Psychology: the scientific study of behavior and the mind. Behavior: actions and responses that we can directly observe. Mind: internal states and processes, such as thoughts and feelings, that cannot be seen directly and must be inferred from observable, measurable responses. Ex: we cant see if someone actually loves someone else but we can infer based on observations. Clinical psychology: the study and treatment of mental disorders (like therapist) Cognitive psychology: the study of mental processes, especially from a model that views the mind as an information processor they examine: attention, memory, decision making, problem solving. Biopsychology: focuses on the biological underpinnings of behavior. Examine brain processes, genes, and hormones, and their influence on our actions, thoughts, and feelings. Developmental psychology: examines human physical, psychological, and social development across the lifespan. Experimental psychology: focuses on basic processes like learning, senses, and motivational states (ex: hunger/sexual motivation) Uses laboratories often with non human animals. Not the only field that involves experiments.
