Speech and Language Impairment

Speech and Language Impairment — Speech impairment may influence speech in a general way or only certain aspects of it, such as fluency or voice volume. Language impairment may be associated with a more general intellectual impairment.
Language impairment — An impairment in the ability to understand and/or use words in context, both verbally and non-verbally. Some characteristics of language impairment include improper use of words and their meanings, inability to express ideas, inappropriate grammatical patterns, reduced vocabulary and inability to follow directions. One or a combination of these characteristics may occur those who are affected by language learning disabilities or developmental language delay. The person may hear or see a word but not be able to understand its meaning. They may have trouble getting others to understand what they are trying to communicate.
Non-Verbal — Persons who cannot communicate through the use of voice. Persons who are non-verbal must communicate through Augmentative or Alternative Communication Devices.
Speech and Language Impairment (all types)
Speech impairment — The impairment of speech articulation, voice, fluency, or the impairment language comprehension and/oral expression or the impairment of the use of a spoken or other symbol system. Might be characterized by an interruption in the flow or rhythm of speech, such as stuttering, which is called dysfluency. Speech disorders may be problems with the way sounds are formed, called articulation or phonological disorders, or they may be difficulties with the pitch, volume or quality of the voice. There may be a combination of several problems. People with speech disorders have trouble using some speech sounds, which can also be a symptom of a delay. They may say see when they mean ski or they may have trouble using other sounds like l or r. Listeners may have trouble understanding what someone with a speech disorder is trying to say. People with voice disorders may have trouble with the way their voices sound.

Mobility Impairment

Mobility Impairment — Reduced function of legs and feet leads to users depending on a wheelchair or artificial aid to walking. In addition to people who are born with a disability, this group includes a large number of people whose condition is caused by age or accidents.
Cannot walk without aid — It is important that these persons are given proper workstation ergonomics because problems in the legs often cause poor posture which put the person at risk of developing other problems such as back strain.
Mobility Impairments (all types)
Wheelchair user — An employee who uses wheelchairs often requires a modified workstation. The keyboard height, desktop and monitor height need to be adjusted to assure proper ergonomics.

Learning Disability

Learning Disability — A specific learning disability results from problems in one more of the central nervous system processes involved in perceiving, understanding and/or using concepts through verbal (spoken or written) language or nonverbal means. It manifests itself with a deficit in one or more of the following areas: attention, reasoning, processing, memory, communication, reading, writing, spelling, calculation, coordination, social competence and emotional maturity.

It affects:

INPUT

  • How information is taken in.
  • Perception (How it is perceived)
  • Auditorily (How well information is heard)
  • Visually (How well information is seen)
  • Tactually (How well information is input by touch)

INTEGRATION

  • How new information is taken in, understood and linked to old information.
  • Concept formation.
  • How multiple ideas are combined.

OUTPUT

  • How information that has been learned and assimpilated is shown to others.
  • Written expression
  • Organization of thoughts and understanding of Logical Progression.
  • Oral expression (A speech or explanation of what has been learned)
  • Organization of thoughts and understanding of Logical Progression.
  • Demonstration (A project demonstrating what they have learned)
  • Organization of thoughts and understanding of Logical Progression.

Attention Deficit (Difficulty Focusing) — Attention Deficit Disorder is a biologically based condition causing a persistent pattern of difficulties resulting in one or more of the following behaviors:
  • inattention
  • hyperactivity
  • impulsivity
Inattention: difficulty attending or focusing on a specific task. People with Attention Deficit Disorder may become distracted within a matter of minutes. Inattentive behavior may also cause difficulties with staying organized (e.g. losing things), keeping track of time, completing tasks and making careless errors.
Hyperactivity: difficulty inhibiting behavior. These people are in constant motion. They may engage in excessive fiddling, leg swinging and squirming in their chair.
Impulsivity: difficulty controlling impulses. These people do not stop and think before they act. They say and do whatever comes into their mind without thinking about the consequences. They might say something inappropriate and regret it later, blurt out a response to question before a person is done speaking to them or have difficulty waiting for their turn in line.

Dyscalculia — Difficulty performing math calculations. A learning disability which affects math.
Dysgraphia — Difficulty expressing thoughts in writing. It is used to refer to extremely poor handwriting.
Dyslexia — Dyslexia is a learning disability that involves reading. Other similar terms include Dysgraphia (writing disability) and Dyscalculia (math disability). Dyslexia is probably the most common LD term which the general public hears. The word "dyslexia" simply means difficulty understanding written words.
The following are some common signs of Dyslexia:
  • trouble expressing verbal language
  • poor reading comprehension
  • poor spelling
  • difficulty reading — trouble identifying individual words
  • trouble expressing thoughts in written form
  • difficulty listening to or following directions — may hear words incorrectly
  • confusion about directions in space and time, (e.g. left from right, up from down, months of the year)
  • letter reversals (e.g. writing b for d or vice versa), trouble sequencing letters, (e.g. "left" for "felt").
  • may see words as upside down, blurred or distorted
  • difficulty with handwriting
  • difficulty with mathematics — using mathematical symbols,
  • sequencing steps to solve a mathematical problem

Dexterity Impairment Arms Hands Fingers

Dexterity Impairment (Arms/Hands/Fingers) — Reduced function of arms and hands makes activities related to moving, turning or pressing objects difficult or impossible. This does not influence speech communication itself but makes it hard to make a phone call or use a wide range of other equipment.
Cannot use fingers — This can seriously affect a person's ability to use a computer keyboard and mouse.
Cannot use one arm — Causes difficulty in typing. The constant reaching for a mouse and increased demands on the useful arm puts persons in this category at high risk of developing Repetitive Strain Injury in the working arm. A person in this category must be provided with the best possible workstation ergonomics as well as the appropriate assistive device.
Dexterity Impairments (all types)
Hand Tremors — Causes difficulty in writing, keyboarding, mouse use etc.
Reduced co-ordination — Hand/eye coordination is necessary on traditional computers. Cursor movement on the screen responds to minute movements of the mouse by the hand. Typing also requires a certain amount of coordination and dexterity.
Reduced strength — Refers to persons who have disabilities that affect depressing computer keys, mouse clicks, lifting reference material etc. May require adaptations to the workstation that allow for low or no impact computing as well as other workstation modifications.
Reduced Strength—Arm — Persons who have disabilities that affect depressing computer keys, mouse clicks, lifting reference material etc. May require adaptations to the workstation that allow for low or no impact computing as well as other workstation modifications.
Reduced Strength—Hand — Persons who have disabilities, which affect depressing computer keys, mouse clicks, lifting reference material etc. May require adaptations to the workstation that allow for low or no impact computing as well as other workstation modifications.
Repetitive Strain Injury (RSI) — Extremely prevalent in recent years due to the intensive computer use. It is a separate category even though many of the symptoms are covered in other categories. RSI is a result of repetitive procedures that gradually affect the user. It sometimes becomes so severe that the person cannot even pick up a pencil. Risk of RSI can be reduced dramatically through ergonomically designed work stations and prevention training. All computer users should take frequent short breaks and vary physical activities during the day. A saying among health professionals is, It is much harder to get RSI than it is to get rid of it. Prevention is key. Treatment can last up to a year or longer and may include surgery. There are assistive devices designed to aid persons with RSI work in a more natural position and put less strain on the body.

Disability Studies

Disability studies is a relatively new interdisciplinary academic field focusing on the roles of people with disabilities in history, literature, social policy, law, architecture, and other disciplines. Although it has many antecedents, disability studies began to flourish toward the end of the twentieth century. The first PhD program in disability studies in the United States was established in 1998 at the University of Illinois at Chicago.

Definitions

Disability theorists have debated at length how disability should be defined. The theoretical roots for these debates reside in the medical, structural, and minority models. The medical model views disability as equivalent to a functional impairment; the minority model sees a lack of equal rights as a primary impediment to equality between able and disabled populations; and the structural model looks to environmental factors as the cause of disability.

Mission

The field of academic study of disability is growing worldwide; one of its major backers, the transnational Society for Disability Studies, took up the task in the mid-1990s to create an official "definition" for what the field involves. It offers the following working guidelines for any program that describes itself as 'Disability Studies':
  • It should be interdisciplinary/multidisciplinary. Disability sits at the center of many overlapping disciplines in the humanities, sciences, and social sciences. Programs in Disability Studies should encourage a curriculum that allows students, activists, teachers, artists, practitioners, and researchers to engage the subject matter from various disciplinary perspectives.
  • It should challenge the view of disability as an individual deficit or defect that can be remedied solely through medical intervention or rehabilitation by "experts" and other service providers. Rather, a program in disability studies should explore models and theories that examine social, political, cultural, and economic factors that define disability and help determine personal and collective responses to difference. At the same time, Disability Studies should work to de-stigmatize disease, illness, and impairment, including those that cannot be measured or explained by biological science. Finally, while acknowledging that medical research and intervention can be useful, Disability Studies should interrogate the connections between medical practice and stigmatizing disability.
  • It should study national and international perspectives, policies, literature, culture, and history with an aim of placing current ideas of disability within their broadest possible context. Since attitudes toward disability have not been the same across times and places, much can be gained by learning from these other experiences.
  • It should actively encourage participation by disabled students and faculty, and should ensure physical and intellectual access.
  • It should make it a priority to have leadership positions held by disabled people; at the same time it is important to create an environment where contributions from anyone who shares the above goals are welcome.
However, the actual scope of disability studies differs from country to country in spite of its common core. Some, such as the United Kingdom, tend to see the field primarily as primarily belonging only to disabled people and the disability activism they might tend to promote; in the United States, by contrast, a much wider range of professions, such as sociology and social work more generally, which involves both able-bodied and disabled people, may be involved.[citation needed] One of the earliest academic publications in the area was 'Deformity as Device in the Twentieth-Century Australian Novel' (1991), a PhD thesis, at the University of Tasmania, by CA. Cranston.

Criticism

Disability studies is not without its critics. It has been suggested that the dominant social model it uses, which developed in the 1970s and served its purpose well through that era, has now been outgrown, and needs major developments. One major area of contention is the frequent exclusion of the personal experience of impairment, cognitive disability, and illness, which is often left out of most discussion in these circles in the name of "focused" academic discourse. Another concern is the ever-present possibility of a drift towards identity politics in the discipline and also within the disability rights movement as a whole. The social model of disability separates physical impairment from social disability, and in its most rigid form does not accept that impairment can cause disability at all. Scholars are increasingly recognizing that the effects of impairment form a central part of many disabled people's experience, and that these effects must be included for the social model to still be a valid reflection of that experience. Slogan "the personal is political" has been particularly influential in these developments.
Disability studies has also been criticised for its failure to engage with other forms of sociopolitical oppression, such as racism, sexism or homophobia, both as they may apply to disabled people in these oppressed groups, and also in disability studies' ability (or lack thereof) to "unite" with these other movements in common struggle. As a relatively new discipline, critics allege disability studies seems to have made very little progress in this area, in spite of new published writings which deal with these very topics.


















Nonvisible Disabilities

Several chronic disorders, such as diabetes, asthma or epilepsy, would be counted as nonvisible disabilities, as opposed to disabilities which are clearly visible, such as being confined to a wheelchair.

Developmental Disability

Developmental disability is any disability that results in problems with growth and development. Although the term is often used as a synonym or euphemism for intellectual disability, the term also encompasses many congenital medical conditions that have no mental or intellectual components, for example spina bifida.
