Online Tool for Perceptual Experimentation

Start using FOLERPA now!

To start using FOLERPA, please sign up. Click on the USER SIGN UP button on the Home screen.

You will then access a form where you must fill in some data to complete your registration.

All signed up?

You can now access your researcher profile from the Home screen. Within this administration area you can create a test, manage tests you have already completed, distribute your tests, and carry out basic statistic analyses.

You will find these options in the left-hand side menu, together with a manual, a glossary, and a number of references that you can download.

Sign out

To sign out, please click on the field containing your username, in the upper right-hand corner, and then click on SIGN OUT.

Top menu

You can browse through the top menu without signing out. If you want to go back to the administration area, you can simply click on the tab that drops from the top menu.

Side menu

Remember that all the test administration options are available from the left-hand side menu. You can access any of the resources whenever you wish. Please keep in mind that if you change modules while in the middle of creating a still unfinished test, you will lose all the information you have entered so far.

To create a new test please select the option CREATE TEST from the left-hand side menu in the researcher administration area.

This option will give you access to the test creation space, with different sections you can fill in according to your preferences and the test you want to carry out. This test elaboration module is made up of several forms:

1. Test data

In the first screen you must enter information about the test you will carry out: title of the test, research aims, and a unique code for each test.

2. Participant data

In this section you can choose the data you want to collect from the participants in the experiment. The section is set up so that researchers may offer a series of closed-ended options for participants to choose from.

3. Variables

In this area you must enter traits associated to your stimuli and possible values for each of these categories. For instance, you can enter the category place of articulation, with the values bilabial, dental, and velar.

4. Instructions

In this area you can enter instructions to be read by participants at the beginning and/or end of each test.

5. Trials

In this section you must predefine the trials included in your test. You can select the number of stimuli to appear in each case, the number of response options, trial repetitions, trial order, and the length of intervals between stimuli repetitions and the presentation of each case.

6. Characterization

In this section you can characterize the trials included in your test. In this form, you can enter the questions for the participants and the possible answers. Here you can also upload the audios you will use as test stimuli.

7. Blocks

In the BLOCK CHARACTERIZATION section, you can determine the number of blocks your test's trials are to be divided into. You can also choose any repetitions of the blocks, as well as the text that will be presented to the participants during the interval between blocks, should there be more than one block.

8. Preview test

After completing the parameter entry you can preview the test as it will be shown to participants during the experiment. This way, should you find any errors, you will be able to modify any part of your test.

After previewing the test, you will be shown an overview of the information regarding your test.

Click SAVE to finish and save your test.

The CREATE TEST option allows creating detection tests, AXB, AX, and other types of discrimination tests, identification tests, or scale evaluation tests. For more information, please see the Manual.

You can see your tests anytime from the panel TEST MANAGEMENT. Here you will find all the tests you have created, you will be able to preview them, see the information entered when you created the tests, and preview responses from participants who have already completed them. You can also clone or delete tests you have already created.

Information

You can see data regarding any test, such as the purpose of the research, the aims of a test, the code of a test, as well as information about the number of trials a test consists of and the associated categories or stimuli. This will allow you to access more easily any test you might be looking for.

Preview

After completing the parameter entry you can preview the test as it will be shown to participants during the experiment. This way, you will be able to remember exactly what your test looked like.

Participant responses

You do not need to download the result table in order to see the participants' responses.

Clone

Would you like to replicate a previously created test with minor modifications?
You can clone a previously created test. The new test will maintain all the parameters of the original, but you can make any changes you need. You only need to enter a new code and upload new audios.

Clear

Remember that you can delete the tests you no longer need or want in your workspace.

This module allows you to distribute a test to the participants in your experiment. There are several ways to do this:

  • By sending the URL to the participants, who will then directly access your test.
  • By sending the participants the link to the access page to the participant profile, and the code of the test you want them to complete.

In this second type of distribution, participants will go to an access page, where they will have to enter their username, password, and the test code.

Participants must register to be able to complete the tests. The same access page can be used to register.

New participant user

To complete the tests, participants must individually register on the platform. Registering as a participant user is just as easy as registering as a researcher. All you have to do is click the USER SIGN UP button on the page they have received in the link

Participants will go to a new participant user sign up page, where they will have to fill in some fields to complete their registration:

Once registration is completed, participants will return to the page they have received in the link.

This module allows you to work with the test data. You can see the information regarding each test and decide what data you want to work on. You can also preview participants' responses.

It includes a basis statistical analysis module which allows you to obtain a descriptive analysis of your test, of the participants who completed it, and their responses. Section under construction.

You can also download data tables for each of your tests. There are three types of tables:

Participant response table

This table contains the responses given by the participants who completed a particular test. Each response corresponds to a row in the table. Therefore, each line also contains the participant ID, the question that he/she responded to, the stimulus he/she heard, the correct answer, and the answer the participant chose. Moreover, the date of completion of the test and the duration of the experiment are also stated.

Participant data table

This table contains the data the participants were asked to provide, which are selected in the second step of TEST CREATION. Therefore, the number of columns in the table will depend on the number of categories that intervene in the creation of the test, and the number of rows will depend on the number of participants who complete the test.

Variable table

This table contains data regarding stimuli. In the third section of TEST CREATION, researchers must enter the characteristics that are relevant to their study, linked to the stimuli included in the test. The characterization of each of the test stimuli is shown here.
