6 BASES OF COMMUNICATIVE DEVELOPMENT
1. Neurological- development of structures and landmarks in the brain used for processing language
2. Cognitive-mental activities involved in comprehension of received information; development of symbolism
3. Perceptual-use of sensory information and previous experience to make sense of new sensory information
4. Motor-muscle movement and associated neuro-feedback5. Social –interactive processes that drive learning6. Communicative- development of communicative
intentions evident through goal directed behavior
NEUROLOGICAL FOUNDATIONS
Brain weight is associated with neural development
Early sensation and perception provide the input to increase the number and complexities of neural connections
Brain weight is tripled by 2 years of ageEARLY EXPERIENCES ARE CRITICAL!
Physiological change serves in the development of speech and language
COGNITIVE FOUNDATIONS
• Motor control
• cognition
• perception• Sensation

Cognitive development
Cognitive growth sets the pace for linguistic growth.
MOTOR FOUNDATIONS
•Stability develops in an upward progression, motor control develops in a downward progression.•Motor sequences in the body will be mirrored in the mouth.
SOCIAL AND COMMUNICATIVE FOUNDATIONS
Used to expand an individuals understanding of entities and relationships
Language is used as a social tool, motivated by improving communication and social connections
Symbolic communication is developed by associating real things to cognitive representations.
IF YOU ARE TREATED AS A COMMUNICATOR, YOU BECOME A COMMUNICATOR!
EARLY DEVELOPMENTAL TRENDS
• Typical development happens without our efforts to make it progress
• Motor skills development allows for freedom of movement
• Freedom of movement allows for exploration
• Exploration, in turn, drives development• Changes in development lead to cognitive
and psychosocial development
EXPERIENCE DRIVES DEVELOPMENT
• Experience and interaction help organize the brain and mind for cognitive growth.
• Based on commonly accepted learning theories, we know cognitive growth sets the pace for linguistic growth.
• Parallel development between cognition and language. Play is a vehicle for learning. Language and play are interdependent. Play sequences should be mirrored in a child’s language.
STEPS IN LINGUISTIC PROCESSING
4 steps in linguistic processing:1. Attention- awareness to a learning situation2. Discrimination-identification of relevant
characteristics of different inputs3. Organization- chunking related bits of
information4. Memory-recall of previously learned
information (rehearsal is required for long term storage)
LANGUAGE
Language is an accepted system of arbitrary codes and signals/symbols used to communicate ideas.
Used as a toolHas specific rulesProductive and creative

SPEECH
Expression of language with soundsHumans understand speech by~ 7 months of
ageHumans use speech productively (goal
directed behavior) by ~ 12 months of age Overlaid onto a biological system that has its
roots in a primary survival function (feeding).
THE SPEECH CHAIN
1. Speaker formulates a message
2. Motor nerves send impulses to lungs larynx and articulators
3. Sound waves are transmitted to listener’s ear (enter feedback link)
4. Listener’s ear transforms message
5. Listener’s brain decodes message
SPEECH SOUND DEVELOPMENT
Sound classes, in order of emergence, based on *norms:
vegetative sounds, cooing, vowels, babblingEarliest sounds: /p, b, m, n, h, w/ Followed by: /k, ɡ, d, t, ŋ, f, / Then:/j, r, l/Finally: /s, ʃ , ʧ , z , v, Ө, ʤ/*hypothetical children do not exist. A wide range of
variability can be seen up to 36 months of age.
WHAT IS NORMAL SPEECH AND LANGUAGE?
Development in feeding, speech, language, voice and fluency that follows predictable developmental stages at expected age ranges
Goal directed- used to “get things done”SymbolicSocial and interactiveProgression is based on refinement of sensori-
motor and cognitive skills laid down in the first 24 months.
COMMUNICATIVE TIMELINE:0-6 months
Birthsensory and motor perception

TODDLER’S RULESAuthor: Unknown
1. If I want it, it's mine 2. If it's in my hand, it's mine 3. If I can take it away from
you, it's mine 4. If I had it a little while ago, it's mine
5. If it's mine, it must never appear to be yours in any way
6. If we are building something together, all the pieces are mine
7. If it just looks like mine, it's mine 8. If I think it's mine, it's mine 9. If I give it to you and change
my mind later, it's mine 10. Once it's mine it will never belong
to anyone else, no matter what
PRESCHOOL ADVANCEMENTS

elements and word orderWORD ORDER- basic forms of English (s-v-o) and modifications to
this pattern

topic maintenance
PRE-LITERACY FACTS
Children between ages 2-3 years should be able to tell about plans, use scripts and descriptions to describe routines.
At around 4 years of age children add physical and mental states to their descriptions.
Emergent reading phases precede reading, and at around 4 years of age children begin to recognize and identify environmental print, and know the direction of reading.
Narratives have roots in early social language skills.

ATYPICAL DEVELOPMENT
When things go wrong…
Dyspraxia Language Disorder Autism
WHAT COULD GO WRONG?
Children quickly compensate for their own missing links. What initially may have appeared to be a delay may actually be a disorder hiding under the “wide range of variability in early childhood development.
Language Disorder: receptive/expressive or bothArticulation Disorders :dyspraxia, dysarthria,
phonological processing disorderAutism or Spectrum DisordersCongenital Disorders: Acquired or Degenerative Disorders
BROKEN LINKS
When skill sets do not appear when expected, we must define a delay or a disorder.
Developmental delay implies “…an impairment… in the meeting of milestones that a child should achieve by a specific chronological age.” (Taber’s Cyclopedic Medical Dictionary, 2001)
The term “disorder” implies a pathologic or abnormal condition. In other words, absence or atypical acquisition and/or presentation of a skill.
RISKS As high as 70% of children exhibiting oral language
impairments will later exhibit difficulties with literacy. Toddler and preschool language development is critical for
school success. Autism is the fastest growing childhood disorder, and is
primarily a disorder of verbal and non-verbal language. A labeling of “delay” does not necessarily mean an
absence of disorder. Excellent memory for rehearsed or rote learned skills
(colors, letters, numbers) is not the same as symbolic learning.
RED FLAGSfor AUDITORY PROCESSING
• Difficulty with phonemic awareness• Asking “what” repeatedly after directions are given, or “I
don’t know” to avoid responding• Answering wh- questions incorrectly• Using semantic substitutions (word for word)in expressive
language that cannot be explained by articulation concerns
• Evidence of increased distraction or fatigue after periods of listening
• Body language indicating “shutting out” of active or potential communicative partners
RED FLAGS for RECEPTIVE LANGUAGE
• Need for frequent repetition• Need for extra explaining before following through with
directions• Difficulty answering questions• Difficulty understanding time concepts• Difficulty understanding prepositions or spatial concepts• Difficulty with 1:1 correspondence• Difficulty organizing or categorizing• Poor eye contact during listening tasks
RED FLAGS for EXPRESSIVE LANGUAGE
• Switching or omission of pronouns (sometimes I am you and you are me and me is you)
• Omission or difficulty using spatial or time concepts• Difficulty retelling actions or events• Omission of connector or functor words (telegraphic speech)• Verb irregularity• Frequently switching topics in conversation• Overuse of rote phrases and communicative exchanges• Inability to tell about something
RED FLAGS for ARTICULATION
• Inconsistent speech sound substitutions• Immature sounding speech toward later preschool years• Irregular airflow during speech• “wet” speech• Hypernasal/hyponasal• Jaw sliding during speaking• Parent difficulty understanding speech• A child should be 80% intelligible to their primary caregiver by 3
years of age, to other listeners by 4 years of age• Messy eating, drooling, or restricted food preferences• Poor stability; open mouth posture, uncoordinated gate +
immature or disorganized speech or feeding.
RED FLAGS for VOICE
• Hoarseness or raspiness in the absence of chronic allergies or recent illness
• Loss of voice within an utterance or conversation
• Breathiness during speech• Difficulty changing pitch during speaking
RED FLAGS for FLUENCY
• Repetitions of phoneme at the beginning of a word, thought or phrase
• Episodes of stopped airflow and/or sound during speech
• Very rapid speech• Variable rate of speech• Avoidance of conversational interaction
IS IT AUTISM?
• DSM-IV (1994)Criteria for Autism requires specific characteristics that include a total of at least 6 variations and manifestations from the following categories:
• “qualitative impairment in social interaction…, qualitative impairments in communication…, restricted repetitive and stereotyped patterns of behavior, interests and activities…”
• “Delays or abnormal functioning in at least one of the following areas, with onset prior to age 3 years: (1) social interaction, (2) language as used in social communication, or (3) symbolic or imaginative play”
• “The disturbance is not better accounted for by Rett's Disorder or Childhood Disintegrative Disorder”
AUTISM vs. LANGUAGE DELAY?
Based on DSM-IV criterion, the primary difference between a language delayed/disordered child and an autistic child is that the child with Autism will demonstrate impairment in areas of social interaction and symbolic play, as well as language form, content, and/or use. A child without spectrum characteristics will still initiate and/or engage in social interactions and play routines.
AUTISM FACTS• According to Pathfinders for Autism, Maryland estimates indicate 1:142 children
are diagnosed with Autism, a complex neurological disorder. Boys are 3-4 times more likely to be diagnosed with Autism than girls. http://www.pathfindersforautism.org/aboutAutism.aspx
• According o the National Institute of Mental Health, causes of Autism have been investigated with the following results: “The Institute of Medicine (IOM) conducted a thorough review on the issue of a link between thimerosal (a mercury based preservative that is no longer used in vaccinations) and autism. The final report from IOM, Immunization Safety Review: Vaccines and Autism, released in May 2004, stated that the committee did not find a link. ..All these disorders are characterized by varying degrees of impairment in communication skills, social interactions, and restricted, repetitive and stereotyped patterns of behavior…Evidence points to genetic factors playing a prominent role in the causes for ASD. A U.S. study looking at environmental factors including exposure to mercury, lead and other heavy metals is ongoing.” http://www.nimh.nih.gov/health/publications/autism/complete-index.shtml
WHAT TO DO?
1. Educate yourself. Find out what is “typical”.2. Be the “eyes” of the community. Be observant for early
warning signs. 3. Document your concerns. It is hard to remember details
as time goes by.4. Interview the child in a non-threatening way. Many
children are aware of their own weaknesses.5. Come alongside parents who suspect their child has a
problem and direct them to community resources.6. Use community resources. Pediatricians, Child Find, and
private practice specialists can help.
ADDRESSING CONCERNS WITH PARENTS
Be prepared. Have all of your observations, papers, and examples ready. Plan how you want the meeting to go.
Educate yourself. Consult a speech-language pathologist about concerns you may have.
Make an approach. Ask the parent when would be a good time to talk about some observations your have noticed in your setting.
Use sensitivity. No-one wants to be told their child is different or irregular. Chose words like “I noticed”, or “based on classroom performance/behavior”, or “lets err on the side of caution and have [concern] ruled out”.
Emphasize the importance of early intervention! Labels can drop off with early and appropriate intervention.
