This paper addresses the techniques of treating patients with functional disorders of pronouncing sibilants in Arabic. The sounds under question are /s/, /z/, /?/. The main disorders that are studied here are: substitution and distortion. A descriptive analytical approach was followed; patients from different ages of functional pronunciation…

Using behavioral, structural, and functional imaging techniques, we demonstrate contrasting effects of vocabulary knowledge on temporal and parietal brain structure in 47 healthy volunteers who ranged in age from 7 to 73 years. In the left posterior supramarginal gyrus, vocabulary knowledge was positively correlated with gray matter density in…

An adult developmental model of self-regulated language processing (SRLP) is introduced, in which the allocation policy with which a reader engages text is driven by declines in processing capacity, growth in knowledge-based processes, and age-related shifts in reading goals. Evidence is presented to show that the individual reader's allocation…

Infants prefer to listen to happy speech. To assess influences of speech affect on early lexical processing, 7.5- and 10.5-month-old infants were familiarized with one word spoken with happy affect and another with neutral affect and then tested on recognition of these words in fluent passages. Infants heard all passages either with happy affect…

While almost all observers agree that young children, older children, and adults differ both in initial rate of acquisition and in the levels of ultimate attainment typically achieved, they continue to disagree over whether the observed patterns are a function of nurture or nature. Is it simply that older starters "do not" do as well because they…

This book examines how the brain enables people to speak creatively and build up an understanding of language. The discussion looks at the linguistic and neuro-anatomical underpinnings of language and considers how language skills can systematically break down in individuals with different types of brain damage. By studying children with language…

This paper concerns the influence of age of acquisition (AoA) in word reading and other tasks, and attempts to develop a number of issues raised by Zevin and Seidenberg (2002). Analyses performed on both rated and objective measures of AoA show that the frequency trajectory of words is a reliable predictor of their order of acquisition, which…
