Activity Based Instruction
Goal: to improve children’s acquisition and use of important motor, social, affective, communication, and intellectual behaviors that, in turn are integrated into response repertoires that are generative, functional, and adaptable. (Bricker & Cripe, 1992).
• Generative repertoire: responses that can be adapted to meet novel or challenging conditions.
• Functional repertoire: responses that are useful in the natural environment.
• Adaptable repertoire: responses that can be modified accommodate the physical or social restraints of a situation.

Theoretical Basis of ABI
• Both the immediate and larger socio-cultural environment influence a child’s development.
• The child must be actively engaged to learn.
• Children learn best in functional and meaningful activities.
“Activity, culture, & concept are interdependent..”
Brown & Duguid, 1989.

Characteristics of Instruction
The experiences provided to children are child-initiated, routine, or planned activities that:A. Emphasize environmental
transactionsB. Are meaningful and
functionalC. Are developmentally
appropriateD. Are designed to produce
change in repertoires

Differences Between ABI & Other Naturalistic Approaches
1 Although individual children’s objectives are recognized and coordinated within activities, the focus is directed to the group as opposed to the individual.
2 ABI addresses the global needs of the child, not just language.
3 The primary vehicle for training is the use of activities that children choose or enjoy.

Guidelines for the AB Interventionist
1 Permit the child to initiate activities whenever possible.
2 Follow the lead or initiation unless the behavior is too repetitive, regressive, or does not lead toward goals.
3 Introduce planned activities that have meaning.
4 Monitor involvement and interest in activities, and change or rearrange when motivation wanes.
5 Constantly observe behavior and act on opportunities to enhance their problem solving skills.

Designing an ABI Lesson/day
1 Describe children by: age, abilities, strengths and weaknesses
2 Identify priority goals3 Describe setting (including resources and
changes throughout the day)4 Use observation to highlight individual:
5 Build an activity by skill matrix6 Develop an antecedent/behavior
consequence schedule (identify common antecedents, consequences, and reinforcers)
7 Establish a systematic monitoring system

Preterm Infants
• Definition: fetuses who develop in extrauterine settings at a time when their brains are growing more rapidly than at any other time in their life.
• Need care available only in the specialized, medical-technology environments of new-born intensive care units (NICUs).
• NICU patients are at high risk for: organ impairments (including lung disease or bronchopulmonary dysplasia), intraventricular hemorrhage, ROP, and necrotizing enterocolitis.
• Even healthy preterm infants are at increased risk for future problems:
Specific LD low IQs self-regulatory problems.
Visual motor problems language disorders.
ADD/ADHD behavior disorders.

Brain Development
• 6-weeks : human cortex begins to develop and neurons are “created.”
• 8 to 24-weeks : most neuron have developed and migrated to specific locations.
• 24 weeks: neuronal maturation and organization increase dramatically.
• 7-weeks: first synaptic contacts are established.
• End 2nd trimester: increase in brain weight and head shape; Fetal behavior becomes more complex:
• 40 weeks: myelinization peaks, but continues until the child is 9-years-old.
10
1st Generation NICU Interventions
• Counteraction of sensory deprivation by extra stimulation.
• Prevention of disturbances in mother-infant bonding.
• Provision of compensatory experiences.
• Resolution of emotional crises of premature delivery.
• Making up for feared developmental delays.
• Improvement in parental responsiveness to infants’ deficient capacity to elicit care.
11
*Put the focus on the relationships of infants, families, and professionals
* The nature of the preterm infant in the NICU requires relationship-based care from a:
• Brain developmental
Perspective • Evolutionary
Perspective• Neurobehavioral
Perspective • Psychological
Perspective
2nd Generation NICU Interventions
12
Focus of 2nd Generation Interventions
Infants as collaborators in their own care, striving to follow a developmental trajectory
Professionals use:
Behavioral observation
Behavioral interpretation
13
Aspects of Modern NICU Care
• Consistency of caregiving• Structured day• Calm, organized pace of intervention• Support during transitions between
caregiving activities• Appropriate positioning• Individualized feeding support• Opportunities for skin-to-skin holding• Collaborative care• Quiet, soothing environment• Family comfort• Developmental support
14
Low Birth Weight Infants
• 7% of US births are LBW (<2500g)• 1% of births are VLBW (<1500g)• In US, LBW is the #1 cause of our
high infant mortality rate• Risk factors associate with LBW:
Minority status
Low SES
Low pre-pregnancy weight
Medical risks during pregnancy
Poor access to health care
preterm birth (<34 weeks gestation are often VLBW)
15
Child Development & LBW
• Overall increased rates of health, neurodevelopmental, and psychological problems.
• 3x as likely to be MR.• 2x as likely to have behavior
disorders.• 2x as likely to die before 28-
days.• Co-occurrence of LBW and
environmental disadvantage places children at highest risk for delay.
16
Components of Effective Interventions
• Intensity• Timing• Direct versus indirect• Environmental maintenance of gains:• Comprehensiveness• Attention to individual differences• Sensitivity to cultural differences
Gains are greatest in homes who are at the most environmental risk as determined by
maternal IQ or maternal education
The lower the BW, the smaller the effects of intervention on IQ
