Table 4. Tests of fixed effects for LMEM of cortical tracking across data type (real r values, random permutation r values), frequency band (delta, theta or alpha) and age (4-, 7- or 11-months).
Results reported for separate LMEMs run on the first half, second half and full sample of data. Significant results (p<0.05) denoted by bold italic text. The Satterthwaite approximation was applied to approximate the degrees of freedom, due to the missing cases.
