“…Evidence comes from several domains. It has been known for some time that correlations between juvenile and adult IQ increase throughout childhood (Anderson, 1939;Honzik, McFarlane & Allen, 1948), as do correlations between child and parent IQ (Honzik, 1957) and between consecutive testings in childhood (Humphreys & Davey, 1988;Wilson, 1987). Whether increases in the stability of intelligence continue throughout adulthood has been studied less intensively, but the trend does seem to continue, albeit at a decelerated pace (Schuerger & Witt, 1989).…”

“…First, the reduction in degrees of freedom was sizable in the IQ analyses, reducing the power to detect differences; in addition, the Early Single group was reduced by six subjects, or by 18%. Second, IQ scores have demonstrated situation effects in other research (e.g., Honzik, MacFarlane, & Allen, 1948). Because the IQ data were obtained after a school change for the Double and Early Single groups, any effects suppressing functioning may have also affected IQ test performance.…”

“…IQ measures are often regarded as meeting this requirement. However, Honzik, Macfarlane, and Allen (1948), in a study which repeatedly tested children between the ages of 6 and 18, found that over half the children showed IQ variation of 15 or more points. More recently, Rosenbaum (1976) reports considerable changes in IQ for some students during the high school years.…”
