In an eye-tracking experiment, we showed German native speakers (n=35) two visual scenes depicting an event involving three animate entities, and at the same time they heard a sentence that included a ditransitive verb. The participants’ task was to select the target scene. One half of the 24 ditransitive sentences followed the order indirect object > direct object (IO-DO), the other the order direct object > indirect object (DO-IO). For a fully counterbalanced design, we additionally manipulated the order of masculine and feminine nouns after the verb (Table 1). A previous acceptability judgment task with a separate participant group (n=48) revealed higher ratings for IO-DO than for DO-IO, irrespective of noun order.
Preliminary analyses suggest that it is not just the order of objects, but also the perceptual salience of the case cue that influences the processing of ditransitives: If dative and accusative are marked by der and die respectively, participants prefer the target over the competitor scene prior to the onset of the second object (Figure 1, right), indicating that they are able to predict its thematic role. However, if the difference between dative and accusative corresponds to the difference between dem and den, we observe no stable target preference prior to the second object. Moreover, den corresponds to the condition with the lowest accuracy (73%) and longest response latency.
Our findings extend previous research showing listeners’ predictive use of case marking on sentence-initial arguments to postverbal arguments while controlling for factors such as animacy and perceptual salience.
