Previous studies examining the repeatability of the mfERG have typically used ring averages to look at the differences between different sessions.
Bills to create a National Park there were introduced and failed in five different sessions of Congress between World War I and World War II.
64 subjects attending three different sessions of 30 min each, filled in a special questionnaire during the experiments.
There were no differences between the different sessions showing no effect of Scenario, also, there was no significant effect from long-term interaction either, although there was a small trend that participants rated the agent as easier to use in the later sessions.
The ambient light levels (a typical office illumination) were maintained constant between the different sessions.
The subjects had a 5 10 minute-long rest between the different sessions.
The sequence of the 4 exercises was randomized using lottery, and then distributed among the 2 sessions (2 in each session), with at least two days in between the different sessions.
It stands to reason that there should be another album's worth of this material, which flickers back and forth between different kinds of sessions and ideas, some quite elegant, some deeply boring, none of it very well edited.
A comparison between two groups of students from different sessions was also made.
Several subjects participated to different sessions but with a gap of at least one week between 2 experimental sessions.
