Study Notes
Psychological Research - Overview
- Psychological research is a systematic process used to gather and analyze information about human behavior and mental processes.
- Research goals include understanding, explaining, predicting, and potentially controlling behavior.
- This process includes specific steps like observation, hypothesis formation, experiments, and analysis.
- The scientific method is a key approach in psychological research involving systematic study.
Objectives of Psychological Research
- Introduction to the scientific method.
- Introduction to conducting psychological research.
- Exploring ethical principles of research.
Importance of Research
- Every aspect of human life is based on research and exploration.
- Research plays a crucial role in validating claims and ensuring accurate understanding of the world, avoiding misinformation and inaccuracy.
- Scientific research is empirical; relying on objective and tangible evidence that can be validated regardless of the observer.
What is Scientific Research?
- A method for learning about the world through the application of critical thinking and tools like observation, experimentation, and statistical analysis.
Observation
- Scientific process starts with observations of natural phenomena
- Observation leads to questions and problems to be addressed.
- Inductive and deductive reasoning are critical for forming a theory
Theory
- Well-established explanation of phenomena based on interconnected concepts and propositions.
- Aims to explain, predict, and understand observed patterns and behaviors within a specific domain.
- Usually, supported by multiple studies and considered generally accepted within the field.
- Essential for interpreting and understanding data.
The Process of Scientific Research
Inductive Reasoning
- Drawing a general conclusion from specific observations.
- Example: Observing many fruits grow on trees and concluding that fruits generally grow on trees
Deductive Reasoning
- Making specific predictions based on general principles or premises.
- Example: All living things require energy, ducks are living things; therefore, ducks require energy.
Scientific Method Application
- Scientists use deductive reasoning to form theories and hypotheses.
- Hypotheses are tested through empirical observations.
- Inductive reasoning is used to draw conclusions from observations, potentially leading to new theories, hypotheses, or generalizations.
Research Process
- Prediction: Researchers make specific predictions about outcomes based on the hypothesis; these predictions allow for empirical testing.
Hypothesis Formation
- Tentative prediction or explanation based on observations and existing knowledge.
- Serves as a basis for further investigation.
- A good theory must have a testable prediction or hypothesis.
- Hypothesis are often "if-then" statements.
- Hypotheses must be falsifiable; meaning they can be disproven.
Hypothesis
- All hypotheses must be falsifiable; meaning they can be disproven.
- Falsifiability means that if a hypothesis is false, some observations or experiments can produce results contradicting the hypothesis.
Experimentation
- Researchers design and conduct experiments to test predictions.
- Experiments manipulate variables while keeping other factors constant, measuring the effect on another variable.
- Variables are elements identified by hypotheses.
- Two main types of variables: independent variable and dependent variable.
Variables
Independent Variable
- Variable that's manipulated or controlled by the experimenter.
- Key differentiator between an experimental group and a control group.
- Factor expected to cause an effect or change in the dependent variable.
Dependent Variable
- The variable measured by the researcher.
- Shows the effect or outcome of changes made to the independent variable.
- The researcher examines this variable to determine the independent variable's influence.
Validity
- Experiment goal is to make sure it's valid.
- Validity refers to the extent to which a test measures what it is supposed to measure.
Data Collection and Analysis
- Researchers collect data during experiments to assess outcomes and test predictions.
- Statistical techniques are used to evaluate results and determine if they support or reject the hypothesis.
Types of Data Collection
- Primary: Collecting data directly from individuals (e.g., surveys, interviews, observations)
- Secondary: Using existing data from other studies (e.g., government reports, published studies)
Data Collection Methods
- Surveys
- Interviews
- Observation
- Focus groups
- Document analysis
- Social media monitoring
Analyzing the Results
- Data analysis involves statistical techniques that evaluate collected data to interpret its meaning
- Conclusions are drawn based on results and alignment with original research questions and hypotheses.
- Factors considered include statistical significance, potential biases, and research design.
Key Steps to Analyzing Data
- Data Cleaning & Organization: Identifying errors and inconsistencies; Organizing data.
- Descriptive Statistics: Calculating measures like mean, median, mode, and standard deviation, for data summary.
- Inferential Statistics: Applying statistical tests to determine if observed relationships between variables are statistically significant, allowing for generalizations to a larger population.
Interpretation of Results
- Meaning of results interpreted based on context of research questions and established literature.
- Patterns, trends, and relationships within data are identified.
- Conclusions regarding the hypothesis are drawn by researchers.
- If the results support the hypothesis, it may be considered provisionally accepted.
- If the results do not support the hypothesis, the hypothesis may be revised, rejected, or new hypotheses may be developed for further investigation.
Important Considerations when Analyzing Research Results
- Research Design: How the design (e.g., experimental, correlational) affects the interpretation of results.
- Sample Representativeness: Assess if the study reflects the intended population.
- Bias: Identify potential sources of bias in data collection, analysis, and interpretations, and discuss their impact on findings.
- Effect Size: Practical significance of findings (beyond statistical significance)
