My 4th Script: Intermediate Words Demo Experiment

### My 4th Script: Intermediate Words

howto_user

This is the same word task as My 1st Script, but created using a more advanced method.

My 4th Script shows the eight words to be remembered using a “for-loop” rather than typing out the steps eight times (like in My 1st Script). This is a more concise and less error-prone way to produce an identical task.

Topics introduced: var, arrays, for-loop

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 i;
var vocab = ["apple","chair","tent","bowl","clock","bike","tree","cat"];

instruction("Remember as many of the following eight words as you can.");

/* This is called a "for-loop". It means we don't have to retype the same steps
over and over. The arguments translate to "start counting with i equalling 0,
keep repeating the loop (i.e., the steps inside the curly brackets) as long as
i is less than the number of elements in "vocab" (i.e., 7 because counting
starts at 0), and increase i by 1 each time that the loop is completed.*/

for (i = 0; i < vocab.length; i = i + 1)
{
text(vocab[i]); // Instead of writing the word to be shown inside the
await(2000);    // brackets, we simply refer to the i-th position of "vocab"
clear();
await(1000);
}

largeinput("Please type the words that you can remember.","words_recalled");```
