Unit 2

Research Methods
-psychology is a science
Hindsight Bias
-The tendency to believe, after learning the outcome, that you knew it all along
Overconfidence
- we tend to think we know more than we do
The Banum Effect
-the tendency for people to accept very general or vague characterization a of themselves and take them to be aware

Applied v. Basic Research
Aplied- has clear, practical applications
Basic- explores questions that you may be curious about, but not intended for immediate use

Hypothesis
- expresses a relationship b/t 2 variable
-variables- anything can vary among participants in a study

Independent Variable- what is being manipulated in the experiment
Dependent Variable- what is being measured in the experiment

Operational Definitions
-explain what you mean in your hypothesis
-how will the variables be measured in "real life" terms

Types of Research

  • Descriptive- and research that observes and record
  • Correlation
  • Experiment
Descriptive Research 
  • case study- a detailed picture of one of or a few subjects
  • the survey- most common; measure correlation; use mail, internet, etc. 
  • Naturalistic Observation- watch subjects in their natural environment
Random Sampling
  • identify population you want to study
  • the sample must be representative of the population you want to study
  • false consensus effect- tendency to overestimate the extent to which others share out beliefs and behaviors
Hawthorne Effect
  • Just the fact that you know you are in an experiment can cause change
Correlation Methods
  • correlation expresses a relationship between two variables
  • does not show causation
  • correlation coefficient 
    • a number that measures the strength of a relationship 
    • the relationship gets weaker the closer you get to zero
  • Types of correlation
    • positive: the variables go in the SAME direction
    • negative: the variable go in the OPPOSITE direction
Experimental Research
  • explores cause and effect relationships
    • experimental group- exposes participants to the treatment
    • control group- comparison for evaluating  the effect
Blind study- subjects are unaware of assigned to experimental or control group
Double-blind study- neither the subjects nor experimenters know which group is control or experiimental
Inferential Statistics- are used to make an inference or drow a conclusion beyond the raw data
Standard Deviation
  • how must scores vary around the mean
  • high- scores are spread out
  • low- score are close
