Developmental dyslexia may affect as much as 15% of the population, but the aetiology of the disorder is still being debated. The cerebellar theory of dyslexia proposes that cerebellar dysfunction could lead to the myriad of symptoms seen in dyslexic individuals, both in literacy and non-literacy domains. The cerebellum is crucial to the fluent…

This study assesses children's understanding of the Italian modal verbs "dovere" (must) and "potere" (may) in their dual function of qualification of the speaker's beliefs (epistemic modality) and behaviour regulation (deontic modality). 192 children and 60 adults participated in the experiment. Children aged 3;0 to 9;2 were presented with two…

This study used cortical source analysis to locate potential cortical sources of event-related potentials (ERPs) during covert orienting in infants aged 14 and 20 weeks. The infants were tested in a spatial cueing procedure. The reaction time to localize the target showed response facilitation for valid trials relative to invalid or neutral…

While very young children's understanding of objects as symbols for other entities has been the focus of much investigation, very little is known concerning the emergence of comprehension for symbolic relations among actions modeled with toy replicas and their real counterparts. We used videotaped depictions of real actions in a preferential…

This study employed the masked-priming paradigm [Forster and Davis (J Exp Psychol bearn Mem Cogn 10: 680-698, 1984).], along with traditional methods of evaluation of morphological awareness and phonological processing, to obtain a finer-grained picture of the relationship between morphological abilities and reading in adult dyslexic readers.…

Microgenetic methods were used to document young children's (N = 36; M age = 3;5) acquisition of false belief (FB) understanding and investigate developmental mechanisms. A control group received no experience with FB; 2 other groups received microgenetic sessions designed to promote FB understanding. Over consecutive weeks, microgenetic groups…

Children's developing competence with symbolic representations was assessed in 3 studies. Study 1 examined the hypothesis that the production of imaginary symbolic objects in pantomime requires the simultaneous coordination of the dual representations of a dynamic action and a symbolic object. We explored this coordination of symbolic…

To evaluate the claim that correct performance on unexpected transfer false-belief tasks specifically involves mental-state understanding, two experiments were carried out with children with autism, intellectual disabilities, and typical development. In both experiments, children were given a standard unexpected transfer false-belief task and a…

A modified elicited imitation task was used to examine the development of the ability to resist and overcome interference in the 2nd and 3rd years of life. In the modified task, distractor props were included in the test array, so that children could imitate the modeled sequence but could also produce actions with the additional props provided,…

Recent studies have attempted to understand the processes involved in joint attention because of its relevance to both atypical and normal development. Data from a recent study of young children with autism suggests that performance on a delay nonmatch to sample (DNMS) task associated with ventromedial prefrontal functions, but not an…

In this article, the authors describe their experience in extending a manual practice set to accounting software. The "Systems Understanding Aid" by Arens and Ward (2001) has been used for some time in the authors' Accounting Information Systems course. The extension involved requiring students to redo the project using Peachtree Complete…

The Model of Domain Learning (MDL) is an alternative perspective on expertise that arose from studies of student learning in academic domains, such as reading, history, physics, and biology. A comparison of the MDL and traditional models of expertise is made. The key components and stages of the MDL are then overviewed. Discussion concludes with a…

This study examined the concurrent and predictive relations between infant attention skills, joint attention, and emotion regulation. Infants' gaze following skills and duration of orienting were assessed at 6 months of age, and collaborative joint attention and emotion regulation skills were assessed at 24 months of age. The results indicated…

The well-documented evidence that bilinguals demonstrate cognitive advantages over monolinguals is used as a foundation for the hypothesis that bilinguals will be better able to solve certain spatial tasks, and a theoretical framework for this hypothesis is constructed. The paper describes an experiment to explore this hypothesis. A series of…

Deaf and hearing college students' mean reaction times (RTs) were compared on a mental calculation task in which they had to verify the accuracy of solutions to addition and multiplication problems. The deaf students were divided into higher and lower readers. Higher deaf readers and hearing students had similar RTs and accuracy on addition…
