Plus, Le adds, "we provide two pieces of information – both the fixed time schedule and the real-time departure information".
We avoided establishing a fixed time schedule and provided people with contexts where they could talk freely.
Therefore, the present study examined the effects of intracerebroventricularly administered galanin (5.0 20.0 μl/5 μl) on free water consumption during a 10 min test session and a follow up open field exploration, an operant progressive ratio (PR) schedule, a test used to assess reinforcer strength, and an operant fixed time schedule (FT 20) in 23.5 h water restricted rats.
FT: fixed time schedule of reinforcement.
No fixed time schedule was used though but patients were retreated whenever they requested it.
On day 2, they were tested under a fixed time schedule of reinforcement in which one food pellet was delivered every 60s in a non-contingent manner for 30 min. On day 3 of training, the left lever was inserted into the box, and every press resulted in the delivery of a food pellet.
Attempts to reduce the expenses for HBIG treatment in the past include lower HBIG doses, HBIG administration by the intramuscular rather than the intravenous route, or tailored HBIG administration guided by plasma concentrations rather according to a fixed time schedule [ 2].
Blocks were dispersed across the day at random, or using a fixed time interval schedule.
All animals received next two sessions of magazine training (days 3 and 4) in which 20 deliveries of a single 45 mg sucrose pellet (Formula F; P.J. Noyes Co., Lancaster, PA) were freely given on a fixed time (FT), 1 min schedule of reinforcement.
Depending on the experimental design, at least one practice session should be scheduled at a fixed time interval (e.g. one week prior to the first experimental session) prior to the experiment to reduce learning effects.
