A specific sign of an ineffective response
reflected through the interdependence
mode is the infant’s inability
to receive nurturance from central relationships.
This difficulty may be demonstrated
immediately through the infant’s
pronounced regulator activity (for
example, increased heart rate, oxygen
saturation instability, increased motor
activity, and increased behavioral distress)
particularly when confronted
with interactions involving touch. Because
the preterm infant can only communicate
nonverbally, these signs are exhibited
physiologically. It is important to
recognize that these signs are indicative
of two distinct adaptation concerns: the
easily measured, apparent physiological
instability and the interdependence (or
nurturance) ineffectiveness.
