Developing automaticity and speed of lexical access: the effects of incidental and explicit teaching approaches

There is general agreement that speed of lexical access is an essential component for successful communication and fluent language use. In vocabulary acquisition research the majority of studies have focused on the acquisition of the form and meaning of new words but research into the teaching conditions leading to the improvement of speed of lexical access is still scarce. This article reports results of two studies which explored the effectiveness of two vocabulary teaching approaches for the development of speed and automaticity of lexical access by learners of Spanish as a foreign language. Participants in Study 1 were exposed to the target vocabulary in reading passages (incidental approach), while participants in Study 2 were exposed to the target words in explicit vocabulary activities (explicit approach). A pre- and post-treatment lexical decision task assessed participants’ speed of lexical access. Two indicators of improved lexical access were examined: faster reaction times (RTs) and a decrease...
