Study Notes

Research Methodology Terms

  • Ecological Validity: Determines how well research findings can be applied to real-life scenarios.
  • Demand Characteristics: Participants’ altered behavior due to awareness of being part of an experiment.
  • Aim: The purpose of a study regarding the effect of the independent variable (IV) on the dependent variable (DV).
  • Experimental Hypothesis: A statement predicting the relationship between the IV and the DV.
  • Confounding Variables: Unwanted variables that impact the relationship between the IV and DV, potentially skewing results.
  • Researcher Bias: Influence of the researcher's expectations on study outcomes, consciously or unconsciously.
  • Participant Variability: Influence of participant characteristics on the DV, which may distort research results.

Sampling and Population Concepts

  • Target Population: The specific group of individuals whose behavior a researcher aims to study.
  • Representative Sample: A sample that accurately reflects the broader population.
  • Stratified Sample: A type of sampling where participants are randomly selected from different subpopulations.

Ethical Considerations in Research

  • Informed Consent: Participants must understand the study's nature and willingly agree to participate.
  • Deception: Participants may not be fully aware of the study's aims to reduce bias from demand characteristics.
  • Debriefing: The process of revealing the study's true purpose to participants after it concludes.
  • Withdrawal from a Study: Participants should be made aware of their right to exit the study at any time.
  • Confidentiality: Ensures that all information collected in the study remains private.
  • Protection from Harm: Fundamental ethical obligation to prevent physical or psychological harm to participants.

Research Validity and Reliability

  • Validity: Measures whether the research accurately assesses what it claims.
  • Cross-Cultural Validity: Assesses the relevance of a study to multiple cultures, avoiding ethnocentrism.
  • Ethnocentric: A viewpoint that considers one culture as superior, impacting generalizability.
  • Reliability: The reproducibility of research results under similar conditions.

Data Collection Methods

  • Triangulation: Combining qualitative and quantitative research methods to enhance data richness.
  • Deductive Approach: Testing a hypothesis derived from a theory against empirical evidence.
  • Inductive Approach: Develops hypotheses without predefined variables, focusing on data trends.

Bias and Observation Types

  • Participant Bias: Adjustments in responses based on perceived appropriateness or expectations.
  • Social Desirability Bias: Participants' tendencies to provide favorable responses, skewing true data.
  • Overt Observation: Researcher identity known to participants, influencing behavior.

Experimental Design Techniques

  • Repeated Measures: Each participant experiences all conditions of the experiment for comparative analysis.
  • Independent Groups: Different groups for each condition, facilitating comparison of results between them.
  • Matched Pairs: Participants are paired based on specific characteristics to ensure balance across conditions.
  • Single Blind Control: Participants are unaware of the study’s purpose to minimize bias.
  • Double Blind Control: Both participants and researchers do not know specific study details to prevent biases from influencing results.
