The document discusses several types of theories in social sciences, including developmental theories, grand theories, behavioral theories, cognitive theories, mini-theories, emergent theories, and humanistic theories. Developmental theories provide frameworks for understanding human growth and learning. Grand theories propose comprehensive ideas from major thinkers to explain human behavior but are often considered outdated. Behavioral theories are based on conditioning and dominated psychology in the early 20th century. Cognitive theories focus on internal mental processes. Mini and emergent theories describe narrow behaviors or combine ideas from various disciplines, respectively. Humanistic theories emphasized the inherent goodness of humans.
