Abstract


Traditional definitions of Developmental Dyscalculia state that a child must substantially underachieve on mathematical abilities tests relative to the level expected given age, education and intelligence. However, cognitive developmental neuropsychological studies nowadays suggest that not only core numerical but also cognitive skills of children with developmental dyscalculia present deficits. The main aim of the research protocol was to construct a battery of six tests that can be delivered by computer in order to screen children’s arithmetic and cognitive skills. The hypothesis of the study was that children that are already diagnosed by paper and pencil tests as dyscalculic will present lower scores and larger time latencies not only in arithmetical but also in executive function tasks. A total of 134 right handed children (74 male and 60 female, age range 8 – 12 years) participated in this study. The students with disorders in mathematics (N= 67, 37 male and 30 female age range 8 – 12 years M= 10.15 SD=1.10) had a statement of dyscalculia after assessment at a Centre of Diagnosis, Assessment and Support, as it is required by Greek Law. A comparison group without any learning disabilities was individually matched with the dyscalculic group according to age, sex and grade (N=67, 37 male and 30 female, age range 8 – 12 years old, M=10.24 SD=1.12). Statistical analysis revealed that children with dyscalculia had statistically significant lower mean scores of correct answers and larger time latencies in all tasks compared to their average peers that participated in the comparison group.`
