  • Early Help Better Future
    Early Help Better Future A Guide to the Early Recognition of Dyslexia by Jean Augur Introduction In the past it was thought that the earliest that a child could be identified as having a dyslexic profile was at about the age of six. This was because, by six, the child was already giving cause for concern particularly as regards reading, writing and spelling, all very important skills in the school curriculum. With experience, however, and from the findings of research studies, it is now evident that there are many signs well before school age which may suggest such a profile and the consequent difficulties ahead. Parents and pre-school carers as well as educators in those early years are amongst those in the best position to recognise these signs, and to provide appropriate activities to help. Training in some of these activities will help to build firm foundations for later, more formal, training. What is Dyslexia? Dyslexia is best described as a specific difficulty in learning, in one or more of reading, spelling and written language which may be accompanied by difficulty in number work, short-term memory, sequencing, auditory and/or visual perception, and motor skills. It is particularly related to mastering and using written language – alphabetic, numeric and musical notation. In addition, oral language is often affected to some degree. Dyslexia occurs despite normal teaching and is independent of socio-economic background or intelligence. It is, however, more easily detected in those with average or above intelligence. 1 Some of the Early Signs which may suggest a Dyslexic Profile General · Family history of similar difficulties; · May have walked early but did not crawl – was a “bottom shuffler” or “tummy wriggler”; · Persistent difficulties in getting dressed efficiently; · Persistent difficulty in putting shoes on the correct feet; Just marking the shoes with “outside” may help to ease the difficulty.

  • Part 7 Developmental Disabilities
    Bringing It All Together You are a group leader on one of the ICF units at SDC, one of the clients in your group is Mickey, a 44-year-old man with Down Syndrome. He is sociable, but mischievous. He can say a few words, such as "toy", "no", and "hurt." He enjoys his vocational activity most of the time but has to be reminded, repeatedly. to get back to work (he has a job shredding paper). His physical treatment profile lists: hypothyroidism, constipation, dermatitis, GERD, and obstructive sleep apnea. When he is angry he vocalizes and pushes people; when he's happy he can be a charmer. 1. As a psychiatric technician you know that Down syndrome is: a. A disorder caused by gestational problems in the neonate b. A genetic abnormality c. Perinatal hypoxia d. Drug exposure during pregnancy Answer: B- Down syndrome, also called Trisomy 21- is a genetic disorder. Perinatal hypoxia has long been suspected of causing cerebral palsy, but there may be other factors involved. Drug exposure during pregnancy is usually worst with resultant F AS. 2. The common characteristics of Down are: a. Short stature, epicanthal fold, smallish head b. Long face, hand flapping c. .:Ylicrocephaly, hirshutism, and severe mental impairment d. Port wine stain Answer: A-Down syndrome. A more complete list would include: Poor muscle tone; Slanting eyes with folds of skin at the inner corners (callcd epicanthal folds); Hyperflexibility (excessive ability to extend the joints); Short, broad hands with a single crease across the palm on one or both hands; Broad feet with short toes; Flat bridge of the nose; Short, low-set ears; Short neck; Small head; Small oral cavity; and/or short, high-pitched cries in infancy.

However, conventional thinking has forced a one – dimensional view on the idea of success. Today, most parents look at aptitude only in terms of grades and certain skill sets. We often opine that only when a child has a certain type of talent, will s/he climb the citadels of success. But look at the history of human accomplishment – some of our greatest men and women have over come challenges to achieve success. Every child has something incredibly special about him or her and as a parent, we have to nurture that talent and always reassure the child about it‟s uniqueness.

  • Comparative Study Between Lisping and Sliping of the Tongue
    Tikrit University Journal for Humanities Vol. ( 14 ) No. ( 3 ) April ( 2007 ) A Comparative Study Between Lisping and Sliping of the Tongue Zaynab Abbudi Ali (M. A) English Department College of Education AL-Qadisaya University 1- Introduction Verbal communication is the only effective means of passing the speech quickly. There are many speech problems that can interfere the speakers's communication and lead to errors in speech production. Lisping and sliping are two speech problems that lead to errors in articulation. This study compares mainly between these two speech problems since many people confuse and can not distinguish between them. However, it also aims at specifying and classifying the difficulties of lispers and slipers in producing the speech sounds. Investigating these issues might serve those researchers who are interested in speech errors. 2-Definition of Lisping and Sliping Lisping, on one hand, refers to a defective production of one or more of the six sibilant consonant sounds [s , z , , , t , d ] ,usually caused by improper tongue placement or by abnormalities of the articulatory mechanism. The [s, z] are the most commonly involved consonant sounds (Nicolosi etal., 1978:124). Likewise, Hudan (2005:1) defines lisping as "a functional speech disorder that involves the inability to pronounce correctly one or more sibilant 15 A Comparative Study Between Lisping and Sliping of the Tongue Zaynab Abbudi Ali (M.A) consonant sounds like [s, z]". It is usually the speaker who slips substitutes the sound [ θ] for the sibilant sounds, for example, the word 'lisp' [l sp] is pronounced as 'lithp' [l θp]. Sometimes, lisping may refer to a disorted or mispronunciation of the speech sounds.

  • Speech-Language Disorders & Therapy Explanation Handouts
    Speech-Language Disorders & Therapy Explanation Handouts for Parents & Teachers By Natalie Snyders, MS, CCC-SLP Making the life of a busy school SLP easier and a bit SPEECH-LANGUAGE PATHOLOGIST more beautiful every day! W W W . S L P N A T A L I E S N Y D E R S . C O M Directions: These handouts are intended to be used by speech-language pathologists to provide information to parents, teachers, and other staff members about the role of speech-language therapy in the school setting, the evaluation & IEP process, what exactly various communication disorders are, and how those communication disorders may impact the academic environment. I highly recommend making multiple copies ahead of time, so you can quickly grab a set when you need them. They are all in black and white, so no need for colored ink! I like to print them on brightly colored paper to help them stand out. I also recommend making stapled packets of relevant pages together (for example, the overview of speech-language therapy, explanation of a phonological disorder, and impact of speech sound disorders pages). These handouts are perfect to hand out during initial or yearly IEP meetings, to teachers at the beginning of the school year to have as a reference and to leave in their substitute binders, and to parents at the start of the school year. Terms of Use: Please note that this download is intended for the use of one SLP/teacher/ Graphics: user only. Please direct others interested to the original product page on TpT; multiple user licenses are available at a 10% discount.

Cleft Palate and Craniofacial Anomalies: The Effects on Speech and Resonance, 3rd edition from Cengage Learning. Non Financial Disclosures • None SOUND JUDGMENT: INTRODUCTION Objectives As a result of this course, participants will be able to: • Use auditory, visual and tactile-kinesthetic cues to enhance the child’s awareness of the misarticulated sound versus the correct sound production. • Apply effective speech therapy techniques for typical speech sound errors. • Use motor learning and motor memory principles to achieve carryover soon after acquisition of the appropriate placement. Course Outline • Anatomical requirements for normal speech • Effects of abnormal structure on speech sound production • Enhancing speech sound awareness • Speech therapy “cookbook” • Achieving carry-over using motor learning principles • Summary ANATOMICAL REQUIREMENTS FOR NORMAL SPEECH SOUND PRODUCTION Normal Speech Production Most speech sounds are produced in the front of the mouth: • Bilabial sounds- p, b, m, w • Labiodental sounds- f, v • Lingual-alveolar sounds- t, d, n, l, s, z • Palatal sounds- ʃ, ʒ, ʧ, ʤ Normal Speech Production • The only speech sounds produced in the back of the mouth are velar sounds (k, g, ŋ) Normal Speech Production • The lips should: • Approximate at rest without effort • Bilabial competence is important for production of bilabial and labiodental sounds Normal Speech Production • The tongue tip should: • Rest under the alveolar ridge • Be able to move up and down, back and forth without interference • Tongue tip movement is important for production of lingual-alveolar and palatal sounds.

    Speech or Language Impairment (SLI) DEVELOPMENT OF SPEECH AND LANGUAGE SKILLS Speech and language skills develop in childhood according to developmental milestones. Sometimes parents and caregivers might become concerned if a child’s language skills seem lagging behind (or different from) the language of their same-age peers. This may motivate concerned These areas are reflected in the Alabama parents to look into the situation and eventually Administrative Code’s definition of speech and have the child evaluated by a professional. language impairment, and is used to authorize There are different kinds of speech and language early intervention services available to children disorders that can affect children, and here are the birth-age 2, and special education available to four major areas in which the impairments occur: school-age (3-21) children with disabilities.
