PSYCHOLOGY Module 1 The History and Scope of Psychology Psychology’s Roots Prescientific Psychology Is the mind connected to the body or distinct? Are ideas inborn or is the mind a blank slate filled by experience? Prescientific Psychology Rene Descartes (1596-1650) Human Mind held two ideas: Innate (i.e., belief in “God”) Derived (all ideas acquired by experience) John Locke (1632-1704) Empiricism – knowledge acquired by observation All ideas come from experience – no “innate ideas” Mind is a “blank slate” written on by experience Psychology’s Roots Wilhelm Wundt opened the first psychology laboratory at the University of Leipzig (c. 1879) Introspection, psychophysical measurements Structuralism used introspection (looking in) to explore the elemental structure of the human mind Psychology’s Roots Max Wertheimer (18801943) Functionalism, however focused on how behavioral processes function—how they enable organism to adapt, survive, and flourish Gestalt Psychology Early Milestones Stanley Hall – 1st laboratory in U.S. (1883) Herman Ebbinghaus – memory (1885) William James – founded Functionalism (1890) Sigmund Freud – Unconsciousness (1900) American Psychological Association (1892) Ivan Pavlov – Behaviorism (1906) Psychology’s Roots Figure 1- British Psychological Society membership Psychology’s Roots Definition of Psychology The science of behavior (what we do) and mental processes (sensations, perceptions, dreams, thoughts, beliefs, and feelings) How do we know? Validity of knowledge: God is dead. Abortion is wrong. There is a genetic predisposition to schizophrenia. The mind is just like a computer Attitudes affect cancer Pornography is harmful 2 + 2 + 4 Philosophical Developments A Question: How are mind and body related? Dualism - body and soul are separate but interrelated origins in medieval religion soul is seat of intellectual function and will mind is product of the soul mind not subject to scientific inquiry to challenge this was punishable by death Philosophical Developments A Question: How are mind and body related? Rene Descartes (1596-1650) - modified dualism since animals have no soul, much behavior does not require soul the body can therefore control much behavior led him to study reflexes the soul’s main function is thought, a uniquely human attribute Philosophical Developments A Question: How are mind and body related? Materialism: Thomas Hobbes (1588-1679) mind is a product of the brain soul is not involved in human behavior Empiricism: knowledge and intellect are acquired sensory experiences produce elementary ideas elementary ideas become associated into complex thought and ideas Philosophical Developments Another Nativism Question: Empiricism vs. Nativism is the view that elementary ideas are innate If knowledge is innate What is the purpose of education? Can intellect be changed by experience? Are abilities determined by our genes or our experiences? This is known as Nature vs. Nurture appears throughout modern psychology Foundations of Modern Psychology Charles Darwin (1809-1882) Theory of natural selection (1859) physical characteristics evolve through natural selection behavioral patterns also influence selection inborn knowledge and behavioral tendencies with survival value are passed on Human beings are part of nature and can be understood through the methods of science Foundations of Modern Psychology Darwin’s theory encouraged scientific inquiry 19th century developments in physiology demonstrated the approach to use based on scientific methods, controlled laboratory experiments influential beliefs from early physiology reflexology - all human behaviors occur through reflexes localization of function - specific structures of the brain serve specific functions in the control of mental experiences and behavior Other Pioneers Alfred Binet (1857-1911) French intelligence researcher developed first intelligence test Ivan Pavlov (1849-1936) Russian physiologist discovered conditioned reflexes B.F. Skinner (1904-1990) American psychologist at Harvard studied learning and effect of reinforcement behaviorism Contemporary Psychology Psychology’s Big Issues Nature-nurture controversy the relative contribution that genes and experience make to development of psychological traits and behaviors Contemporary Psychology Natural selection principle that those inherited trait variations contributing to survival will most likely be passed on to succeeding generations Andrea Yates Cognitive Perspective Private mental functioning? Biological Basis Brain chemistry depression Social-Cultural Family affair? Extended family Many factors shaping human behavior Contemporary Psychology Psychology’s Perspectives A lot depends on your point of view Contemporary Psychology Contemporary Psychology Psychology’s Subfields Basic Research biological psychologists explore the links between brain and mind developmental psychologists study changing abilities from womb to tomb cognitive psychologists study how we perceive, think, and solve problems Contemporary Psychology Psychology’s Subfields Basic Research Personality psychologists investigate our persistent traits Social psychologists explore how we view and affect one another Contemporary Psychology Psychology’s Subfields Applied Research Industrial/organizational psychologists study and advise on behavior in the workplace Clinical psychologists study, assess, and treat people with psychological disorders Contemporary Psychology Psychiatry A branch of medicine dealing with psychological disorders Practiced by physicians who sometimes use medical (for example, drug) treatments as well as psychotherapy
