Mean and standard deviation are given for each of the three groups separately as mean(stdev)

T scores and Age equivalent scores are taken from the Mullen Scales of Early Learning

Composite score reflects the composite of the 4 subtests of the Mullen: Visual Reception, Fine Motor, Receptive and Expressive Language. The standardized mean is 100
