Mathematical task

[Shai Aviram]

Hello,

I need to design a mathematical task

this is a simple task in which the student will see 10 mathematical exercises and he needs to solve them sequentiality (from top one to the last one) 

to design this task I need the ability to present a set of exercises (vertically) and allow user the answer each exercise (input field) and see what he types on screen. and allow him to advance to the next exercise 

it should something like this:

223 + 123 = 346  (example for answer exercise by student)

120 + 150 = 270  (example for answer exercise by student)

300 + 400 = ____ (this is the current exercise the student need to answer)

150 + 150 = ____  (this is the next exercise for the student) 

and so on...

I would like to know if this design is possible to be designed in E-prime?

Thanks in advance.

Do you need millisecond precision for stimulus & response times? If
not, then you might find it easier to do this in plain
HTML/CSS/JavaScript/ActiveX in a web browser, or maybe with something
like Empirisoft MediaLab.

Otherwise, to answer the question asked, yes, you could do this with
E-Prime with some effort. I leave it to others to provide details.

David thank you for the quick replay

I would need to register students respond in millisecond precision.

so i`m guessing HTML may be less for me? 

Nevertheless , if it is possible, I prefer to user E-prime since my University uses the E-Prime program.

Thanks,

Shai.

Hi,

Shouldn’t be all that hard at all, but David touches on an important topic: you need to think deep and hard about how you wish to design it. Why, for instance, if you’re interested in millisecond precision, are you showing all questions at the same time? It will take less time to answer question 10 than question 1, for many reasons: because of training (motor, cognition, etc), because perhaps you need to move the mouse, but also because presumably, your students will have read, for instance, a bit of question 5 before they have answered question 1 – therefore, some previewing can be assumed. How do you know, then, that the ms between answering question 4 and answering question 5 reflect the cognitive processing time of question 5? These kinds of uncertainties will make it useless to record reaction time, certainly in milliseconds. E-Prime is generally really great for very well specified designs, for instance:

1)      Show fixation.

2)      Show equation 223 + 123 = 346. Centrally on the screen, until response.

3)      Subject responds LEFT if the answer is correct, or RIGHT if the answer is incorrect.

4)      Repeat, from random list, and include 50% wrong answers as well (for example 223 + 123 = 364, which has similar visual appearance).

This, I think, is the level of detail in which E-Prime shines; other levels are possible, but are, as David suggests, probably best investigated with a different approach. I hope you find my comments helpful.

 

Best,

Michiel

Shai,

Regarding timing quality with HTML, etc... The last time I looked at
this, web browsers used the system clock, and the MS DOS/Windows
system clock ran with a default resolution of about 55 ms. That was
many years ago, and for all I know things have changed since
then. That also applied only to MS DOS/Windows. Of course, using
HTML, etc., you could run the program on other platforms (e.g.,
Apple, Linux), and their system clocks may provide different
resolutions -- as I recall, when I tested this with a Macintosh
(before OS X) I got 1 ms resolution. You would have to run your own
timing tests on any platform, and also bear in mind that *resolution*
is not the same as *accuracy*, as discussed, e.g., in the E-Prime User's Guide.

Given all that, I would find HTML, etc. suitable for designs that
required resolution no better than, say, 100 ms. For anything
better, I would go to E-Prime, DirectRT, MATLAB, PsychoPy, C/C++/C#, etc.

Hello,

I would like to ask if anyone knows if a simple DRM (Deese-Roediger-McDermott) e-prime script is available for use in research. It is a very widely used task for Psychology in which word lists are presented followed by a recognition task. It's often presented orally but lends itself to text presentation with E-prime. Rather than create a whole new version, I would like to use a previously accepted version if possible. If anyone knows of or has access to such a script, please let me know. Thank you very much!

I implemented one about 10 years ago -- I'm sure there's a newer one somewhere. It's super-basic, but it seems to work with the newest version of E-Prime, and it has the word lists, etc.

HTH,
Susan

[Shanna E. A. Hegerty]

Thank you! Yes, this message had the wrong subject as I accidentally replied to an old message to send it. I figured someone had made a DRM for E-prime and was curious to know if there was an "officially" accepted version. It seems that too often a bunch of labs come up with different versions of the same task and then it's difficult to compare results across studies. Thank you very much for prompt reply!

Thank you all for detailed and comprehensive answers.

you helped me very much.

as you pointed I`m now going to do some homework regarding the specific experiment design.

I just wanted to get a brief understanding if it even possible.

one last small question, as this task should simulate a real math test (as in school)

I need to set a timer for each block (block = set of exercises)

I know how to set a time limitation per response, but can I do it in the block level??

Thanks again!

This group is really helpful!

[Cognitology]

Hi,

You can easily do this at the block level by setting the list to exist after …. ms.

Best,

Michiel
