Function
A “Serial Choice – Collection” stage is specifically designed to perform the “Wait For Collection”
function in the five-choice serial reaction-time task.
The stage sets the state of the operant chamber, (normally just the house light), then waits for a
response in any sensor. Normally there is no timeout associated with this stage, the protocol pauses
indefinitely until the subject makes some form of response.
The “Serial Choice – Collection” stage automatically assigns all “nosepoke” sensors in the chamber as
“Dummy” resources, i.e. all the niche sensors. A response in any niche during the “Wait For Collection”
stage is normally considered a “perseverative” response”, i.e. a repeated response to the stimulus. A
five choice paradigm normally sends the protocol into a timeout state as a result of a perseverative
response.
The developer normally assigns the sensor in the pellet receptacle as the “target” resource. Activation
of the target resource triggers the “Exit On Target” endpoint. Activation of any dummy resource
triggers the “Exit On Dummy” endpoint.
