Psychology 101 Notes Defining Psychology Scientific study of behavior and mental processes Key terms Science Behavior Mental Processes Psychological Frame of Mind Psychologists approach life questions as scientists Attitudes of scientific approach critical thinking curiosity skepticism objectivity Science of All Human Behavior Not just about psychological disorders diverse field understanding truths of human life in all its dimensions includes people s best and worst experiences Careers in Psychology Clinical 24 Industrial 12 Academic 34 Private Practice 22 Schools 4 Other 4 Structuralism Wilhem Wundt 18321920 German philosopherphysician First psychology laboratory 1879 Identify elements or structures of mental processes introspection Functionalism William James18421910 American psychologist and philosopher Identify purposes or functions of the mind Why is human though adaptive Natural flow of thought or stream of consciousness Evolution amp Natural Selection Charles Darwin18091882 British Naturalist Natural selection is adaptive and functional Nature favors traits that promote reproduction and survival Successful characteristics become dominant Contemporary Approaches Biological Behavioral Psychodynamic Humanistic Cognitive Evolutionary Sociocultural Biological Approach Focus on brain and nervous system Neuroscience Structure function Behavioral Approach Emphasis on observable behavioral responses and their environmental determinants Notable Behaviorists John B Watson BF Skinner Psychodynamic Approach Emphasis on Unconscious Conflict between biological drives and society Childhood early family experiences Founding father Sigmund Freud Humanistic Approach Emphasis on Positive human qualities Capacity for positive growth Freedom to choose any destiny Notable Humanistic Psychologists Carl Rogers Abraham Maslow Cognitive Approach Emphasis on mental processes involved in knowing How we direct attention perceive remember think solve problems Evolutionary Approach Use of evolutionary ideas Adaption Reproduction Natural Selection Sociocultural Approach Examination of ways in which social and cultural environments influence behavior Focus on comparisons of behavior Scientific Method Observation Choose a variable phenomenon studied by scientists anything that can change Develop a theory idea that attempts to explain observations seeks to explain why something happened can be used to make predictions Scientific Method Hypothesis Formulate a hypothesis educated guess derived from theory Scientific Method Research Establish an operational definition objective description of variable how will variable be measured Collect and analyze data number crunching what do data mean Scientific Method Conclusions draw conclusions is theory supported should theory be changed Evaluate conclusions publication and review ongoing research process Types of Psychological Research Descriptive research Finding out about some variable
