The first figure shows the generation phase of a large scale separation which occurs irregularly and aperiodically
. This schematic is drawn according to Fig.12, which is a result of the flow visualization test at a moment of the transition.
The Assessor is an RtUnit which may run its job either periodically, at every predefined period, or aperiodically
after every adaptation loop execution.
They vibrate aperiodically
(irregularly), often at two different frequencies, or with very sudden and transient changes in frequency.
Each VI schedule specified that food became available aperiodically
, with the average time between successive food availabilities equal to the schedule value (e.g., 60 s under a VI 60-s schedule), and was delivered dependent on a keypeck response.
Compared with the number of distractors, targets occurred aperiodically
and without forewarnings.
