Notes on Theoretical Perspectives in Human Development
Psychoanalytic Theories
- Core assumption: development involves moving through stages where individuals confront conflicts between biological drives and social expectations; how conflicts are resolved influences psychological adjustment (e.g., learning, social relationships, anxiety coping).
- Freud (psychosexual theory)
- Father of psychoanalytic perspective.
- Development proceeds through psychosexual stages in which unconscious drives focus on different parts of the body.
- Key contribution: emphasis on early family experiences and how an individual's life history shapes development.
- Current view: largely unpopular today; critiques focus on overemphasis of sexuality; nonetheless, underscored that life history events shape development.
- Erikson (PsychoSocial Theory of Development)
- Expanded Freud to cover the entire lifespan; added adult stages.
- Emphasizes that normal development must be understood in relation to cultural context.
- Stages involve conflicts between biological drives and social expectations at each stage.
- Strengths: highlights lifelong development and the influence of life history; spurred research on attachment, morality, and child-rearing practices.
- Limitations: stages can be vague; empirical testing is challenging.
Behaviorist and Social Learning Theories
- Core idea: behavior is shaped by the environment; psychology should focus on observable stimuli and responses; internal mental states are not the primary focus.
- John Watson (Behaviorism)
- Sought an objective science of behavior anchored in observable events; avoided speculation about unobservable mental states.
- Classical Conditioning (Pavlov-inspired; applied by Watson to development)
- Learning through association: a neutral stimulus becomes capable of eliciting a response after being paired with a stimulus that already elicits that response.
- Example in the lecture: ringing a bell paired with food leads to salivation; later, bell alone elicits salivation.
- Definition: a form of learning in which environmental stimuli come to elicit physiological responses through association.
- Operant Conditioning (B.F. Skinner)
- Behavior probability changes based on consequences.
- Reinforcement: a behavior followed by a rewarding/pleasant outcome increases likelihood of that behavior.
- Punishment: a behavior followed by an aversive/unpleasant outcome decreases likelihood of that behavior.
- Application: explains how skills and habits are learned; individuals actively shape their development through responses to reinforcement and punishment.
- Social Learning Theory / Social Cognitive Theory (Albert Bandura)
- Emphasizes active information processing; thoughts and feelings influence behavior.
- Modeling/observational learning: people learn by observing and imitating others.
- Reciprocal determinism: individuals and environments influence each other.
- Self-efficacy and personal standards: developed through observation and feedback.
- Modern view is often described as Social Cognitive Theory, focusing on thoughts about self and others and self-regulation.
- Contributions and applications
- Behavior modification can treat undesirable behaviors (e.g., poor time management, fears).
- Limitations
- Critics argue this view can offer too narrow an account of environmental influences and may underestimate individuals’ active role in their own development.
Cognitive Theories
- Focus: cognition is central to understanding functioning across the lifespan.
- Piaget's Cognitive Developmental Theory
- People are active explorers driven to learn by interacting with the world and by organizing knowledge into cognitive schemas (concepts and methods for interacting with the world).
- Development progresses through four broad stages:
- Sensorimotor stage: infancy; learning through senses and movements.
- Preoperational stage: early childhood; symbolic but illogical thinking.
- Concrete Operational stage: school-age; more organized and logical reasoning.
- Formal Operational stage: adolescence and beyond; abstract and systematic reasoning.
- Strengths: one of the most widely cited theories; emphasizes active knowledge construction.
- Critiques: may overemphasize cognitive aspects while underemphasizing emotional and social factors.
- Information Processing Theory
- The mind works like a computer; information is encoded, processed, stored, and retrieved.
- Enables precise, testable predictions about behavior.
- Critique: tends to ignore non-linear, imaginative, and creative aspects of cognition.
Contextual Theories
- Core idea: development is shaped by socio-cultural contexts and their interactions with biology and cognition.
- Vygotsky's Sociocultural Theory
- Culture is transmitted through social interactions.
- Cognitive development is a social process; learning occurs via dialogue with more knowledgeable members of society.
- Emphasized the central role of culture and social context in development.
- Bronfenbrenner's Bioecological Systems Theory
- Development results from ongoing interactions within multiple nested contexts and changing systems over time.
- Systems (from inner to outer): micro-system (immediate environment), meso-system (interconnections among micro-systems; transcript uses the term "message system"), exosystem (settings that influence the individual indirectly; transcript uses "access system"), macrosystem (broader cultural context), and chronosystem (time dimension).
- Strength: offers a differentiated, comprehensive account of contextual influences.
- Criticisms: complexity and potential over-explanation; can be difficult to apply succinctly.
- Dynamic Systems Theory
- Development is seen as the integration of multiple domains (maturation and environment) forming a constantly changing system.
- Milestones emerge through goal-directed skill-building; growth is organized around purposeful activities and the interrelation of factors.
Ethology and Evolutionary Developmental Theory
- Ethology
- Scientific study of the evolutionary basis of behavior.
- Proposes that humans display preprogrammed biological behaviors that promote development.
- Focuses on adaptive/survival value of behavior and its evolutionary history.
- Evolutionary Developmental Theory ( Evo-Devo )
- Applies principles of evolution and the interactive influence of genetic and environmental mechanisms to understand lifelong changes.
- Emphasizes genetic factors and their interaction with physical and social environments in shaping development.
