Abstract
To identify components that contribute to word-fluency performance, 12 6 patients referred to a Memory Clinic for suspected cognitive impairm ent underwent a neuropsychological examination including the Controlle d Oral Word Association test (FAS; Benton & Hamsher, 1976). The number of words produced in the FAS test during six consecutive 10-s periods followed a negatively accelerated curve approaching an asymptotic lev el after about 30 s. The Is FAS variables (3 letters x 6 periods) were entered into an exploratory factor analysis resulting in two factors. One factor, linked to a semiautomatic and rapid retrieval from semant ic memory, loaded on the initial phase of the FAS test. A second facto r, linked to an effortful and slow retrieval from semantic memory, loa ded on the later phase of the FAS test. Thus, two retrieval modes of s emantic memory contribute differently to the initial and later part of the FAS test, which may have theoretical and practical implications.
