AnnotationThis study examined whether the lexical inhibition underlying neighbourhood effects on visual word recognition is changed with ageing. To do so, orthographic neighbourhood frequency was manipulated for French words that had either no higher frequency neighbour (e.g. taupe) or at least one higher frequency neighbour (e.g. the word loupe has two higher frequency neighbours, coupe and soupe). Native French speakers, 27 young adults (mean age 20.9) and 27 older people (mean age 77.8) performed a lexical decision task with 64 five-letter words from the French lexical database BRULEX. An interaction was found between age group and orthographic neighbourhood frequency or word latencies. More precisely, an inhibitory neighbourhood frequency effect (NFE) was observed for young adults, but not for the older ones. These data are consistent with the assumption of an age-related decline in lexical inhibition and activation. The findings are discussed in the framework of visual word recognition and ageing. (RH).
