The size congruity effect (SiCE) shows that number and physical size interact as magnitudes. That is, response times are faster when number and size are congruent (e.g., 2 4) than when they are incongruent (e.g., 2 4). A shared representational system has been the most influential account for the SiCE. Recently, this account has been challenged by…

Long-term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid-level deficits such as contour integration and motion coherence, to high-level face and object agnosia. Yet it is unclear whether training during adulthood, at a post-developmental…

Fragile X syndrome (FXS) is associated with significant language and communication delays, as well as problems with attention. This study investigated early language abilities in infants and toddlers with FXS (n = 13) and considered visual attention as a predictor of those skills. We found that language abilities increased over the study period of…

Computer simulations are often considered effective educational tools, since their visual and communicative power enable students to better understand physical systems and phenomena. However, previous studies have found that when students read visual representations some reading difficulties can arise, especially when these are complex or dynamic…

Literature suggests that drawing has an important role in the development of learning and thinking skills and the communication of ideas. However, the role and use of drawing by young learners within the process of designing is poorly understood. Working with 22 Grade 3 learners from a well-resourced school in KwaZulu-Natal, this study sought to…

Background: The most common problems in individuals with autistic spectrum disorders are eye contact, being able to follow objects for a long time and lack of attention. Sports activities are known to prevent the negative symptoms of Autistic Spectrum Disorder. The Badminton sports branch has a positive effect on the individual's object control,…

Recent evidence suggests that 3-year-olds can take other people's visual perspectives not only when they perceive different things (Level 1) but even when they see the same thing differently (Level 2). One hypothesis is that 3-year-olds are good perspective takers but cannot confront different perspectives on the same object (Perner, Stummer,…

Many species, including humans, display group behavior. Thus, perceiving crowds may be important for social interaction and survival. Here, we provide the first evidence that humans use ensemble-coding mechanisms to perceive the behavior of a crowd of people with surprisingly high sensitivity. Observers estimated the headings of briefly presented…

Distractor dilution, which reflects little distractor interference in a context of high display load but easy target processing, has sparked debate between theoretical viewpoints. These two viewpoints can be integrated into a model in which grouping and the efficacy of attention control influence the relative activation strength between the…

Research has illuminated contributions--usually modeled separately--of both executive functioning (EF) and visuomotor integration (VMI) to mathematical development in early elementary school. This study examined simultaneous associations of EF and VMI, measured at the beginning of the school year, with concurrent and later mathematics performance…

From early in development, segmenting events unfolding in the world in meaningful ways renders input more manageable and facilitates interpretation and prediction. Yet, little is known about how children process action structure in events composed of multiple coarse-grained actions. More importantly, little is known about the time course of action…

With eye-tracking technology the eye is thought to give researchers a window into the mind. Importantly, eye-tracking has significant advantages over traditional online processing measures: chiefly that it allows for more "natural" processing as it does not require a secondary task, and that it provides a very rich moment-to-moment data…

Theoretical perspectives of cognitive development have maintained that functional integration of the prefrontal cortex across infancy underlies the emergence of attentional control and higher cognitive abilities in early childhood. To investigate these proposed relations, we tested whether functional integration of prefrontal regions across the…

The aim of this study was to examine in visual and auditory reaction time of adolescents with respect to their academic achievement level. Five hundred adolescent children from the Turkey, (age=15.24±0.78 years; height=168.80±4.89 cm; weight=65.24±4.30 kg) for two hundred fifty male and (age=15.28±0.74; height=160.40±5.77 cm; weight=55.32±4.13 kg)…

The purpose of this article is to review the literature and apply a developmental neuroscience perspective in investigating the role of two interrelated cognitive processes--executive functions (EFs) and visuospatial (VS) skills--which have been empirically and theoretically linked to children's mathematics achievement. To illustrate, we provide…
