In fixed-interval (FI) and response-initiated fixed-interval (RIFI) schedules of reinforcement, a response is required after an interval has elapsed for delivery of reinforcement. In RIFI schedules, a response is required to initiate each interval as well. The objective of this experiment was ...
A hustle-and-bustle scene was seen in the customs supervision area of the Huaihua International Land Port on the morning of December 31, 2024.Freight train X9689 pulled out of the Huaihua West Marshalling Station at 3:00 on the morning of January 1. It was the first fixed-schedule China-...
Recent experiments have demonstrated that the characteristic pattern of responding engendered by a fixed-interval (FI) schedule of food reinforcement can also be established and maintained by response-contingent electric shocks. Under an FI schedule of food presentation, the characteristic pattern of respo...
The terminal links consisted of a variable-interval or an arithmetically equivalent fixed-interval schedule. For half the subjects a brief response-independent change in key color signaled reinforcement. This procedure eliminated the differences in predictability of reinforcement between the two terminal ...
Ten rats were submitted to chained fixed-ratio (FR), fixed-interval (FI) schedules of reinforcement. A FR schedule at one lever produced a discriminative stimulus associated with a FI 60-s schedule of primary reinforcement (water) at the second response lever. In Experiment 1, the FI schedule...

In the SRT, single instructionszout of an instruction setZare presented sequentially. We told participants to press the corresponding key as soon as a new instruction appears. The subsequent instruction shows up in a fixed interval after a participant’s completion of the previous trial. The mod...
Each replication group has a separate, fixed replication schedule that determines how frequently changes to the data in the group is replicated to other sites. For example, a configuration change to a role-based administration configuration replicates quickly to other sites to ensure that these ...
Access to the training chamber was controlled by motorized gates, and mice were allowed to enter the training chamber based on a fixed, regular schedule of 15 min training every two hours (Figs. 1 and 2; Methods). The mice were kept on 12-h light/dark cycle, with light phase starting ...
schedule a single function call with two parameters. The last time I had to do something like this, I believe I had to capture approximately eight variables, and capturing and setting all this state becomes quite tedious and prone to error. If I recall correctly, I found and fixed at ...
