Talk:1/f noise
From Scholarpedia
In the Section on "1/f noise in the brain", I suggest the authors mentioning more recent research on long range correlations on human brain oscillations (e.g., K Linkenkaer-Hansen, VV Nikouline, JM Palva, RJ Ilmoniemi - Journal of Neuroscience, 2001, 21(4): 1370-1377), which studied 1/f like phenomenon in the amplitude variations of brain oscillations. Similarly, in the Section on "Music, time perception, memory, and reaction times", I suggest the authors mentioning the research work on long memory processes on human timing errors during rhytmic synchronization and syncopation task (i.e., Long Memory Processes (1/f^{α} Type) in Human Coordination,Y Chen, M Ding, JAS Kelso - Physical Review Letters, 1997 (79): 4501-4504; Origins of timing errors in human sensorimotor coordination, Chen Y, Ding M, Kelso JA - J Mot Behav. 2001 Mar;33(1):3-8), both of which I think are relevant to the 1/f phenomenon in human time perception.
In the section on "identifying 1/f noise", maybe the authors can decribe some other empirical methods for identifying 1/f noise, such as Rescaled-Range or Hurst analysis etc., other than the usual power spectrum analysis. Because there can be cases where improper time series techniques such as detrending were applied before a simple power spectrum analysis, the resulting time series might appear to be 1/f-like simply because the non-stantionary trend from a more trivial random walk (1/f^2) were removed by detrending. This especially could happen for short time series such as those from human experiments (e.g., Gilden, Thornton, and Mallon, 1995, Science, 267:1837-1839).
