I want to run an SPR experiment where participants will read sentences at their own pace. My problem lies in the fact of using 2 different languages English and Arabic at the same time. I tried it with Linger, but I failed to upload the files. Could any one of you suggest another software by which I can run SPR tasks in Arabic and English?
You can use Ibex, if you want to run it online: http://spellout.net/ibexfarm/
But in any case you should be able to upload the files in Linger, you'll need to do it centered since Linger doesn't support right-to-left languages. And you should check the encoding of the files. It should be ISO 8859-15 and not UTF-8.
There's a program called Paradigm that has built-in support for Self-Paced Reading, it also handles Arabic characters. You'll just type in your sentences and then use back-slashes to specify each segment. For example:
The actress\shot\the officer\who\was standing\on the balcony
Paradigm will log a timestamp for the onset of each segment (in Excel) so it's pretty easy to analyze.
Here's their website:
