Lifespan Development as a Field of Study

Related Scientific Areas

  • Developments in psychology and disciplines related to human growth.

  • Psychology:

    • Scientific study of the mind and behavior.

    • Behavior: observable actions driven by affect and cognition.

  • Affect and Cognition:

    • Affect: emotional experiences.

    • Cognition: mental processes including memory and language.

  • Historical context of psychology: founded in 1879 by Wilhelm Wundt.

Definitions and Concepts in Development

Lifespan Development

  • Lifespan development from conception to death; includes biological and psychological growth.

  • Concepts:

    • Maturation: biological growth changes (e.g., height, physical traits).

    • Developmental psychologists identify stability patterns over time.

    • Issues of temperament and personality in developmental stability.

Human Development

  • Multidisciplinary approach to understanding developmental processes.

  • Focuses on broad influencing factors across various disciplines such as anthropology and sociology.

The History of Lifespan Development

Early Beginnings

  • Child study movement in the 1890s sparked professional interest in child development.

  • French physician Jean-Marc Gaspard Itard's early observations of human development.

  • Philosophy's early engagement with development stems from ancient Greece and historical figures like Socrates, Plato, and Aristotle.

Core Questions of Lifespan Development

  • Investigate expected changes and timing across the lifespan.

  • Application of developmental knowledge in fields (e.g., healthcare, education, public policy).

  • Public policy influenced by psychological research to improve societal outcomes (e.g., driving regulations for teenagers).

Examining Money and Happiness

  • Relationship between income and subjective happiness:

    • Findings reveal a correlation where beyond $90,000 income, happiness levels off.

  • Contributing factors to happiness include self-esteem and social support.

  • Exploring psychological pro-social elements that promote life satisfaction.

The Psychological Domains of the Developing Individual

Influencing Factors on Development

  • Development influenced by emotional experiences, personality traits, social skills, and biological growth.

  • The interplay of behavioral and cognitive aspects shaped by biological maturation.

  • Overview organized across major functional areas of development.

Intersection of Topics: Eating Disorders Example

  • Developmental aspects include physical, cognitive, emotional, and personality domains.

1.2 Themes of Development

Learning Objectives

  • Explain continuous vs. discontinuous development.

  • Understand the nature vs. nurture debate.

  • Importance of timing in developmental opportunities.

Continuous vs. Discontinuous Development

  • Concepts of stage theories explaining patterns of development:

    • Continuous: gradual growth observable over age.

    • Discontinuous: stages featuring rapid change periods.

Nature vs. Nurture

  • Influence of genetics (nature) vs. environment (nurture) in development.

  • Most characteristics influenced by a combination of both.

  • Heritability estimates measure genetic contribution to a trait.

Critical/Sensitive Periods in Development

  • Critical periods: necessary experiences for development (e.g., language learning).

  • Sensitive periods: advantageous conditions for ideal skill development.

Variability and Diversity

  • Emphasis on individual variation in developmental psychology.

  • Examples of cultural variations in parenting impacting child developments, e.g., motor skills development.

1.3 Major Theories and Theorists

Learning Objectives

  • Describe major theories in lifespan development.

  • Connect theories to life themes.

  • Compare different theoretical perspectives.

Erik Erikson – Psychosocial Theory

  • Eight stages of human development framed around psychosocial crises.

  • Stresses interactive relationship between individual and societal expectations.

Jean Piaget – Cognitive Development

  • Theory focused on cognitive abilities evolving through stages.

  • Stages include sensorimotor, preoperational, concrete operational, and formal operational.

Vygotsky – Social Development Theory

  • Emphasis on social interaction's role in learning and cognitive development.

  • Concepts such as scaffolding and the zone of proximal development.

Behaviorist Theories

  • Foundations laid by figures such as Pavlov and Skinner examining learning processes, including classical and operant conditioning.

1.4 Contexts and Settings of Development

Learning Objectives

  • Explain contextual perspectives in development.

  • Discuss Bronfenbrenner’s ecological model of development.

Bronfenbrenner’s Ecological Systems Model

  • Framework illustrating inter-connectedness of individual development within varied contexts:

    • Microsystem: direct interactions (family, school).

    • Mesosystem: connections between microsystem interactions (e.g., parental involvement in education).

    • Exosystem: broader social settings that indirectly affect the child (e.g., caregiver’s workplace).

    • Macrosystem: overarching cultural beliefs and ideologies.

    • Chronosystem: sociohistorical context impacting development.

Individual Contexts' Influence

  • Example of how individual experience varies through shared cohort effects or sociocultural influences.

  • Research findings differentiated by subgroup context (race, gender, ethnicity).

1.5 Lifespan Development as a Science: Research Methods

Learning Objectives

  • Discuss principles of research methods in developmental psychology.

Research Design Overview

  • Utilize various methods: case studies, naturalistic observation, correlational designs, experimental methods.

    • Each method bears strengths in reliability and weaknesses in validity based on application context.

  • Emphasis on ethical considerations enriching participant treatment and safeguarding in research contexts.

Understanding Validity and Reliability

  • Definitions of validity (accuracy of measure) vs. reliability (consistency in results).

  • Challenges faced when employing correlational research: misinterpreting causal implications.

Method-Specific Insights

  • Discussion of longitudinal, cross-sectional, and cross-sequential designs as methods to track individual development.

  • Illustrations of how practical challenges influence the feasibility of research design.

Ethical Considerations in Research

  • Discuss the role of Institutional Review Boards (IRBs) in safeguarding participant rights.

  • Emphasis on informed consent, participant equity, and balance of risk versus benefit.

Specific Case Studies in Ethical Practices

  • Discuss historical examples including the Tuskegee Study.

Conclusion of Topic

  • Lifespan development integrates multiple psychological research methodologies to provide a comprehensive understanding of human growth and behavior.
