Abstract
Normative and reliability data for the Excluded Letter Fluency (ELF) Test are provided. A stratified random sample of 399 healthy young adults aged 18 to 34 years from Sydney, Australia, completed the ELF Test as well as a full-length WAIS-R, as part of a larger battery of tests. After a 1-year interval 99 of these individuals were retested on the same forms of the tests. The influence of age, sex and education was investigated on the ELF and only education was found to have a significant overall effect on the total scores. However, gender was found to have an effect on the error scores, with males making more rule-breaks than females. Tables are provided for converting ELF raw scores, corrected for years of education, to standard scores with 90% and 95% confidence intervals for both test and retest purposes. A table for calculating the base rate of errors, for males and for females, on the ELF is also provided.
