© 2012 John Wiley & Sons, Inc. All rights reserved. The FOUR Goals of Psychology Describe What is the nature of the behavior or mental process? “Boys are more aggressive than girls.” Explain Why does this behavior or mental process occur? “Research indicates that there are numerous interacting causes or explanations for aggression, including culture, learning, genes, brain damage, and high levels of testosterone.” Predict When will this behavior or mental process occur? “Knowing that alcohol leads to increased aggression, we can predict that more fights will erupt in places where alcohol is consumed than in those where alcohol isn’t consumed.” Change How can we CHANGE this behavior or mental process? Psychologists help people improve their work environment, stop addictive behaviors, become less depressed, improve their family relationships

Which Goal of Psychology is Represented by Each Example? Researchers have recently identified a gene that predisposes certain individuals to become obese because their satiety mechanism doesn‘t “turn on.” Some developmental psychologists believe that many more playground accidents will occur this year among young children who watch violent cartoons. Comprehensive sex education should be required in all high schools because studies demonstrate that such education has reduced the teenage pregnancy rate. Surveys show that women who graduate from college earn as much money per year as men who graduate from high school. © 2012 John Wiley & Sons, Inc. All rights reserved.

Psychology’s Past STRUCTURALISM Sought to identify the structure of mental life by identifying “elements” of conscious experience combined to form the “compounds” of the mind, via introspection. FUNCTIONALISM Sought to identify the functions of experience, i.e., why do we experience anger and what value does it have? © 2012 John Wiley & Sons, Inc. All rights reserved. A Brief History PSYCHOANALYSIS Focused on unconscious processes and unresolved conflicts that influence current behavior.

Six Steps of the Scientific Method Cycle © 2012 John Wiley & Sons, Inc. All rights reserved.

Important Terms! Hypothesis Specific, testable prediction about how one factor, or variable, is related to another Operational Definition Precise description of how the variables in a study will be observed and measured (for example, drug abuse might be operationally defined as “the number of missed work days due to excessive use of an addictive substance”) Statistical Significance Statistical statement of how likely it is that a study’s result occurred merely by chance © 2012 John Wiley & Sons, Inc. All rights reserved.

Three Areas of Ethical Concern Informed consent Voluntary participation Restricted use of deception and debriefing Confidentiality Alternative activities © 2012 John Wiley & Sons, Inc. All rights reserved.

Three Areas of Ethical Concern In all institutions where nonhuman animal research is conducted, animal care committees are established to ensure proper treatment of research animals, to review projects, and to set guidelines that are in accordance with the APA standards. © 2012 John Wiley & Sons, Inc. All rights reserved.

Three Areas of Ethical Concern Personal information and therapy records must be kept confidential, with records being available only with the client’s permission. The public’s right to safety ethically outweighs the client’s right to privacy. Therapists are legally required to break confidentiality if a client threatens violence to him or herself or to others. Breaking of confidentiality also applies if a client is suspected of abusing a child or an elderly person. © 2012 John Wiley & Sons, Inc. All rights reserved.

Experimental Research: A Search for Cause and Effect © 2012 John Wiley & Sons, Inc. All rights reserved.

RESEARCH METHODS: EXPERIMENTAL Experimental research: carefully controlled scientific procedure that manipulates variables to determine cause and effect © 2012 John Wiley & Sons, Inc. All rights reserved.

Research Methods: Experimental Key features of an experiment: Independent variable versus dependent variable Experimental group versus control group Random assignment Controlling confounding variables © 2012 John Wiley & Sons, Inc. All rights reserved.

Labeling Variables and Groups Label the IV, DV, Control Group and Experimental Group for each scenario A researcher is interested in how the activity level of four-year-olds is affected by viewing a 30-minute video of Calliou or a 30-minute video of X-Men. A therapist wants to test a new drug designed to increase the ability of teenagers with ADHD to take accurate notes in class. A biopsychologist wants to know if exposure to testosterone in adult female rats increases their aggressive behavior. A social psychologist is interested in whether or not there is a gender difference in how much money men and women will say they should be paid for the same task. An industrial psychologist believes that cooling the room temperature may have an impact on productivity levels in the assembly line. © 2012 John Wiley & Sons, Inc. All rights reserved.

Experimental Methods: Potential Researcher Problems Experimenter Bias When the researcher influences the results in the expected direction Single-Blind Study Only the researcher, and not the participants, knows who is in either the experimental or control group Double-Blind Study Both the researcher and the participants are unaware (blind) of who is in experimental or control group Ethnocentrism Believing one’s culture is typical of all cultures, is central and “correct,” and judging others by this standard. © 2012 John Wiley & Sons, Inc. All rights reserved.

Experimental Methods: Potential Participant Problems Placebo Inactive substance used as a control Sample Bias Occurs when research participants are not representative of the larger population Random Assignment Using chance methods to assign participants to experimental or control conditions Participant Bias Occurs when experimental conditions influence the participant’s behavior © 2012 John Wiley & Sons, Inc.

Design a Scientific Experiment A motivational speaker claimed that wearing red on the day of an exam "energizes" the brain and improves performance. Your psychology professor doubts this is true. Design an experiment that would see if the speaker was correct. An English professor believes that students who have the opportunity to write their in- class essays on computers will produce better essays than those who write their essays by hand. Design a study that tests the professor’s belief. An exercise physiologist counsels his clients to exercise in the morning rather than at night to facilitate weight loss. Your task is to design an experiment to see if this is the correct advice. Many parents assert that children "amp out" or go "off the wall" after they eat sugar. Design a study to determine whether or not this assertion is true. Questions to Answer Do you need to define any terms for your experiment? Do so. What is your independent variable? What is your dependent variable? How will you select and assign your subjects to a group? What treatment will the experimental group be given? What treatment will the control group be given? What controls will you use in your experiment? Be sure to avoid experimenter and participant biases. Is there anything you think you should control but aren't sure how? © 2012 John Wiley & Sons, Inc.

DESCRIPTIVE RESEARCH: NATURALISTIC OBSERVATION, SURVEYS AND CASE STUDIES Descriptive research: research methods that observe and record behavior and mental processes without producing causal explanations © 2023 John Wiley & Sons, Inc. All rights reserved.

Descriptive Research NATURALISTIC OBSERVATION Observation and recording behavior and mental processes in the participant’s natural state or habitat. SURVEY Research technique that questions a large sample of people to assess their behaviors and attitudes. © 2012 John Wiley & Sons, Inc. All rights reserved. CASE STUDY In-depth study of a single research participant.

CORRELATIONAL RESEARCH Research method in which variables are observed or measured (but not directly manipulated) to identify relationships between them. © 2012 John Wiley & Sons, Inc. All rights reserved.

Understanding Correlations Strength of Relationship Correlation coefficients are calculated by a formula that produces a number ranging from 1.00 to Both and are the strongest possible relationship. As the number decreases and gets closer to 0.00, the relationship weakens. Direction of Relationship Positive Correlation is one in which the two variables move (or vary) in the same direction—the two factors increase or decrease together. Negative Correlation is one in which two factors vary in opposite directions © 2012 John Wiley & Sons, Inc. All rights reserved.

Distinguishing Between Experimental & Correlational Research For each of the following five reports: 1) Decide whether the study is CORRELATIONAL or EXPERIMENTAL. 2) If the study is correlational, briefly describe how the variables are related and whether the correlation is positive or negative. List possible third variables or confound causes that might also be influencing the results. 3) If the study is experimental, briefly describe how Variable A is causing Variable B. Study I A Dartmouth study found that overweight young women (23 years old) earned 6.4% less than non-overweight peers. Additionally, it found that the earnings of young men rose 2% for each 4-inch increase in height. Study II An Australian study reported that MSG does not cause people to be sick, as was previously reported. The researcher told subjects that he was studying ingredients in a new soft drink, and fed them either MSG or a placebo in the drink. The same number and type of symptoms were reported in both the MSG and the placebo groups. Study III USA Today reported that the stock market ends the year with a gain if the Super Bowl is won by one of the original NFL members ̶–all the NFC and three AFC teams (the Indianapolis Colt, Pittsburgh Steelers and Cleveland Browns). Study IV A psychiatrist from England found that wealthy women aged 35 to 59 had more frequent sex, more orgasms and reported enjoying sex more than women from poorer households. Study V Despite popular belief, men are just as likely to "help" as women. In fact, one study indicated they were more likely to engage in helping behavior as women. When confederate men and women were staged in a parking lot apparently having locked their keys in their car, 80% of the individuals who came over to see if they needed help were men! The staging was done such that equal numbers of men and women would pass by. © 2012 John Wiley & Sons, Inc. All rights reserved.
