“…An additional criterion for the group with dyslexia was adequate nonverbal cognitive ability on a shortened version of Raven Progressive Matrices compared to controls. Participants were classified into a group of TD readers (n = 204; M age = 110.51 months; SD age = 7.92) and a dyslexia group (n = 54; M age = 108.37 months; SD age = 8.45) based on their scores on a word-and pseudoword-reading test (Layes et al, 2017(Layes et al, , 2019(Layes et al, , 2020 falling below −1.3 SD of the mean of the total sample. There were no significant differences between the two groups in nonverbal intelligence quotient (IQ) (t = 0.20, p > .05) and age (t = −0.524, p > .05).…”

This study investigated the triple-deficit hypothesis in Arabic, a Semitic transparent orthography, among 258 native Arabic children from Grade 3, divided into a typical readers group (n = 204) and a dyslexia group (n = 54). Children were tested on word- and pseudoword-reading accuracy, word-reading fluency, phonological awareness (PA), naming speed (NS), orthographic processing (OP), and nonverbal reasoning ability. The results indicated that all children with dyslexia had either double or triple deficits, and none of them had a single deficit. Children with triple deficits showed lower performance than children with single and no deficits on all the reading measures. They have also lower performance to children with double deficits on word-reading accuracy but comparable scores in word- and pseudoword-reading fluency. In addition, OP was confirmed as an additional independent predictor of word-level reading skills besides PA and NS, while controlling for age and nonverbal intelligence. The classification findings showed that the presence of a triple deficit maximizes the risk of reading failure. These findings support the additive nature of combined deficits in PA, NS, and OP. Moreover, they establish the benefit of including OP as a third deficit, in addition to PA and NS, underlying dyslexia in Arabic.

Erfassung mentaler Rotationsleistungen im Grundschulalter

Zusammenfassung. Die mentalen Rotationsleistungen als eine Komponente visuell-räumlicher Fähigkeiten stehen in enger Verbindung zur mathematischen Entwicklung sowie zum schulischen und beruflichen Erfolg in den MINT-Fächern. Daneben werden geringe mentale Rotationsleistungen bei Kindern mit einer Lese-Rechtschreibstörung diskutiert. Derzeit ist kein Messinstrument für den Schuleingangsbereich verfügbar, welches sowohl die Lösungsgenauigkeit als auch die Reaktionszeit misst und den allgemeinen Kriterien der Psychometrie (Objektivität, Validität und Reliabilität) entspricht. Anliegen der vorgelegten Untersuchung ist es, diese Lücke zu schließen. In zwei Studien wurde ein computerbasiertes Testverfahren für Schulkinder bis zur dritten Klassenstufe entwickelt, welches die Besonderheiten bei der Erfassung mentaler Rotationsleistungen junger Kinder berücksichtigt. Die vorgenommenen testtheoretischen Betrachtungen an 300 Grundschulkindern waren zufriedenstellend. Die Daten konnten wesentliche Befunde der Literatur bestätigen und wurden kritisch diskutiert. Mit dem cMR liegt nun ein ökonomisches chronometrisches Testverfahren zur Erfassung mentaler Rotationsleistungen vor, welches bereits bei Kindern ab der ersten Klasse einsetzbar ist.
