| Abstract: | The Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Stanford‐Binet Intelligence Scale–Fourth Edition (SB‐IV), were administered to 20 gifted children and 20 non‐gifted children to examine the extent of the difference in IQ scores obtained on the two tests and whether order effects were present. Results show that the SB‐IV Composite Score was significantly higher than the WISC‐III Full Scale IQ for both groups. However, for the gifted group, unlike the non‐gifted group, this difference achieved significance only when the SB‐IV was administered first. When either IQ test was administered to the gifted students for the first time, without the confound of a learning influence, there was no significant difference in mean scores. However, when both tests were administered, it was found that the SB‐IV influenced the WISC‐III Full Scale IQ in a downward direction whereas the WISC‐III influenced the SB‐IV Composite Score in an upward direction. © 2002 Wiley Periodicals, Inc. |
