In what 4 ways do we gain knowledge? (TATES)
Tradition
Authority
Trial & Error
Scientific Method
What process is being stated?
- Identify a research question
- Design study
- Data collection
- Data analysis
- Communication of results
Scientific Method
What are the 2 types of experimental design? (TeQe)
True Experimental
Quasi Experimental
Describe a true experimental design
experimental group compared to control
participants randomly sampled and assigned
What is being described?
- Control groups
- Random assignment
- Blind/double blind
- Rosenthal effects
- Interpretation of results
- Exact measurements
Objectivity
What are the types of Reliability? (PrMrIrVr)
- Participant reliability
- Measurer reliability
- Instrument reliability
- Variable reliability
Valid measurement must be reliable but reliable measurements may not be valid
Validity
Types of validity (IvEvEv)
- Internal validity
- External validity
- Ecological validity
most common score
mode
middle score
median
average score
mean
measure of how far away from the target and in which direction
Constant Error
- Measures accuracy and bias
- CE = trial score - criterion goal
- Mean CE represents average magnitude of movement and deviation of results - be aware of cancelation effects
Constant Error
Measure of how far away from the goal = absolute value error score (always positive)
Absolute Error
- AE |trial score - criterion goal|
- Represent overall accuracy of subject
- Mean AE represents mean error score of subject
Absolute Error
Measure of consistency - spread of scores about your own average score
Variable Error
Measure of consistency with respect to the actual target - spread of scores about the actual criterion goal
Total Error
measure the strength of the relationship between variables
Correlations
Stimulus detection and Response program
Simple RT
Stimulus detection, stimulus recognition, response selection, response program
Choice RT
stimulus detection, stimulus recognition, response program
Go/No Go RT
_____ indicates that RT increases proportionally as the number of choices double
Hicks Law
Changing the number of alternatives into _____ by using Log2 is what gives us the linear relationship
