  • Prologue: Psychologys RootsPsychological Science Is BornEmpiricismKnowledge comes from experience via the sensesScience flourishes through observation and experiment

  • Wilhelm Wundt

  • Psychological Science is BornFunctionalismInfluenced by Darwin, William James established the school of functionalism, which opposed structuralism. James (1842-1910)Mary Calkins

  • Prologue: Psychologys RootsFunctionalism focused on how behavioral processes function- how they enable organism to adapt, survive, and flourish

  • William James

  • Psychological Science is BornThe Unconscious MindSigmund Freud and his followers emphasized the importance of the unconscious mind and its effects on human behavior.Freud (1856-1939)

  • Psychologys Three Main Levels of Analysis

  • Prologue: Contemporary PsychologyPsychologys Big IssuesStability vs. Change Do our individual traits persist as we age?Do we become older versions of ourselves?

  • Prologue: Contemporary PsychologyRationality vs. IrrationalityRationality reasonableness, good sense of equity and proportionIrrationality not reasonable in thinking or behaving, distorted perception of reality

  • Philosophical Developments Another Question: Nature vs. Nurturethe relative contribution that genes and experience make to development of psychological traits and behaviorsAre abilities determined by our genes or our experiences?What are the interactions between genetics and environment?What effect does it have on behavior?BIG

  • Prologue: Contemporary PsychologyJohn Lockeempiricist; believed that knowledge is acquired solely through life experiences. Tabula Rasa: blank tabletClaimed each of us is born a blank slate on which are written the life experiences we acquire through our senses.(Plato believed just the opposite)

  • Prologue: Contemporary PsychologyRene Descartesrationalist; insisted we should doubt everything that is not proved by our own reasoning. True knowledge comes through correct reasoning and it is inborn.

  • Charles Darwin

  • Prologue: Contemporary PsychologyNatural selectionprinciple that those inherited trait variations contributing to survival will most likely be passed on to succeeding generationsCharles Darwin

  • Psychologys Current Perspectives

    PerspectiveFocusSample QuestionsNeuroscienceHow the body and brain enables emotions?How are messages transmitted in the body? How is blood chemistry linked with moods and motives?EvolutionaryHow the natural selection of traits the promotes the perpetuation of ones genes?How does evolution influence behavior tendencies?Behavior geneticsHow much our genes and our environments influence our individual differences?To what extent are psychological traits such as intelligence, personality, sexual orientation, and vulnerability to depression attributable to our genes? To our environment?

  • Psychologys Current Perspectives

    PerspectiveFocusSample QuestionsPsychodynamicHow behavior springs from unconscious drives and conflicts?How can someones personality traits and disorders be explained in terms of sexual and aggressive drives or as disguised effects of unfulfilled wishes and childhood traumas?BehavioralHow we learn observable responses?How do we learn to fear particular objects or situations? What is the most effective way to alter our behavior, say to lose weight or quit smoking?

  • Psychologys Current Perspectives

    PerspectiveFocusSample QuestionsCognitiveHow we encode, process, store and retrieve information?How do we use information in remembering? Reasoning? Problem solving?Social-culturalHow behavior and thinking vary across situations and cultures?How are we as Africans, Asians, Australians or North Americans alike as members of human family? As products of different environmental contexts, how do we differ?

  • Cognitive PerspectiveHow is knowledge acquired, organized, remembered, and used to guide behavior?Influences includePiaget studied intellectual developmentChomsky studied languageCybernetics science of information processing

  • Humanistic PerspectiveDeveloped by Abraham Maslow & Carl Rogersbehavior reflects innate actualization focus on conscious forces and self perceptionmore positive view of basic forces than Freuds
