Simon Effect

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

This example illustrates:

• Use ASIO audio driver for precise sound timing.
  
• Use Accumulator to store RT times from the four different task conditions.
  

Description:

This example is an implementation of the Simon Effect experiment described in the following paper:

• Simon, J. R. (1969). Reactions toward the source of stimulation. Journal of Experimental Psychology, 81, 174-176.
  

There are 2 blocks of 50 trials, each block corresponding to the Toward or Away task. After each trial a report is shown on the display screen summarizing participant performance. At the end of the experiment, response time is reported as a function of direction of response (Towards vs. Away) and key press (Left vs. Right).

Two versions, DirectX and ASIO audio driver of the implementation, are provided. It is recommended that the ASIO version be used for precise audio timing.

**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".

Instructions:

1. Download the SimonEffect_ASIO.ebz or SimonEffect_DirectX.ebz example from this message.
   
2. Launch the Experiment Builder application.
   
3. Unpack the SimonEffect_ASIO.ebz or SimonEffect_DirectX.ebz file to a location on your Experiment Builder PC with "File menu -> Unpack".
