Abstract:
Three groups of Ss, exposed to 1.4, or 7 days of sensory deprivation darkness and silence, all showed a significant post-isolation decrease in occipital alpha frequency. However, no indication of a progressive decrease in mean alpha frequency as a function of increasing duration of sensory deprivation was obtained, a finding contrary to that reported in several earlier studies employing a longitudinal approach. After each of the three durations, the magnitude of the post-isolation decrease was approximately 1 Hz. It was concluded that a different temporal pattern of EEG changes may occur, depending on whether a cross-sectional or longitudinal test procedure is employed. Author
