Sternburg Search Paradigm

Required Experiment Builder Version: 1.4.402 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Easy

This example illustrates:

• How to use the Randomization Settings to group different Data Source rows
  
• Basic use of Conditional nodes to check task performance
  

Description:

The experiment is implemented based on the Experiment 1 described by Sternberg (1966) in the following paper:

• Sternberg, S. (1966). High Speed Scanning in Human Memory. Science 153, 652-654.
  

In every trial, a symbol of digits with a random length of from 1 to 6 is shown one digit at a time with a 1.2 second interval between them. Followed by a beep, a test digit is shown and a response is required. After the response is made, a feedback message is shown. The experiment consists of totally 168 trials: 24 practice and 144 experiment trials. The results are recorded in the RESULTS_FILE.txt.

This project sheds light on Experiment Builder's capabilities in randomized design and accurate control of time interval (1.2 seconds). A quick understanding of the project may become possible by reading the annotation note for each component in it.

**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 Sternberg_Search.ebz example from this message.
   
2. Launch the Experiment Builder application.
   
3. Unpack the Sternberg_Search.ebz file to a location on your Experiment Builder PC with "File -> Unpack".
   
4. Open the project in Experiment Builder.
   
5. Deploy the project to a new folder.
   
6. Run the Sternberg_Search.exe from the deployed directory.
