Children's arithmetic performance is dependent on the arithmetic task format, but little is known about how domain-specific and domain-general abilities contribute to solving diverse arithmetic problems. In this study, 145 Italian typically developing children between the ages of five and six, who have not yet received formal schooling, were…

Several models of working memory (WM) have been proposed in the literature. Most of the research on the architecture of WM is based on adults or older children, but less is known about younger children. In this study, we tested various models of WM on a sample of 739 Italian children, ranging in age from 3 to 8 years, primarily of European…

This study aimed to investigate the relationship between different components of active visuospatial working memory and math ability in young children. In a longitudinal study, we compared the contributions of active visual and spatial working memory (WM) tasks in early math performance at two times: the beginning of the first class of primary…

A novel battery (BAFE; Valeri et al. 2015) was used in order to assess three executive function (EF) abilities (working memory, inhibition and shifting) in a sample of 27 intellectually able preschoolers with autism spectrum disorder (ASD) compared with 27 typically developing children matched on age and nonverbal IQ. Differences in EF skills were…

What supports deaf signers advantage over nonsigners on visuospatial short-term memory (STM) tasks is still a matter of debate. We compared the performance of 18 deaf Italian Sign Language (LIS) users with that of a matched group of Italian hearing nonsigners in three different tasks: two versions of the Corsi Block test, namely span forward and…

The aim of this study was to investigate verbal and nonverbal cognitive deficits in Italian students with developmental dyslexia. The performances of 32 dyslexic students, 64 age-matched typically reading controls, and 64 reading age-matched controls were compared on tests of lexical knowledge, phonological awareness, rapid automatized naming,…

The purpose of the present study was to test the efficacy of a visuospatial working memory (WM) training in terms of its transfer effects and maintenance effects, in the young-old and old-old. Forty young-old and 40 old-old adults took part in the study. Twenty participants in each age group received training with a visuospatial WM task, whereas…

This study examines visual and spatial working memory skills in 35 third to fifth graders with both mathematics learning disabilities (MLD) and poor problem-solving skills and 35 of their peers with typical development (TD) on tasks involving both low and high attentional control. Results revealed that children with MLD, relative to TD children,…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

Four experiments investigated phonemic and visual similarity effects in 5- and 10-year olds. Results suggested that young children rely on modality-dependent codes, which are probably automatically activated, and do not use a speech-based memory code for drawings and words. This pattern of findings appeared to be independent of culture and…
