2 forced choice 0/1-back task with experience sampling

Two Force Choice N-back Paradigm

Based on the task developed by Konish et al., I am working on a enhanced verison of the task. The task uses a n-back memory paradigm intending to induce mind-wandering.

Dependency

The current version was tested on: Python 3.7.5 Psychopy 2020.2.4post1

Running the task

Execute run.py through commend line: python run.py

Modifying the length of the experiment

Currently the experiment length, probe number, condition order are set through files in parameters and module datastructure. The content of parameters/ConditionsSpecifications_ES.csv determine the condition switching structure. The current file populate a design of two blocks, starting with a zero-back block, and two type of go trials. Please see example_trial_generator.py for details related to the module datastructure.

Modifying experience sampling questions

Change the questions/scales/lable in stimuli/ES_questions.csv. Please leave the headers untouch.

Modifying instructions

'#' is used as page breaker. The text in between curly breackates {} changes in the experiment. Please do not modify the text inside the breakets.

Modifying MRI related setting

This script supports the buttom boxes set-up in York Neuroimaging Centre. The two buttom boxes are mapped to number 1 to 4 and 6 to 9 on a regular keyboard. Number 5 is linked to MRI trigger setting.

If your neuroimaging centre uses the same set up, there's no need to modify the code. If you use parallel port, please contact your local support to find out the setting and modify the code yourself.

The dummy volumes are accounted for in the scanner used at York. If you require manual set up, please modify the variable in run.py accordingly. Or write a parallel port module fitting your own setup to map respond buttons to key 1 to 9. (Highly recommended.)

nbackexpsampling's Issues

Code Crashes

Hello, I have a problem of running the code. It crashed after a couple of non-target trials presented, besides I couldn't use the keyboard to skip the instruction but the key "Enter" worked. The output showed "Experiment ended with exit code 1 [pid:11916]".

data structure module

Currently, this is a dumpster fire.
The module input and organisation are both too complicated.
Need to rethink and simplify the structure and add test.

Code Crashes

I have downloaded the code and attempted to use it in the latest version of Psychopy (2020.2.10). When I run the code it opens the instructions and when I press '1' to continue it crashes.
