PSYCHOMETRIC LATENT RESPONSE MODELS

In this paper, some psychometric models will be presented that belong to the larger class of Intent response models (LRMs). First, LRMs are introduced by means of an application in the field of componential ite m response theory (Embretson, 1980, 1984). Second, a general definitio n of LRMs (not specific for the psychometric subclass) is given. Third , some more psychometric LRMs, and examples of how they can be applied , are presented. Fourth, a method for obtaining maximum likelihood (ML ) and some maximum a posteriori (MAP) estimates of the parameters of L RMs is presented. This method is then applied to the conjunctive Rasch model. Fifth and last, an application of the conjunctive Rasch model is presented. This model was applied to responses to typical verbal ab ility items (open synonym items).
