2. Psychology’s Roots Prescientific Psychology IIs the mind connected to the body or distinct? AAre ideas inborn or is the mind a blank slate filled by experience?

3.  Prescientific Psychology  ________________  knowledge comes from experience via the senses  science flourishes through observation and experiment

4. Psychology’s Roots  _______________ opened the first psychology laboratory at the University of Leipzig (c. 1879).  Studied reaction time

5. Psychology’s Trends  Prescientific Psychology  Scientific Psychology (Wundt)  Psychodynamic Psychology (Freud)  Behavioral Psychology (Watson)  Cognitive Psychology (Beck & Ellis)  Biological Psychology

6. Psychology’s Roots  Definition of Psychology  The ___________ study of behavior (what we do) and mental processes (sensations, perceptions, dreams, thoughts, beliefs, and feelings)  Behaviors-objective and observable  Mental Processes-subjective and unobservable

7. Contemporary Psychology  Are we born as blank slates?  __________________ Controversy  the longstanding controversy over the relative contributions that genes and experience make to development of psychological traits and behaviors  Evidence suggests complex interaction of both genetic and environmental forces

9.  Psychology’s Subfields  Biological Psychology  Exploring the function of the brain and its effects on behavior  _____________ Psychology  Study of changes that occur over the life span  Cognitive Psychology  Study of how we perceive, think, and solve problems  Social Psychology  Study of how we view and affect one another  Personality Psychology  Investigating our inner traits  Clinical Psychology  _____________________________________

10. Why Study Psychology?  Psychologists, like all scientists, use the scientific method to construct theories that organize observations and imply testable hypotheses  The study of psychology helps us organize and understand ourselves and our relationships with the world around us

11. The Scientific Attitude  _________________  thinking that does not blindly accept arguments and conclusions  examines assumptions  discerns hidden values  evaluates evidence  assesses conclusions The Amazing Randi--Skeptic

12. The Scientific Method  Theory  an explanation using an integrated set of principles that organizes and predicts observations  __________________  a testable prediction  often implied by a theory

13. The Scientific Method

14. Description  Psychologists describe behavior using case studies, surveys, and naturalistic observation

15. Description _______________  observation technique in which one person is studied in depth in the hope of revealing universal principals Is language uniquely human?

16. Description  _____________  technique for ascertaining the self- reported attitudes or behaviors of people  usually by questioning a representative, random sample of people

17. Description  Population  all the cases in a group, from which samples may be drawn for a study  _______________________  a sample that fairly represents a population because each member has an equal chance of inclusion

18. Description  ________________  observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation

19. Correlation  ________________  The relationship between the occurrences of two factors  Helps us predict outcomes  Does not reveal causation  _________________  a statistical measure of the extent to which two factors vary together, and thus how well either factor predicts the other Correlation coefficient Indicates direction of relationship (positive or negative) Indicates strength of relationship (0.00 to 1.00) r = +.37

20. Correlation Three Possible Cause-Effect Relationships (1) Low self-esteem Depression (2) Depression Low self-esteem Depression (3) Distressing events or biological predisposition could cause or and

21. Experimentation  Experiment  an investigator manipulates one or more factors (independent variables) to observe their effect on some behavior or mental process (the dependent variable)  by random assignment of participants the experiment controls other relevant factors

22. Experimentation  _____________ Procedure  both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo  commonly used in drug-evaluation studies  _______________  an inert substance or condition that may be administered instead of a presumed active agent, to see if it triggers the effects believed to characterize the active agent

23. Experimentation  Experimental Condition  the condition of an experiment that exposes participants to the treatment, that is, to one version of the independent variable  Control Condition  the condition of an experiment that contrasts with the experimental treatment  serves as a comparison for evaluating the effect of the treatment

24. Experimentation  ___________________  assigning participants to experimental and control conditions by chance  minimizes pre-existing differences between those assigned to the different groups

25. Experimentation  ______________Variable  the experimental factor that is manipulated  the variable whose effect is being studied  _____________Variable  the experimental factor that may change in response to manipulations of the independent variable  in psychology it is usually a behavior or mental process
