- Content Analysis
- Method of organizing data into categories used to summarize information from a narrative record.
- Protocol Analysis
-
A type of Content Analysis.
Used when a psychologist is interested in the cognitive processes involved in a problem solving task. Requires the Subject to "think aloud" and then information is coded.
Remember Ericsson :) - Behavioral Sampling
- Looking at specific aspects of behavior instead of a complete record.
- Interval Recording
-
Recording divided into equal intervals of time.
i.e., measuring blood pressure at 10 minute intervals - Event Recording
-
Recording behavior each time it occurs.
i.e., recording the number of times a subject uses his eraser during an exam - Situational Sampling
- Observing behavior in different settings. Known to increase generalizability.
- Sequential Analysis
- Coding behavior sequences rather than isolated events. Used to study complex social behaviors.
- Quasi-Experimental Vs True Experimental Research
- Only True experimental research provides enough control necessary to conclude that the observed variability in a DV is actually caused by the IV. RANDOM ASSIGNMENT is the key.
- Random Assignment
-
The random assignment of subjects to different treatment groups (different levels of the IV)
**True experimental research uses Random Assignment** - Random Assignment Vs Random Selection
-
Random Assignment distinguishes between true and quasi experimental research. Allows researcher to be more certain that the DV is varying due to the IV
Random Selection enables the researcher to generalize her findings from the sample to the actual population.
