Required Experiment Builder Version: 2.3.38 or higher
EyeLink Required: Yes
Type: Complete Example

This example illustrates:

• How to use Custom Class node
  
• How to call "do_staircase" method in the Custom Class to check the participant's accuracy and adjusts the ISI
  

Description:

This example (based on the Up / Down Method example) illustrates using a Custom Class to perform an Up / Down (or Staircase) method. This Up / Down method is used to find out a threshold at which the participant cannot make a reliable response to the prime direction with an arrow / neutral mask. You may need to adjust the refresh rate (default is 60 Hz).
