Dissertation Abstract:
To produce a sentence requires speakers to co-ordinate the production ofwords, so that they are ready for articulation and can be accessed by theproduction mechanism upon demand. Studies in Psycholinguistics havetraditionally found these processes to require about a quarter of a second.Is this true for both children and adults? Or should we expect eitherpopulation to be faster on the task? We here examine possible age-relateddifferences in sentence production across natural images of varyingcomplexity. Speakers described natural scenes depicting both transitive andintransitive verbs, and either a single or two human actors, using or notusing an object. The latency of speech across the three different kinds ofimages suggests that children are faster. Also, the number of fixations,and the number of entries to the different image regions, are more forchildren. However, other eye-tracking measures (e.g. dwell times, dwellpercentages, and average fixation duration times) are more for adults,suggesting a different pattern of attention allocation than that of children.
