Chapter 2: Doing Social Psychology Research – Study Notes

Introduction to Social Psychology Research

Why Should You Learn About Research Methods?

Research methods are fundamental to psychology as a science. Understanding these methods helps students critically evaluate information, reason about real-life events, and perform better academically. Psychology uses the same logic-based scientific process as other sciences, such as biology and chemistry.

• Consumer of Information: Enables critical evaluation of media and other sources.

• Improved Reasoning: Enhances ability to analyze real-life events and problems.

• Academic Success: Supports better performance on tests and in future courses.

Additional info: Mastery of research methods also facilitates understanding of scientific terminology used across disciplines.

Developing Ideas: Beginning the Research Process

Sources of Research Ideas

Ideas for research in social psychology originate from personal experiences, observations, current events, and previous research. Before starting a study, it is essential to review existing literature to ensure the idea is novel and relevant.

• Personal Experiences: Everyday interactions and observations.

• Current Events: News and societal trends.

• Previous Research: Builds on established findings.

• Electronic Databases: Provide access to a wealth of information for literature review.

Hypotheses and Theories

Definitions and Differences

Formulating hypotheses and theories is a critical step in the research process. They guide the design and interpretation of studies in social psychology.

• Hypothesis: An explicit, testable prediction about the conditions under which an event will occur. Hypotheses are based on observation, existing theory, or previous research findings.

• Theory: An organized set of principles used to explain observed phenomena. Theories are broader than hypotheses and are revised as new research emerges.

Research Cycle: The process typically moves from theory to research questions, to research design, to hypotheses, to data collection and analysis, and back to theory refinement.

Research Methods and Experimental Design

Key Terminology

• Research Methods: Approaches to observation, measurement, manipulation, and control of variables in empirical studies.

• Experiment: Manipulation of one variable under controlled conditions to observe changes in another variable, allowing for cause-and-effect relationships.

Example of a Simple Experiment

To illustrate experimental design, consider a study investigating whether people eat more when served a larger bowl of food.

• Hypothesis: Those who get a larger bowl of food will eat more than those who get a smaller bowl.

• Consistency: The type of food must be the same for all participants (e.g., pasta).

• Experimental Procedure: Participants are randomly assigned to receive either a large or regular bowl of pasta. The amount eaten is measured.

Example: Half the participants receive a large bowl, half receive a regular bowl. The dependent variable is the amount of pasta eaten.

Variables in Experiments

• Independent Variable (IV): The manipulated variable (cause). In the example, this is the bowl size.

• Dependent Variable (DV): The variable expected to be influenced by the IV (effect). In the example, this is the amount of pasta eaten.

Additional info: Random assignment helps control for confounding variables and increases the validity of causal conclusions.
