In the introductory chapters of their book, M.O.R.E: Integrating
the Mouth With Sensory and Postural Functions – March 1, 1999,
Oetter, Richter and Frick describe three stages of brain develop-
ment required for effective self-regulation [22]. These three stages
are seen as a hierarchy, in which each level must be well-estab-
lished in order for the subsequent level to develop efficiently. As
the infant progresses through these stages successfully, the pinna-
cle of development is reached in which the individual achieves ef-
fective neurological integration which supports self-mastery. This
self-mastery is required to become a well-integrated sensory-mo-
tor-cognitive and socio-emotionally competent person.
In this paradigm, the acquisition of new skills requires cycling
through earlier-achieved levels. A hiatus or interference in any of
the stages will negatively impact on subsequent levels of develop-
ment which could have lasting consequences on the individual’s
competence. If neurological integration is not achieved effective-
ly, there are likely to be cognitive, socio-emotional and physical
consequences.
*In the first order the lower brain centres are organized, such as
thalamus, hypothalamus, lower brainstem, medulla and cerebel-
lum. These areas regulate activities for survival, such as ingestion,
digestion and elimination, heart rate and cortical tone, tempera-
ture, respiration, blood pressure and the sleep-wake cycle. Here
too are integrated the functions of the endocrine, immune and ner-
vous systems.
*In the second order, the higher brain centres become organized,
notably those of the brain stem, reticular activation centre, and
cerebellum. These areas organize and integrate the sensory-motor
loops such as the suck-swallow-breathe synchrony, selective at-
tention, the righting response, reflexive babbling, and importantly
the ability to achieve, maintain and change situation-appropriate
states.
*In the final, or third order in the development of self-regulation,
the main areas of processing are of the cortex including the frontal
lobes, regulating the higher cortical functions of intention, volun-
tary goal-directed behaviour, sustained attention, communication
and organization of spaces, tasks, time and environments, such as
speech and language, scholastic skills, and socialisation.
