Study of Numerical Processing Speed, Implicit and Explicit Memory, Active and Passive Memory, Conservation Abilities, and Visual-Spatial Skills of Students with Dyscalculia
Background and Purpose: Learning disorder is one of the common disorders in students, which can lead to the occurrence of educational problems and secondary disorders in them. Based on psychopathological criteria, dyscalculia is one of the subcategories of learning disorder. Children with this disorder have problems in perception of spatial relations and in different cognitive abilities. Theref...
متن کاملبرتری جانبی مغزی پردازش محرک‌های دیداری کلی- جزیی در بیماران مبتلا به اختلال وسواسی- اجباری
Objectives: Clinical and neuropsychological evidence indicate that patients with obsessive-compulsive disorder might have difficulty in early stages of processing visual global-local stimuli. This study was carried out to compare global-local visual processing and its cerebral lateralization among patients with obsessive-compulsive disorder and normal controls. Method: The present study is a ca...
متن کاملAge-related top-down suppression deficit in the early stages of cortical visual memory processing.
In this study, electroencephalography (EEG) was used to examine the relationship between two leading hypotheses of cognitive aging, the inhibitory deficit and the processing speed hypothesis. We show that older adults exhibit a selective deficit in suppressing task-irrelevant information during visual working memory encoding, but only in the early stages of visual processing. Thus, the employme...
متن کاملTime Pressure Modulates Electrophysiological Correlates of Early Visual Processing
BACKGROUND Reactions to sensory events sometimes require quick responses whereas at other times they require a high degree of accuracy-usually resulting in slower responses. It is important to understand whether visual processing under different response speed requirements employs different neural mechanisms. METHODOLOGY/PRINCIPAL FINDINGS We asked participants to classify visual patterns wit...
متن کاملSensitometric characteristics of D-, E- and F-speed dental radiographic films in manual and automatic processing
BACKGROUND: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, E- and F-speed radiographic films (Kodak Eastman, Rochester, USA). All fil...
