Step 1 of 3

Notes for Exam 2 ETHICS - Unethical studies o (monster study)  Wendell Johnson Stuttered  He wanted to know why people stuttered  “stuttering is a learned behavior”  Participants fluent orphans and demi-orphans  Pre- measure measuring verbal fluency  Independent variable he took 12 “fluent kids”  6 were told that they were stutterers  6 were “normal fluent speaker”  Dependent Variable people were brought and they examined how well the kids spoke  Results no significant results (no support to hypothesis)  The people who were told that they were stutterers were less- confident speakers and sued o Stanley Milgram’s obedience to Authority study  WWII “how could the German soldiers commit such horrible things in the Genocide”  Hypothesis they did it because of authority  “Will participants follow authority even if it means hurting someone”\  Experimenter authority (in a white lab coat)  Participant teacher  Confederate learner  Learning phrase pair of words said  Testing phase one words given, and the confederate said the other  Outcome measure how many men will go all the way on the shock (%)  Results 65% of men went all the way o “Does physical proximity with another person increase physiological arousal”  Occurred in men’s bathroom  IV confederate followed man and stood next to him while urinating  Half picked urinal one away  Half picked urinal two away  Control no confederate  DV how long it took for the man to pee - Ethical standard 8 o Institutional Approval- IRB (institutional review board) what researchers need to follow  Ethically  Must be more than 5 people  One member must be a scientist  One member must have an academic interest outside of science  Member of the m=community less bias - Informed consent tell participants how long it’s going to take… o What they’re going to be doing o What’s going to be upsetting o That they can stop whenever they want o Contact information if there is unethical occurrences o That their information is confidential - We now have a cost-benefit analysis - APA: 5 general principles o 1. Beneficence and non-maleficence don’t cause suffering o 2. Fidelity and responsibility establish trust with their participants and take responsibility if they do something wrong o 3. Integrity strive to be accurate and honest o 4. Justice treat people equally o 5. Respect for others rights and dignity make sure the participants are old enough - Why do we use deception o Telling participants a false objective of the study allows for natural responses o You need to debrief them afterwards MEASUREMENTS - Observable measures smile, heartrate - Abstract psychological measures self-esteem, cognition, emotion, behavior - Conceptual definition dictionary definition - Operational definition questionnaire that measures construct (measures/manipulations/conceptual definition) - Measures in psychology is reducing a psychological, behavioral, or physiological phenomena into a number so we can do stats on the numbers (data to work with) - Categorical data categories (man vs woman) - Continuous data the number has meaning/ scale - Self-report measures: o Explicit filling out questionaries’ o Implicit gut reaction, unconscious properties o Explicit self-reports from judges Judges rate - Question types: o Open-ended you can write as much as you want o Forced-choice respond to given answers (Y vs N) o Likert Scale/Likert-type scale rate on a scale o Semantic differential on a scale, but there is one extreme on both sides (pain _ _ _ _ no pain) o Implicit self-report gut reaction  IAT  Study: white participants who took the IAT and experienced to white and black experimenter, who did they smile the most at, or get the closest to o Explicit self- reports form judges someone is asked to come in and judge someone’s personality, self-esteem, etc.  Study (track boys aggression for 6 years (4 to 10 grade)  Aggression went down over time - Ethics related to researcher o Reporting accurate results o Date fabrication making up data to support your hypothesis  Example: Diederik Stapel
