Repeated Measures text based experiment

Do you want it to also run online? (y)

What are you trying to achieve?:

This is my first time using PsychoPy and I’m looking for some advice before I get started

I am designing a study that has 4 different types of blocks (pos-pos, neg-neg, pos-neg, neg-pos).

Each block consists of 4 sentences. The first 3 sentences of each block are presented 1 entire sentence at a time (e.g. “The cow jumped over the moon”) separated by a fixation cross. The final sentence is presented one word at a time, with fixation crosses between each word (e.g. “I” + “have” + “gone” + “fishing”).

After the final sentence of each block participants will respond to 2 questions using a slider.

The study will consist of between 80 - 120 blocks (undecided). Each block will contain entirely unique sentences (i.e., each sentence is presented once and only once per participant). The specific sentences, and their order, will be fixed within blocks, but the order of the blocks should be randomized between participants. So Block 1 for participant 5 could be Block 62 for participant 10. But if block 1 p5 = block 62 p10 then the sentences (and their order) will match.

For the first 3 sentences participants can advance at their own pace, for the final sentence each word / fixation cross is presented for a fixed time interval (I don’t need any advice with regards to this).

What I am specifically looking for advice on is the best and most efficient way to set this up.

Should I be using the text feature to input each sentence (and each word for the 4th sentence of each block)? This seems like the simplest solution, but perhaps a bit time consuming. Is there a more efficient way to do this?

Any advice before I jump in is appreciated.

Hi there,

Thanks for posting on the forum, and welcome to the PsychoPy community!

To help illustrate how you might set this up, I’ve created a demo experiment you can try out:

:backhand_index_pointing_right: Download all the files here

On the GitLab page, scroll to the bottom to find the README section, which explains how the task is set up and how you can adapt it for your study.

One thing you’ll likely want to update is the content of the BlockX-trials spreadsheets — for the demo I’ve used the same example sentences across all blocks, just to keep it simple.

I hope this gives you a good starting point for building your experiment in PsychoPy!

Best,
Becca

Thank you very much!

It looks like there is an issue with the link to download the files - it returns a 404 page not found error
