Issues and Debates (Edexcel A-Level Psychology): Revision Notes
Issues and Debates
Introduction to issues and debates
Issues and debates represent philosophical, methodological, and ethical considerations that are relevant across all areas of psychology. These concepts apply to different approaches, explanations, and research studies within the discipline. When studying psychology, you need to consider how issues and debates relate to:
- Classic research studies you have examined
- Theories and concepts across all topics
- Applications of psychological knowledge
Understanding issues and debates requires synthesising knowledge from different areas of your course. For example, you might compare how the cognitive and learning approaches address the nature-nurture debate, or evaluate different studies based on their scientific status.
Ethical issues involved in research in psychology
The debate around deception
A common statement in psychology suggests:
"Psychological research is often held back because researchers cannot study human behaviour in a way that is meaningful without violating ethical principles relating to deception."
This statement raises important questions about the balance between conducting meaningful research and maintaining ethical standards. To evaluate such a claim, you need to consider:
- The purpose and function of the ethical principle being discussed
- What constitutes deception and why researchers use it
- The consequences of using deception for participants
- Whether meaningful research can proceed without deception when guidelines are followed
Understanding deception in research
Deception occurs when researchers provide misleading or incomplete information to participants about the true nature, aims, or procedures of an investigation. This gives participants false information or withholds important details that might influence their decision to participate.
Ethical guidelines and principles exist to ensure meaningful research can proceed whilst protecting participants and the groups they represent. However, some researchers argue that these guidelines restrict both the topics that can be investigated and the methods available for investigation.
The principle of informed consent
Deception directly relates to the principle of informed consent. This principle states that participants must have the capacity to give informed consent before taking part in research. If a participant has been deceived about the nature of an investigation, they cannot provide genuine informed consent.
Under ethical guidelines, when individuals cannot provide informed consent themselves, representatives, peers, or colleagues should be informed and consulted. In such cases, research may need to be restricted to ensure participants are not harmed by their participation.
The British Psychological Society (BPS) guidelines state that deception should be avoided unless it threatens the integrity of the research and can be resolved by informing participants at the earliest opportunity.
Why researchers use deception
Deception serves as a methodological tool in psychological research for several reasons:
Preventing demand characteristics: Participants may alter their behaviour or responses if they are fully aware of the true aims of an investigation. This threat to validity means deception helps avoid suspicion, prevent demand characteristics, and ensure natural behaviour.
Worked Example: Milgram's Obedience Study
Milgram deliberately misled participants about the aims of his investigation and its procedure. Had participants known the study examined obedience, they might not have reacted naturally.
Key deception elements:
- Participants believed they were administering real electric shocks
- The true aim (studying obedience) was concealed
- The "learner" was actually a confederate
Why it was necessary: If participants had been aware the learner was not receiving real shocks, they would not have experienced stress or responded to authority in the observed manner. Thus, Milgram used deception to protect the integrity of his experiment.
Eliciting true responses: Research into aggression poses particular issues related to deception. If participants know a researcher is examining aggression in certain situations, they may refrain from engaging in aggressive behaviour because it is not deemed socially desirable. Similarly, questionnaires designed to elicit true responses may need to disguise their objectives, otherwise participants will be mindful of how their responses appear to others and may offer disingenuous answers.
Applications of deception in research
Criminological psychology: Research using deception has provided important benefits for legal policy and practice. Mock jury studies that manipulate variables such as the attractiveness, race, or accent of a defendant without participants knowing this is under investigation have contributed to understanding jury bias.
Clinical psychology: Research involving participants being allocated to a placebo condition without their knowledge has advanced understanding of the placebo effect and the actual effectiveness of treatments, using the placebo as a baseline condition.
Consequences of deception for participants
The consequences of deception can be problematic for psychological researchers and affect the reliability of findings. The impact on participants may include:
- Embarrassment
- Mistrust of psychological research
- Anxiety
The extent to which participants experience these feelings depends largely on:
- How and why they have been deceived
- How the researcher reconciles the nature of the deception with participants following the investigation
Impact on autonomy: Deception intentionally removes self-determination and autonomy from individual participants, which violates ethical principles. The overuse of deception can:
- Create suspicion about psychological research that discourages participation
- Encourage participants to second-guess researchers
- Bring the subject into disrepute
The debate: should deception be used?
Arguments supporting the use of deception:
The extent to which deception should be used to ensure meaningful research leads to debate. Most researchers argue deception is a methodological and ethical 'double-edged sword' because it can:
- Ensure the reliability and validity of findings
- Violate ethical principles when used
However, when used appropriately, deception can:
- Maintain the integrity of research
- Maintain the autonomy of participants
- Prevent harm to participants
Much research in psychology involves deception, but this does not necessarily mean harm is caused. Not all deception causes distress or embarrassment; indeed, some participants can benefit from the psychological insight into their own behavioural patterns gained through research involvement.
Arguments against the use of deception:
Many researchers argue that deception is unjustifiable and steps should be taken to inform participants that they could be subject to deception or to involve third parties to gain presumptive consent.
Key issues associated with deception:
- Whether participant autonomy is affected
- Whether deception causes harm
To withhold or falsely misrepresent the intentions or procedure of a study means a participant's capacity to give informed consent is impaired.
Milgram's experiment as a case study: The use of deception in Milgram's experiment is commonly cited as research that contravenes ethical guidelines. The use of deception caused considerable harm to participants and diminished their capacity to exercise informed consent.
The question remains debated as to whether the deception actually caused harm. Some argue the harm was momentary and no greater than being placed in an uncomfortable situation. Others believe participants understood and accepted the nature of the experimental deception and that it was necessary to achieve important psychological insights into obedience to authority.
Rather than limiting personal autonomy, knowledge of natural reactions under such conditions could have provided a self-reflection exercise for participants that might promote autonomy in the future. Knowledge that they were blindly obedient could prevent blind obedience in future situations.
Synoptic application
When using your knowledge of ethics synoptically by drawing on relevant psychological research from across approaches and applications, you should consider how issues and debates must be applied across different areas.
Take a theme from each issue and debate and apply it to as many approaches, explanations, and studies that are relevant. This allows you to demonstrate comprehensive understanding across different theories in psychology and how they can be used to explain real-life situations.
Remember!
Key Points to Remember:
-
Issues and debates are philosophical, methodological, and ethical concepts that apply across all of psychology, not just to individual studies or approaches.
-
Deception is used as a methodological tool to prevent demand characteristics and ensure natural behaviour, but it raises ethical concerns about informed consent and participant autonomy.
-
The use of deception involves a balance: it can ensure reliable and valid findings whilst potentially violating ethical principles relating to informed consent and causing harm to participants.
-
Ethical guidelines (such as those from the BPS) state that deception should be avoided unless it is necessary to maintain research integrity and participants are debriefed at the earliest opportunity.
-
The debate around deception demonstrates the need for careful judgement in research design, weighing the benefits of meaningful research against potential harm to participants.
