Attentional Blink Experiment

Jaap Murre

This is a fairly standard attentional blink demo (e.g., https://en.wikipedia.org/wiki/Attentional_blink).

In one condition the word CAT masks the ensuining target stimulus, the letter X.

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.

var ms = 120; // item presentation time in ms
var condition1 = getwords("condition1.txt");
var condition2 = getwords("condition2.txt");
var i;

text("Get ready to spot the X in the first stream");
await(2000);
text("");
await(1000);
text("Press the space bar to start. It is pretty fast!");
awaitkey(" ");
text("-");
await(1000);

// This presents the stimuli in condition 1
for (i = 0; i < condition1.length; i++) {
    text(condition1[i]);
    await(ms);
}
radio("Dit you see the letter X?",['yes','no'],"x1");
input("Which words did you see, if any (i.e., not letters)?","word1");


text("");
await(1000);
text("Press the space bar to start the second stream.");
awaitkey(" ");
text("-");
await(1000);


// This presents the stimuli in condition 2
for (i = 0; i < condition2.length; i++) {
    text(condition2[i]);
    await(ms);
}
radio("Dit you see the letter X?",['yes','no'],"x2");
input("Which words did you see, if any (i.e., not letters)?","word2");



text("Thank you for participating!")
await(2000);
