Study Notes on Child Development Theories and Perspectives
Developmental Domains
- Physical
- Cognitive
- Social
- Emotional
- Changes in one domain always affect the other domains.
Nature vs. Nurture
- Questions of developmental differences:
- Why do some babies walk at 9 months, while others don’t until 18 months?
- Why do some children learn to read at 4 years, while others struggle at 6 or 7?
- Why are some natural leaders while others are not?
- Factors influencing aggression or gentleness in children.
- Discussion of the extent to which these traits are due to:
- Nature (genetics)
- Nurture (environmental influences)
Voting Exercise
- Participants asked to vote on traits regarding their nature vs. nurture basis:
- Left-handedness:
- Genetic influence: 24% hereditary.
- Often perceived as neither learned nor fully genetic, as slight hereditary aspects exist.
- Musical ability:
- Often viewed as more nurture, but studies show a 42% genetic influence.
- Sensitive hearing and some may possess 'perfect pitch' as genetic traits.
- Prejudice:
- Surprising finding that babies are born with prejudices, as a survival instinct to favor the familiar.
- Mental illness:
- Schizophrenia: 60% genetic;
- Depression: 35% genetic, with environmental triggers contributing significantly.
- IQ Score:
- Estimated to be 70-80% genetic, influenced by environment (parenting style, educational resources).
Theoretical Perspectives in Development
- Five major approaches to development to be studied:
- Biological Perspective
- Psychodynamic Approach
- Learning Theories
- Cognitive Developmental Theories
- Contextual Theories
Focus on Biological Perspective
- Understood through Maturation Theory:
- Development is biologically predetermined based on genetic makeup.
- Maturationists assert minimal environmental influence, focusing on genetically determined growth stages.
- Stages include key developmental milestones (walking, reading).
Arnold Gesell: Key Theorist
- Proposed that driving force behind all human development is biological readiness.
- Emphasized fixed sequences of developmental milestones based off genetic blueprints.
- Mention of studies using twins to understand genetic factors in development.
Importance of Milestones
- Defined measures of what to expect at different developmental stages, shaping educational practices.
- Recognizes that some children may develop abilities outside the average range of typical milestones.
Key Research Findings
- Identical twin studies show strong correlations in traits (similar interests, habits), supporting genetic influence in behavior and intelligence despite environmental differences.
Implications of Theories for Educators
- Understanding of developmental expectations can guide teaching practices:
- Five key perspectives guide responses to students’ development related issues.
- Addressing varying levels of understanding and skills in the classroom.
Critical Periods
- Concept of critical periods reflects importance of timing in learning:
- Children need certain experiences within specific time frames for optimal skill acquisition (e.g., language development).
Application of Theories to Specific Cases
Case Study: Adam’s Behavior
- Factors affecting behavioral output in Adam include:
- Home life conditions, potential bullying, emotional support deficiencies.
- Discussion of potential developmental delays and responses to traumatic experiences.
The Role of Educators
- Educators should address underlying issues rather than simply labeling behaviors.
- Strategies include providing emotional support, adjusting curriculum based on varying developmental needs.
Conclusion
- It is necessary to recognize the interplay between genetics and environment in child development.
- Theories guide practical approaches but also continue to evolve based on ongoing research.
