Normative studies of the Polish adaptation of Th e Ruff Figural Fluency Test (RFFT) were conducted on 475 men and women aged 16-79, taking into consideration such factors as gender, education, and place of residence. Clinical studies were also performed on a group of patients with left -, right-, or bilateral hemispheric brain lesions, Parkinson’s disease, Huntingon’s disease, progressive obturational lung disease, dementia and depression. Th e results support the utility of the RFFT as a measure of executive functions. Th e validity and reliability indices of the Polish version of the test are similar to those reported by Ruff (1996). However, the sample Polish test performance differs notably from American samples performance and this difference is discussed.
