objective: children with attention deficit hyperactivity disorder (adhd) do not process most information due to inattention and loss of the opportunity to save and retrieve information. therefore, these children experience memory impairment. although visual memory has been previously studied in children with adhd, iconic memory in these children has been less evaluated. we aimed to study the po...

The acquisition of a non-native phonetic distinction by second-language learners relies on basic sensory and perceptual processes. In the present study we examined whether central capacity limitations in attention and immediate memory affected both metalinguistic awareness of phonemic properties of stimuli and the ease with which listeners could perceptually reorganize native phonemic categorie...

Let I be a non empty set, let X be a non-empty many sorted set indexed by I, and let i be an element of I. Note that X(i) is non empty. In the sequel S will be a non void non empty many sorted signature and V will be a non-empty many sorted set indexed by the carrier of S. Let us consider S, V . The functor S -Terms(V ) yielding a non empty subset of FinTrees(the carrier of DTConMSA(V )) is def...

Twenty children with mental retardation (MR), age 7-12, completed a phonological reading skills program over approximately 10 weeks. As a result of the instruction, they were better able to sound out learned and transfer words compared to a control group matched on age, IQ, nonword reading, language comprehension, and phonemic awareness. Final sounding out was predicted by beginning reading ski...

The term nasality refers to the timbre of the nasal phonemes. It is also used to express the quality of sound that characterises some speakers. In this paper, we propose to classify nasality in natural speech into four types: phonemic nasality, nasality in assimilation, incidental nasality in the production of voiced plosives, and nasality associated with speaker individuality. Speech sounds re...

Disproportionately greater deficits in semantic relative to phonemic verbal fluency are seen in Alzheimer's disease (AD) and have been attributed to neurodegenerative changes in the temporal lobe. Amnestic (AMN) mild cognitive impairment (MCI), which often represents incipient AD, is also characterized by early temporal lobe neuropathology, but previous comparisons of verbal fluency between AD ...

In this paper we study properties of symbols such that these belong to class of symbols sitting insideSm ρ,φ that we shall introduce as the following. So for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of M−hypoelliptic pseudodifferential operators for which define base on this class of symbols. Also we consider maxi...

We assessed the Gradient Phonemicity Hypothesis by testing whether a duration-based derived contrast in Scottish English can be seen phonemic just as a contrast based on vowel quality. We examined the electrophysiological correlates of the perception of such contrasts in native Scottish and French speakers. Results revealed differences between the two groups, mostly in the perception of duratio...
