Skinner pioneered the free operant technique, where organisms could respond at any time during a protracted experimental session.

Using the battery as a buffer, MARES will consume an average of 150-200 W during a typical experimental session.

In 1989, Wellford conducted twelve experimental sessions each conducted with five participants over thirty periods simulating the stable and unstable cases.

In this experimental session, no discrete stimulus is used to signal the occurrence of the aversive stimulus.

Then participants were asked to keep a diary on their memory process between two one- hour experimental sessions.

The experimental sessions were conducted in an indoor part of the ape's cage, initially with both Abang and Dayang present.

In 2008, the Oregon Legislative Assembly held an experimental session, to explore the possibility of holding annual sessions as a regular practice.

Not a major expense, but not chickenfeed either, for one experimental session.

The experiment consisted of a practice session (24 trials) and an experimental session (120 trials).

The children had never met prior to these experimental sessions.
