Lichten, William – Developmental Review, 2004
The law of intelligence is presented in test independent form. Mental abilities, physical brain size, and infant motor capacity follow the same law of growth from birth to adolescence. Mental growth is independent of race, "SES" or the Flynn effect. The vitality of the mental age scale calls for a reexamination of Wechsler's deviation IQ. This…

Mayes Motor-Free Compilation (MMFC) for Assessing Mental Ability in Children with Physical Impairments.
Peer reviewed Peer reviewed
Mayes, Susan Dickerson – International Journal of Disability, Development and Education, 1999
The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…

Concurrent Validity of the Mayes Motor-Free Compilation (MMFC) for Assessing Mental Ability in Children with Physical Impairments.
Peer reviewed Peer reviewed
Pelco, Lynn E.; Sarpolis, Deborah L. – International Journal of Disability, Development and Education, 1999
This study investigated the concurrent validity of the Mayes Motor Free Compilation (MMFC) using the mental scale of the Bayley Scales of Infant Development (BSID) as the criterion variable with 50 typically developing preschool-aged children. Results indicated that the MMFC and the BSID scores were significantly and positively correlated.…
