The table at left fills up as the experiment is proceeding,

The M columns with the Medium Threshold values.
The H columns with the High Threshold values.
The R column shows the subject responses.
The I column shows the Reinforcement Threshold (High or Medium) and Amplitude.

The subject calls out its responses and the investigator enters them through the keyboard.
The numeric values 1, 2, 3, or 4 must be followed by the Return key to validate the response.

Click on the "Edit" and "View" submenus below, to see the corresponding editable and display windows.



Escape with Blocks

Added Features:
  1. Blocks - The numbers of high and medium intensity stimuli are forced to be equal in each block, thus preventing one type to be presented too many times in a row. Notice that using a "Block Count" of "1" and a "Block Size" of 20 is the same as using the version without the "Block" feature and a "Session" "Stimulus Count Limit" of 20.
  2. Chart Auto Scroll - The chart is automatically scrolled to the end of the data each time a line is added so that the last data entry is always visible.
  3. Preferences - What was named "Defaults" is now named "Preferences".
  4. Weighted Random - What was named "Pseudo Random" is now named "Weighted Random".
  5. Mouse as Input Device - The mouse left and right buttons can now be used instead of the keypad No.1 and 2 respectively.
  6. "Done" button alternative - when the "Edit Subject Info" is selected, the time stamp in the filename is automatically updated. Clicking the button a second time is the same as clicking the "Done" button on the form.
    The same applies to the "Edit Preferences" button.
