How children and adults encode causative events cross-linguistically: implications for language production and attention

This study investigates the implications of language-specific constraints on linguistic event encoding for the description and on-line inspection of causative events. English-speaking and Greek-speaking adults, 3-year-olds, and 4-year-olds viewed and described causative events, which are composed of Means and Result subevents, in an eyetracking study. The results demonstrate cross-linguistic differences in the informational content of causative event descriptions: Greek speakers across age groups were more likely than English speakers to mention only one causative subevent. Developmental changes in the tendency to encode information about causative events in language were also evident: in both language groups, adults were more likely than children to mention both Means and Result subevents. Finally, for both adult and child speakers of both languages, preparing different types of event descriptions changed the way that events were visually inspected, shifting attention toward to-be-encoded subevents. These findings offer some of the first evidence about the development of the language production system, the attentional mechanisms that it employs, and its workings in speakers of different languages.
