Moreover, subjects who were in the high vigilance stage A during the presentation and reproduction phase might have tapped faster owing to an accelerated internal clock.
Assuming that the vigilance stage during the presentation of the auditory rhythm is similar to the vigilance stage during the tapping phase, our results are consistent with the outcome of several studies examining the impact of arousal on time perception.
The re-tapping-length was significantly shorter (t(17) = −2.190, p < 0.05) for reproduction phases following high EEG-vigilance stage A compared to the lower EEG-vigilance stage B. These findings support the hypothesis of a varying time perception and of speed alterations of the internal clock after different states of EEG-vigilance, which were automatically classified by VIGALL.
Lambs spent in average one third of test duration in vigilance postures during arena test phase 1. Proximity to flock-mates and the human in arena test phase 2 was in average 27 s, which is approximately 2.2 fold lower than the maximum proximity duration (60 s).
Therapy for PE is more rigorously monitored, and the increased clinical vigilance in the initial treatment phase explains the reluctance for ambulatory treatment.
To divide vigilance between presentation and tapping phase, subjects were further briefed to engage in stretching as a short activity after presentation of an acoustic signal to enhance alertness.
Moreover, HPV infection can interfere with the local immune vigilance mechanism both in the induction phase (antigen presentation) and in the effector phase (generation of antibody-producing B cell and cytotoxic T cell) [ 10].
4 Other potentially relevant benefits that have been reported include decreased severity and duration of ictal or postictal phases, and improved mood, vigilance, communication, cognition, and possibility of reducing antiepileptic drugs (AEDs) and associated adverse effects.
We found significant reductions in rapid eye movement sleep (REMS) during the light phase in both females and males, and significant increases in numbers of vigilance state transitions during the early dark phase in females but not in males.
Sri Lankan media later reported the Defence Secretary as saying that "the modern 'community police' concept was introduced to Sri Lanka as CDCs [which] were used effectively particularly during the final phase of the war to enhance vigilance among communities".
