ResumoAttention is drawn to some causes of distancing between fluid and crystallized intelligence through detailed testing, environmental observations and responses of 210 children, their families and teachers. High Gc children (with IQ scores of 141+) were associated with educationally-superior home backgrounds, but not with abnormal emotional or personality features. High Gf children (99th% Raven's scorers) were found to reflect specifically the Cultural Milieu and Achievement-Related Facilities of their homes in their high IQ scores, but where Gf was insufficiently provided with opportunity, Gc appeared to suffer. Calculated proportions of fluid and crystallized intelligence in high IQ were varied, the scores becoming more heavily loaded with environmental influences towards the top of the scale, being 26% for children of exceptionally-high Gf and 13% for those of average to high Gf. It is suggested that where an IQ test is used, a cut-off point of IQ 130 be taken for the identification of intellectually-gifted children, along with verbal and other specific-ability tests.
