Study Notes

Purpose of Literature Review and Hypothesis Development

  • The purpose of a literature review in psychological research is to critically evaluate existing research on a research topic.
  • After developing a testable hypothesis, the next step in the scientific method is to design a study to test the hypothesis.

Research Design and Data Analysis

  • The step that involves placing raw data in statistical equations to support a hypothesis is called data analysis.
  • The main purpose of operationally defining variables in psychological research is to clearly specify the variables being measured and how they will be measured.
  • Reliability measures the consistency of a measurement tool or method in producing similar results.

Research Ethics

  • The term 'generalizability' refers to the extent to which research findings can be applied to other populations or contexts.
  • If a researcher does not provide informed consent to participants, the ethical principle of autonomy is violated.
  • The main role of an Institutional Review Board (IRB) in research studies is to ensure that the study is conducted ethically and protects the rights and welfare of participants.
  • Research ethics involve balancing a researcher's right to study behavior with the rights and welfare of participants.

Correlation and Experimental Research

  • The main difference between positive and negative correlation is the direction of the relationship between variables.
  • In experimental research, the purpose of a control group is to provide a baseline or comparison group against which the experimental group can be compared.
  • A placebo in an experimental study is a neutral or inactive treatment used as a comparison to a real treatment.

Study Designs

  • Cross-sectional research measures individuals of different ages at one point in time.
  • Longitudinal research is distinguished from cross-sectional research in that it involves measuring the same individuals over time.
  • Voluntary participation is a research design feature that ensures participants can withdraw from the study at any time.
  • Informed consent ensures that participants are informed about the purpose, risks, and expectations of a study.

Biopsychology and Null Hypothesis

  • The focus of study in biopsychology is the relationship between the brain and behavior.
  • The purpose of the null hypothesis in statistical analysis is to provide a hypothesis that there is no significant difference or relationship between variables.

Test your knowledge about psychological research methods based on the scientific method. Learn about studying human behavior and mental processes scientifically and objectively. Explore the steps of the scientific method, including literature review and replication of studies.
