Create self-paced reading experiments

Niu

Hi everyone,

I'm trying to use OpenSesame to create an self-paced reading experiment. I want it to show one word each time, and I need to collect rection times of each word.

For example:

The

cat

that

...

I attempted to create a sequence including several 'sketchpads' and 'keyboard_responses' , but I noticed the sentences are in different lengths, so it doesn't work very well. For example, I have some sentences with 10 words, and some with 8 words. In order to accommodate the 10-word sentences, I need to create 10 sketchpads. But for 8-word senteces, it will be 2 blank sketchpads.

Does anyone have any ideas about how to solve it?

Many thanks!

Hi,

You can set the run if fields of the last items (9 and 10), to only run if the sentence length is 10 words. That means that you have a variable that indicates the length of a sentence.

Does this make sense?

Hi Eduard,

Thanks a lot for your help!!! It's really helpful!

But may I ask how to set run if condition? And I'm also not quite sure about how to set the variable. I did following changes, but it didn't work very well. Do you have some suggestions about it?

Thanks a lot indeed!

Best wishes

Hi Niu,

you started the right way (as I can see from your last screenshot, where you put `[s9]=1`). This is how you change the run if field. What you need to do to make your experiment work is adding a variable to the loop table that indicates how many words a sentence has and assign value saccording to its length (e.g. variable sentence_length could have the value 8 if there are 8 words in that sentence). Now, you can put in the run if field something like this: `[sentence_length]>8` for the 9th and 10th word.

Does that make sense?

Hi Niu,

I am creating a self-paced listening task and I am having the same problem as you had. How did you managed to solve it? I put a variable in the loop table for sentece length and I changed the run if condition but it seems it doesn't work.

Thank you !

Hi Ioli,

Can you provide more details on what you did? maybe providing screenshots and/or uploading the experiment.

Thanks,

Eduard
