Woof.
For use with dogs, in apparatus that has an omnidirectional lever (an on/off device triggered whenever the dog pushes a stick in any direction).
The lever can be used to initiate trials in a variety of tasks. This is configured within each task, not in the General Parameters.
From the program's point of view, the dog lever is indistinguishable from the monkey lever (i.e. it's simply an on/off lever as far as the program is concerned, and is referred to as LEVER in the Required Devices).
In general, when a lever-press is required to start a trial:
| • | the houselight is on throughout a task and is not switched off during the ITI (unless the previous trial was failed and the punishment includes darkness) |
| • | lever activations are required to start each trial, rather than to start the task as a whole |
| • | the Marker 1 sound (where used), which previously indicated the start of the trial, will indicate the opportunity to press a lever to start the trial |
| • | when the lever is activated, the trial begins immediately |
| • | if the lever is already being held "on" when a lever response is required, the program waits until it's released and activated again. |
| • | if the session time limit elapses while the program is waiting for a lever-press, the program will wait for the current trial to be initiated and completed, and will then finish. |
