This document discusses language and literacy disorders. It begins by outlining normal language development milestones in infants and children. It then describes various types of communication disorders including hearing impairment, learning disabilities, autism, and neurological disorders. Specific language disorders are defined, such as dyslexia, dysgraphia, and dyscalculia. Symptoms of each learning disability are provided for young children, school-aged children, and teenagers/adults. The document explains how communication disorders can affect learning and literacy development.
2. OVERVIEW OF THE NORMAL
DEVELOPMENT OF LANGUAGE
• As the speech mechanism (jaw, lips and tongue) and voice
mature, an infant is able to make controlled sounds.
• By 6 months, an infant usually babbles or produces repetitive
syllables such as "ba, ba, ba" or "da, da, da."
• By the end of their first year, most children have mastered the
ability to say a few simple words.
• By 18 months of age, most children can say eight to ten
words.
• By age 2, most are putting words together in crude sentences
such as "more milk."
• At ages 3, 4, and 5, a child's vocabulary rapidly increases, and
she or he begins to master the rules of language.
3. COMMUNICATION DISORDER
Communication disorders
may range from simple
sound repetitions such as
stuttering to occasional
misarticulation of words to
complete inability to use
speech and language for
communications (aphasia).
4. CAUSES
• Hearing impairment
• Learning disabilities
• Autism
• Schizophrenia
• Cerebral palsy
• Physical disability: cleft lip and palate, or malformations of the mouth
or nose
• Significant behavior or emotional problems, including deficits in
social skills
• Vocal cord injury
• Neurological disorders and diseases
• Head trauma
• Stroke
5. How do speech, language,
and hearing disorders
affect learning?
Why are speech and
language skills so critical
for literacy?
What are signs that a
communication disorder is
affecting school performance?
6. A communications disorder can affect
the way a child talks, hears, processes,
and understands information and can even
influence behavior and emotional
problems. Gone unchecked, a
communications disorder can hinder a child
on the playground, the classroom, and
eventually, in the workplace
7. Communication disorders can be
in the form of:
1.) Hearing disorders
a.) Deafness
b.) Hearing loss of various degrees and origins
c.) Auditory processing problems
-Sometimes it is referred to as central auditory
processing disorder (CAPD), auditory perception problem, auditory
comprehension deficit, central auditory dysfunction, central deafness
and so-called "word deafness."
Cannot process the information although it is loud and clear which
leads to difficulties in recognizing and interpreting sounds
8. Communication disorders can be
in the form of:
2.) Speech and language disorders
a.) Articulation problems
difficulty learning to physically produce the intended phonemes.
b.) Voice disorders
difficulties with the quality, pitch and loudness of the voice (prosody)
Pitch deviations
Deviations in loudness of the voice
Quality deviations
9. Communication disorders can be
in the form of:
3.) Fluency Problems
Stuttering
- a disruption in the flow of speech. It includes repetitions
of speech sounds, hesitations before and during speaking and, or,
prolongations of speech sounds.
10. Communication disorders can
be in the form of:
4.) Aphasia
-the loss of previously learned communication skills that results from
damage to portions of the brain responsible for language
A)EXPRESSIVE APHASIA: you know what you want to say, but you
have trouble saying or writing what you mean. Understands another person's
speech but has trouble responding quickly.
B) RECEPTIVE APHASIA: you hear the voice or see the print, but you
can't make sense of the words. Usually speaks in long sentences that have
no meaning or content. People with this type of aphasia often have trouble
understanding other's speech and generally do not realize that they are not
making any sense.
11. Communication disorders can be
in the form of:
C.) ANOMIC APHASIA: you have trouble using the correct
words for objects, places or event.
-also known as nominal aphasia.
- has difficulty remembering or recognizing names which the subject
should know well. The subject speaks fluently, grammatically, has
normal comprehension, and the only deficit is trouble with "word
finding," that is, finding appropriate words for what they mean to say.
a.) Averbia- specific type of anomia in which the subject has trouble
remembering verbs.
b.) Color anomia- Specific type of anomic where the patient can
distinguish between colors but cannot identify them by name
D.) GLOBAL APHASIA: you can't speak, understand speech,
read or write.
12. Communication disorders can be
in the form of:
5.) DELAYED LANGUAGE:
-characterized by a marked slowness in the
development of language skills necessary for
expressing and understanding thoughts and ideas.
14. LEARNING DISABILITIES
1.) Dyslexia
-A learning disability that can hinder a person's ability to
read, write, spell, and sometimes speak
- Children with dyslexia have difficulty in learning to read
despite traditional instruction, average intelligence, and an
adequate opportunity to learn. It is caused by an impairment in the
brain's ability to translate images received from the eyes or ears
into understandable language. It does not result from vision or
hearing problems.
15. TYPES OF DYSLEXIA
A.) PRIMARY DYSLEXIA- This type of dyslexia is a
dysfunction of, rather than damage to, the left side of the brain
(cerebral cortex) and does not change with age. Individuals with this
type are rarely able to read above a fourth-grade level and may
struggle with reading, spelling, and writing as adults. Primary dyslexia
is passed in family lines through their genes (hereditary). It is found
more often in boys than in girls.
B.) SECONDARY OR DEVELOPMENTAL
DYSLEXIA
-caused by hormonal development during the early stages of fetal
development. Developmental dyslexia diminishes as the child matures.
It is also more common in boys.
16. DYSLEXIA MAY AFFECT SEVERAL
DIFFERENT FUNCTIONS
Visual dyslexia is characterized by number and
letter reversals and the inability to write symbols in the
correct sequence.
Auditory dyslexia involves difficulty with sounds
of letters or groups of letters. The sounds are perceived
as jumbled or not heard correctly
17. WHAT ARE THE SIGNS AND
SYMPTOMS OF DYSLEXIA?
Letter and number reversals are the most common warning
sign. Such reversals are fairly common up to the age of 7 or
8 and usually diminish by that time.. Difficulty copying from
the board or a book can also suggest problems. There may
be a general disorganization of written work. A child may not
be able to remember content, even if it involves a favorite
video or storybook.
18. LEARNING
DISABILITIES
2.) Dysgraphia
-A learning disability that affects writing, which requires a
complex set of motor and information processing skills. Dysgraphia
makes the act of writing difficult. It can lead to problems with
spelling, poor handwriting and putting thoughts on paper. People
with dysgraphia can have trouble organizing letters, numbers and
words on a line or page.
THIS CAN RESULT PARTLY FROM:
Visual-spatial difficulties: trouble processing what the eye
sees
Language processing difficulty: trouble processing and
making sense of what the ear hears
19. YOUNG CHILDREN

20. LEARNING
DISABILITIES
3.) Dyscalculia
-A condition that affects the ability to acquire
arithmetical skills. Dyscalculic learners may have
difficulty understanding simple number concepts, lack
an intuitive grasp of numbers, and have problems
learning number facts and procedures. Even if they
produce a correct answer or use a correct method,
they may do so mechanically and without confidence.’
-Dyscalculia is like dyslexia for numbers
21. TYPICAL SYMPTOMS OF
DYSCALCULIA
Counting: Dyscalculic children can usually learn the sequence of
counting words, but may have difficulty navigating back and forth,
especially in twos and threes.
Calculations: Dyscalculic children find learning and recalling
number facts difficult. They often lack confidence even when they
produce the correct answer. They also fail to use rules and
procedures to build on known facts. For example, they may know
that 5+3=8, but not realise that, therefore, 3+5=8 or that 5+4=9.
Numbers with zeros: Dyscalculic children may find it difficult
to grasp that the words ten, hundred and thousand have the same
relationship to each other as the numerals 10, 100 and 1000.
22. TYPICAL SYMPTOMS
OF DYSCALCULIA
Measures:
Dyscalculic children often have difficulty with
operations such as handling money or telling the time.
They may also have problems with concepts such as
speed (miles per hour) or temperature.
Direction/orientation:
Dyscalculic children may have difficulty
understanding spatial orientation (including left and
right) causing difficulties in following directions or with
map reading.
