Introduction to Human Development Theories and Research Methods

Course Expectations and Administrative Procedures

• Weekly Assignments: The academic schedule for week one is characterized as light, focusing primarily on completion of Learning Curve 1a and Learning Curve 1b.
• Platform Access: Learning curve assignments are accessible through the Achieve system. While students are permitted to work ahead if they choose, there is no requirement to do so.
• Deadlines and Schedules:
  • Learning Curves: Typically due on Sundays.
  • Discussions: Initial posts are generally required by Thursday, with response posts due by Sunday.
  • General Assignments: Most coursework must be submitted by Sunday at $11:59\,PM$.
• Attendance Policy: Attendance is recorded via a digital roster. Students must locate their name in the drop-down menu and change the status from "none" to "p" for present.

Nature versus Nurture and Epigenetics

• Fundamental Concepts: Human development and how individuals "show up" in the world is determined by a combination of nature (genetics) and nurture (environment).
• Genetic Tendencies: Specific traits and tendencies are frequently repeated across generations within families. These can be categorized as:
  • Physiological: Physical attributes or capabilities, such as being ambidextrous or having specific artistic talents.
  • Cognitive: Thinking patterns and intellectual interests.
  • Behavioral: Temperamental traits like introversion versus extroversion.
• Epigenetics: This field of research explores how early life experiences can alter the outer cover of DNA, leading to lifelong changes in health and behavior.

Erik Erikson: Psychosocial Theory of Development

• Theoretical Framework: Erikson, a German-American psychologist influenced by Sigmund and Anna Freud, developed the psychosocial theory. Unlike Freud, who focused on sexuality, Erikson argued that human motivations are centered on the independent self and relationships with others.
• The Eight Stages of Development: Erikson identified unique challenges or "identity crises" faced at each stage of life from birth to death.
  • Stage 1: Basic Trust versus Mistrust (Infancy): Infants ask if the world is safe. Success leads to the ability to trust others in the future; failure leads to fear and doubt. The mother/caregiver is the key influence.
  • Stage 2: Autonomy versus Shame and Doubt (Early Childhood): Children ask, "Is it okay to be me?" Exploration leads to self-confidence; being held back leads to shame. Both parents are the primary influence.
  • Stage 3: Initiative versus Guilt (Preschool): Children try new things and learn basic principles (e.g., how objects roll). If encouraged, they follow interests; if discouraged, they develop guilt. The entire family is the key influence.
  • Stage 4: Industry versus Inferiority (School Age): Children realize they are different from others and ask if they can "make it" in the world. Recognition leads to being industrious (hard-working); negative feedback leads to inferiority. Neighbors and schools are the primary influences.
  • Stage 5: Identity versus Role Confusion (Adolescence): Adolescents navigate social roles (friend, student, citizen). Exploration leads to a sense of identity; forced conformity leads to confusion. Peers and role models are the key influences.
  • Stage 6: Intimacy versus Isolation (Young Adulthood): Individuals seek long-term commitments and ask if they can love. Success leads to confidence; failure leads to isolation. Partners and friends are the primary influences.
  • Stage 7: Generativity versus Stagnation (Middle Adulthood): Adults in their $40s$ aim to contribute to society and lead the next generation. Failure to resolve earlier conflicts leads to pessimism and stagnation. Household and work contacts are the primary influences.
  • Stage 8: Ego Integrity versus Despair (Late Adulthood): Older adults look back at life. Contentment leads to integrity; regret leads to bitterness and despair. Comparison with all of mankind is the final developmental task.

Jean Piaget: Cognitive Developmental Theory

• Core Principle: From infancy to adolescence, children progress through four qualitatively different stages of intellectual growth.
• Assimilation: This is the process of bringing new information into a collective, existing framework of knowledge.
• The Four Stages:
  1. Sensory Motor ($0$ to $2$ years): Development of gross motor skills and the ability to connect language to physical items.
  2. Preoperations: Perceptions are captured by immediate appearances. Children at this stage may struggle with conservation (e.g., failing to realize the amount of liquid remains the same when poured into a different-sized cup).
  3. Concrete Operations: Children develop a realistic and logical understanding of the world.
  4. Formal Operations: The development of abstract thinking and advanced reasoning.

Bronfenbrenner’s Ecological Systems

• Systemic Influence: Human development is shaped by overlapping external systems. These include:
  • Personal systems: Family, peers, and religious groups.
  • Social/Community systems: School systems, community, and medical institutions.
  • Macro systems: Mass media, economic patterns, and major social events.
• Defining Social Events: Major events that define generations include $9/11$, the $COVID-19$ pandemic, the advent of the Internet, the rise of Social Media, and the emergence of AI (Artificial Intelligence).

Research Methods in Human Development

• Correlation versus Causality:
  • Correlation: A research strategy relating two or more variables where the presence of variable $A$ makes variable $B$ more likely to occur.
  • Causality: A definitive relationship where if event $A$ happens, then event $B$ must occur ($A \rightarrow B$).
• Representative Sample: A research group that accurately reflects the characteristics of the overall population. For example, a sample of college students in Colorado is not a full representation of the entire United States population.
• Naturalistic Observation: A strategy involving the direct watching and coding of behaviors as they occur in a natural setting.
• Measurement Strategies:
  • Self-Reporting: Techniques where participants report on feelings or activities via questionnaires (e.g., PHQ/Patient Health Questionnaire for depression or GAD for anxiety). These are subjective and depend on the individual's self-awareness.
  • Observer Evaluation: A knowledgeable person (parent, teacher, clinician) uses scales to evaluate a participant. This is intended to be objective but can contain bias.
• Study Designs:
  • Cross-Sectional Study: Compares different age groups at a single point in time to measure group differences.
  • Longitudinal Study: Tests the same group (a cohort) repeatedly over many years. Challenges include participant attrition (people leaving the study or passing away). Examples include twin studies and MAPS (Multidisciplinary Association for Psychedelic Studies) research in Colorado.
• Research Ethics: Researchers should aim to rule out facts and alternative hypotheses rather than simply seeking to confirm their own beliefs.
• Data Types:
  • Quantitative Research: Data-driven research expressed through numerical scales and statistics (e.g., "$80\%$ of participants responded in a specific way").
  • Qualitative Research: Focuses on personal interviews and descriptions of experiences and feelings rather than numerical data.

Cultural Variations and Community Practices

• Culture as a Constant: All children are members of a cultural community. Culture is often invisible to those immersed in it, described by the metaphor that "a fish doesn't know about water."
• San Pedro, Guatemala Study: In Mayan communities, children are integrated into adult settings from an early age. They are welcomed into adult work environments and are expected to participate.
• Middle-Class Western Comparison: In middle-class European American upbringing, children are often segregated from adult settings. They rarely see their parents at work and have more restrictions on their movement and observations within the home.

Questions & Discussion

• Question (Audience): Regarding trust versus mistrust, does that stage actually end at age two, or does it continue throughout life?
• Response: The concept of trust vs. mistrust can be seen as an ongoing process. If someone important proves untrustworthy later in life, an individual may become less trusting overall.
• Question (Audience): Are self-reports and observer evaluations dependable if they are based on personal perspectives?
• Response: Self-reporting is subjective. Its reliability depends on the participant's level of self-awareness. Observer evaluation is intended to be objective and data-driven but is still subject to the observer's biases.
• Class Activity (Generational Comparison):
  • Group 1 ($1990\text{s}$): Identified music like Eminem and Snoop Dogg; movies like The Goonies and Little Rascals; and the "What's up?" Budweiser commercial slang.
  • Group 2 ($2005-2007$): Identified music like Eminem; clothes described as "skater/Tony Hawk" style; and movies like The Hobbit and the Star Wars prequels.
  • Group 3 ($2007-2010$): Identified music like Drake and Ella Langley; clothes like Birks with socks and athletic wear; and movies like the Avengers series and Grey’s Anatomy.
  • Slang Trends: Common terms identified across younger groups include "Slay," "Lit," "Fire," "Bruh," "Chat," and "Twin."
  • Observation: Many cultural elements (e.g., Taylor Swift, The Princess and the Frog) have persisted across these demographic shifts, showing a transition from Millennial to Gen Z tastes.
