Issues and Debates (Edexcel A-Level Psychology): Revision Notes
Overview of Issues and Debates in Social Psychology
Introduction
Social psychology research involves several important issues and debates that shape how we understand human social behaviour. These issues have been present throughout the development of social psychology and relate to ethics, methodology, and the application of psychological knowledge. Understanding these debates helps us critically evaluate social psychological research and its implications for society.
Ethics in social psychology research
Ethics refers to moral principles that govern research conduct, ensuring participants are protected from harm and treated with respect.
During the 1950s and 1960s, social psychologists conducted studies into prejudice and obedience that would be considered ethically and morally unacceptable by today's standards. Little experimental research has been conducted since, and no direct replications of these classic studies have been conducted without substantial modifications to address ethical concerns.
Ethical issues in obedience research
Obedience research carries inherent risks of causing psychological harm, which includes emotional distress, anxiety, or long-term psychological damage to participants. Research also raises concerns about the right to withdraw, as participants are gradually ordered to comply with requests to harm others. When participants are instructed to continue despite their protests, they may feel unable to exercise their right to leave the study.
The ethical issues in classic obedience research stem from two critical problems: participants experienced genuine psychological distress believing they were harming others, and the experimental pressure made it extremely difficult for them to exercise their right to withdraw from the study.
Ethical issues in prejudice research
Prejudice research creates the potential for psychological harm when groups are positioned against one another in situations designed to encourage conflict. Participants may experience distress from being placed in hostile intergroup situations or from being encouraged to display prejudiced attitudes.
Justification and criticism
Researchers may attempt to justify ethical problems by pointing to the important results their experiments achieved. However, achieving valuable results does not excuse the harm caused to participants. We must be aware of the specific ethical issues in this research area whilst also considering why these conditions were deemed necessary for studying obedience and prejudice in the first place.
The tension between scientific advancement and ethical treatment of participants remains a central debate in social psychology. While classic studies produced groundbreaking insights, they also established ethical boundaries that modern research must respect.
Practical issues in research design and implementation
Social psychology research faces several methodological challenges that affect the validity and reliability of findings.
Demand characteristics
Demand characteristics occur when participants become aware of the research aims and consequently fail to display natural behaviour. If participants understand what the study is investigating, they may alter their responses to align with what they believe the researcher expects.
Deception is often employed to prevent demand characteristics from occurring. Research into obedience and prejudice has used considerable effort to disguise the true aims of studies.
Worked Example: Milgram's Use of Deception
Consider Milgram's obedience research methodology and how it addressed demand characteristics:
- Recruitment deception - Participants were recruited under the pretence of a memory and learning experiment
- Role assignment - Employed a confederate actor and rigged a lottery for role assignment
- Equipment deception - Faked electrocution equipment and the confederate's responses to being shocked
- Reinforcing believability - Administered a sample shock to participants to reinforce the deception
This elaborate methodology ensured participants believed they were genuinely administering shocks to another person, thereby preventing them from guessing the study's true purpose.
Social desirability bias
Social desirability bias is the tendency for people to respond in ways that society deems more acceptable or which align better with social norms. This bias particularly affects attempts to measure prejudice in contemporary society, where prejudice has become more ambiguous, less obvious, and often too subtle to be detected by questionnaires.
Questionnaires that directly assess prejudiced beliefs can be criticised for failing to capture genuine prejudiced attitudes. People tend to mask their prejudices, particularly in today's social and cultural climate where overt discrimination is widely condemned.
Validity and reliability assessments
A range of validity and reliability assessments are necessary to ensure questionnaires accurately measure prejudice:
- Test-retest methods ensure the prejudice being measured remains consistent over time
- Split-half techniques assess the internal validity of the questionnaire in measuring prejudice
- Construct validity is validated using other measures, such as peer reports (Cohrs et al., 2012)
Correlations between different measures of prejudice and within questionnaires themselves often involve complicated analysis. However, these efforts have resulted in a series of robust questionnaires being created to accurately assess prejudiced attitudes (Fiske and North, 2014).
Modern prejudice measurement tools must overcome the challenge of social desirability bias while maintaining high standards of validity and reliability. This requires sophisticated assessment techniques and careful validation against multiple criteria.
Reductionism
Reductionism occurs when complex phenomena are explained by reducing them to simpler, more basic components or a single level of explanation.
Although social psychology aims to avoid reductionism, many theories can be criticised for focusing on specific data drawn from research to explain complex human social behaviours.
Reductionism in social impact theory
Social impact theory (Latané, 1981) can be criticised for being reductionist as it develops an equation to calculate how people will behave under certain social conditions. However, the theory does not account for how social conditions and individuals interact with one another. Ignoring the interrelation between individual and social factors can be considered reductionist.
Reductionism in dispositional explanations
Dispositional or personality explanations of prejudice and obedience can be considered reductionist as they focus solely on the character of the individual and disregard the social conditions in which prejudice and obedience are more likely to occur. Social psychologists such as Sherif rejected personality explanations, arguing that a multifaceted approach to understanding social influence was necessary.
A common pitfall in social psychology is explaining complex behaviours through a single lens. Both social impact theory's mathematical approach and purely dispositional explanations fail to capture the full complexity of human social behaviour by ignoring the interaction between individual characteristics and social contexts.
Comparisons between ways of explaining behaviour using different themes
Contrasting explanations of prejudice and obedience reveals their particular emphasis and subtle differences in approach.
Social identity theory vs realistic conflict theory
When comparing social identity theory and realistic conflict theory, both describe the role of groups in the formation of prejudice, using in-group favouritism (preference for one's own group) and negative out-group bias (prejudice against other groups).
The key difference lies in whether competition is necessary for prejudice to occur. Realistic conflict theory describes how competition between groups is a necessary condition for prejudice, whereas social identity theory does not require competition for prejudice to develop.
Understanding this distinction is crucial: realistic conflict theory suggests that removing competition would eliminate prejudice, while social identity theory argues that prejudice can arise simply from the psychological need to maintain a positive social identity, even without any tangible conflict.
Agency theory vs social impact theory
The differences between agency theory and social impact theory as explanations of obedience are more apparent. Social impact theory focuses strictly on the social conditions that encourage social influence, whilst agency theory accounts for the evolutionary basis of obedience, socialising factors, and psychodynamic forces that reduce the moral strain one experiences when displaying responsibility towards another person.
Historical shifts in explanations
Different approaches to explaining obedience and prejudice often reflect current social and historical events. Original attempts to explain social attitudes and behaviours tended to focus on dispositional causes, which reflected attitudes at the time that Germans during the Holocaust were somehow different from the rest of the world.
The emphasis has shifted towards more social explanations. Today, both dispositional and social theories are recognised as valid explanations, as social psychologists have become more aware of their interrelatedness.
Psychology as a science
Science involves systematic observation, experimentation, and the development of testable theories based on empirical evidence.
Social psychology in the early 19th century was concerned with understanding collective thinking and action. It was not until the writings of Floyd Allport (1924) that there was a clear call for social psychology to focus on experimentation and science.
The intention from this point was for social psychology to become more scientific and to focus on experimentation to understand group dynamics and behaviour. Norman Triplett is regarded as having conducted the first social psychology experiment on social facilitation at Indiana University in 1898, testing whether individuals performed better alone or when faced with competition from others.
The experimental tradition
This early influence paved the way for many social psychological experiments in the 1950s, 1960s, and 1970s, such as the Robber's Cave study by Sherif et al. (1961) and Milgram's research into obedience. In these experiments, variables could be controlled and carefully manipulated to ensure cause-and-effect relationships could be established under laboratory or more naturalistic conditions.
Criticisms of the scientific approach
Despite employing experimental methodology, social psychology can be criticised for studying human social behaviour in conditions that cannot be generalised to the real world. Group dynamics rarely exist in a social vacuum but are affected by social, historical, and cultural events which continually change. Any scientific approach taken to study human behaviour through experimentation should acknowledge this limitation.
According to Godow (1976), social psychology cannot be truly scientific because of the very subject it aims to explain: human social behaviour. Unlike the physical sciences, which investigate physical elements such as rocks and plants, social phenomena are affected by the mere presence of a researcher.
Humans change their behaviour to make themselves appear favourable or competent, and they bring with them attitudes and beliefs that affect how they behave. Variables such as social desirability bias, demand characteristics, researcher effects, and researcher bias all present challenges when investigating and recording human social behaviour.
This fundamental difference between social and natural sciences means that social psychology must develop its own standards of scientific rigour. While we can strive for objectivity, we must also acknowledge that studying human behaviour inherently involves subjective elements that physical sciences do not encounter.
Culture and gender
Social psychological research has investigated whether cultural and gender differences affect obedience and prejudice.
Gender and obedience
Gender stereotypes predict that women would be more compliant than males. However, experimental evidence from Milgram and other social psychologists has not found this to be the case. Social psychological theories of obedience, such as agency theory and social impact theory, explain obedience largely as a product of social circumstances and forces, which are not mediated by gender.
Although research into conformity (Crutchfield, 1955) found women to be more compliant than males, this has been argued to result from methodological bias. Male and female participants are exposed to male-orientated persuasion, which may account for greater female compliance. When exposed to female-orientated persuasion, males are more compliant.
The apparent gender differences in conformity research may reflect the research design rather than genuine psychological differences. This highlights the importance of considering potential biases in how we construct and interpret psychological studies.
Cross-cultural research on obedience
Milgram's obedience experiments have been conducted in many different cultures, most showing over 80% levels of obedience. One study that found very low levels of obedience (Kilham and Mann, 1974) was probably the product of methodological differences rather than genuine differences in obedience rates.
Collectivistic vs individualistic cultures
The distinction between collectivistic and individualistic cultures may be useful in understanding whether obedience is higher by culture. Typically, collectivistic cultures work together cooperatively and interdependently, so it could be predicted that higher levels of obedience and prejudice would be observed.
However, cross-cultural obedience research is not methodologically comparable, which may account for the differences in obedience rates found. Prejudice research has produced mixed findings regarding cultural differences. It is not yet clear whether culture is a mediating factor for either obedience or prejudice, probably because social and cultural conditions are not static. These ever-changing social circumstances affect whether a society is more prone to or resistant to authority, and whether social norms reinforce or challenge prejudice and discrimination.
Nature-nurture debate
The nature-nurture debate concerns whether behaviour is determined by innate biological factors (nature) or environmental and social influences (nurture).
The most important distinction in social psychological research is between whether behaviour is affected by dispositional causes (within the person) or situational factors (external to the person).
Dispositional explanations (nature)
Personality explanations of prejudice focus on the type of character that is more or less likely to be prejudiced, accounting for the nature side of the debate. Intergroup dynamic theories, such as realistic conflict and social identity theories, focus on the situational conditions that cause conflict, reflecting the nurture side of the debate.
Integration of nature and nurture
This may be an oversimplified distinction. In the case of personality theories, it is not necessarily true that nurture is ignored completely. Most personality accounts of prejudice explain that such traits arise from the way individuals are raised. Adorno, for example, explains that the authoritarian character develops from harsh parenting which leads to hostility directed at weaker targets.
The nature-nurture debate in social psychology is complex, with most contemporary theories acknowledging the interaction between dispositional and situational factors.
Modern social psychology has largely moved beyond the either/or nature-nurture dichotomy. Contemporary understanding recognises that most social behaviours result from complex interactions between biological predispositions and environmental influences, rather than being solely determined by one or the other.
Development of psychological knowledge over time
Social psychological knowledge has changed over time and is largely influenced by social changes in attitudes and historical events.
The classic research by Milgram, Sherif, and Zimbardo has been revisited, and group processes remain at the forefront of social psychological research. More recent developments in social psychology have attempted to investigate the underlying motivation and mental constructs associated with social influence research, bringing social psychology alongside cognitive psychology.
Historical influences on research
The Holocaust had a profound impact on early social psychology research, driving investigations into obedience and prejudice. As society has evolved, so too has the focus of social psychological research, moving from purely dispositional explanations to incorporating social and situational factors.
Contemporary developments
Modern social psychology increasingly integrates cognitive perspectives, examining how mental processes interact with social influences. This represents a shift from early research that focused primarily on observable behaviour to contemporary approaches that consider both internal cognitive processes and external social factors.
Issues of social control
Explanations and research in social psychology can be used for both beneficial and harmful purposes.
Negative applications of social control
Understanding what makes people obedient can be used to manipulate obedience. If we understand which conditions create the highest levels of obedience, this knowledge can be employed to ensure soldiers obey higher-ranking officers, or employees comply with their employers' requests.
Everyday Examples of Social Control
This can certainly be seen in everyday life:
- Police officers wear uniforms and have the ability to use punishment to keep behaviour in line with the law
- Majorities work against minorities to encourage conformity to social norms
- In the military, positions of authority are clearly identified by uniforms; supervising officers are immediately identifiable to their troops and have the authority to use sanctions to ensure obedience
Positive applications of social control
Social control can be positive. Research into the social conditions that cause prejudice has led to developments in reducing prejudice. The jigsaw technique (Aronson et al., 1978) is based on the Sherif et al. summer camp studies (1954, 1961), where superordinate goals were used to reduce prejudice.
Designing classroom and workplace environments that maximise the jigsaw technique can be used to control levels of intergroup hostility and reduce bullying and negative competition.
The dual nature of social psychological knowledge means researchers have an ethical responsibility to consider how their findings might be applied. Knowledge that can reduce prejudice can also potentially be misused to manipulate behaviour in harmful ways.
Use of psychological knowledge in society
The main application of prejudice research in society has been to reduce prejudice.
Educational applications
This knowledge has been used in classrooms (jigsaw technique and other structured learning environments) to reduce racial bias in multi-ethnic schools. Using our knowledge of stereotypes, we can educate people to be more mindful of the similarities that exist between different groups rather than focusing on differences.
Langer et al. (1985) found an improvement in how children perceived disability when encouraged to be more mindful; this intervention reduced stereotypes and increased empathy.
Equal status contact
Intergroup hostility is facilitated by a lack of equal status contact. This explains why communities divided by physical barriers or educational and employment integration often experience conflict. This was the case in Northern Ireland, where land was divided into Protestant and Catholic areas and integration was not permitted.
Research Application: The Deutsch and Collins Housing Study (1951)
In 1951, Deutsch and Collins took advantage of a desegregation housing project in New York to conduct a social psychological investigation into equal status contact.
Research Design: Using social identity theory as a basis for their research, they predicted that desegregation would reduce negative out-group bias and intergroup conflict between whites and blacks.
The Study: In accordance with New York State law, two public housing projects were designed to allocate housing regardless of race. They compared these housing projects to two similar projects in New Jersey where whites and blacks were segregated into different blocks. In the desegregated housing blocks, housewives mixed regularly when doing their laundry, meeting in the street, and at the grocers.
Findings: Asking a random sample of white housewives, they found that white housewives in desegregated housing held black housewives in higher regard and were more in favour of interracial housing compared to the segregated housewives, who held stereotypes of blacks being dangerous and inferior.
Impact: This demonstrated the effectiveness of equal status contact for reducing prejudice, a lesson that was applied to other public housing projects.
In a meta-analysis of over 515 intergroup contact studies, Pettigrew and Tropp (2006) found that contact does reduce prejudice, providing empirical support for the equal status contact hypothesis.
Issues related to socially sensitive research
Socially sensitive research refers to studies that have potential social consequences for the participants themselves or the groups they represent.
Any research into prejudice and discrimination has the potential to be socially sensitive for the participants involved in the research or the groups which they represent.
Historical examples of bias
Very early social research into prejudice can be heavily criticised for exaggerating differences between races and producing biased evidence that whites were superior to blacks. Whilst this opinion is not held today, at the time this psychological knowledge legitimised social, educational, and economic divisions between races and endorsed discriminatory practices and legislation.
Contemporary concerns
Modern research must be carefully designed to avoid perpetuating stereotypes or causing harm to particular groups. Researchers must consider:
- The potential impact of their findings on different social groups
- How research might be misinterpreted or misused
- The ethical responsibility to present findings in a balanced, non-discriminatory way
- The need for culturally sensitive research methods and interpretations
Socially sensitive research requires researchers to carefully balance scientific inquiry with ethical responsibility. The potential for research findings to be misused or to perpetuate stereotypes means that social psychologists must be particularly thoughtful about how they design studies, interpret results, and communicate their findings to the public.
Remember!
Key Points to Remember:
-
Ethics in social psychology raise concerns about psychological harm, deception, and the right to withdraw, particularly in classic obedience and prejudice research.
-
Demand characteristics and social desirability bias are major methodological challenges that researchers must address through careful study design and validation procedures.
-
Reductionism occurs when complex social behaviours are oversimplified; both social impact theory and dispositional explanations can be criticised for being reductionist.
-
Psychology as a science faces unique challenges because human behaviour is affected by the research process itself, unlike physical sciences.
-
Cultural and gender factors have complex relationships with obedience and prejudice that are not yet fully understood, partly due to methodological differences across studies.
-
The nature-nurture debate is central to social psychology, with modern approaches recognising the interaction between dispositional and situational factors.
-
Social control can be applied positively (reducing prejudice through techniques like the jigsaw classroom) or negatively (manipulating obedience in hierarchical structures).
-
Socially sensitive research requires careful consideration of how findings might impact the groups being studied and how results might be misinterpreted or misused.
