Learning disabilities
Learning
disability encompasses a wide range of learning and/or social difficulties.
People
with learning disabilities are usually of average to above average intelligence.
The effects of a learning disability
may be mild, moderate or severe.
There are different types of learning
disabilities, including auditory or visual perceptual difficulties, motor
difficulties, poor memory, inattention and concentration difficulties,
difficulty with mathematical reasoning or with reading and writing, etc.
Some
people present with only one particular difficulty while others present with a
combination of difficulties.
It
is important to distinguish learning disabilities from academic difficulties due
to lack of opportunity, poor teaching, cultural factors, inadequate curriculum
or family problems.
Psychologists, remedial teachers, occupational therapists, speech and language
therapists, physiotherapists and neuro-developmental paediatricians are the
professionals who are mostly involved in the assessment and treatment of
learning disabilities
Description
Children, adolescents and adults who experience learning disabilities
usually function on an average to above average intellectual level, with large
discrepancies between their general abilities and specific areas of difficulty.
Intelligence can be defined in many ways. Some people have particular strengths,
such as using their hands for detailed work, understanding emotions or
demonstrating a specific talent in art or music. Some people have specific
deficits or weaknesses in a particular area of cognitive functioning that
affects learning and in turn reading, writing or mathematical ability. The
effects of learning disabilities may be mild, moderate or severe. Learning
disability encompasses a wide range of learning and/or social difficulties. Such
difficulties may include one or more of the following areas:
Understanding,
remembering or producing language, i.e. difficulty with listening, speaking,
reading, writing and spelling
Reasoning,
both verbally and non-verbally
Mathematics, which includes arithmetic
and mathematical reasoning
Motor
co-ordination, both gross and fine
Noticing and remembering social
information
Processing
information, which includes reading and writing speed
Organising
time and/or space
Learning
disabilities are not primarily due to physical disability, such as impairment of
hearing, motor abilities or sight, mental disability or retardation, emotional
issues or mental illness, or environmental disadvantages such as poverty.
Many
children with learning disabilities may function within the average or even
above average range in their grade at school. The learning disorder may not be
fully apparent until grade four or later. The manifestations of learning
disabilities change with the demands at school, as the need for more independent
work increases. As these demands change, the severity of the problem also
changes. Without help, nearly 40 percent of children and adolescents with
learning problems drop out of school. Learning difficulties can be detrimental
to a person’s self-esteem.
Types of
learning disabilities
Dyslexia is difficulty in using and
understanding language. Problems may occur in the areas of listening, speaking,
reading, spelling and/or writing. Despite these difficulties, people with
dyslexia can be extremely creative and talented. They often excel in the visual
arts, drama, sport, mechanics and many other areas that require visual-spatial
integration.
The following are some common signs of dyslexia:
Difficulty
with verbal expression
Poor
reading comprehension
Poor
spelling
Difficulty
identifying individual words when reading
Difficulty
expressing thoughts in written form
Difficulty in following instructions –
may hear words incorrectly
Confusion
about directions in space and time, such as distinguishing left from right, up
from down, months of the year, etc.
Letter reversals and may see words as
upside down, blurred or distorted
Difficulty with handwriting
Difficulty with mathematics, for
example using mathematical symbols or sequencing steps to solve a mathematical
problem
Dysgraphia is being unable to produce
legible handwriting in an appropriate length of time.
Dyscalculia is being unable to
understand or use mathematical concepts and symbols. People with dyscalculia may
have difficulty performing even the simplest mathematical calculations.
Non-verbal
learning disorder (NLD) is a neurological syndrome affecting the right
hemisphere of the brain. People with NLD usually have outstanding verbal
abilities and do well in subjects requiring reading, writing and speaking. They
learn primarily through verbal skills such as listening and speaking.
The three major non-verbal areas affected include:
Gross
and fine motor co-ordination – severe balance problems and difficulty with
handwriting
Visual-spatial organisation
Social skills – inability to use and
understand non-verbal communication such as eye contact and body language
Memory disabilities can be
divided into four categories:
Short-term
auditory memory – difficulty in remembering orally given (spoken) information in
the short term
Long-term
auditory memory – difficulty in remembering orally given information in the long
term
Short-term
visual memory – difficulty in remembering visual information in the short term
Long-term visual memory – difficulty
in committing visual information to long-term memory
These memory difficulties present
significant problems in academic study. You might listen attentively during a
class or lecture, or study hard for a test, but soon realise that you can't
remember the information. Sometimes people have an intact long-term memory, but
a poor short-term memory; in other words, once the information has been
‘over-learnt’ (learnt and revised a number of times) it can be remembered in the
long term.
Auditory
processing disability is difficulty in processing and/or understanding
information that is orally given and perceived aurally (heard). The deficit does
not involve physical hearing problems such as deafness, but does affect how the
brain interprets and/or processes auditory information. This disability can
affect all areas of language development including reading, spelling, speech and
the ability to understand verbal instructions.
Types of auditory processing deficits:
Auditory discrimination difficulty:
difficulty in discriminating between similar sounds such as ‘th’ and ‘f’ or ‘th’
and ‘v’. People with an auditory discrimination problem may have trouble
distinguishing between tones of voice such as those used when a speaker is
making a joke or is being serious.
Auditory
figure-ground difficulty: difficulty in hearing sound over background noise; for
instance, having trouble hearing what someone is saying to you when the
television is on in the background.
Auditory
sequencing difficulty: difficulty in hearing sounds in the correct order. For
example, people with auditory sequencing problems may hear "two – one" instead
of "one – two".
Visual perceptual disability involves
having difficulty in processing and/or interpreting visually perceived
information. This does not mean that you have visual acuity difficulty or visual
impairment; it has to with how the brain interprets and makes sense of visual
information.
Types of visual perception difficulties:
Visual
figure-ground problem: difficulty in distinguishing between a specific image and
a competing background, locating somebody in a crowd, finding an object on a
crowded desk, or picking out one line of print from a page of written
information. People with this disability struggle to visually pay attention to
visual detail and are unable to spot things the way others can.
Visual sequencing problem: difficulty
in seeing things in the correct order. People with this disability see words,
letters and numbers in reverse or in a different order. This causes significant
difficulties with reading and writing.
Visual
discrimination problem: difficulty in seeing differences between two similar
objects. People with this problem may see two similar letters as alike, such as
‘u’ and ‘v’. They may also have trouble telling the difference between two
shades of one colour.
Depth perception problem: difficulty
in perceiving distance. People with this disability have trouble telling how far
away or how near an object is – they may misjudge the corner of a chair, for
example, and walk into it.
Speech
and language disability involves difficulty in expressing verbal language. It is
also known as dysnomia. People with this disability may have trouble remembering
names or recalling appropriate words in a discussion. This problem may be
particularly prominent if the person is asked a question to which he/she must
supply an immediate answer. The person struggles to find the appropriate word(s)
to adequately express what he or she wants to say. However, when the person
speaks spontaneously, without prompting, his or her speech appears perfectly
normal.
Organisational
disability: difficulty in organising time, tasks or space.
People who have difficulty in
organising time have trouble understanding and estimating time. They are
frequently late for appointments.
People
who have difficulty in organising tasks struggle to organise their thoughts to
complete a given task. They process each piece of information separately but
have difficulty merging the pieces into a whole. They usually struggle with
essay writing, particularly under exam conditions. Some people who struggle to
organise tasks have difficulty thinking in an orderly, logical manner. They may
jump to conclusions and have difficulty planning tasks. They also have
difficulty in organising the tasks of daily living. Their bedroom or house is
often in a mess and they often can’t find things. They frequently forget things
or lose their belongings.
People who have difficulty in
organising space have trouble finding their way to different locations. They may
frequently get lost and need directions. Once given directions, they may have
trouble following them, confusing left and right. They may also have difficulty
with learning the layout of large buildings.
Motor disability involves having
difficulty in using your body to perform a physical task. Motor disabilities
generally fit into two categories:
Gross-motor disability: difficulty co-ordinating
large muscles to perform an activity. People with gross-motor difficulties may
stumble when walking, have difficulty running, riding a bicycle or participating
in sports activities, and are generally considered to be clumsy.
Fine-motor disability: difficulty co-ordinating
the small muscles needed for writing or drawing. Handwriting may be a slow,
messy and tedious process. People with this difficulty may have trouble
performing other fine-motor tasks such as typing, tying their shoelaces or
buttoning a shirt. This disability is also known as dyspraxia.
Social skills deficit involves having
difficulty using and understanding social information and conversations. People
with this disability may experience difficulty in the following areas:
Understanding social conventions. Some
people with learning disabilities have trouble understanding the established
social conventions used in daily living. They may have trouble monitoring their
own behaviour and act or speak without forethought. They may laugh
inappropriately and interrupt conversations. A common problem for people with
learning disabilities is difficulty in recognising language conventions. They
may not understand the expected reply to many common phrases. They may take
things literally.
Visual
perception of facial expression and body language. Some people with learning
difficulties misinterpret messages people give and receive through body language
and facial expression.
Auditory
perception of vocal cues. Difficulties with auditory perception affect a
person’s ability to interpret vocal tone. They may have trouble deciding whether
somebody is using an angry voice or expressing feelings of boredom or
impatience. This difficulty can lead to misunderstandings and is likely to be
very frustrating for all involved.
Body
awareness. Some people with learning disabilities have trouble situating their
bodies at a comfortable distance away from others. They do not understand how
close they are to someone with whom they are interacting and how uncomfortable
this may be for that person.
Inattention and concentration
difficulties usually involve distractibility and/or hyperactivity/impulsivity.
This is the inability to focus and sustain attention and concentration. You are
easily distracted by extraneous stimuli, are overactive or lose focus and
daydream. Some people concentrate better with auditory information and others
with visual information. Concentration and inattention difficulties usually
accompany learning disabilities and this does not necessarily mean that you have
an attention deficit/hyperactivity disorder (ADHD).
Associated problems
Ten to
25 percent of individuals with learning disabilities have associated problems
such as conduct disorder, oppositional defiant disorder, major depressive
disorder, or attention deficit/hyperactivity disorder.
Cause
There is strong evidence that learning disabilities are hereditary
(run in families). Injury to the brain through accidents and illness also
contributes to learning difficulties.
Although
learning disabilities are assumed to be the result of variations in brain
structure and function, at present these variations are not well understood.
Research on the brains of brain-injured children and adults is beginning to
provide some valuable information.
Children
with learning disabilities process information differently. Learning
disabilities are caused by a faulty brain system, either in the structure of the
brain or the functioning of different chemicals. Underlying abnormalities in
cognitive processing such as visual perception, linguistic processes, attention
and memory often precede or are associated with learning disabilities. Genetic
predisposition, perinatal injury and various neurological and other general
medical conditions may be associated with learning disabilities, but the
presence of such conditions does not necessarily presuppose a learning disorder.
Learning disabilities are, however, frequently found in association with a
variety of general medical conditions such as lead poisoning, foetal alcohol
syndrome and fragile X syndrome (an inherited genetic condition associated with
mental retardation).
Prevalence
Approximately 10 – 30 percent of children have learning difficulties.
Boys are diagnosed more often with reading, language and concentration
difficulties than girls are.
Diagnosis
When a child’s achievement in reading, mathematics or written
expression is substantially below what is expected in relation to his or her
age, schooling and level of intelligence, a learning disorder may be diagnosed.
Co-operation among the family, the school (if the person is still at school) and
the professionals involved is crucial. A complete diagnostic evaluation of
skills can provide the basis for individualised treatment strategies for schools
and families. A psychologist who has specialised in the field of learning
disabilities usually conducts such an evaluation, also called a
psycho-educational assessment. There is often a team of professionals involved
in the assessment and identification of learning difficulties. These include the
following:
Occupational therapists
Physiotherapists
Speech and language therapists
Remedial
teachers
Neuro-developmental paediatricians
Psychologists
Learning
difficulties can sometimes be identified as early as three years of age.
The list
below contains elements that should be prevalent in order to identify certain
specific learning disabilities. (This does not, however, replace the qualified
professional in diagnosing learning disabilities. It merely provides a guideline
for teachers and parents of children who may present with learning disabilities,
and gives guidance on whether professional diagnosis should be considered.)

Intervention
With early identification and intervention, the prognosis is good in
a significant percentage of cases. Early identification (pre-puberty) can
prevent or limit frustration and failure in school, as well as associated
emotional, social or family problems. It is becoming more accepted that
adolescents and adults who present with specific learning difficulties can be
assisted, even if only to be taught how to compensate for their weaknesses in
cognitive functioning and hence learning. Intervention usually includes one or
more of the following:
Individual
or group remedial lessons by a trained remedial teacher
Occupational therapy for children with
NLD, motor disabilities and visual perception disabilities
Physiotherapy
for NLD and motor disabilities
Speech and language therapy for
children with specific language difficulties and auditory perception
disabilities
Social
skills groups and behavioural management for children to help them to be more
aware of appropriate behaviour and social expectations.
Education
for family members on the ramifications of learning disabilities and the effect
on family functioning
In
South Africa, the Department of Education offers special dispensations for
Learners with Special Educational Needs. These must be applied for by the school
and include:
Extra
time for exams
Spelling concession
Handwriting
dispensation
Oral
exams
A
planning aid for exam writing
Questions on tape

Before
making use of any of the above-mentioned interventions, consult with one or more
of the professionals who work with learners who have special educational needs
and together decide on an intervention plan. Employing some of the above
suggestions in the classroom context would benefit all learners, not only those
with special educational needs.
