Template: Stroop Paradigm with Feedback
Stroop Effect with Feedback

Required Experiment Builder Version: 1.4.55 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Medium

This example illustrates:
  • How to use Accumulators and AddToAccumulators Action nodes
  • How to display RTs data from one block of trials with Accumulators

This example adds these additional features to the Stroop Effect example built into SR Research Experiment Builder (File -> Examples -> Stroop): 
  1. After each trial, participants' performance, such as the Reaction Time (RT), Experiment Condition Type of the trial, whether or not the correct keyboard key has been pressed are reported on the display screen; 
  2. After each block of trials, statistical data of participants' performance (e.g., the averaged RT) is reported on the display screen.
**Additional detailed information about the project is given in the notes section for most nodes. To see notes for a given node, either mouse over that node or click on it to display the notes window. If the notes window is not visible, go to the "View" drop down menu in Experiment Builder, select "Properties", and check "Note".
