Human Growth and Development Flashcards
Foundational Perspectives on Human Growth and Development
- Satchel Paige (Baseball Legend): Posed the classic question, "How old would you be if you didn't know how old you were?"
- Wayne W. Dyer (Counselor and Self-Help Advocate): Noted that, "It's never too late to have a happy childhood."
Psychosexual vs. Psychosocial Developmental Theories
- Freud's Psychosexual Theory:
- Developed by Sigmund Freud, the creator of psychodynamic theory.
- Consists of five stages: oral, anal, phallic, latency, and genital.
- Focuses heavily on instinctual drives and sexuality.
- The final stage, the genital stage, begins at age 12\,years and is theoretically said to continue throughout an individual's lifespan.
- A common criticism from scholars is that Freudian theory does not genuinely cover the full lifespan, as it is improbable that a crisis originating at age 12\,years remains the single central developmental issue until senility.
- Asserts that the ego is dependent on the id.
- Erikson's Psychosocial Theory:
- Created by Erik Erikson, a psychoanalyst, disciple of Freud, and leading ego psychologist.
- Consists of eight stages, with each stage representing a psychosocial crisis or turning point (e.g., trust versus mistrust, integrity versus despair).
- Focuses primarily on social relationships rather than psychosexual drives.
- Widely recognized as covering the entire lifespan because the final eighth stage does not begin until age 60\,years.
- Other Key Theoretical Figures:
- A. A. Brill: An analytic theorist whose work is primarily discussed within career development theory.
- Milton H. Erickson: Distinguished from Erik Erikson by the spelling of his surname with a "c"; widely associated with brief psychotherapy and innovative techniques in hypnosis.
- Jay Haley, Arnold Lazarus, William Perry, and Robert Kegan: Prominent developmental, counseling, and psychotherapeutic theorists.
Structural Components of Personality: Id, Ego, and Superego
- Psychodynamic Core Assumption:
- Psychodynamic theories prioritize unconscious processes over cognitive factors when counseling clients.
- The Id:
- Known as the pleasure principle and serves as the seat of sex and aggression.
- Houses animalistic instincts and is chaotic, non-rational, non-logical, and completely void of time orientation.
- Concerned exclusively with bodily demands rather than the external world.
- Exerts continuous pressure on the ego to succumb to basic pleasure drives.
- The Ego:
- Known as the reality principle.
- Operates on logic, rationality, and the powers of reasoning and control to keep instinctual impulses in check.
- Ego psychologists accent the power of ego control and logical reasoning, contrasting with strict Freudians who emphasize the dominance of the id.
- The Superego:
- Represents the moralistic and idealistic portion of the personality structure.
- Behaviorist Critique of Mental Constructs:
- Behaviorists and radical behaviorists reject concepts such as the id, ego, superego, "the mind," and consciousness.
- Rooted in the ontological position that if a psychological construct cannot be physically measured, it does not exist.
Research Paradigms: Idiographic vs. Nomothetic Approaches
- Idiographic Approach:
- Focuses on studying individual subjects in depth rather than aggregating data across groups of people.
- Exemplified by the developmental theories of Sigmund Freud and Jean Piaget.
- Nomothetic Approach:
- Focuses on studying large numbers of subjects to formulate general laws and population-level principles.
- Exemplified by behaviorist research and diagnostic classification systems like the Diagnostic and Statistical Manual of Mental Disorders (DSM).
Jean Piaget's Cognitive Development Theory
- Theoretical Foundations:
- Jean Piaget is the leading figure in child cognitive development.
- Epigenesis: The foundational notion that successful completion and mastery of a preceding stage is an absolute prerequisite for subsequent developmental stages to occur.
- Cultural Invariance: Piaget asserted that the sequential order of stages remains invariant across all cultures, though the precise age at which a child enters a given stage may vary.
- Research Methodology & Critiques:
- Piaget was trained as a biologist before working with Alfred Binet in France (who created the first intelligence test).
- Utilized informal observational research methods, including clinical interviews and structured games.
- Behavioral scientists criticize his findings because his empirical observations were primarily conducted on his own three children: Lucienne, Laurent, and Jaqueline.
- The Four Stages of Cognitive Development (Sequential Order):
- Sensorimotor Stage: Stage 1; emphasizes sensory experience and motoric skills.
- Preoperations Stage: Stage 2; contains the prefix "pre," indicating it must precede concrete operations.
- Concrete Operations Stage: Stage 3; typically occurs during ages 7–11\,years.
- Formal Operations Stage: Stage 4; characterized by abstract operational thought, reflecting the tendency for individuals to become more formal as they age.
- Key Concepts Mastered in Concrete Operations:
- Conservation: The principle that a substance's weight, mass, and volume remain completely unchanged even if its physical shape or container changes.
- Example: A child who observes water poured from a tall, skinny pitcher into a small, squatty pitcher and claims the small pitcher has less water has not yet mastered conservation.
- Reversibility: The cognitive capacity to mentally reverse physical processes or transformations.
- Mental Counting: The ability to count mentally without needing physical objects to perform one-to-one matching.
Specialized Psychological and Research Terminology
- Psychometrics:
- Refers to the field of psychological measurement, mental testing, and quantitative assessment.
- Psychodiagnostics:
- Pertains to assessing personality through interpreting behavior or utilizing standardized measurement tools.
- Allows clinicians to categorize clients into diagnostic categories (e.g., using the DSM, which outlines symptom criteria for mental disorders).
- Psychopharmacology:
- The study of the explicit effects that medications and pharmaceutical drugs exert on human psychological and behavioral functions.
- Inferential Statistics and Hypotheses Testing:
- Parametric t\text{-test}: A formal parametric statistical test used in experiments to evaluate whether there is a statistically significant difference between the means of two groups.
- Formatting and Naming: Symbolized with a lowercase t (t\text{-test}); also referred to in literature as Student's $$t$.
- Assumptions: Requires that the data distributions within the groups being evaluated are normally distributed.
- Type I (Alpha) Errors: Pertains to statistical hypothesis testing where a true null hypothesis is incorrectly rejected; Piaget's informal research methodology did not rely on standard statistical testing impacted by Type I errors.
