Correlational patterns in semantic and phonological fluency in school aged children

Abstract

Semantic verbal fluency tasks (SVF) and phonological verbal fluency tasks (PVF) are highly sensitive measures used to detect and diagnose different pathologies in adult and child populations. The results of numerous investigations point out differential performances between these two tasks both in adults and children. Based on this evidence, we intend to identify the possible connections between SVF and PVF in a group of Argentinian children aged 8 to 12 years old who attended to 3 rd , 5 th and 7 th school primary levels. Participants answered to a SVF task which tested five categories (animals and body parts for living things and transports, cloth and musical instruments for inanimate objects domain) and a PVF task where the phonemes /f, a, s/ were assessed. A correlations analysis was carried out. The result showed there is a mild association between both tasks. In addition, an exploratory factor analysis and a confirmatory factor analysis were conducted. Two differential factors were detected: a semantic verbal factor and a phonological verbal factor. Our results show that phonological and semantic are different processes and function separately in early development, although due to their correlation it is possible to conclude that both processes converge in the same store in verbal memory.
