Empathy Essay

Empathy-Maze Commands from Noldus EthoVision

Type Action Command Examples
Shock Start c=1,2,0 (1 left chamber, 2 right chamber, 0 both chambers)
v=1-100 volume
d=1-360 duration in seconds
f=200-18000 frequency
i=0.1–4.0 shock current level (mA)
c=1,v=50,d=5,f=1000,i=0.5
c=2,v=50,d=5,f=1000,i=0.4
Shock Stop t=0

Empathy Result

Once the adapter receives the command, a random shock schedule is generated based on the algorithm described in Random Shock Methods.pdf. The shock schedule is then executed.

There are two ways to stop the shock execution:

  • Send a stop command from video tracking
  • Go to the Command Execution tab, choose command t=0, and click the Send button

Save Shock Schedule

There is no result output for the empathy test; behavior is captured and analyzed with video. To save the shock schedule, the grid data can be copied and pasted to a spreadsheet.

  1. To select the entire grid, select the first row and first column cell, hold the Shift key, then select the last row and last column cell. The entire grid data should be selected (highlighted in light blue). Release the Shift key after selection.
  2. Press Ctrl + C to copy the data to the clipboard.
  3. Go to a spreadsheet page and press Ctrl + V to paste the data. The grid data along with headers will be pasted into the spreadsheet.

Manual Commands

For testing purposes, the software allows the user to send a shock command (a connection must be established).
