nested loops

DahmSF

Dear forum,

i trying to build up my first 'drag and drop' experiment with the intention not to use any inline_scripting.

The idea is to learn my children how to type with ten fingers.

That's the task:

Level 1: 4 letters (fgjk)

Level 2: 6 letters (sdfjkl)

etc.

I managed to set up level 1. Now i could copy this and change the necessary for Level 2. But that's not effective considering that i will want to make much more levels.

So i thought about setting a nested loop in front of Level 1 that changes the target letters.

What's in Level 1?

A loop with the 4 letters (random, 5 repetitions)

Basically a sequence in the loop: stim of letter, response, feedback (individualized with our own sounds :) )

My question: How do i have to set the variables within the loop to manage that?

I thought about something like:

One Loop: var1 (fgjk), var2 (fgjkslsl)

The LevelLoop than actually draws from one of the variables in the other loop by using var1 or var2.

Cheers,

Stephan

Managed it myself :)

Is it possible to get the median response time instead of avg_rt? (RTs are usually not normally distributed)

I mean without inline_scripting.

Not without any scripting at all. But you could include a Python expression directly in, say, a feedback item. And then you could make use of the responses object, like so:

• https://osdoc.cogsci.nl/3.3/manual/python/responses/
• https://osdoc.cogsci.nl/3.3/manual/stimuli/text/#variables-and-inline-python

[=np.median(\[resp.response_time for resp in responses if resp.feedback\])]

This does require a very minimal inline_script with import numpy as np , though.

And I saw that you were answering some questions on the forum. Thanks for that!

Cheers!
