"Taza" in Spanish refers to cups and mugs in English, whereas glass refers to different glass types in Spanish: "copa" and "vaso." It is still unclear whether such categorical distinctions induce early perceptual differences in speakers of different languages. In this study, for the first time, we report symmetrical…

The "Test of Visual Perceptual Skills -- Fourth Edition" (TVPS-4) is a recently revised assessment of motor-free perceptual abilities, that was standardized in the United States. The TVPS-4 is commonly used by pediatric occupational therapists, health professionals and educators, therefore it is important that its psychometric properties…

In order to address the problem of the underlying mechanism of mathematics learning disability (MLD), in the current research, we investigated the visual and auditory perceptions of elementary school children with visual and auditory MLD from the first to fourth grade. We found that children with visual mathematics learning disability (VMLD) and…

In this study, primary school first grade students' reading skills and visual perception levels were investigated. Sample of the study, which was designed with relational scanning model, consisted of 168 first grade students studying at three public primary schools in Kozlu, Zonguldak, in 2013-2014 education year. Students' reading level, reading…

Although fluency and automaticity of handwriting have been recognized as important research topics for 30 years, empirical data on respective developmental courses among typically developing children as well as clinical samples have remained very limited. To fill this gap, this study investigates the development of handwriting automaticity…

A large part of the empirical research in the field of visual attention has focused on various concrete paradigms. However, as yet, there has been no clear demonstration of whether or not these paradigms are indeed measuring the same underlying construct. We collected a very large data set (nearly 1.3 million trials) to address this question. We…

The development of executive functions in the preschool years is not fully understood. Although there exists a large body of research investigating the maturation of executive functioning in school-aged children, little is known about the emergence of such skills, in particular inhibition, among preschool-aged children. Understanding developmental…

The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The…

In an increasingly aging population, a number of adults are concerned about declines in their cognitive abilities. Online computer-based cognitive training programs have been proposed as an accessible means by which the elderly may improve their cognitive abilities; yet, more research is needed in order to assess the efficacy of these programs. In…

Neurologically normal individuals exhibit strong leftward response biases during free-viewing perceptual judgments of brightness, quantity, and size. When participants view two mirror-reversed objects and they are forced to choose which object appears darker, more numerous, or larger, the stimulus with the relevant feature on the left side is…

Research on the cognitive components of academic achievement subjected White South African schoolchildren to several visual perception tests. Results indicated an association between measures of visual perception and tests of reading and arithmetic performance. Cognitive complexity emerged as an important differentiating feature of perceptual…

Examines perceptions of adults compared with preschool children in assuming object permanence or discontinuity of existence when an object is removed from their immediate perceptual field. Results showed that a belief in the possibility of the discontinuity of material objects is not unique to the minds of preschool children but can also be…

Practice in interpreting the critical features of incomplete line drawings and integrating fragmentary visual information was shown to enhance the visual efficiency of partially sighted children, aged 5 to 8. (BW)
