Description
Summary:•Evidence shows interaction between vowel fronting/backing and directional hand movements.•The present study shows that the same effect can be also observed in relation to directional leg movements.•Direction of tongue, hand and leg movements is planned in partially overlapping processes. It has been shown recently that when participants are required to pronounce a vowel at the same time with the hand movement, the vocal and manual responses are facilitated when a front vowel is produced with forward-directed hand movements and a back vowel is produced with backward-directed hand movements. This finding suggests a coupling between spatial programing of articulatory tongue movements and hand movements. The present study revealed that the same effect can be also observed in relation to directional leg movements. The study suggests that the effect operates within the common directional processes of movement planning including at least tongue, hand and leg movements, and these processes might contribute sound-to-meaning mappings to the semantic concepts of ‘forward’ and ‘backward’.
