Study Notes
Operationalization
- Operationalization is the process of turning abstract ideas into measurable observations.
- It's crucial for ensuring that experiments are measuring what they intend to.
- For example, the concept of social anxiety is not directly observable but could be operationally defined in terms of self-rating scores on anxiety, behavioral avoidance of crowds, or physical anxiety symptoms in social situations.
Operationalizing Variables
- Operationalizing variables means defining exactly what the independent and dependent variables are and how they are measured.
- This helps to ensure that experiments measure what they intend to measure.
Methods of Operationalisation
- Self-report: Participants rate themselves.
- Observation: Observers count or identify specific behaviors (e.g., number of smiles).
- Physiological measurement: Measuring physiological responses (e.g., heart rate, sweat).
- Interviewer rating: Based on responses to questions.
- Clinician assessment: Expert knowledge used to determine responses.
Importance of Specificity
- Operational definitions need to be specific enough that another researcher could replicate the experiment exactly.
- A ten-point happiness scale or measuring reaction time in seconds are examples of this specificity.
Independent and Dependent Variables
- Independent variable (IV): The variable the experimenter manipulates.
- Dependent variable (DV): The variable that is measured and is expected to change as a result of the IV.
- Operational definitions for both IV and DV need to be clear and precise in research design.
Examples
- Violent video games and aggression: An IV could be whether or not violent games are played or exposure to violence. A DV could be measured by observation and 10-point questionnaires or checklist observations.
- Milk and creativity: An IV is whether or not milk is drunk and a DV could be measurements of creativity.
Operationalizing Research Questions
- Examples of research questions requiring operationalisation include the time of day affecting student concentration, hunger affecting intelligence, or education levels affecting quality of life.
