Key Theories in Lifespan Development
PDF resources, like textbooks by Santrock, detail psychodynamic, behavioral, cognitive, and ecological theories, providing frameworks for understanding human growth․
Psychodynamic Theories
Psychodynamic perspectives, frequently explored in PDF-formatted developmental psychology texts, emphasize unconscious processes and early childhood experiences as crucial shapers of personality․
Sigmund Freud’s psychosexual stages – oral, anal, phallic, latency, and genital – propose that unresolved conflicts at each stage influence adult character․
Erik Erikson expanded upon Freud’s work, formulating psychosocial stages spanning the entire lifespan, each presenting a unique developmental crisis to resolve․
These theories, often detailed within comprehensive PDF guides like those by Santrock, highlight the enduring impact of early relationships and internal drives on development, though they’ve faced criticism for lacking empirical support․
Understanding these foundational concepts, readily available in digital formats, provides a historical context for modern developmental thought․
Behavioral and Social Cognitive Theories
Behavioral and Social Cognitive theories, often detailed in accessible PDF resources, propose that development is largely shaped by environmental interactions and observable behaviors․
B․F․ Skinner’s operant conditioning emphasizes how reinforcement and punishment mold behavior throughout life, a concept frequently illustrated in developmental PDFs․
