Psychology Lecture 1: Introduction to what psychologists study and research methods Instructions and expectations: I will give you lecture outlines for every lecture. On the tables, I will list all of the key terms that will appear within the lecture. It is your job to write down definitions so that you have a complete glossary of terms. The third column is for examples or questions or thoughts you have during the lecture. Term/question Def./answer What is psychology the study of? • Behavior • Involunta ry vs. voluntary • Mental process Examples, extra notes Term/question Def./answer Psychology also asks… • nature • nurture Examples, extra notes Term/question Def./answer What do psychologists do? • intrapersonal • interpersonal Examples, extra notes Research Methods A look at how psychologists conduct research and some classic psychology experiments Jane Elliot’s blue eyes vs. brown eyes experiment 1. Research question: 2. Hypothesis: Blue Eye experiment 3. Procedures Day 1: Day 2 End of day 2: 4. Observations/data Blue Eye experiment 5. Elliot’s conclusions: Blue Eye experiment 5 Main methods of Conducting Research You will take notes on your lecture outline handout about 5 different methods used by psychologists to test their hypothesis and learn more about human behavior and mental processes Method Case study Naturalistic observation Surveys How it works Strengths weaknesses Method How it works Strengths weaknesses example example Correlation studies Negative correlation Positive Method Experiment How it works Strengths weaknesses Methods • Research question • hypothesis • Ethical guidelines • Debrief definition example Methods • Independent variable • Dependent variable • Control group definition example Topic: Classical Conditioning Experiment: Pavlov and “Pavlovian Response” Russian Dr. Ivan Pavlov, M.D. (1849-1936) studied effects of external environment on reflex responses “Classical conditioning focuses on the learning of involuntary emotional or physiological responses such as fear, increase heartbeat, salivation, or sweating, which are sometimes called reflexes because they are automatic responses to stimuli” * 1. Pavlov’s research question: Can an animal learn to associate a neutral stimulus with an unconditioned stimulus so that it has a reflex response to the neutral stimulus? Classical conditioning terminology Conditioned response (CR) :The behavior that the experimenter is trying to elicit from the subject salivation Neutral stimulus (NS): A stimulus (sight, sound, smell, feeling) that does NOT elicit desired response prior to conditioning. Sound of bell Unconditioned stimulus (US): a stimulus that leads to an involuntary response by a subject without any training. Food • Acquisition is when the NS becomes conditioned stimulus (CS) • After repeated paired exposures of NS and US, NS becomes CS therefore subject begins behaving in same involuntary way it would to unconditioned stimulus (US) after US has been removed More classical conditioning terminology 1. Generalization: Stimulus similar to CS will elicit same CR What would this look like in Pavlov’s --Different bells elicit salivation experiment? 2. Discrimination: Animal learns to ignore stimuli that are similar to CS if similar stimuli never accompany original US What would this look like in Pavlov’s --Sound of different bell NEVER paired with food experiment? 3. Extinction: CR will stop after repeated exposure to CS without US What would this look like in Pavlov’s --Original bell rung many times withoutexperiment? exposure to food Video clip The Office Clip 2 “quack” 1920 John Watson experiment “Baby Albert” video Identify the classical conditioning variables in Quack and the Office Quack • NS: quack sound • US: feeling of dart hitting body • UR: • CS: flinching when hit • CR: quack sound flinching when hearing quack The Office NS: computer reboot sound US: altoid on tongue UR: refreshed tongue CS: computer reboot sound CR: tongue anticipating altoid Watson’s little Albert experiment • Procedures: ▫ US: ▫ NS: ▫ CR: • Why is this considered an unethical experiment? • What did Watson conclude based on data of his experiment? Practical applications of Pavlovian Response In simple terms: you can train an animal (and a person) to respond in a desired way (perform a behavior or extinguish a behavior!) by training the person to associate desired (or undesired) behavior with a simple stimulus. For example: ▫ stop coyote from eating sheep by poisoning sheep carcasses ▫ eliminating phobias through systematic desensitization – Topic: Authority and Obedience Experiment: Dr. Stanley Milgram’s “shock” experiment 1. Research question: 2. Hypothesis: 3. Procedures: a) Assign test subject role of teacher and confederate role of learner b) Subject is told to deliver increasing voltage of electric shock to “memory test learner” in adjacent room every time learner makes a mistake c) As screams and pleads of “stop” are heard, subject is told by authority figure (psychologist in labcoat) to “please continue.” Topic: Authority and Obedience Experiment: Dr. Stanley Milgram’s “shock” experiment 4. Data 5. Conclusion: *experiment has been criticized for not following standard experimental protocol so data not entirely valid Topic: Conformity to social pressure Experiment: Dr. Solomon Asch line experiments 1. Research question: 2. Hypothesis: (Unknown) 3. Procedures: a. b. c. d. 50 male college volunteers tested Each test subject put into group with 7 confederates Confederates told to lie about line in 12 of the 18 trials Record response of test subject on each trial 4. Data: 5. Conclusion: Topic: Bystander Apathy Researchers: Darley and Latane • Research question: Are people more or less likely to help a stranger in need of help when they are in a large group setting? • Hypothesis: The presence of others lessens the chance that any one person will help the subject in need. • Read the reading to find the procedures and data and conclusions generated by Darley and Latane’s experiments Bystander effect (AKA apathy) : Why it happens… Conclusions from Darley and Latane’s experiments General rule: WHY? Topic: Social Learning (Observational Learning) Theory Experiment: Bandura’s Bobo doll experiment 1. Research question: How much do social modeling and reinforcement of behaviors affect an individual’s behaviors? (Read handout to find procedures, data, and conclusions for your notes chart) Procedures Data Bandura’s data/findings Bandura’s Bobo doll experiment 5. Conclusions • “Do as I say, not as I do” does NOT work!! ▫ Actions speak louder than words because we are mimickers Topic: Operant Conditioning Experiment: B.F. Skinner’s pigeon work 1. Research question: Does the environment shape animal behavior? 2. Hypothesis: Animal behavior can be shaped through reinforcement (reward) and punishment. 3. Procedures a. Reward pigeon with food every time it performs a desired behavior b. Punish pigeon with electric shock every time it performs undesired behavior 4. Conclusions: Practical Applications of Operant Conditioning ▫ Behavior modification (B-mod)– used in schools and by parents to get desired behavior to occur and eliminate undesirable behaviors Examples: Token economy— ▫ child earns stickers for good behavior that can be exchanged for a toy or privilege ▫ prisoner earns points for good behavior that can be exchanged for cigarettes/candy, extra privileges Teacher sticker charts/checks on board Zimbardo’s Stanford Prison Experiment 1. Zimbardo’s research question: How does environment and status affect people’s behavior? 2. Hypothesis (unknown) 3-5 watch video for procedures, observations, and conclusions Video Zimbardo’s Stanford Prison Experiment 3. Procedures 4. Data/observations Zimbardo’s study: What was learned? CONCLUSIONS • Guards will play one of 3 roles: ▫ Leader that tries to be mean, exploits power position ▫ Follower—goes along with leader’s cruelty ▫ Avoider—tries to ignore or escape the cruelty but does nothing to stop it • Prisoners do one of the following: ▫ submit to will/authority of guards ▫ try to rebel through hunger strikes, active rebellion ▫ do NOT tend to band together against injustices of guards ▫ Conclusion: The environment can cause people to do “bad” things and be quiet in face of injustice • Unethical? ▫ Zimbardo should not have played role of warden ▫ Zimbardo failed to protect emotional well being of both guards and prisoners Topic: The effects of “separate but equal” policies on the psyche of black children Experiment: Dr. Kenneth Clark “black doll or white doll?” • Research question: How young do children who are labeled inferior internalize that label? • Hypothesis: Policies like separate but equal and Jim Crow laws lead to internalized self-hatred and belief that one is inferior to white people • Procedures: a. Place a black doll and similar looking white doll in front of a black child. b. Ask the child which doll is the nice doll c. Ask the child which doll is the prettier doll What were the variables in the experiments we have learned about? • Zimbardo prison study ▫ IV: ▫ DV: • Milgram study ▫ IV: ▫ DV: • Asch’s conformity study ▫ IV: ▫ DV: • Bandura’s Bobo doll study ▫ IV: ▫ DV: What were the variables in the experiments we have learned about? • Blue eye experiment ▫ IV: ▫ DV: • Black doll, white doll experiment IV: DV:
