Welcome to the words-in-noise-EEG wiki

DecLearn Objects mTurk is web version of the DecLearn Objects paradigm. This paradigm was originally written in ePrime by members of the Brain and Language Lab at Georgetown University. [Katie Schuler](mailto: [email protected]) has re-programed this experiment in JavaScript so that data collection can be conducted over the web on Mechanical Turk.

This new version of the experiment relies heavily on jspsych, a JavaScript library for behavioral experiments and psiTurk, a toolbox for running dynamic web-experiments on Mechanical Turk. If you use this program (or a modified version of it), please make sure to cite the nice people who makes these tools in your published works.

Basic structure of the experiment

The basic structure of the experiment is fixed and cannot be modified without modifying the underlying experiment JavaScript code. Click the link below to the see a detailed overview of this structure.

Customize the experiment

Although the basic structure of the experiment is fixed, there are a number of parameters that can (and should) be customized via a parameter text file, param.yaml. Before running DecLearn Objects on Mechanical Turk, you'll want to set the parameters of your experiment (e.g. timing, feedback, stimuli) and test these changes on your local computer.
