title: Sensitivity to Morphosyntactic Information in 3-Year-Old Children With Typical Language Development: A Feasibility Study.
abstract: This study tested the feasibility of a method designed to assess children's sensitivity to tense/agreement information in fronted auxiliaries during online comprehension of questions (e.g., Are the nice little dogs running?). We expected that a group of children who were proficient in auxiliary use would show this sensitivity, indicating an awareness of the relation between the subject-verb sequence (e.g., dogs running) and preceding information (e.g., are). Failure to grasp this relation is proposed to play a role in the protracted inconsistency in auxiliary use in children with specific language impairment (SLI).
  
  
  
  Fifteen 3-year-old typically developing children who demonstrated proficiency in auxiliary use viewed pairs of pictures showing a single agent and multiple agents while hearing questions with or without an agreeing fronted auxiliary. Proportion looking to the target was measured.
  
  
  
  Children showed anticipatory looking on the basis of the number information contained in the auxiliary (is or are).
  
  
  
  The children tested in this study represent a group that frequently serves as a comparison for older children with SLI. Because the method successfully demonstrated their sensitivity to tense/agreement information in questions, future research that involves direct comparisons of these 2 groups is warranted.
