![]() ![]() The results can be used in supporting the learning process of students with difficulties in math. In addition, simultaneous processing of verbal WM predicted problem solving skills in math. Verbal concepts contributed also to the math applying domain. Results from structural equation modelling showed that verbal reasoning and verbal concepts were most consistently associated with math knowing and problem solving domains. The original model of Baddeley & Hitch was composed of three main components the central executive which acts as supervisory system and controls the flow of information from and to its slave systems: the phonological loop and the visuo-spatial sketchpad. Confirmatory factor analyses with binary indicators showed that a four-factor model of math skills (Knowing-Recalling, Knowing-Computing, Applying and Problem Solving) and a nine-factor model of cognitive abilities (Nonverbal and Verbal Reasoning, Verbal Concepts, Planning, Visuo-Spatial Working Memory (WM), two types of Verbal WM, Phonological Awareness and Phonological WM) fit the data well. Participants were 723 third-grade children (mean age = 9.07) from 28 elementary schools. These results confirmed a visual-spatial double dissociation in the visuospatial sketchpad, and subsequently Logie (1995) revised the model of the sketchpad to account for rehearsal by including a mechanism for storing visual information (visual cache) and an active spatially-based mechanism for rehearsal (inner scribe). Here, we investigated such issue through a. However, whether information other than those spatial and visual (i.e., motor information) play also a role in CBT performance is still a matter of debate. Authors: Jean-Michel Passerault Université de Poitiers Jerome Dinet University of. ![]() The focus of this study was to examine associations between a number of cognitive abilities and three domains of math skills (knowing, applying and problem solving) simultaneously in a multivariate framework. The Corsi block-tapping task (CBT) is a widely used experimental tool for assessing visuo-spatial memory in both clinical and research contexts. The Role of Visuo-spatial Sketchpad in the Written Production of Descriptive and Argumentative Texts. Math achievement is not a unidimensional construct but includes different skills that require different cognitive abilities. ![]()
