Se. Fernaeus et O. Almkvist, WORD PRODUCTION - DISSOCIATION OF 2 RETRIEVAL MODES OF SEMANTIC MEMORY ACROSS TIME, Neuropsychology, development, and cognition. Section A, Journal of clinical and experimental neuropsychology, 20(2), 1998, pp. 137-143
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.
