Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2B Objectives After completing this session, participants will 6. describe six modes of nonlinguistic/ prelinguistic communication, and explain how visual impairments may prevent children from engaging in typical nonlinguistic/prelinguistic communicative behaviors. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2C Objectives After completing this session, participants will 7. describe the potential impact of visual impairments on nonlinguistic/prelinguistic communication, including the development of idiosyncratic communicative behaviors of children with visual impairments and additional disabilities. 8. describe the potential impact of visual impairments, with and without additional disabilities, on language development. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2D Seven Levels of Communicative Competence As children develop, they become more competent at communicating and progress through seven levels of competence. Rowland & Stremel-Campbell, 1987 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2E Levels I and II • Level I: Pre-intentional behavior Reflexive behavior that reflects the child’s state (e.g., hungry, sleepy) • Level II: Intentional behavior Behavior is intentional but not intended to communicate At these levels, caregivers interpret behaviors as communicative although the child does not intend to communicate. Rowland & Stremel-Campbell, 1987 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2F Levels III and IV • Level III: Nonconventional presymbolic • communication Nonconventional gestures used in an attempt to affect caregiver’s behavior Examples: laugh, babble Level IV: Conventional presymbolic communication Conventional gestures used to influence caregiver’s behavior Examples: wave, point, nod, kiss Rowland & Stremel-Campbell, 1987 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2G Levels V and VI • Level V: Concrete Symbolic Communication Use of concrete symbols that share features of the referent Examples: make animal sounds, use depictive gestures (e.g., arms up for ‘hold me’) • Level VI: Abstract Symbolic Communication Limited use of abstract symbols (e.g., spoken words) Example: speech or sign used one word at a time Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Rowland & Stremel-Campbell, 1987 Communication Development & Impact of VI 2H Level VII • Level VII: Formal Symbolic Communication Rule-bound (adult-like) use of abstract communication system Example: combining two or more words to communicate Rowland & Stremel-Campbell, 1987 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2I Receptive Communication in Infants • Infants attend to • • human voices and become excited when parents approach. Infants begin to smile when adults smile and calm when picked up while crying. Infants respond to their name by 6 months. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Adamson, 1996 Sachs, 1997 Communication Development & Impact of VI 2J Nonintentional Communication • Newborn infants do not • intend to communicate—they simply react. Nonintentional communication dominates the first 6 to 8 months of life as children learn to engage in behaviors that elicit adult responses. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Owens, 2001 Sachs, 1997 Communication Development & Impact of VI 2K Expressive Communication in Infants Examples of early nonlinguistic communication include • crying, • laughing, • cooing, and • babbling. Owens, 2001 Sachs, 1997 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2L Symbolic and Nonsymbolic Communication Language is symbolic—based on sounds that represent objects, people, events, actions, etc. Nonsymbolic communication includes • vocalizations (e.g., babbling, crying), • gestures, • facial expressions, and • social referencing (i.e., looking to an adult to determine how to respond to a novel situation). Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2M Nonsymbolic Communication Other forms of nonsymbolic communication include • joint visual attention (i.e., looking at the same object that an adult looks at) and • responsiveness to a communicative partner. Infants use nonsymbolic communication • to gain an adult’s attention and • to express desires and needs. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2N Individual Differences in Development • Children with and without disabilities vary • • considerably in the ages at which they attain communication and language milestones. The ages associated with milestone acquisition in typically developing children provide a reference point only, and should be viewed cautiously. Children with disabilities, and particularly those with multiple disabilities, may show tremendous variability in the ages at which they attain developmental milestones. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2O First Words • 10 to 18 months: first true word • 10 to 18 months: points to an object and uses word approximation • 12 to 18 months: vocabulary of 3 to 20 words; 50% of words are nouns • 12 to 18 months: uses phrases such as “All gone” and “Want more”; begins using verbs and adjectives Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2P Expressive Language of the Toddler • 2 years: approximately 65% of speech is intelligible, with ~50 recognizable words • 2½ years: 70% of speech is intelligible, with ~200 words Answers Where?, What . . .doing?, and What do you hear? questions Uses two-word phrases including negation (e.g., “No bed”), possessives (e.g., “Mommy car”), and pronouns (e.g., “Me Janey”) Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2Q Expressive Language of the Toddler • 3 years: 80% of speech is usually intelligible, with ~500 words Asks simple questions and repeats sentences Uses articles such as “a” and “the” Uses contractions and –ing endings 25% of utterances are nouns and 25% are verbs Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2R Receptive Language of the Toddler 12 to 18 months • Follows simple one-step commands • Points to one to three body parts • Identifies one or two objects from a group of objects Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2S Receptive Language of the Toddler Between 18 and 24 months • Comprehends about 300 words • Interested in listening to stories Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2T Receptive Language of the Toddler • 2½ years Comprehends 500 words Listens to 5-10 minutes of a story Carries out two related commands • 3 years Comprehends 900 words Knows concept words such as in/on and big/little Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2U Elements of Language • Phonology—rules that govern the use of speech sounds • Morphology—rules that determine the internal organization of words • Semantics—rules that determine the meaning of words and word combinations Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2V Elements of Language • • Syntax—rules that govern the form or structure of a sentence Pragmatics—rules that governs how a given language is used in different social contexts and environments Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2W Attachment Attachment describes the emotional connection between people in intimate relationships such as parent and child. Zeanah & Boris, 2000 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2X Attachment Examples of behaviors that encourage attachment are • • • • crying, smiling, crawling toward a caregiver, and clinging to a caregiver. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2Y Attachment and Visual Impairment • Attachment behaviors may be delayed, occur less frequently, or occur with less clarity, in children with visual impairments. • Caregiver responsiveness is the most important factor in encouraging attachment with children with visual impairments. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Fazzi, 2002 Warren & Hatton, 2003 Communication Development & Impact of VI 2Z Attachment and Visual Impairment Responsiveness includes reading children's signals to know when they want to interact, when they are tired or overstimulated, and what interests the child. Fazzi, 2002 Warren & Hatton, 2003 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2AA Facilitating Attachment • Talk to children before picking them up. • Give children time to adjust to new situations. • Look for subtle responses such as changes in breathing or body posture. • Allow children to touch your face in order to recognize you. • Carry infants in cloth baby carriers (chest or back) during daily routines and when participating in community activities. Ferrell, 1985 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2BB Facilitating Nonlinguistic/ Prelinguistic Communication Turn-taking—parents wait for child to act, then imitate, and follow child’s lead. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2CC Facilitating Nonlinguistic/ Prelinguistic Communication • Social routines—teach turn-taking and patterns while providing consistency for a communicative exchange. • Interactive matching—parents adjust their interaction style to match children’s pace, level of functioning, and lead. • Environmental arrangement—can prompt children to use gestures or vocalizations to secure toys. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2DD What is concept development? • A concept is a • general idea that develops through repeated experiences with specific events. Children need repeated experiences with specific examples to generalize concepts. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Warren & Hatton, 2003 Communication Development & Impact of VI 2EE Movement • Children with visual • • impairments often have delays in motor development. Delayed motor development impedes movement and exploration. Lack of exploration directly impacts Adelson & Fraiberg, 1974 concept development Jan, Sykanda, & Groenveld, 1990 and communication. Palazesi, 1986 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2FF Concept Development • Provide children with multiple active experiences to build concepts. • Children learn concepts through natural experiences and play. • Concepts are best learned within functional activities. • Children with visual impairments are often delayed in concept development due to loss of visual input and delays in self-initiated movement. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2GG Promoting Concept Development • Take advantage of naturally occurring events (e.g., accidents, a dump truck on the street). • Expose children to concepts in the home and in the community. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2HH Six Modes of Nonlinguistic/ Prelinguistic Communication There are six modes of nonlinguistic/prelinguistic communication between infant and caregiver. • Proxemic—movement toward or away from the caregiver • Kinesic—recognition of facial expressions • Gestural—child reaching toward caregiver Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2II Six Modes of Nonlinguistic/ Prelinguistic Communication There are six modes of nonlinguistic communication between infant and caregiver. • Ocular—looking behaviors shared between infant and caregiver • Tactile-kinesthetic—touching between infant and caregiver • Vocal—vocalizations from the infant to the caregiver, combines vision and hearing Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2JJ Influence of VI on Modes of Nonlinguistic Communication • All, except tactile• • kinesthetic, rely partly or entirely on visual input. Visual impairments limit or alter other modes of communication. Visual impairments may decrease children’s communicative initiations about objects in the environment. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Sapp, 2001 Communication Development & Impact of VI 2KK Key Issues From Research • Children with visual impairments engage in nonlinguistic communication that is interpreted by and responded to by their mothers. • The repertoire of communicative behaviors of children with visual impairments is more limited than their peers. Preisler, 1991 Rowland, 1984 Urwin, 1984 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2LL Key Issues From Research • Mothers of children with visual impairments engage in patterns of communication that differ from mothers of typically sighted children. • Children with visual impairments smile, coo, and attempt to imitate adult speech at similar ages as children with sight. Preisler, 1991 Rowland, 1984 Urwin, 1984 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2MM Key Issues From Research • • Children with visual impairments use imitation to elicit communicative responses from mothers, and they respond to their mothers’ use of routines for communication. Children who are blind do not demonstrate conventional gestures (e.g. showing, waving, and nodding). Preisler, 1991 Rowland, 1984 Urwin, 1984 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2NN Maternal Interactions and VI Mothers of children with visual impairments • are more likely to be physically involved and to engage in controlling behaviors, • modify common interactive routines to encourage child participation, and • use routines that involve social play or imitation and are less likely to be action based. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Behl et al., 1996 Chen, 1996 Communication Development & Impact of VI 2OO Children With VI and Additional Disabilities • Parents face additional challenges in interpreting nonintentional communication. • Mothers engage in fewer positive and more negative interactions with children with multiple disabilities than do mothers of sighted children. Baird et al., 1997 Rogers & Puchalski, 1984 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2PP Children With VI and Additional Disabilities • Mothers of children who have multiple disabilities identify fewer behaviors as communicative. • Children often vocalize less, are more negative in their vocalizations, and develop idiosyncratic ways of communicating. Baird et al., 1997 Rogers & Puchalski, 1984 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2QQ Development of Language in Children With VI • Phonology and morphology develop in children with VI at the same rate as in sighted children. • Semantics: The first 50 words of children with VI have more specific nouns and fewer general nouns than those of sighted children. Children with VI are less skilled at verbal classification than are sighted children. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2RR Pragmatics • Sighted children learn pragmatics through communicative/social interactions with adults and other children. • Children with visual impairments develop social smiles at the same time as typically developing children. Conti-Ramsden & Pérez-Pereira, 1999 Rogers & Puchalski, 1986 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2SS Pragmatics Children with visual impairments • ask more questions, • use questions to request an action from communication partners, and • rely more on routines, repetition, and imitation than do sighted children. Erin, 1986; 1990 Pérez-Pereira & Castro, 1992; 1997 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2TT Pragmatics • During communication, children with visual impairments have fewer verbal turns and more nonverbal turns than do their sighted peers. • Mothers of children with blindness initiate more communication than do mothers of children with low vision. Conti-Ramsden & Pérez-Pereira, 1999 Rogers & Puchalski, 1986 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2UU Pragmatics • Children with visual impairments have difficulty learning to read body language. • Children with multiple disabilities initiate communication less frequently, and communicative partners spend less time facing the child. • Visual impairments may impede children’s ability to understand nonverbal aspects of communication. Kekelis & Prinze, 1996 Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Moore & McConachie, 1994 Communication Development & Impact of VI 2VV Nonverbal Communication and Visual Impairments After speech develops, many aspects of communication are still nonverbal and can include • • • • turn-taking, body language, initiations, and Hala, 1997 responsivity. Early Intervention Training Center for Infants and Toddlers With Visual Impairments FPG Child Development Institute University of North Carolina at Chapel Hill August 1, 2005 Communication Development & Impact of VI 2WW Children With Multiple Disabilities • Children with multiple disabilities have delays • in language development. Children with multiple disabilities may use alternative systems including touch cues, augmentative communication devices (high- and low-tech), signing, and hand-in-hand signing.
