Learning Disability
Learning disability is a classification that includes several areas of functioning in which a person has difficulty learning in a typical manner, usually caused by an unknown factor or factors. Given the “difficulty learning in a typical manner”, this does not exclude the ability to learn in a different manner. Therefore, some people can be more accurately described as having a “Learning Difference”, thus avoiding any misconception of being disabled with a lack of ability to learn and possible negative stereotyping.
Learning disorders include:
– reading (dyslexia)
– mathematics (dyscalculia)
– writing (dysgraphia)
Individuals with learning disabilities can face unique challenges that are often pervasive throughout the lifespan. Depending on the type and severity of the disability, interventions and current technologies may be used to help the individual learn strategies that will foster future success.

More about Learning Disabilities
While learning disability, learning disorder and learning difficulty are often used interchangeably, they differ in many ways:
– Disorder refers to significant learning problems in an academic area. These problems, however, are not enough to warrant an official diagnosis.
– Learning disability on the other hand, is an official clinical diagnosis, whereby the individual meets certain criteria, as determined by a professional.
The difference is in degree, frequency, and intensity of reported symptoms and problems, and thus the two should not be confused.
– “learning disorder” is used, it describes a group of disorders characterized by inadequate development of specific academic, language, and speech skills.
The disorder that affects the brain’s ability to receive and process information. This disorder can make it problematic for a person to learn as quickly or in the same way as someone who is not affected by a learning disability. People with a learning disability have trouble performing specific types of skills or completing tasks if left to figure things out by themselves or if taught in conventional ways
Individuals with learning disabilities can face unique challenges that are often pervasive throughout the lifespan. Depending on the type and severity of the disability, interventions and current technologies may be used to help the individual learn strategies that will foster future success.
Some interventions can be quite simplistic, while others are intricate and complex.
Current technologies may require student training to be effective classroom supports. Teachers, parents and schools can create plans together that tailor intervention and accommodations to aid the individuals in successfully becoming independent learners. School psychologists and other qualified professionals quite often help design the intervention and coordinate the execution of the intervention with teachers and parents.
Social support may improve the learning for students with learning disabilities.

Definitions
Representatives of organizations committed to the education and welfare of individuals with learning disabilities are known as National Joint Committee on Learning Disabilities (NJCLD.) The NJCLD used the term ‘learning disability’ to indicate a discrepancy between a child’s apparent capacity to learn and his or her level of achievement. Several difficulties existed, however, with the NJCLD standard of defining learning disability.
One such difficulty was its belief of central nervous system dysfunction as a basis of understanding and diagnosing learning disability. This conflicted with the fact that many individuals who experienced central nervous system dysfunction, such as those with cerebral palsy, did not experience disabilities in learning. On the other hand, those individuals who experienced multiple handicapping conditions along with learning disability frequently received inappropriate assessment, planning, and instruction. The NJCLD notes that it is possible for learning disability to occur simultaneously with other handicapping conditions, however, the two should not be directly linked together or confused.
In the 1980s, NJCLD therefore defined the term learning disability as:
The issue of defining learning disabilities has generated significant and ongoing controversy.
The term “learning disability” does not exist in DSM-IV, but it has been added to DSM-5.
The DSM-5 does not limit learning disorders to a particular diagnosis such as reading, mathematics and written expression. Instead, it is a single diagnosis criteria describing drawbacks in general academic skills and includes detailed specifiers for the areas of reading, mathematics, and written expression.
Types of Learning Disabilities
Learning disabilities can be categorized by either the type of information processing affected by the disability or by the specific difficulties caused by a processing deficit.
By stage of information processing
Learning disabilities fall into broad categories based on the four stages of information processing used in learning: input, integration, storage, and output. Many learning disabilities are a compilation of a few types of abnormalities occurring at the same time, as well as with social difficulties and emotional or behavioral disorders
By function impaired
Deficits in any area of information processing can manifest in a variety of specific learning disabilities. It is possible for an individual to have more than one of these difficulties. This is referred to as comorbidity or co-occurrence of learning disabilities.
Response to Intervention (RTI)
Much current research has focused on a treatment-oriented diagnostic process known as response to intervention (RTI). Researcher recommendations for implementing such a model include early screening for all students, placing those students who are having difficulty into research-based early intervention programs, rather than waiting until they meet diagnostic criteria.
Their performance can be closely monitored to determine whether increasingly intense intervention results in adequate progress. Those who respond will not require further intervention. Those who do not respond adequately to regular classroom instruction (often called “Tier 1 instruction”) and a more intensive intervention (often called “Tier 2” intervention) are considered “nonresponders.” These students can then be referred for further assistance through special education, in which case they are often identified with a learning disability. Some models of RTI include a third tier of intervention before a child is identified as having a learning disability.
A primary benefit of such a model is that it would not be necessary to wait for a child to be sufficiently far behind to qualify for assistance. This may enable more children to receive assistance before experiencing significant failure, which may in turn result in fewer children who need intensive and expensive special education services.
The process does not take into account children’s individual neuropsychological factors such as phonological awareness and memory, that can inform design instruction.
By not taking into account specific cognitive processes, RTI fails to inform educators about a students’ relative strengths and weaknesses Second, RTI by design takes considerably longer than established techniques, often many months to find an appropriate tier of intervention. Third, it requires a strong intervention program before students can be identified with a learning disability. Lastly, RTI is considered a regular education initiative and is not driven by psychologists, reading specialists, or special educators.
Assessment of Learning Disabilities
Many normed assessments can be used in evaluating skills in the primary academic domains: reading, including word recognition, fluency, and comprehension; mathematics, including computation and problem solving; and written expression, including handwriting, spelling and composition.
The most commonly used comprehensive achievement tests include the Woodcock-Johnson IV (WJ IV), Wechsler Individual Achievement Test II (WIAT II), the Wide Range Achievement Test III (WRAT III), and the Stanford Achievement Test–10th edition. These tests include measures of many academic domains that are reliable in identifying areas of difficulty.
In the reading domain, there are also specialized tests that can be used to obtain details about specific reading deficits. Assessments that measure multiple domains of reading include Gray’s Diagnostic Reading Tests–2nd edition (GDRT II) and the Stanford Diagnostic Reading Assessment. Assessments that measure reading sub-skills include the Gray Oral Reading Test IV – Fourth Edition (GORT IV), Gray Silent Reading Test, Comprehensive Test of Phonological Processing (CTOPP), Tests of Oral Reading and Comprehension Skills (TORCS), Test of Reading Comprehension 3 (TORC-3), Test of Word Reading Efficiency (TOWRE), and the Test of Reading Fluency. A more comprehensive list of reading assessments may be obtained from the Southwest Educational Development Laboratory.
The purpose of assessment is to determine what is needed for intervention, which also requires consideration of contextual variables and whether there are comorbid disorders that must also be identified and treated, such as behavioural issues or language delays. These contextual variables are often assessed using parent and teacher questionnaire forms that rate the students behaviours and compares them to standardized norms.
However, caution should be made when suspecting the person with a learning disability may also have dementia, especially as people with Down’s syndrome may have the neuroanatomical profile but not the associated clinical signs and symptoms. Examination can be carried out of executive functioning as well as social and cognitive abilities but may need adaptation of standardised tests to take account of special needs.
Management of Learning Disabilities

Sternberg has argued that early remediation can greatly reduce the number of children meeting diagnostic criteria for learning disabilities.
He has also suggested that the focus on learning disabilities and the provision of accommodations in school fails to acknowledge that people have a range of strengths and weaknesses, and places undue emphasis on academic success by insisting that people should receive additional support in this arena but not in music or sports.
Other research has pinpointed the use of resource rooms as an important—yet often politicized component of educating students with learning disabilities.
These are the recommended practical interventions to ensure a beneficial learning environment:
Causes of Learning Disabilities
The causes for learning disabilities are not well understood, and sometimes there is no apparent cause for a learning disability. However, some causes of neurological impairments include:
– Heredity – Learning disabilities often run in the family. Children with learning disabilities are likely to have parents or other relatives with similar difficulties.
– Problems during pregnancy and birth – Learning disabilities can result from anomalies in the developing brain, illness or injury,
Fetal exposure to alcohol or drugs, low birth weight, oxygen deprivation, or by premature or prolonged labor.
– Accidents after birth – Learning disabilities can also be caused by head injuries, malnutrition, or by toxic exposure (such as heavy metals or pesticides).
Impact on affected individuals
The effects of having a learning disability or learning difference are not limited to educational outcomes: individuals with learning disabilities may experience social problems as well. Neuropsychological differences can impact the accurate perception of social cues with peers.
Researchers argue persons with learning disabilities not only experience negative effects as a result of their learning distinctions, but also as a result of carrying a stigmatizing label.
It has generally been difficult to determine the efficacy of special education services because of data and methodological limitations.
Emerging research suggests adolescents with learning disabilities experience poorer academic outcomes even compared to peers who began high school with similar levels of achievement and comparable behaviours.
It seems their poorer outcomes may be at least partially due to the lower expectations of their teachers; national data show teachers hold expectations for students labeled with learning disabilities that are inconsistent with their academic potential (as evidenced by test scores and learning behaviours).

Social correlates
Critique of the medical model
Learning disability theory is founded in the medical model of disability, in that disability is perceived as an individual deficit that is biological in origin.
Researchers working within a social model of disability assert that there are social or structural causes of disability or the assignation of the label of disability, and even that disability is entirely socially constructed.
The diagnosis of learning disabilities is prevalent in Western capitalistic societies because of the high value placed on speed, literacy, and numeracy in both the labor force and school system.
