Behavioral Sciences: Psychology, Sociology, and Anthropology
Behavioral Sciences combines introductory psychology, sociology, and anthropology: research methods, learning and development, social structure and culture, and the comparative study of human societies. Questions reward knowing which theory or method fits a described situation.
Core rules and concepts
- Research methods: experiments establish causation through random assignment and manipulation of an independent variable; correlational and observational studies describe relationships without proving cause. Correlation coefficients reveal strength and direction, not cause.
- Learning: classical conditioning pairs a neutral stimulus with an unconditioned one (Pavlov); operant conditioning shapes behavior through reinforcement and punishment (Skinner). Reinforcement increases behavior, punishment decreases it; positive means adding a stimulus, negative means removing one.
- Development: Piaget's stages run sensorimotor, preoperational, concrete operational, formal operational; conservation appears at the concrete operational stage. Erikson framed development as psychosocial crises across the lifespan.
- Memory: encoding, storage, retrieval; sensory, short-term, and long-term stores.
- Sociology: functionalism (parts serve system needs), conflict theory (power and inequality), symbolic interactionism (meaning created in everyday interaction); socialization, stratification, deviance, and social institutions.
- Anthropology: culture, ethnocentrism versus cultural relativism, participant observation, kinship and subsistence patterns.
Worked example
A student with test anxiety earns praise from a teacher and studies more in later weeks. Reasoning: the praise follows the behavior and increases its frequency, so this is operant conditioning - positive reinforcement. Anxiety itself is better explained by classical conditioning, in which a neutral cue (the testing room) became associated with an unpleasant response. Naming the right paradigm matters more than labeling the emotion.
Traps that cost marks
- Describing a correlation as proof of causation.
- Mixing Piaget's stages, or assigning conservation to the preoperational stage.
- Confusing negative reinforcement (removing something to increase behavior) with punishment.
- Judging another culture by one's own standards while claiming cultural relativism.
