A second difference between regular and maintenance programme planning is that maintenance programmes aim to maintain the acquired behaviour and are therefore likely to focus more on skills and reducing the barriers to maintain behaviour.
This may mean acquiring behaviours appropriate to a new biological environment: when moving into a new habitat, with unknown plants and animals, it is best to eat the foods the locals eat, for one thereby avoids poisoning.
Impaired function of the mesolimbic dopamine system can cause ADHD symptoms of delay aversion, hyperactivity in a familiar environment, impulsiveness, deficient sustained attention, increased behavioural variability and failure to extinguish previously acquired behaviour [ 4].
It has been suggested that deficient reinforcement of appropriate behaviour and/or deficient extinction of previously reinforced behaviour can give rise to ADHD symptoms of delay aversion, hyperactivity in a familiar environment, impulsiveness, deficient sustained attention, increased behavioural variability and failure to extinguish previously acquired behaviour [ 4].
In this approach, emotional problems are thought to result from faulty acquired behaviour patterns or the failure to learn effective responses.
Moreover, it considers performing behaviour and receiving feedback to be important strategies for acquiring behavioural skills.
Most animals have evolved several sophisticated systems of 'extrinsic motivations' (EMs) that guide them to acquire behaviours allowing them to maintain their bodies, defend against threat, and reproduce.
The indicators here focus on knowledge gained, attitudes changed, skills acquired, and behaviours adopted as a result of nursing interventions.
One hypothesis advanced to account for the greater retentivity of psychomotor behaviour, as compared to that of newly acquired verbal behaviour, is that nonverbal actions are more often overlearned and are less susceptible to proactive interference (i.e., competition arising from things learned in the past).
Migration has developed independently in different groups of birds and does not appear to require genetic change; some birds have acquired migratory behaviour since the last ice age.
