Question 2

What are multi level experiments

Question 2

What is the complex design racial bias situation?

Answer 2

Background: Racial stereotypes influence our judgment § Weapons priming task

• Method: quickly determine whether a stimuli is a gun or a tool
• But, each tool or gun target is preceded by a black or white prime
  face
• Results:
• Black primes increase at which people misclassify tool as gun
• Black primes speed up correct gun identifications
• (BUT if you give people more time, as in a full second, they won’t make mistakes anymore)
• Explanation:
• Seeing black (vs. white) faces activates threat-related stereotypes
• When threat is active, we can misperceive benign objects as threatening

Question 3

What is the modified racial bias task

Answer 3

Starting with validated measure of racial bias, but let’s simplify it to include only critical psychological ingredients

New operational definition of racial bias:
- Original: People judged weapons vs. tools
- Simplified: People judge faces as threatening or not
- Conceptual variables are the same: § Threat-related racial bias in judgment

Question 5

What is a 2x2 factorial design? Examples?

Answer 5

Manipulate 2 IVs, each having two levels
Example:
What is the effect of alcohol consumption on racial bias?
- IV 1 – Alcohol or placebo
- IV 2 – Picture of White or Black man
- DV – Evaluation of picture (positive or negative)
