jsPsych Tutorial - Setting up a Cognitive Science Experiment with Mixed Design and Instruction Test

This is a jsPsych tutorial on creating a cognitive science experiment with between and within-subject factors, and an instruction test that needs to be passed before subjects can proceed to the next phase of the experiment.

The experiment is a causal inference experiment with a 2 (observed sample size: small vs. large; between subjects) x 2 (observed effect size: small vs. large; within-subject in random order) design. An additional counterbalancing factor is "orientation of the rating scale".
