

Main file: testcol.html

• At the top of the html document, you can find related Javascript files.

Procedure

• Participant see a brief display of a colored oriented ellipse, followed by a delay.
• For the first 5 trials, participatns are asked to recall the orientation of the ellipse.
• In the 6th trial, participatns are asked to recall the color change.
