Maturation of EEG power spectra in early adolescence

By Hudspeth, William J.; Pribram, Karl H.

H. T. Epstein (see PA, Vol 52:9783 and 1986), R. B. McCall (see record 1988-32308-001), and R. B. McCall et al (see record 1984-17419-001) presented discrepant findings regarding the presence of stages in brain and cognitive maturation, as described in Piagetian theory. This article questions whether their variables (e.g., skull circumference and global mental test scores) are appropriate indices from which to make such conclusions.
