Problem Statement
Solomon-Rice & Soto 2011
Toddlers and preschoolers who benefit from AAC often demonstrate expressive language delays in combination with severe speech impairments.
This population uses unaided and aided multi-modal methods to communicate.
This population often requires language intervention to facilitate vocabulary production.
What language intervention strategies should be implemented to facilitate vocabulary production with toddlers and preschoolers who are multi-modal communicators?
Purpose of Presentation
Solomon-Rice & Soto 2011
This presentation will describe explicit and validated intervention strategies which support
vocabulary productions in toddlers and preschoolers who use multi-modal AAC through:
Systematic vocabulary selection
Evidence-based language intervention approaches
Inclusion of care-giver training
Selection of appropriate contexts for intervention
Representational considerations
Systematic Vocabulary Selection
Solomon-Rice & Soto 2011
Consider coverage vocabulary within the child’s receptive language repertoire that is not produced (Vanderheiden & Kelso, 1987).
Include core vocabulary (Banajee, Decarlo, & Stricklin, 2003).
Include fringe vocabulary (Beukelman & Mirenda, 2005).
Systematic Vocabulary Selection continued…
Solomon-Rice & Soto 2011
Include words that are frequently produced by typically developing and late talking toddlers and preschoolers (Rescorla, Alley, & Christine, 2001).
Incorporate caregiver tools such as the MacArthur-Bates Communicative Development Inventories, Second Edition (Fenson, et al., 2007).
Evidence-Based Language Intervention Approaches
Solomon-Rice & Soto 2011
Focused Stimulation SLP provides multiple models of targeted vocabulary or
grammatical constructions within meaningful contexts a minimum of ten times.
Child has multiple opportunities to produce targeted vocabulary/grammatical constructs.
Naturalistic contexts promote production of targeted language (Cleave & Fey, 1997).
What Research Tells Us about Focused Stimulation
Solomon-Rice & Soto 2011
Cyclical goal attack strategies facilitated
learning specific grammatical forms; SLP
treatment more consistent than parental treatment
(Fey, et al. 1993; Fey, et al., 1997).
Structured routines and theme based activities
facilitated vocabulary and 2-3 word phrases in
toddlers (Robertson & Ellis Weismer, 1999).
Story-book reading activities facilitated
production of grammatical morphemes through
modeling and recasts with three school-aged children
who used aided AAC (Binger, Maguire-
Marshall, & Kent-Walsh, 2011).
Focused Stimulation with Toddlers Who Use Multi-Modal AAC
Solomon-Rice & Soto 2011
Vocabulary is targeted that toddlers comprehend but do not produce.
SLP models targeted vocabulary 10 times during child-centered, interactive play within a natural context.
Exploratory research suggested toddlers who use multi-modal AAC might benefit from focused stimulation; two of three toddlers demonstrated improved vocabulary production (Solomon-Rice & Soto, in process).

Aided AAC Modeling
Solomon-Rice & Soto 2011
SLP points to a graphic symbol on a child’s AAC device while simultaneously producing the corresponding spoken word during natural communication exchanges (Goosens’, 1989).
What Research Tells Us about Aided AAC Modeling
Solomon-Rice & Soto 2011
SLP pointed to and labeled 12 graphic symbols during scripted
routines with a preferred activity; three cognitively impaired preschoolers demonstrated
increased symbol comprehension and production (Harris & Reichle,
2004).
SLP pointed to and labeled two symbols, followed by production of
a grammatically complete sentence, during imaginative play scenarios; four of five preschoolers
consistently produced multi-symbol messages (Binger & Light,
2007).
AAC Modeling with Toddlers Who Use Multi-Modal AAC
Solomon-Rice & Soto 2011
Vocabulary is targeted that toddlers comprehend but do not produce.
SLP models targeted vocabulary 10 times while simultaneously modeling toddler’s unaided or aided AAC system (e.g. manual sign, graphic symbols) during child-centered, interactive play within a natural context.
Exploratory research suggested two of three toddlers who used multi-modal AAC demonstrated improved vocabulary production (Solomon-Rice & Soto, in process).

Inclusion of Caregiver Training
Solomon-Rice & Soto 2011
Responsivity Education
Child oriented behavior - following the child’s lead
Interaction promoting strategies
Language modeling strategies (Manolson, 1992)
What Research Tells Us about Responsivity Education
Solomon-Rice & Soto 2011
Decreased directiveness and increased responsiveness with
mothers and their preschoolers with developmental and
language delays (Girolametto, 1988; Tannock, et al. 1992)
Improved mother-child interactions for initiation,
responding, and requesting with toddlers diagnosed with cerebral palsy (Pennington, et
al., 2009)
Responsivity Education and Aided AAC Modeling
Solomon-Rice & Soto 2011
Caregivers instructed in language facilitation techniques
Open-ended question asking with expectant delays
Modeling desired productions on child’s AAC device
Responding to child’s productions using AAC imitation, expansion, and recasts (Binger, Kent-Walsh, Berens, Del Campo, & Rivery, 2008; Rosa-Lugo & Kent-Walsh, 2008)
What Research Tells Us about Responsivity Educationand Aided AAC Modeling
Solomon-Rice & Soto 2011
Caregivers consistently used RE and AAC modeling
strategies during story book reading
activities across studies.
Three preschoolers increased multi-
symbol productions; more time was needed
to produce 2-word phrases using a
communication board versus a VOCA
(Binger, et al. 2008).
Two school-aged children increased
communicative turn-taking and expressed
novel semantic concepts (Rosa-Lugo
& Kent-Walsh, 2008).
Six preschool and school-aged children
increased communicative turn-
taking and use of different semantic
concepts (Kent-Walsh, Binger, & Hasham, 2010).
The System for Augmenting Language for Toddlers with AAC Needs
Solomon-Rice & Soto 2011
Vocabulary is targeted that toddlers neither comprehend nor produce.
Caregivers are coached in naturalistic intervention strategies and one of three treatment conditions:
augmented input
augmented output
spoken communication only with no use of AAC
Augmented input consists of VOCAs and gesturing but no signing.
Naturalistic intervention strategies are used to learn targeted vocabulary (Romski, et al., 2010).
What Research Tells Us about the System for Augmenting Language with Toddlers
Solomon-Rice & Soto 2011
Toddlers in the augmented input and output treatment groups produced significantly more augmented and spoken vocabulary.
Toddlers in the augmented output group were more likely to produce spoken words at session 18 and maintain the words at session 24 in comparison to the other two groups (Romski, et al., 2010).
Solomon-Rice & Soto 2011
“Word learning is the product of the active mind of a child. Children strive to learn the words that can express what they have in mind….A language will never be acquired without engagement in a world of persons, objects and events (Bloom 2000 p. 44).”
The Context for Early Word Learning
Solomon-Rice & Soto 2011
Engagement: Intentional Attention for the purpose of deriving and sharing MEANING
Meaning: what is perceived as relevant to the individual (based on prior knowledge, needs and interests)
Solomon-Rice & Soto 2011
Children acquire language through interaction with others as they engage in shared activities
Experience is the encounter of the child with aspects of the environment. It involves attention, perception, action and interaction
Experiences are filtered through language into verbalized events. A verbalized event is constructed online in the process of speaking (Slobin, 1996)
EARLY Word Learning in AAC:Putting it all together
Solomon-Rice & Soto 2011
It is not about lists. It is about EXPERIENCE and PARTICIPATION with true communicative responsibility;
The process of early word learning changes in the course of development: From expressing owns intentions to understanding
others’
From highly referential to conversational and “storied”
So, what does it take to learn a word?
Solomon-Rice & Soto 2011
constraints/principles theories social pragmatic view
associationisticaccounts
the emergentistcoalition theory
Constraints/Principles Theories
Solomon-Rice & Soto 2011
Emphasize the importance of cognitive biases or assumptions that children make in early word acquisition :
reference
extendibility
whole object bias
conventionality
categorical scope
novel name-nameless categories
Social/Pragmatic Theories
Solomon-Rice & Soto 2011
Children use social cues that point to referential intent (Tomasello).
Adults talk about objects, actions and events that children are focused on, thereby producing language that is relevant to the child’s interests (L. Bloom). relevance discrepancy elaboration
Associationistic Theories
Solomon-Rice & Soto 2011
Children map word to meaning through association of the most frequently word used to the most salient referent : perceptual saliency
association
frequency
Emergentist Coalition Model
Solomon-Rice & Soto 2011
• Children recruit a “coalition” of social, attentional, cognitive and linguistic cues to learn the meaning of new words.
• The cues for word learning “change their weights” over development.
Language Acquisition Theories – Common Ground
Solomon-Rice & Soto 2011
Children must have access to linguistic units and must be sensitive to the possible relations between those units to learn grammar.
Children are born with sensitivities to language-relevant data properties in the input (Hirsh-Pasek & Golinkoff, 1996).

Grounding Aided Word Learning
Solomon-Rice & Soto 2011
Attentional Cues perceptual saliency temporal contiguity
Social Cues social eye gaze Social context
Linguistic Cues morpho-syntax
Cognitive Cues
Attentional Cues in Aided Word Learning
Solomon-Rice & Soto 2011
Perceptual Saliency
Temporal Contiguity highly referential and contextualized intervention
words cannot be taught in isolation
heavy emphasis on observable objects, properties and events
Word Learning in AAC: Social Cues
Solomon-Rice & Soto 2011
Pictures have symbolic potential when presented with pragmatic cues.
The adult’s communicative intent
seem to be the strongest cue in how a child
interprets the meaning of a picture under
different conditions.
Word Learning in AAC: Linguistic Cues
Solomon-Rice & Soto 2011
Language develops; AAC must be learned (Smith, 2006).
Children need a range of lexical types and grammatical markers in order to realize different types of clauses and phrases (Kaul, 2003).
Solomon-Rice & Soto 2011
When grammatical markers are provided, word order matches environmental language (Nakamura et al., 1998) even with nonreaders (Koul, 2003)
Word Learning in AAC: Cognitive Cues
Solomon-Rice & Soto 2011
Words direct children’s attention to aspects of reality that get encoded in their native language, eg., tight of fit, spatial preposition, path of motion.
In Conclusion
Solomon-Rice & Soto 2011
To Facilitate Vocabulary Production in Toddlers and Preschoolers:
Systematically select vocabulary within the child’s receptive repertoire; include both core and fringe vocabulary; include vocabulary typically produced by toddlers and preschoolers; and include caregiver input in vocabulary selection.
Evidence-based research supports the use of focused stimulation, aided AAC modeling, and caregiver training in responsivity education combined with AAC modeling as effective intervention approaches.
Children need participants in meaningful experiences and access to linguistic systems to learn the meaning of words.
