AbstractThe study explores the role of stress and vowel harmony as cues for speech segmentation. Both in French and in Turkish stress is demarcative, typically falling on word-final syllables. Additionally, Turkish (but not French) has a regular front-back vowel harmony which dictates that all vowels within a word must be either front or back. French and Turkish participants performed a target detection task in which they had to spot nonsense words embedded in a longer auditory string. The results show that word-final stress can successfully signal an upcoming word boundary and is used for speech segmentation by speakers of both languages. In the Turkish group but not in the French group we also found a facilitatory effect of vowel disharmony. We conclude that both vowel harmony and stress can independently signal word boundaries and suggest that listeners can exploit these phonological regularities during speech segmentation.

Perceptual Phenomenon

Apparent motion is a robust perceptual phenomenon in which observers perceive a stimulus traversing the vacant visual space between two flashed stimuli. Although it is known that the “filling-in” of apparent motion favors the simplest and most economical path, the interpolative computations remain poorly understood. Here, we tested whether the perception of apparent motion is best characterized by Newtonian physics or kinematic geometry. Participants completed a target detection task while Pacmen- shaped objects were presented in succession to create the perception of apparent motion. We found that target detection was impaired when apparent motion, as predicted by kinematic geometry, not Newtonian physics, obstructed the target’s location. Our findings shed light on the computations employed by the visual system, suggesting specifically that the “filling-in” perception of apparent motion may be dominated by kinematic geometry, not Newtonian physics.
