Basic Process / Concept in Research
What is Research? Definition & Real-Life Process
📖 Definition of Psychological Research
Research is a systematic, controlled, empirical, and critical investigation of hypothetical propositions about presumed relationships among natural and psychological phenomena. It is driven by curiosity and structured scientific inquiry.
"Do students focus and retain information better while studying in the morning or in the evening?" — This everyday inquiry becomes a scientific research problem when investigated through systematic observation and measurement.
The 4 Core Operations in the Research Cycle:
Forming a Question
Identifying a specific problem, curiosity, or testable research query.
Collecting Data
Gathering empirical evidence through standardized tests or observation.
Analysing Data
Applying statistical tools to process numerical findings and test hypotheses.
Understanding Results
Interpreting inferences, drawing conclusions, and modifying existing theory.
5 Core Criteria / Characteristics of Good Research
1. Empirical
Based strictly on real-life evidence and concrete observations rather than personal opinions, intuition, or unverified claims.
2. Valid & Verifiable
Employs precise instruments and reliable measurement. Anyone checking the data using the same procedures can verify the results.
3. Logical
Guided by strict rules of reasoning using both Induction (specific facts → general principle) and Deduction (general theory → specific hypothesis).
4. Theory-Developing
Formulates broad generalizations and theoretical frameworks that extend well beyond immediate, isolated observations.
5. Replicable
The research design, sample selection, and procedure are documented with such clarity that independent researchers can repeat the study under identical conditions and obtain consistent findings.
Research Process: Basic Considerations
Context of Discovery
The initial, creative phase of research where new ideas, insights, questions, and hypotheses are born out of curiosity, intuition, or literature review.
Context of Justification
The empirical testing phase where hypotheses are subjected to rigorous data collection, statistical verification, and peer review to defend and share results.
⚙️ Role of Theories, Hypotheses, and Paradigms
Research Biases & Scientific Attitudes
⚠️ 4 Major Types of Research Biases
Influenced by personal beliefs, values, or political views.
Distortions arising from observer expectations or selective perception.
Researcher subtly communicating expected outcomes to subjects.
Subject's belief in a treatment altering actual responses.
🌟 3 Core Scientific Attitudes
Motivated by the passion to question the unknown and explore underlying phenomena.
Critical attitude requiring empirical verification before accepting conclusions.
Willingness to share data, protocols, and accept public verification or refutation.
Objectivity Safeguards in Psychological Research
Procedural Safeguards
Keeping meticulous, detailed step-by-step records of all experimental conditions, timing, and data collection procedures to enable transparent auditing.
Standardisation
Enforcing uniform, identical instructions, testing environments, apparatus setups, and scoring rubrics across all subjects without deviation.
Operationalisation
Defining abstract psychological concepts (e.g. anxiety, intelligence) strictly by the concrete, observable operations used to measure them.
Avoiding Bias
Utilizing single-blind, double-blind, control group, and placebo-control designs to isolate variables and eliminate confounding errors.
The 9 Sequential Steps in Research Process
"I F I C R D-S A C-P"
(Identification → Formulation → Identifying Vars → Design → Research Tools → Data/Sample → Analysis → Conclusions → Publication)
Detailed Breakdown: Steps 1 to 5
Ask a question or identify a need arising from curiosity. Rephrase the problem meaningfully. Evaluate feasibility considering available funds, time, and expertise. Review literature to avoid duplication.
Develop a tentative, testable statement predicting relationships between variables based on theory, previous research, or observation. Formulate prior to data collection.
Define Independent Variables (IV), Dependent Variables (DV), and Extraneous Variables. Use operational definitions to specify and measure variables clearly.
Create a blueprint for testing hypotheses while ensuring maximum control of extraneous variables. Include logistical arrangements, sampling strategy, and timeframe.
Develop or select appropriate research tools (questionnaires, psychometric scales, observation schedules). Construct new tools if existing ones are unavailable.
Detailed Breakdown: Steps 6 to 9
Select a representative sample of the population. Choose appropriate data collection methods (experiments, surveys, observation). Administer tools individually or in groups, managing recruitment and training costs.
Analyse data using statistical (univariate, bivariate, multivariate) or qualitative techniques. Select parametric or non-parametric tests aiming to evaluate the null hypothesis ($H_0$) against alternative hypothesis ($H_1$).
Generalise findings to the target population. Relate conclusions to the original theory or previous research findings, modifying theories if new evidence requires it.
Document all research steps and findings clearly. Write a formal scientific report and publish it in scientific journals or public domains for wider community dissemination.
Importance of Research in Psychology
🌐 Core Applied Fields
- Learning & Motivation: Explores how humans/animals acquire skills and drivers of behavior.
- Perception & Memory: Investigates sensory processing, cognitive categorization, and memory retrieval.
- Practical Applications: Improved treatments for mental disorders, vehicle design, workplace performance & employee happiness.
🔬 Scientific Nature of Psychological Research
- Experimental Rigor: Experimental methods ensure systematic control and high scientific standards.
- Variable Control: Isolates the specific effects of Independent Variables while controlling extraneous factors.
- Quantitative Approach: Converts psychological facts into quantitative data for rigorous statistical analysis.
