Card Set Information
research experiments hypothesis
1. “Hypotheses must be…”
a. Testable-if a hypothesis does not generate any observational tests, there is nothing that a
scientist can do with it-you must be able to test it by conducting some sort of experiment.
b. Falsifiable- A hypothesis must be able to proven wrong, cannot be a definite yes/no or correct/false
c. Precise-Must be exact
d. Rational-It has to make sense and be logical.
e. Parsimonious-It must be simple and understandable
What are the 3 sources of hypotheses?
What are the 6 steps of hypothesis testing?
1. Form hypothesis from theory, model, or observations
2. Design study to test hypothesis
3. Derive predictions
4. Conduct study and test predictions
5. Confirm or revise hypothesis depending on observations
6. Modify theoretical concepts
What is the Watson Selection test?
-Developed as a tst of logical reasoning
-Used by psychologists to study structure of human reasoning
-A logic puzzle formally equivalent to a question that ass about four cards with numbers/colors
-A response which identifies a card which need not be inverted, or a response which fails to identify a card which needs to be inverted are both wrong
-The original task dealt with numbers (even/odd) and letters (vowels,constants)
What is conditional reasoning?
Based on and 'if A then B' construct that points B to be true if A is true
Leaves open the question if A is false
Denying antecedent (making assumptions about what happens if A is false
: If it is training, I will get wet, and it is not raining, but then something else could happen)
Denying consequent - if B is false, then A must also be false
Affirming consequent - A and B are both true.
What are the 2 ways to properly test a conditioning statement?
What are the order effects?
The order in which the subject is placed in an experiment affects the data
Fatigue - subjects become upset, tired, and frustrated if kept for a long time
Practice -subjects become accustomed to conditions and perform well as a result, skewing results
