Traditionally, the information in speech signals is represented in terms of features derived from short-time Fourier analysis. In this analysis the features extracted from the magnitude of the Fourier transform (FT) are considered, ignoring the phase component. Although the significance of the FT phase was highlighted in several studies over the recent three decades, the features of the FT phas...

The present study investigated the use of L2 private speech by English foreign language (EFL) learners in regulating their mental activities. Thirty intermediate adult EFL learners took a test of solving challenging English riddles while their voices were being recorded. Following, instances of the produced private speech were analyzed in terms of form, content, and function. Numerous instances...

after finishing the collection of language elements which they wanted to restrict to the arabian peninsula, after organizing and categorizing them under deliberate subjects which include all the language aspects and finally after fulfilling all those scholastic stages, the syntax scholars found another scholastic stage which they felt obliged to deal with and this stage is ‘cause finding’. they...

One of the core defining components of autism is impairment in communication, typically manifested as a delay in speech development. To date, neuroimaging studies have shed limited light on the mechanisms behind delay in speech development in autism. We performed magnetoencephalographic-based auditory language mapping in 2 cases of high-functioning autism. Overall, 2 distinct characteristics we...

BACKGROUND AND PURPOSE Pure speech delay is a common developmental disorder which, according to some estimates, affects 5%-8% of the population. Speech delay may not only be an isolated condition but also can be part of a broader condition such as global developmental delay. The present study investigated whether diffusion tensor imaging tractography-based connectome can differentiate global de...

Communicative language use largely entails regular patterns consisting of pre-constructed phrases or sequences. These sequences have been examined by many researchers to find the situation-based formulas which may help L2 learners follow a possibly more target-like speaking system. This study, therefore, explored two categories of formulaic expressions including speech formulas and situation-bo...

Speech and language delay affects 5% to 8% of preschool children, often persists into the school years, and may be associated with lowered school performance and psychosocial problems. The USPSTF found insufficient evidence that brief, formal screening instruments that are suitable for use in primary care for assessing speech and language development can accurately identify children who would b...

Background: Agenesis of Corpus Callosum (ACC) is a type of brain dysgenesis with various clinical manifestations. Objectives: This study aimed to investigate the clinical and neurodevelopmental outcomes of patients with ACC. Materials & Methods: In this cross-sectional study, the clinical and neurodevelopmental conditions of 62 patients with complete ACC referred to subspecialty clinics of pe...
