Abstract
In this paper a discussion and re-analysis of experimental
data is carried out. The data consist of measurements of the
performance on two tasks (verbal and spatial) that are performed
by the two different brain halves. The original experiments
and analysis had been conducted by R. Klein and R. Armitage
in the investigation of ultradian rhythms in humans. The
period of the ultradian cycle had been hypothetically equated
to the period of REM-sleep occurrence. In the re-analysis,
previously unmentioned inhomogeneity was discovered and the
findings by the original experimenter-analysts could not be
confirmed at the stated significance levels. A discussion of
and recommendations for the experimental set-up are included.
The re-analysis was conducted with non-parametric methods.
Small ultradian rhythmicity was concluded to have been induced
by influence of circadian rhythm, experimental set-up and
inhomogeneity among subjects.
