Common Methodologies in GSEP Research

Welcome, 

This guide aims to provide an overview of various research methodologies most frequently encountered in graduate psychology research studies.

1. Experimental Methodology:

The experimental method involves manipulating one variable (independent variable) to observe the effect it has on another variable (dependent variable), while controlling for extraneous variables. It is used to establish cause-and-effect relationships between variables in controlled laboratory settings.

Key Concepts: Randomization, Control Group, Experimental Group, Internal Validity.

2. Survey Methodology:

Description: Surveys involve collecting data from a sample of individuals through questionnaires or interviews, with the aim of generalizing the findings to a larger population. It is commonly used in psychology to gather information on attitudes, behaviors, and opinions from diverse populations.

Key Concepts: Sampling Techniques, Questionnaire Design, Reliability, Validity.

3. Observational Methodology:

Description: Observational studies involve systematically observing and recording behavior in naturalistic settings without intervening or manipulating variables. This method is used to study behavior in real-world contexts, offering insights into naturally occurring phenomena.

Key Concepts: Participant Observation, Non-Participant Observation, Ethnography, Observer Bias.

4. Case Study Methodology:

Description: Case studies involve in-depth examination of a single individual, group, or phenomenon, utilizing various data sources such as interviews, observations, and archival records. Case studies are valuable for exploring complex or rare phenomena in-depth, providing detailed insights into specific cases.

Key Concepts: Rich Description, Longitudinal Analysis, Generalization.

5. Correlational Methodology:

Description: Correlational studies examine the relationship between two or more variables without manipulating them, focusing on the extent and direction of their association. This method identifies patterns and associations between variables, informing predictions and further research directions.

Key Concepts: Correlation Coefficient, Directionality, Third Variable Problem.

6. Qualitative Methodology:

Description: Qualitative research focuses on understanding and interpreting subjective experiences, meanings, and social processes through methods such as interviews, focus groups, and textual analysis. The qualitative method provides nuanced insights into individuals' perspectives, cultural contexts, and social phenomena, often used in exploratory or theory-building research.

Key Concepts: Thematic Analysis, Grounded Theory, Reflexivity, Saturation.

7. Mixed Methods:

Description: Mixed methods research combines qualitative and quantitative approaches within a single study, allowing researchers to triangulate findings, enhance validity, and gain comprehensive understanding. Mixed methods offer the flexibility to address complex research questions by leveraging the strengths of both qualitative and quantitative methodologies.

Key Concepts: Integration, Sequential Design, Convergence, Expansion.

8. Quantitative Methodology:

Description: Quantitative research involves collecting and analyzing numerical data to test hypotheses, identify patterns, and quantify relationships between variables using statistical techniques. This method is widely used in psychology to investigate relationships, trends, and causal effects through numerical data analysis.

Key Concepts: Hypothesis Testing, Descriptive Statistics, Inferential Statistics, Measurement Scales.

9. Longitudinal Methodology:

Description: Longitudinal studies involve collecting data from the same participants over an extended period, allowing researchers to observe changes and trajectories of variables over time. Longitudinal studies are used to investigate developmental processes, life transitions, and long-term effects of interventions or treatments in psychology.

Key Concepts: Panel Designs, Cohort Studies, Attrition, Retention Strategies.
