ABSTRACT
Children who are performing at a prelinguistic level of vocal communication present
unique issues related to successful intervention relative to the general population
of children with speech disorders. These children do not consistently use meaning-based
vocalizations to communicate with those around them. General goals for this group
of children include stimulating more mature vocalization types and connecting these
vocalizations to meanings that can be used to communicate consistently with persons
in their environment. We propose a means, motive, and opportunity conceptual framework for assessing and intervening with these children. This framework
is centered on stimulation of meaningful vocalizations for functional communication.
It is based on a broad body of literature describing the nature of early language
development. In contrast, nonspeech oral motor exercise (NSOME) protocols require
decontextualized practice of repetitive nonspeech movements that are not related to
functional communication with respect to means, motive, or opportunity for communicating.
Successful intervention with NSOME activities requires adoption of the concept that
the child, operating at a prelinguistic communication level, will generalize from
repetitive nonspeech movements that are not intended to communicate with anyone to
speech-based movements that will be intelligible enough to allow responsiveness to
the child's wants and needs from people in the environment. No evidence from the research
literature on the course of speech and language acquisition suggests that this conceptualization
is valid.
