"CLASSIC" SOCIAL PSYCHOLOGY EXPERIMENT



Asch's Conformity study





Experimenter measured: degree of conformity

ie., whether subject went along with group vs. giving obviously correct answer

Results: almost 40% conformed!!

EXPERIMENTAL METHODS



Step 1: Theory

Does Disgrace cause an increase in admiration?





Step 2: Clarify variables

Independent variable Dependent variable








Step 3: Hypothesis via "Operational definition" of variables









Step 4:

Random Assignment (next oh)

Step 5:

Experimenter Manipulates IV to occur in 2 conditions:

Experimental Condition Control Condition








Step 4 + Step 5 is the Key to making "causal conclusions"

RANDOM ASSIGNMENT



Question: Does studying lead to good grades?

Non-random assignment:

GROUP 1: STUDYING



IQ IQ IQ IQ

IQ IQ IQ IQ ------------> As



GROUP 2: NO STUDYING

iq iq iq iq

iq iq iq iq ------------> Fs

Random assignment:

GROUP 1: STUDYING



iq iq iq iq -------------> As

IQ IQ IQ IQ

GROUP 2: NO STUDYING

iq iq iq iq -------------> Fs

ETHICS IN EXPERIMENTATION



Balancing act between:

Mundane Realism Experimental Realism
-is the experiment realistic ? Does the experiment absorb its participants?

Demand characteristics:Cues that give away the

purpose of the experiment

Balancing act requires INFORMED CONSENT

CRITICAL TOOLS

-operational definitions







-mundane realism







-experimental realism







-demand characteristics

Correlational Methods





Step 1:Theory:

Is there a relationship between disgrace and admiration?





Step 2: Clarify Variables

x y




Step 3: Hypothesis via Operational definition of variables













Step 4:

Random sampling for representative sample

WHAT IS CORRELATION?

Correlation Causation
x,y x ->y






Why? X, Y could be related for three reasons:









1. X -> Y





2. Y -> X



3. Z



X Y

Understanding correlation:

Critical Tools



-correlation vs. causation









-Does the questionnaire adequately operationally define variables?

Research Proposals



Step 1. Choose a study







Step 2. Think about it-what's wrong with it?







Step 3. Drafts-APA style



a. Title page

b. Abstract





c. Introduction-introduce your topic area in a clever way





- introduce the study, its purpose, and whatever about it that you will be criticizing ("Lit review")







-- criticize with resolutions



-end with hypothesis for your study





d. Methodology (APA format)
