Key Details

Telic verbs have higher peak velocity & shorter duration than atelic verbs

Intensified adjectives have longer duration than non-intensified forms

Motion features mark semantic distinction in verbs, grammatical distinction in adjectives

Individual differences likely indicate personal signing style

Kinematic analysis of endpoint marking in verbs and intensification in adjectives

This paper investigates how signers of Austrian Sign Language use hand motion to convey semantic distinctions in verbs (actions with clear endpoints vs. ongoing actions) and grammatical distinctions in adjectives (intensified vs. non-intensified). Motion capture analysis reveals that telic verbs have higher peak velocity and shorter duration compared to atelic verbs. Intensified adjectives have longer duration compared to non-intensified forms. Individual differences between signers likely reflect personal signing style.
