Exploring the temporal boundary conditions of the articulatory in-out preference effect.

Abstract

Earlier research has documented a preference for words with consonantal articulation patterns that move from the front to the back of the mouth (e.g., MENIKA) over words with reversely wandering consonantal articulation spots (e.g., KENIMA). The present experiments explored the temporal dynamics of the reading process in this in-out preference effect. In three experiments (total N = 344), we gradually reduced the presentation durations of inward and outward wandering words from 1000ms down to 25ms to approximate the minimum length of visual stimulus presentation required to trigger the effect. The in-out effect was reliably observed for exposure timings down to 50ms, but vanished for 25ms timings, which is line with previous evidence on phonological encoding. Thus, impressively, 50ms of word presentation is sufficient to evoke the in-out effect. These findings suggest phonological activation to be a prerequisite and thus a driving mechanism of the in-out effect.
