Research Methods: The Scientific Process And Peer Review

Question 1

What is peer review

Answer 1

-is an essential part of this process whereby scientific quality is judged prior to publication

Question 2

Why is peer review important for scientists

Answer 2

-it is in the interest of all scientists that their work is held up for scrutiny and any work that is flawed or downright fraudulent (as in the ‘Cyril Burt affair’) is detected and the results of such research are ignored

Question 3

What was the Cyril Burt affair?

Answer 3

Who:
Cyril Burt was a British educational psychologist who studied intelligence and heritability in children.

What happened:
• Burt claimed that intelligence (IQ) was strongly inherited, based on studies of twins separated at birth.
• He reported very high correlations in IQ between identical twins raised apart, which supported the nature side of the nature–nurture debate.

The controversy:
• After Burt’s death, it was discovered that some of his data might have been fabricated.

•	Some co-authors he cited may not have existed, and the results were suspiciously consistent over time.

Impact:
• His case raised questions about ethics, data fabrication, and verification in psychological research.
• It showed the importance of replication and transparency in studies.
• It sparked debate over the heritability of intelligence, as later research suggested Burt’s findings were exaggerated.

Question 4

What is the scientific process

Answer 4

-the scientific process refers to the systematic methods psychologists use to investigate behaviour and mental processes in a rigorous, objective, and replicable way.

Question 5

Key Features of the Scientific Process

Answer 5

1. Observation 👀
   • Psychologists start by observing behaviour or phenomena to identify patterns or questions.
   
   2. Formulating Hypotheses 💡
      • A hypothesis is a testable prediction about the relationship between variables.
   3. Experimentation / Data Collection 🔬
      • Researchers design studies to collect evidence (quantitative or qualitative) using controlled methods.
   4. Analysis 📊
      • Data is analysed statistically or descriptively to see if it supports or contradicts the hypothesis.
2. Replication 🔄
   • Studies are repeated to check whether the findings are reliable and consistent.
   
   6. Theory Development 📚
      • Over time, evidence from multiple studies contributes to theories that explain behaviour or mental processes.
   7. Evaluation / Peer Review ✅
      • Research is critically evaluated for reliability, validity, and ethics, and findings are often published for scrutiny by other psychologists.

Question 6

The scientific process in psychology emphasizes:

Answer 6

• Objectivity – avoiding bias

•	Empiricism – based on evidence

•	Replication – repeating studies to check results

Question 7

The Parliamentary Office of Science and Technology (2002) suggests that peer review serves three main purposes:

Answer 7

1.Allocation of research funding
2.Publication of research in academic journals and books
3.Assessing the research rating of university departments

Question 8

How can the internet affect psychological research

Answer 8

-Provides easy access to journals, articles, and databases

-Allows researchers to share findings widely

-Enables online studies with participants

Question 9

What are advantages of the internet for research?

Answer 9

-Quick access to large amounts of information

-Can help replicate studies and compare findings

-Increases research efficiency

Question 10

What are disadvantages of the internet for research?

Answer 10

-Not all sources are reliable or peer-reviewed

-Risk of plagiarism

-Information may be misleading or biased

Question 11

Evaluate peer review (strengths)

Answer 11

-Ensures research is checked by experts, improving accuracy and credibility

-Helps catch errors or flawed methodology before publication

Question 12

Evaluate peer review (weaknesses)

Answer 12

-Can be biased if reviewers know the researcher

-Can delay publication

-Sometimes novel or unconventional ideas are rejected
