Human Development – Brain
Cells that fire together, wire together. By the time you reach adolescence you lose 50% of brain cells. Grey matter is cell bodies we only use about 10% of our brains capacity = FALSE, we use all of It. Cortex Frontal Lobe Ability to calm ourselves down and think things through Set goals, think ahead Try to figure out what other people are thinking Making good decisions Damage to frontal lobe Phonies Gage Parietal Lobe Eyes, ears, fingers, tongue go for processing Where you are in space Damage to parietal lobe Inability to sense aspects of the world Damage to Occipital Lobe
Blindsiding Temporal Lobe Auditory Info Encoding of memory Regulation of emotion Damage to temporal lobe Inability to experience fear Brain development Occipital lobe is early bloomer Takes the longest to reach its optimal state Limbic System Theories of Development Perspective Psychodrama- internal thought processes Learning Cognitive developmental- how people think ecological and systems life-span 100 years ago no developmental theories. Children fully developed by adolescence Purpose of theories Ground & guide research How children interact with the world
How we develop across time. Physical and psych How we relate to the environment around us How does change occur? Nature vs. Nurture Bio vs. environment Heredity or Social environment External world + internal world Continuity vs. Discontinuity Is change gradual or abrupt Universal or Context Specific = us Universal development- normative developments that all individuals display. Context- specific development: developmental outcomes that vary from person to person Both Major Developmental Theories 1 . Psychodrama- Psychosocial / Psychoanalytic (Freud / Erikson) 2.
Learning theory- behaviorism (Watson / skinner) social learning (bandeau) 3. Cognitive development- Pigged, info processing theory, Whisky 4. Ecological & systems approach- Frontbencher, competence-environmental press theory 5. Lifespan perspectives- Ballets, selective optimization with compensation, life-course perspective Learning: Behaviorism Experience is all that matters Focus on behavior & its causes Operant Conditioning Social Learning – Bandeau Self efficacy Imitating Social and cognitive component Cognitive Developmental Theory- Pigged Father of developmental psych
Child as a scientist Info processing theory Bigots Theory – calculators intelligence, cultural transmission to ski systems theory Uri Frontbencher Russian dolls Interconnected systems Dynamic view Development is inseparable from environmental context Life Span Perspectives History, context, and timing is crucial Development- what happens before and what comes after Ballets Multidimensionality – growth & decline Plasticity Skills can be learned or improved Historical Context Time and Culture Multiple Causation Biological / psychological / calculators
Malaria Study 26 out of 40 delivered the maximum shocks (65%) Many participants were very agitated, distraught & angry Debriefed at the end of experiment Ethics in Research Most people didn’t know they were being used in studies Measuring Human Behavior and Development *Structured Tasks- People watching ills ecological Reliability: extent to which a measure provides a consistent index of a characteristic Validity: extent to which a measure actually assesses what researches think it does Sequential Design: *Shorter length of time *Different aged children
