Working Memory is a temporary storage andsimultaneous processing system which, according to Baddeley?s original model has three components: the Central Executive, responsible of the informationprocessing, and the Visuo-Spatial Sketchpad and the Phonological Loop, responsible of information storage during short periods of time. The aim of this article is to test different models on the relationship among thecomponents of Working Memory and the verbalcrystallized system. 180 children of 6-, 8-, and 11-years old participated on the study. The Automated Working Memory Assesment battery, along with Vocabulary of WISC-III were administered. A Path Analysis wasconducted to assess the goodness of fit of the models to the empirical data. Results showed that the Central Executive has a dual effect with the verbal system, both directly and through the Phonological Loop. Thisindicates that retrieval of verbal information doesn?texclusively depends of only one of the Working Memory components.
