Communication Delays with Autism ● Individuals with autism spectrum disorders (ASD) show differences in communication development, especially in language acquisition timing and patterns (Tager-Flusberg et al., 2006). ● Early signs of impairment manifest in infancy, such as a lack of shared attention, where infants with ASD might not follow the caregiver's gaze or engage in coordinated joint attention (Adamson & Chance, 1998). ● By 18 months, typical children share attention with caregivers, but in ASD, deficits in sharing gaze and pointing are observed and used as identifying factors in ASD screenings (Baron-Cohen, Allen, & Gillberg, 1992). 2. Communication Delays with Autism ● Failure to attend to speech is an early predictor of ASD (Osterling & Dawson, 1994; Paul & Sutherland, 2005), and parents often express concerns about their children's communication and speech in the second year of life (Prelock, Paul, & Allen, 2011). ● Individuals with ASD exhibit reduced rates of communication (Paul & Sutherland, 2005) and may use speech idiosyncratically, such as in immediate or delayed echolalia (Bay, 1980b). ● Difficulties with pronouns are common in ASD, where individuals might misuse pronouns and struggle with gender distinctions (Tager-Flusberg et al., 2011). 2. Communication Delays with Autism ● If individuals with ASD use speech, it might have atypical prosody or intonation and can lack understanding of word boundaries, answering wh- questions, or interpreting the context of words (Fay, 1980a; Koegel & Koegel, 1995; Krantz et al., 1981). ● Vocalizations in individuals with ASD might be self-stimulatory and repetitive, often focused on favorite topics and lacking the ability to generalize word meanings or forms (Schuler, 1980). ● Pragmatic challenges are common, where individuals with ASD may take language literally and struggle to understand the social context in which language is used (Tager-Flusberg et al., 2011; Bogdashina, 2005). ● Literal interpretations of phrases or instructions might occur, leading to responses that don't align with the intended meaning, such as literal hopping when told to "hop to it" (Bogdashina, 2005). 3. ASD: Communication Strengths ● Some individuals with autism spectrum disorder have strengths in communication, such as visual-spatial abilities and larger vocabularies (Charlop, Greenberg,& Chang. 2011). ● Certain individuals exhibit advanced text reading skills, enabling effective text-based communication (Kupperman, Bligh, & Barouski, 1992) ● Text based communication systems can be used to facilitate interactions with other when the learners who have strong ready and visual processing skills ● Proficiency in memorizing language chunks, like songs, can aid in communication through social scripts (Lue, Schlosser). ● Incorporating activities that engage individuals with ASD, such as hugs or swings, can enhance communication strategies (Lue). 4. ASD: Cultural and Linguistic Considerations ● Caregivers use language to support children's learning in language acquisition (Wilcox & Shannon, 1998). ● Different cultures have varying beliefs about language learning, speech value, and social interaction (Wilcox & Shannon, 1998). ● Mexican American and Anglo American interactions differ, with Mexican American culture involving more triadic interactions (van Kleeck, 1994). ● Inuit culture views talkative children differently from English-speaking cultures (Owens, 1996). ● Children learn cultural conventions as they acquire language, including status, gender roles, and expressions of affection (Rice, Grinker et al., 2011). 4. ASD: Cultural and Linguistic Considerations ● Samoan children make requests based on rank, and Korean language uses suffixes for respect (Grinker et al., 2011). ● Children are aware of different communication styles among peers and adapt based on context (Rice, 1993). ● Educators must acknowledge cultural differences in communication when working with children with ASD and their families. ● Nonverbal behaviors vary across cultures, with differences in nonverbal communication methods (Garcia-Coll, 1990). ● Understanding cultural nuances in communication is crucial when working with diverse families and designing intervention plans (Kayser, Mirenda & Bopp, 2003). 5. Involving Caregivers in Planning for Goals ● Speech-language pathologists play a role in the educational team's assessment and contribute to communication goals based on inputs from all team members, including family and educators (Kalyanpur & Harry, 1999). ● Collaborative work among all educators and family members is recommended for implementing the speech-language pathologist's recommendations for learners with ASD (Kalyanpur & Harry, 1999). ● Alternatives to traditional pull-out therapy sessions, like addressing language goals within the classroom, have been explored due to concerns regarding efficacy, generalization, and naturalness of pull-out sessions (Cirrin & Penner, 1995). 6. Enhancing Educator/Caregiver Skills ● Role of teaching effective strategies to communication partners is often underestimated but studies show that when communication partners are taught use of effective communication strategies for their learners, this leads to an increase in communication of the learners (Hall & Macvean, 1997) ○ How can caregivers/educators support communication development? ■ Provide frequent opportunities ■ Contrive learner motivations ■ Acknowledge communication attempts ■ Model and embed communication in the daily routines ■ Don’t be afraid to be playful and cheerful-research shows that when communication partners are playful and animated, the learners communication is enhanced (Mahoney & McDonald, 2007) 7. ABA techniques to support Language Development ● Applied Behavior Analysis techniques to enhance communication skills: ○ Discrete Trial Training (DTT) can be used to work on prerequisite skills such as: ■ Attending to instruction (helps with attending to communication of another person) ■ For non-vocal learners, they can begin with motor imitation tasks ● ABA techniques that incorporate learner’s motivation: ○ Naturalistic Environment Teaching (NET) ○ Incidental Teaching ○ Enhanced Milieu Teaching ○ Pivotal Response Treatment (PRT) ○ SCERTS model- combines ABA strategies and social interactionist theories 7. ABA Techniques to support Language Development ● How to support Language during play: ○ Macdonald and Mitchell (2002) note shared control in play along with ■ using comments and reflections that outnumber questions can help support development of vocabulary ■ use open ended questions: ● e.g. instead of saying “are they having fun?” , state “I wonder if they are having fun” Turn Taking in communication and play: ■ wait for learner to respond to comment on your comments/open ended questions ■ when the learners make a comment, make a related comment to increase length of communication ■ Take turns in picking activities/actions in pretend play 7a) Use Functional Communication to Replace Challenging Behaviors Functional Communication Training ● All behavior is communication and any behavior that develops (even the challenging behaviors serve a function for the learner) ● during the Functional behavioral assessments, identify the function of the challenging behaviors ● based on the function of the behavior, a functionally equivalent behavior can be identified and taught. ○ Let’s discuss an example ○ Can you give an example of a challenging behavior with a specific function? What would you propose as a goal for a replacement behavior? ● As the replacement behavior is taught via functional communication training, the frequency, intensity,and duration of challenging behaviors decreases (Carr & Durrand, 1985) 7b) Use Functional Communication to Replace Challenging Behaviors Other aspects of Functional Communication training: ● Replacement behaviors must be clear and recognizable to others to be effective (Durand & Merges, 2001). ● Consequences and success reinforcement are crucial for encouraging the use of the replacement behavior (Heflin & Alaimo, 2007). ● Systematic teaching of replacement behaviors involves evidence-based strategies like prompting, prompt fading, and differential reinforcement (Sigafoos, O'Reilly, & Lancioni, 2009). ● Common replacement behaviors taught include pointing, verbal expressions, and using visuals for requests and initiating social interaction (Martin, Drasgow, Halle, & Brucker, 2005). ● Data collection is essential to ensure the selected communication skill serves the same function and is helpful for the individual (Carr et al., 1994). ● Encouraging choice-making can influence communication success, reducing disruptive behaviors and enhancing individuals' participation in their daily routines (Durand, 2012; Sigafoos et al., 2009). Any Questions?
