The Experiment Factory robots are a set of scripts (and associated containers) that provide an automated means to run through a set of experiments or surveys. For example, to specify a default inter-trial interval, a minimum valid response time duration, and a maximum width for all of the experiment's page content, the object would contain:. How can I change properties of the stimulus dynamically? 10. In jsPsych this means that we add a trial, which consists of a single question of which we read the response into the ppn variable, which will be used later. Figure 1 shows the demos/stroop page visible to its owner. Of course you can write this all yourself, but you could also use a framework for this.
