What is the prelinguistic stage?
Newborn Period Preintentional period (1-8 months) Prelinguistic communication (9-18
months)
![Page 3: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/3.jpg)
Risk factors for infants
Prenatal Factors– maternal drug or alcohol abuse– exposure to toxins or in utero infections
Prematurity– low birth weight associated with developmental
delay– susceptibility to illness– respiratory difficulties– less interaction early on
![Page 4: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/4.jpg)
Risk factors (continued)
Genetic and congenital disorders– number of syndromes that can occur– autosomal chromosomal abnormalities
(Down syndrome)– sex chromosome disorders (Kleinfelter’s
syndrome)– craniofacial disorders– metabolic disorders

Child Behavior and Development
Assessment should be to determine the current strengths and needs– Identify what risks the infant faces– Evaluate level of infant’s physiological
organization i.e. How much stimulation and handling can the child tolerate? What is the most comfortable position for stimulation?
![Page 13: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/13.jpg)
Management of Behaviour & Development
Suggest ways to counteract low levels of language and interactive stimulation in ICU
Advocate oral development and stimulation
![Page 14: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/14.jpg)
Assessment of Parent-Child Communication
Assessing infant readiness for communication– Educate parents about stages - Turning in,
coming out, reciprocity Assessing parent communication and
family functioning– Discuss the parents concerns
![Page 15: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/15.jpg)
Management of Parent-Child Communication
Inform parent about different states the infant may be exhibiting (see Table 7-3)
Encourage parental interaction when the infant is ready – look at, handle, talk to the baby
Help parent identify end of interaction– wait for signals of interaction like eye gaze– watch for signals of distress
![Page 16: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/16.jpg)
Preintentional Infants - 1-8 mos
Preintentional - infants have not yet developed cognitive skills to represent ideas in their mind and pursue goals
Perlocutionary (Bates, 1976)– infants do not intend any particular
outcome by their behaviour– adults act as if they do (normal and impt
for communication development)
![Page 17: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/17.jpg)
Assessment and Intervention for Preintentional Infants
Feeding and oral motor development Hearing conservation and aural rehab Infant behaviour and development Parent-child communication
![Page 18: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/18.jpg)
Assessment of feeding and oral motor development
Feeding assessment - observe new feeding patterns– integrating sucking with jaw movements– chewing– rotary jaw movements– tongue lateralization– sustained bite
![Page 19: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/19.jpg)
Assessment of feeding and oral motor development
Vocal assessment (see Table 7-4, p 205)– observe child and ask parent about vocal
behaviours– use corrected gestational age - age -weeks
premature = CGA– observe sound play, consonants,
intonational changes, babbling
![Page 20: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/20.jpg)
Management of feeding and oral motor behaviour (1-8 mos) Feeding
– continue oral stimulation– introduce solid foods– see Box 7-2, p 207
Vocal Development– talk and babble to baby– imitate any non-cry vocalization– use “baby-talk”– use toys
![Page 21: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/21.jpg)
Hearing in preintentional period
Encourage assessment by audiologist Counsel regarding otitis media and
signs of otitis media such as pulling on ear, fussing
![Page 22: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/22.jpg)
Child Beh’r & Dev’t (1-8 mos)
Assessment– Involves general assessment of development– Instruments available include:
• Bayley Scales of Infant Development
• Vineland Adaptive Behavior Scales
• Receptive-Expressive Emergent Language Scale
• Sequenced Inventory of Communication Development (SICD)
• Rossetti Infant-Toddler Language Scale
![Page 23: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/23.jpg)
Child Beh’r & Dev’t - Management General motor and cognitive stimulation Home-Based Programs
– activities should be performed in communicative manner
– parent advocate
![Page 24: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/24.jpg)
Parent-Child Communication
Assessment– Formal instruments– Informal observation
• responsiveness to child’s cues of readiness and unreadiness to interact
• choice of objects and activities• language stimulation and responsiveness
(cooing, babbling, responding• encouragement of joint attention
![Page 25: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/25.jpg)
Communication - Management
Act as a support and encourage parent Paul suggests three main aspects:
– Increase awareness of infant communication patterns
– Provide Instruction and modeling of adult-infant communication
– Help parents self-monitor
![Page 26: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/26.jpg)
Awareness of comm. patterns
Explain that it may be difficult to interact with an unresponsive infant
Make communication enriching and responsive– provide visual, auditory, tactile cues to engage
baby– allow infant to explore novel stimuli
Explain interactive pattern of infants– educational videos
![Page 27: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/27.jpg)
Modeling Interactive Beh’s
Turn-taking and imitation– ensure baby is ready to interact– use smiles and vocalisations to elicit infant
behaviour– wait for the infant to initiate– imitate it and then wait for infant to do
something else– vocalization and imitation of vocalization
should be especially encouraged
![Page 28: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/28.jpg)
Interactive Behaviours
Joint Attention Routines– identify the infant’s focus and share
attention to that– make a comment or gesture about what
the baby is looking at or doing– peekaboo– choral vocalization
![Page 29: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/29.jpg)
Interactive Behaviours
Establishing anticipatory sets Playing baby games
– provide the baby with predictable series of sounds and actions
– basis for script development– use baby games that the family have used
before and/or are culturally appropriate
![Page 30: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/30.jpg)
Interactive Behaviours
Self-monitoring skills– video-taping sessions– ensure a non threatening environment for
the parents
![Page 31: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/31.jpg)
Assess’t and Treatment at Prelinguistic Comm. Stage (9-18) Infants become intentional
communicators Illocutionary stage (Bates, 1976) - child
expresses intention through signals
![Page 32: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/32.jpg)
Assessment
Play assessment (eg. Symbolic Play test) Observe play
– recognition of common objects (brush, phone)– engages in simple play schemes
Is any functional communication present– attempts to request objects or actions– eliciting attention
![Page 33: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/33.jpg)
Management
If child is expressing some communicative intent-– scaffold (e.g. break routines)– vocalise the child’s demands– shared book-reading
• joint attention to pages• stop and wait for child to respond
– Communication temptations (see box 7-3)
![Page 34: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/34.jpg)
Management (cont’d)
Facilitate comprehension– baby games (e.g. show me your nose,
ears, etc)
![Page 35: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/35.jpg)
Management (cont’d)
If the child is not showing intentionality-– provide intensified input (book reading, lots
of parallel talk, joint attention activities)– improve comprehension skills– encourage vocalization– respond to the child’s actions and
initiations
![Page 36: Assessment and Intervention in the Prelinguistic Period Paul, R. (1995). Language disorders from infancy through adolescence. Chapter 7](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e1b5503460f94b09c2d/html5/thumbnails/36.jpg)
Considerations for older prelinguistic children Feeding and oral motor development Hearing conservation and aural
rehabilitation Intentionality and communication
– symbolic systems of communication
