DEVELOPMENTAL PSYCHOLOGY FOCUS: FULL LIFESPAN WHAT: CHILDHOOD ADOLESCENCE ADULTHOOD ELDERLY NONHUMANS TASK: 1. CAN WE PREDICT LATER LIFE FROM EVENTS EARLIER IN LIFE? 2. ARE EARLIER EVENTS “CAUSAL”? 3. IF SO­­CAN WE CHANGE THE DEVELOPMENTAL OUTCOME? 3 SOME EXAMPLES DOES VIOLENCE ON TV HAVE THE SAME EFFECT ON CHILDREN OF DIFFERENT AGES?

NonHuman Primate Research Monkeys Reared Only In Diffuse Light Result = Retarded Development Next Enriched Environment Result = 1. Resiliency 2. Required Less Experience To Catch Up What Would Piaget Say? 28 Canine Research Dogs Reared Without Human Contact & Confined Result “Stupid Dogs” Not Found To Be Resilient 29 An Overall Conclusion Generally Early Deprivation Results in Animals/Humans That Do Not Learn as Quickly Decreased Cortical Thickness Decreased Brain Weight Decreased Neuronal Associations 30 Environmental Enrichment The 1960s, DDT, & Sterile Environments Researchers Discover The Incubator Effect Retarded Development Attempted to Enrich the Incubator Added Sounds, Movement, Color, etc. Results Accelerated Rate of Development A Nation Focused on Enrichment 31 A Caution From Piaget? Isolation or Deprivation = Aversive Child Will Seek Stimulation Stimulation Must Be Appropriate to the Developmental Level The Biological Platform 32 One More Orphanage Experiment Surrogate Mother Group Baseline +32 IQ Points Control Group -21 T I M E 33 Development of Social Attachment Harry Harlow Past President of A.P.A. “Mother Love” What is the Critical Ingredient?
