Verified courseTeaching note checked against the official specification.
Component 2: Ethics for Eduqas A-Level Psychology examines the ethical guidelines that govern psychological research, including informed consent, deception, protection from harm, confidentiality, privacy, and the ethical issues surrounding human and animal participants. Students must apply these principles to real and hypothetical studies, evaluating costs and benefits using frameworks such as the BPS Code of Ethics and Conduct.
Component 2: Ethics (knowledge, understanding and application of) explained
Component 2: Ethics (knowledge, understanding and application of) covers 8 specification points, including confidentiality and deception.

confidentiality
Confidentiality is the ethical duty to protect participants' personal information and to prevent their identity being revealed in research. It differs from anonymity: anonymity means the researcher cannot link data to a person, whereas confidentiality means the researcher can but promises not to disclose it. Practical safeguards include using participant codes instead of names, storing data securely, reporting group rather than individual results, and limiting access to raw data. Confidentiality can be breached when data are published in identifiable form, shared with third parties without consent, or when small samples make individuals recognisable. It may be overridden only in limited circumstances, such as a legal requirement or serious risk of harm, and participants should be told about this limit in advance.
deception
Deception in psychological research means deliberately withholding information from participants or actively misleading them about the true aim, procedure or measures of a study. It is assessed in Component 2 ethics as a potential ethical issue that must be identified and justified. Learners should distinguish deliberate withholding (for example, not revealing that a memory test also measures mood) from active misleading (for example, giving a false cover story about what a task measures). The key evaluative point is that deception can protect the validity of findings by preventing demand characteristics, but it conflicts with informed consent and may cause distress when revealed. Ethical review usually requires that deception be justified, minimal and followed by full debriefing.
risk of stress, anxiety, humiliation or pain
This ethical issue concerns the risk that participation causes psychological or physical harm: stress, anxiety, humiliation or pain. It is assessed in Component 2 ethics as a potential harm that researchers must anticipate, minimise and justify. Learners should recognise that risk can be psychological (for example, anxiety from being observed or from failing a task) or physical (for example, discomfort from a procedure), and that humiliation can arise from public exposure of poor performance. The key evaluative point is that researchers should assess the likelihood and severity of harm, take steps to reduce it (such as allowing withdrawal, using sensitive task design or providing support), and ensure participants leave in the same state as they arrived.
risk to the participants’ values, beliefs, relationships, status or privacy
This ethical issue concerns harm that is not physical: research can disturb what participants value, challenge their beliefs, damage their relationships, lower their status or expose their privacy. A study on obedience that makes a participant believe they have harmed someone may shake their self-image and their beliefs about themselves. A study of close relationships that asks about conflict may strain a couple's relationship if a partner learns what was disclosed. Asking about income, health or sexual behaviour risks privacy. Researchers reduce the risk by keeping questions to what the design needs, by anonymising and securely storing data, by warning participants about sensitive content in advance, by allowing them to skip questions or withdraw, and by debriefing so that any distress or misunderstanding is addressed.
valid consent
Valid consent means a participant agrees to take part freely and with enough understanding of what the study involves. Three elements make consent valid: the participant is informed about the purpose, procedure and any risks; the participant is competent, meaning able to understand and decide, which excludes young children or people with impaired capacity unless a guardian consents; and the agreement is voluntary, given without pressure or coercion. Researchers obtain consent through a consent form or verbal agreement, and for children they seek parental consent plus assent from the child. Deception can undermine valid consent because participants cannot agree to what they are not told, so studies using deception usually seek presumptive consent or prior general consent and debrief afterwards. Consent can be withdrawn at any time, and participants should be told this.
working with vulnerable individuals (including children)
Ethical research with vulnerable individuals, including children, turns on protecting people who may find it harder to give genuinely informed consent or to resist pressure. A psychologist identifies vulnerability before recruiting, then secures consent that is informed, voluntary and ongoing, using parental or guardian consent plus the child's own assent where a child is involved. The researcher minimises distress, keeps participation brief and age-appropriate, offers a clear right to withdraw at any point, and anonymises data. Debriefing restores participants to their prior state and signposts support. A concrete method is a pilot with a small comparable group to test whether instructions and tasks are suitable. Assessment rewards applying these safeguards to a described study and justifying them, not reciting a list.
working with animals
Ethical work with animals in psychology weighs scientific benefit against animal welfare. A researcher justifies why animals rather than humans are used, then applies the principles of replacement, refinement and reduction: replace animals where a valid alternative exists, refine housing, handling and procedures to minimise pain and stress, and reduce the number of animals to the minimum needed for statistical power. The researcher follows relevant legislation and licensing, uses skilled handlers, provides appropriate housing and enrichment, and considers species-appropriate care and humane endpoints. A concrete method is a pilot to check procedures cause minimal distress. Assessment rewards applying these safeguards to a described study and justifying them, not listing rules.
managing the risk posed by ethical issues (including the use of ethics committees and ethical guidelines)
Ethical risk management means identifying, before and during a study, the ways participants could be harmed or their rights breached, then reducing that risk to an acceptable level. Researchers do this by applying ethical guidelines such as informed consent, right to withdraw, confidentiality, protection from harm and debrief, and by submitting their proposal to an ethics committee. An ethics committee reviews the design, the materials and the consent arrangements, may require changes, and monitors serious departures from the approved protocol. Risk is judged against the likely benefit of the research, so a study with unavoidable mild stress needs stronger safeguards than a low-risk questionnaire. Managing risk is continuous: consent is re-checked, distress is monitored and debriefing is planned.

Component 2: Ethics (knowledge, understanding and application of) exam tips
Topic Overview
Component 2: Ethics covers the moral principles that guide psychological research involving human and animal participants. It explores core ethical guidelines such as informed consent, deception, protection from harm, confidentiality, privacy, and the right to withdraw, as well as the ethical treatment of animals. Students learn to apply these guidelines to real and hypothetical studies, evaluating the balance between scientific benefits and participant welfare.
This topic is essential for understanding how psychological research is conducted responsibly and how ethical considerations shape research design. It connects to other areas of psychology, including research methods, social influence, and clinical psychology, and is assessed through scenario-based questions that require application and evaluation. Mastery of ethics is crucial for achieving high marks in exams and for conducting ethical research in the future.
Key Concepts
- →Informed consent: participants must be given comprehensive information about the study's purpose, procedures, risks, and benefits before agreeing to take part, ensuring they can make an informed decision.
- →Deception: misleading participants about the true aim or procedures; it is only acceptable if it is necessary for the study and is fully debriefed afterwards, with no risk of harm.
- →Protection from harm: researchers must ensure participants are not exposed to physical or psychological harm greater than they would experience in everyday life; if harm is unavoidable, it must be justified and minimised.
- →Confidentiality and privacy: participants' data must be kept confidential and their privacy respected; personal information should not be shared without consent, and anonymity should be maintained where possible.
- →Ethical cost-benefit analysis: researchers must weigh the potential scientific benefits of a study against the ethical costs to participants, using frameworks such as the BPS Code of Ethics and Conduct to justify decisions.

Examiner Tips
- 💡Read the stem for the specific disclosure risk, such as named quotes or a small sample, and match the safeguard to it
- 💡Use the distinction between confidentiality and anonymity precisely, because options often swap the two
- 💡Check whether the scenario mentions consent or prior briefing about limits, since this affects whether the breach is ethical
- 💡Read the stem carefully to see whether it describes withholding information or actively misleading participants, then match the option to that description
- 💡Eliminate options that describe unrelated issues such as confidentiality or protection from harm when the question targets deception
- 💡When an option mentions debriefing, check that it is presented as a safeguard following deception rather than as a replacement for consent
- 💡Check whether the stem describes psychological or physical harm, then choose the option that matches that type of risk
- 💡Eliminate options that describe unrelated issues such as confidentiality when the question targets risk of harm
- 💡When an option mentions withdrawal or support, check that it is presented as a safeguard against harm rather than as a separate issue
- 💡Name the specific risk in the scenario, such as privacy or status, before describing the safeguard
- 💡Link each safeguard to the harm it reduces so the application is explicit
- 💡Use the wording of the ethical issue in your answer to show you are addressing the named risks
- 💡Check all three elements, informed, competent and voluntary, when judging whether consent is valid
- 💡Apply the elements to the scenario rather than listing them in isolation
- 💡Explain how a specific procedure, such as deception, affects validity and what the researcher does about it
- 💡Read the scenario for who the participants are and name the specific vulnerability before choosing an answer
- 💡Reject options that remove the right to withdraw or that rely on consent alone for children
- 💡Prefer the option that both protects participants and preserves the study's aim where possible
- 💡Identify the species and the procedure, then select the option that best reduces suffering without losing the aim
- 💡Reject options that increase animal numbers or remove welfare monitoring
- 💡Prefer answers that combine refinement of procedure with appropriate housing and handling
- 💡Read the scenario carefully and identify the specific risk before choosing a safeguard.
- 💡Reject options that describe a safeguard unrelated to the risk described in the stem.
- 💡Check whether an option confuses the role of an ethics committee with that of the researcher.
- 💡Always link ethical issues to the specific study scenario. Generic answers that list guidelines without application will not gain full marks. Use the 'issue - consequence - solution' structure.
- 💡When evaluating ethical costs and benefits, avoid absolute statements. Instead, use a balanced approach, considering both the scientific benefits and the ethical costs, and suggest how issues could be resolved.
- 💡Reference the BPS Code of Ethics and Conduct or relevant legislation (e.g., Data Protection Act) to demonstrate deeper understanding and secure top-band marks.
Common Mistakes
- Treats confidentiality and anonymity as identical; distinguish protected identifiable data from data that cannot be linked to a person
- Assumes confidentiality is absolute; recognise the limited circumstances in which disclosure may be justified
- Ignores small-sample identification; note that reporting group data can still reveal individuals in a small sample
- Overlooks the need to inform participants of limits to confidentiality; include prior disclosure of any exceptions
- Confuses deception with lack of informed consent; treat them as related but distinct issues, since consent concerns what participants agree to and deception concerns what they are told
- Assumes any withholding of information is unacceptable; recognise that justified, minimal deception with debriefing may be permitted by an ethics committee
- Overlooks the role of debriefing; include full debriefing as the standard safeguard after deception
- Treats deception as automatically invalidating a study; weigh the benefit to validity against the ethical cost
- Restricts the issue to physical pain only; include psychological harms such as stress, anxiety and humiliation
- Confuses this harm issue with deception; treat harm and deception as separate ethical issues even when they occur together
- Ignores the right to withdraw; include the option to withdraw and appropriate support as safeguards against harm
- Assumes any risk makes a study unethical; weigh the risk against the benefit and the steps taken to minimise it
- Treats psychological harm as only physical harm; recognise that values, beliefs, relationships, status and privacy are all named risks
- Assumes that informed consent removes all risk; note that sensitive procedures still need safeguards such as anonymity, the right to skip questions and debriefing
- Lists a safeguard without linking it to the specific risk it reduces; state which risk the safeguard addresses and how
- Treats any agreement as valid consent; check that the participant was informed, competent and free from pressure
- Assumes children can give valid consent alone; note that parental consent and the child's assent are usually required
- Ignores the effect of deception on consent; explain how limited information undermines validity and how debriefing or presumptive consent is used
- Treats a signed parental consent form as sufficient on its own; add the child's own assent and an ongoing right to withdraw
- Assumes vulnerability only means childhood; recognise other dependent or cognitively impaired groups and adjust safeguards
- Describes safeguards in the abstract without linking them to the specific study; apply each protection to the procedure described
- Lists the three Rs without applying them to the study; show how each principle changes the procedure described
- Assumes animal use is automatically unethical; weigh welfare safeguards against the stated scientific benefit
- Ignores species differences in housing and handling; match care to the species named in the scenario
- Treats ethics committees as a formality that always approves studies; explain that committees can require changes or reject proposals.
- Lists ethical guidelines without linking each one to the risk it reduces; match each safeguard to a named risk.
- Assumes informed consent alone removes all risk; note that ongoing monitoring and debriefing are also needed.
- Students often think that deception is always unethical and should never be used. In fact, deception can be justified if it is necessary for the study, does not cause harm, and participants are fully debriefed afterwards.
- Many students confuse ethical guidelines with ethical issues. Guidelines are the principles (e.g., informed consent), while issues are the problems that arise when guidelines are not met (e.g., lack of informed consent).
- Students sometimes believe that animals cannot be used in psychological research under any circumstances. However, animal research is permitted if it follows strict guidelines (e.g., the Animals (Scientific Procedures) Act 1986) and has clear scientific benefits.
Revision Plan
- 1Step 1: Learn the core ethical guidelines (informed consent, deception, protection from harm, confidentiality, privacy, right to withdraw) and the BPS principles. Create flashcards with definitions and examples.
- 2Step 2: Apply each guideline to at least two classic studies (e.g., Milgram, Zimbardo) and identify the ethical issues and how they were addressed. Practice writing 'issue - consequence - solution' paragraphs.
- 3Step 3: Practice cost-benefit analysis by evaluating the ethical costs and scientific benefits of a controversial study. Write a balanced evaluation paragraph.
- 4Step 4: Complete past exam questions on ethics, focusing on scenario-based questions. Mark your answers using the mark scheme and identify areas for improvement.
- 5Step 5: Review animal research ethics and the relevant legislation. Create a comparison table of human and animal ethical guidelines.
Exam Question Types
- 📋Scenario-based short answer questions (e.g., 'Identify two ethical issues in this study and suggest how each could be addressed'). Advice: Read the scenario carefully, name the issue, explain why it is an issue in context, and suggest a practical solution.
- 📋Extended writing questions (e.g., 'Discuss ethical issues in psychological research. Refer to examples in your answer.'). Advice: Structure your answer with an introduction, several paragraphs on different issues with examples, and a conclusion that weighs up costs and benefits.
- 📋Questions on animal research (e.g., 'Outline the ethical guidelines for using animals in psychological research.'). Advice: Know the Animals (Scientific Procedures) Act 1986 and the three Rs (replacement, reduction, refinement).
- 📋Evaluation questions (e.g., 'Evaluate the ethical costs and benefits of conducting research on obedience.'). Advice: Use a cost-benefit framework, consider both sides, and reach a justified conclusion.
Command Word Expectations (EDUQAS)
In Eduqas A-Level Psychology, 'identify' requires you to name or select the correct ethical issue or guideline from the scenario. No explanation is needed, but you must be precise. For example, 'lack of informed consent' rather than just 'consent'.
'Explain' requires you to give reasons or causes for something, showing your understanding. For example, explain why lack of informed consent is an ethical issue: because participants cannot make a fully informed decision about taking part, which undermines their autonomy.
'Discuss' requires a balanced consideration of different perspectives, including strengths and weaknesses, and a conclusion. For ethics, you should present ethical issues, ways of dealing with them, and evaluate the costs and benefits, using examples and referencing the BPS code.
'Evaluate' requires you to make a judgement about the value or importance of something, weighing up evidence and arguments. For ethics, you should assess the extent to which a study is ethical, considering both costs and benefits, and reach a justified conclusion.
How Students Lose Marks (Examiner Pitfalls)
Step-by-Step Worked Solutions
Question: A psychologist wants to investigate the effect of sleep deprivation on memory. Participants are asked to stay awake for 24 hours and then complete a memory test. They are not told the true aim of the study, and they are not allowed to withdraw once the study begins. Identify two ethical issues in this study and suggest how each could be addressed. (6 marks)
- 1.Step 1: Identify the ethical issues from the scenario: lack of informed consent (participants not told true aim) and lack of right to withdraw (not allowed to withdraw).
- 2.Step 2: Explain why each is an issue: informed consent is needed so participants can make an informed decision; right to withdraw protects participants from harm and respects autonomy.
- 3.Step 3: Suggest a way to address each: obtain informed consent by giving full information before the study, or use presumptive consent; allow participants to withdraw at any time and remind them of this right throughout.
Question: Explain how a researcher could deal with the ethical issue of deception in a study investigating conformity. (4 marks)
- 1.Step 1: Define deception: misleading participants about the true aim or procedures of the study.
- 2.Step 2: Identify a way to deal with deception: debriefing participants after the study, where the true aim is revealed and any misconceptions are corrected.
- 3.Step 3: Explain how debriefing addresses the issue: it restores participants' understanding, reduces potential harm, and allows them to withdraw their data if they wish.
- 4.Step 4: Mention an alternative: obtain prior general consent or presumptive consent, where participants agree to take part in research that may involve deception.
