Psychology: Class 11 — Chapter 2: Methods of Enquiry in Psychology

• Description: Attempting to describe a behavior or phenomenon as accurately as possible to distinguish it from other behaviors (e.g., defining study habits).
• Prediction: Forecasting the occurrence of a behavior under specific conditions based on established relationships between variables.
• Explanation: Identifying the causal factors or determinants that make a behavior occur, establishing cause-effect relationships.
• Control: Making a behavior happen, reducing it, or enhancing it by manipulating its antecedent conditions.
• Application: Bringing about positive changes in people's lives by solving real-world problems (e.g., using yoga to reduce stress).

Scientific research follows a systematic, objective, and testable procedure consisting of four major steps:

1. Conceptualising a Problem: Selecting a theme or topic, narrowing the focus, and developing a tentative answer called a hypothesis.
2. Collecting Data: Developing a research design (blueprint) regarding participants, methods of data collection, tools, and procedures.
3. Drawing Conclusions: Analyzing collected data using statistical procedures (e.g., graphical representations, measures of central tendency) to verify the hypothesis.
4. Revising Research Conclusions: Confirming, revising, or stating alternative hypotheses based on whether the data supports the initial theory.

• Scientific Paradigm: Assumes human behavior is predictable, caused by internal/external forces, and can be objectively observed, measured, and controlled. It focuses primarily on overt behavior.
• Interpretive Paradigm: Emphasizes understanding subjective experiences, feelings, and meanings over mere explanation and prediction. It views reality as subjectively constructed and context-dependent.

A powerful tool for describing behavior, consisting of selection, recording, and analysis of data.

• Naturalistic vs. Controlled Observation: Naturalistic observation occurs in real-life settings without observer manipulation, while controlled observation takes place in highly regulated environments like laboratories.
• Non-Participant vs. Participant Observation: In non-participant observation, the researcher observes from a distance without interfering. In participant observation, the researcher becomes an active part of the group being observed.

Conducted to establish cause-effect relationships between variables in a controlled setting.

• Independent Variable: The variable manipulated or altered by the researcher (the cause).
• Dependent Variable: The variable on which the effect of manipulation is observed (the effect).
• Experimental Group: The group exposed to the independent variable manipulation.
• Control Group: The comparison group treated identically except that the manipulated variable is absent.

Determines the strength and direction of the relationship between two variables without manipulating them. The relationship is represented by a correlation coefficient ranging from +1.0 through 0.0 to -1.0.

Used to study opinions, attitudes, and social facts using structured techniques.

• Personal Interviews: Can be structured (standardized questions, close-ended) or unstructured (flexible, open-ended).
• Questionnaires: Self-report instruments consisting of predetermined open-ended or closed-ended questions.
• Telephone Surveys: Quick data collection method, though prone to uncooperativeness and sampling bias.

An objective and standardized instrument used to assess an individual's standing in relation to others on mental or behavioral characteristics.

• Reliability: Consistency of scores obtained by an individual on the same test on different occasions (test-retest) or internal consistency (split-half).
• Validity: The degree to which a test measures what it claims to measure.
• Norms: Standardized average performance levels of a target group used for comparison.
• Types of Tests: Classified by language (verbal, non-verbal, performance), administration (individual, group), and difficulty (speed, power).

An in-depth, detailed investigation of a single individual, group, institution, or specific event using multiple data collection methods (interviews, observations, tests).

Converts psychological attributes into numbers. It utilizes statistical methods (mean, median, mode, standard deviation, correlation) to analyze close-ended responses and draw objective conclusions.

Analyzes descriptive, non-numerical data (narratives, field notes, unstructured interviews). It uses techniques like Narrative Analysis and content analysis to identify thematic categories and subjective meanings.

1. Lack of True Zero Point: Unlike physical sciences, psychological measurements do not start from absolute zero (e.g., no one has zero intelligence). Scores are relative.
2. Relative Nature of Psychological Tools: Tests are context-bound and culturally specific; a test designed for urban students may not be valid for tribal children.
3. Subjective Interpretation of Qualitative Data: Qualitative analysis is highly susceptible to researcher bias and subjective interpretation.

• Voluntary Participation: Participants must have the freedom to choose whether to participate and the right to withdraw at any stage.
• Informed Consent: Participants must be fully informed about the study's nature and potential risks before data collection begins.
• Debriefing: Reassuring and providing necessary information to participants after the study, especially if deception was used.
• Sharing the Results: The moral duty of the researcher to share findings with the participants.
• Confidentiality: Safeguarding participants' privacy by keeping all collected data strictly confidential.
