The Use of Latent Trait Models in Psycholinguistic Research.
Thompson, Bruce; Barnitz, John
Several applications of latent trait models in reading research are discussed, their nature reviewed, and two experiments presented as heuristic applications of the Rasch Model. Two studies of children's comprehension of selected anaphoric structures in prose were performed using both conventional and Rasch Model analyses. Twenty-six children (grades 2, 4, and 6) in the first study and 91 children (grades 2, 4, and 6) in the second study were asked to read 16 passages containing the pronoun "it." After reading each passage, the subjects responded to a question requiring identification of the pronoun's referent, and the responses were scored right or wrong. Both conventional and Rasch Model scoring procedures revealed that: (1) variances for the three grades were equal in the first study; and (2) no significant sex effect was identified in the second study. Both studies demonstrated that benefits can be derived by utilizing Rasch Model measurement procedures in reading research. Progress in reading research depends upon replication of findings across various studies, and the Rasch Model facilitates this process because item (or person) calibrations are sample (or item) free.
