EIBI and Lovaas (1987)

UCLA Young Autism Project (YAP) 1970-1984

Early

  • Less discrimination between environments
  • More likely to generalize and maintain treatment gains

Intensive

  • 40+ hours per week

Behavioural Intervention

  • Using Modern learning theory (Years 1-3)
  • Build complex behaviour and suppress pathological
eibi and lovaas 19873
EIBI and Lovaas (1987)

1st year: Reducing self-stimulatory and aggressive behaviour, teaching imitation, toy play, extending treatment into family

2nd year: Teaching expressive language, play with peers, extended to community (preschool)

3rd year: Teaching of appropriate and varied expression of emotions, reading, writing, arithmetic, observational learning

Neurobiology of Autism

Electrophysiological studies: EEG and ERP

  • Neural basis of face processing, non-verbal

Face sensitive ERP component (N170)

  • Large negative ERP component with a latency of 170ms

Lateralization

  • Failure of normal right hemisphere specialization for faces

Face Processing

Autistic Development

Perceptual/Cognitive Hypothesis

  • Perceptual binding (extracting), general deficit (FG), and/or dysfunction of a neural mechanism

Social Motivation Hypothesis (SMH)

  • Primary and secondary deficits (all behavioural and physiological deficits are the result of a deficit in social motivation)
social rewards
Social Rewards

“Social motivation impairments are related to difficulties in forming

representations of the reward value of social stimuli” (Dawson, 2005)

  • Dopamine pathway is activated by social rewards

Reward value  Motivation 

Attention to faces (exposure+) 

Specialization

implications for eibi
Implications for EIBI
  • Make social interaction more rewarding and meaningful
  • Interventions using ABA and EIBI reward using conditioned reinforcement
criticism of eibi
Criticism of EIBI
  • Methodological problems in research
  • Which children are good candidates?
  • Ethical concerns
  • Financial matters
future research
Future Research
  • Using MRI without sedation to assess brain development in high-risk infant siblings (Zwaigenbaum et al., 2005)
  • Behavioural enrichment and behavioural motivation to study brain plasticity (Kilgard)
  • EIBI to reach normal brain functioning in terms of neural speed and cortical specialization (Dawson et al., 2005)
