AQA GCSE Psychology: Social Influence and Language, Thought and Communication Revision Guide

Social Influence and Language, Thought and Communication are two of the four topics examined on Paper 2 of AQA GCSE Psychology (8182). Together they make up a substantial portion of the paper, and both require you to know key studies in detail, understand the theories behind everyday social behaviour, and evaluate evidence critically. Students who treat these topics as simple common sense tend to struggle -- the exam rewards precise terminology, specific study details, and structured evaluation, not general observations about how people behave.

This guide covers everything you need to know for both topics, including the key studies, theories, and evaluation points that the AQA specification demands. Whether you are starting your revision or doing a final review before the exam, use this as a checklist to make sure nothing has been missed.

How These Topics Are Assessed

AQA GCSE Psychology is assessed through two written exams, each worth 50% of your final grade.

Paper 1: Cognition and Behaviour

• 1 hour 45 minutes
• 100 marks (50%)
• Topics: Memory, Perception, Development, Research Methods

Paper 2: Social Context and Behaviour

• 1 hour 45 minutes
• 100 marks (50%)
• Topics: Social Influence, Language Thought and Communication, Brain and Neuropsychology, Psychological Problems

Social Influence and Language, Thought and Communication are both examined on Paper 2. You will face a mixture of multiple-choice questions, short-answer questions, and extended-response questions worth up to 6 marks. Application questions are common -- you may be given a scenario and asked to use your knowledge of conformity, obedience, or language and thought to explain what is happening. Research methods questions can also appear in these sections, so be prepared to identify variables, evaluate methodology, and discuss ethical issues within the context of social influence and communication studies.

Social Influence

Conformity

Conformity is a change in a person's behaviour or opinions as a result of real or imagined pressure from a person or group. It is important to understand the three types of conformity, as the exam may ask you to identify or distinguish between them.

Compliance is the shallowest level of conformity. The individual goes along with the group publicly but does not change their private opinion. This is often driven by normative social influence -- the desire to fit in and be accepted by others. As soon as the group pressure is removed, the person reverts to their original view.

Identification occurs when a person conforms to the expectations of a social role or group they value. The individual adopts the group's views publicly and may partially accept them privately, but only while they remain a member of that group. The behaviour changes if the person leaves the group or the role ends.

Internalisation is the deepest level of conformity. The individual genuinely accepts the group's views and incorporates them into their own belief system. This often results from informational social influence -- when a person looks to others for guidance because they are unsure of the correct answer. The change in belief persists even when the group is no longer present.

Factors affecting conformity include group size, unanimity, and task difficulty. Research shows that conformity increases as group size grows, but only up to a point -- adding more people beyond around three to four members has a diminishing effect. Unanimity is critical: if even one person in the group disagrees with the majority, conformity rates drop sharply. Task difficulty also matters -- people are more likely to conform when the task is ambiguous or they are unsure of the correct answer, because they rely on informational social influence.

Asch's Line Study (1951)

Solomon Asch conducted one of the most well-known studies on conformity. In his procedure, a naive participant was placed in a group with between six and eight confederates. The group was shown a series of lines and asked to match a target line to one of three comparison lines. The correct answer was always obvious. On 12 of the 18 trials (the critical trials), the confederates had been instructed to give the same incorrect answer unanimously before the naive participant responded.

Key findings:

• On the critical trials, the average conformity rate was 37% -- meaning participants gave the wrong answer in line with the confederates 37% of the time.
• 75% of participants conformed at least once during the experiment.
• 25% of participants never conformed on any critical trial.

Asch also ran several variations of the study. When one confederate gave the correct answer (breaking unanimity), conformity dropped significantly. When the task was made harder by making the lines closer in length, conformity increased. When participants could write their answers privately rather than stating them aloud, conformity dropped sharply.

Strengths of Asch's study:

• The study used a controlled laboratory procedure, which means extraneous variables could be minimised and the study could be replicated to check reliability.
• The variations demonstrated clearly that specific factors -- such as unanimity and task difficulty -- affect conformity, providing strong evidence for understanding the conditions under which people conform.

Limitations of Asch's study:

• The task was artificial. Judging line lengths is not something people do in everyday life, so the study may lack ecological validity. Real-world conformity may operate differently when the stakes are higher or the situation is more personally meaningful.
• The sample consisted of male American college students, which limits the generalisability of the findings to other populations, cultures, and genders.
• The study was conducted in the 1950s during a period of strong social conformity in the United States. Replications in other time periods have found lower conformity rates, suggesting the findings may be historically specific.

Obedience

Obedience is a form of social influence where a person follows a direct order or instruction from an authority figure. It differs from conformity in several important ways: obedience involves a clear hierarchy between the person giving the order and the person carrying it out, whereas conformity involves pressure from equals. Obedience is a response to a direct instruction, while conformity is a response to implicit group pressure. In obedience, the person knows they are being told what to do; in conformity, the person may not even realise they are adjusting their behaviour.

Milgram's Obedience Study (1963)

Stanley Milgram designed an experiment to investigate how far people would go in obeying an authority figure, even when the instructions involved harming another person. Forty male volunteers were recruited through newspaper advertisements and were told the study was about the effects of punishment on learning.

In the procedure, each participant was assigned the role of "teacher" (this was rigged), while a confederate played the "learner." The learner was strapped to a chair in another room and connected to what appeared to be an electric shock generator. The teacher was told to administer an electric shock each time the learner gave a wrong answer to a word-pair task, increasing the voltage by 15 volts with each wrong answer, from 15V up to 450V. The shocks were not real, but the participant believed they were. The learner gave predetermined wrong answers and, as the voltage increased, began to express pain, demand to be released, and eventually fell silent. An experimenter in a lab coat prompted the teacher to continue with a series of verbal prods such as "The experiment requires that you continue."

Key findings:

• 65% of participants administered the maximum 450-volt shock.
• All participants went to at least 300 volts.
• Many participants showed signs of extreme distress, including sweating, trembling, and nervous laughter, yet continued to obey.

Variations of Milgram's study:

Milgram conducted several variations to investigate which factors influenced obedience levels:

• Proximity: When the learner was in the same room as the teacher, obedience dropped to 40%. When the teacher had to physically place the learner's hand on a shock plate, it dropped further to 30%. Greater physical proximity to the victim reduced obedience.
• Location: When the experiment was moved from the prestigious Yale University to a run-down office building, obedience dropped to 47.5%. The perceived legitimacy of the setting affected willingness to obey.
• Uniform: When the experimenter left the room and gave instructions by telephone, obedience dropped to 20.5%. When an ordinary member of the public gave the orders instead of a man in a lab coat, obedience also dropped significantly. The authority figure's perceived legitimacy, signalled partly by their uniform and role, was important.

Explanations for obedience:

• Agency theory proposes that people operate in two states. In the autonomous state, individuals see themselves as responsible for their own actions. In the agentic state, they see themselves as agents carrying out the wishes of an authority figure and shift responsibility for their actions onto that authority. Milgram argued that participants entered the agentic state during the experiment, which allowed them to continue administering shocks because they no longer felt personally responsible.
• Authoritarian personality is a dispositional explanation. Adorno suggested that people with an authoritarian personality are more likely to obey authority figures. These individuals tend to be rigid in their thinking, conventional, and hostile toward those of lower status, while being submissive toward those of higher status. This personality type is thought to develop through strict, punitive parenting.
• Situational factors also explain obedience. The variations of Milgram's study show that obedience is not simply a trait within the individual -- it is heavily influenced by the situation. Factors such as the proximity of the victim, the location of the experiment, the presence and authority of the experimenter, and the gradual escalation of demands all contributed to obedience levels.

Strengths of Milgram's study:

• The study produced quantitative data (percentage obeying to each voltage level), which is objective and allows comparisons across variations.
• The variations systematically changed one factor at a time, allowing cause-and-effect conclusions about which situational factors affect obedience.

Limitations of Milgram's study:

• There are serious ethical concerns. Participants were deceived about the true purpose of the study and the fact that the shocks were fake. Many experienced significant psychological distress during the procedure, raising questions about whether their wellbeing was adequately protected.
• The ecological validity of the study has been questioned. Administering electric shocks in a laboratory is not representative of real-world obedience situations, so it is unclear whether the findings apply to everyday life.
• Demand characteristics may have influenced the results. Some critics, including Orne and Holland, have argued that participants may not have genuinely believed the shocks were real, which would undermine the validity of the findings as evidence of true obedience.
• The sample of 40 male American volunteers limits the generalisability of the findings to women and other cultures.

Prosocial Behaviour

Prosocial behaviour refers to actions that benefit others, such as helping, sharing, or cooperating. An important concept in this area is the bystander effect -- the finding that individuals are less likely to help a person in need when other people are present.

Diffusion of responsibility is the key explanation for the bystander effect. When multiple bystanders are present, each individual feels less personal responsibility to intervene because they assume someone else will act. The more bystanders there are, the less responsible each person feels, and the less likely any single person is to help.

Piliavin's subway study (1969) investigated bystander behaviour in a real-world setting. A confederate collapsed on a New York subway train, either appearing to be drunk (carrying a bottle and smelling of alcohol) or appearing to be ill (carrying a walking cane). The researchers observed how quickly other passengers helped and how many helped.

The findings showed that the "ill" victim received help much more quickly and more frequently than the "drunk" victim. Help was offered on 95% of trials for the cane condition but far less often in the drunk condition. The study also found that bystander intervention was not always reduced by the presence of others -- in the confined space of a subway carriage, people were more likely to help, which challenges the simple diffusion of responsibility explanation.

A strength of Piliavin's study is its high ecological validity -- it took place in a natural setting with real bystanders who did not know they were being observed, so the behaviour was genuine. A limitation is that the participants could not give informed consent, raising ethical concerns about the right to privacy and the potential for distress.

Crowd and Collective Behaviour

Deindividuation is the process by which individuals lose their sense of personal identity and responsibility when part of a crowd. This can lead to behaviour that the individual would not normally engage in, including antisocial behaviour. Anonymity, being in a large group, and arousal all contribute to deindividuation.

Le Bon's crowd theory was one of the earliest explanations of crowd behaviour. Le Bon proposed that individuals in a crowd develop a "group mind" -- they become anonymous, suggestible, and contagious in their emotions and actions. He argued that crowds bring out primitive, irrational behaviour because the individual's personal restraints are weakened. While influential, Le Bon's theory has been criticised for being overly negative about crowd behaviour and for lacking empirical evidence.

Social identity theory offers an alternative explanation for collective behaviour. Rather than crowds producing irrational behaviour, social identity theory proposes that people in crowds behave according to the norms of the social group they identify with. When people identify strongly with a group, they adopt the group's norms and values, and their behaviour reflects those shared standards. This means crowd behaviour can be prosocial or antisocial depending on the group's identity and norms, which is a more nuanced view than Le Bon's theory provides.

Language, Thought and Communication

The Relationship Between Language and Thought

One of the central questions in this topic is the relationship between language and thought. Do we think in language, or does thought exist independently of the words we use? Two major positions provide contrasting answers.

Piaget: Language Depends on Thought

Jean Piaget argued that cognitive development drives language development -- in other words, thought comes first, and language follows. According to Piaget, children must first understand a concept before they can express it in words. For example, a child must develop the concept of object permanence before they can meaningfully talk about objects that are out of sight. Language, in this view, is a tool for expressing thoughts that already exist rather than a mechanism that shapes those thoughts.

Evidence supporting Piaget's position includes the observation that children across very different language backgrounds reach the same cognitive milestones in the same order, which suggests that cognitive development follows a universal pattern that is not determined by the language the child speaks.

The Sapir-Whorf Hypothesis

Benjamin Lee Whorf, building on the ideas of Edward Sapir, proposed that language shapes thought. This hypothesis exists in two versions.

The weak version -- linguistic relativity -- suggests that language influences the way we think and perceive the world. Different languages encourage different ways of thinking, but they do not prevent speakers from understanding concepts that their language does not easily express. For example, a language with many words for different types of snow may make its speakers faster at distinguishing between types of snow, but speakers of other languages can still learn to make those distinctions.

The strong version -- linguistic determinism -- goes further and proposes that language determines thought. According to this view, if a language lacks a word or structure for a concept, its speakers cannot think about that concept at all. This is a much more extreme claim and has less empirical support.

Evidence for the Sapir-Whorf hypothesis:

• Research on colour perception has shown that speakers of languages with more colour terms can distinguish between colours more quickly than speakers of languages with fewer colour terms. For example, speakers of Russian, which has separate basic words for light blue and dark blue, are faster at distinguishing between these shades than English speakers.
• The Hopi people of North America have a very different way of expressing time in their language compared to English. Whorf argued that this meant they thought about time differently, supporting the idea that language shapes thought.

Evidence against the Sapir-Whorf hypothesis:

• Even where languages lack specific words for concepts, speakers can still understand and learn those concepts when they are explained, which challenges the strong version of the hypothesis.
• Piaget's evidence that cognitive development follows a universal sequence regardless of the language spoken suggests that fundamental thought processes are not determined by language.
• The strong version is very difficult to test because it is hard to separate the effects of language from the effects of culture -- people who speak different languages often also live in different cultural environments.

Differences Between Human and Animal Communication

While both humans and animals communicate, human language has several unique properties that distinguish it from animal communication systems.

Productivity (also called creativity) refers to the ability to combine a finite set of words and rules to produce an infinite number of novel sentences. Humans can create and understand sentences they have never heard before. Animal communication systems, by contrast, are typically limited to a fixed set of signals with fixed meanings.

Displacement is the ability to communicate about things that are not present in the immediate environment -- events in the past, plans for the future, or hypothetical situations. While some animal communication shows limited displacement (for example, the waggle dance of honeybees communicates the location of distant food sources), humans can talk about abstract concepts, imaginary events, and distant times and places in far more complex ways.

Cultural transmission means that human language is passed down from one generation to the next through learning rather than being entirely innate. Children learn the specific language of their community by being exposed to it. While some animal communication has an innate component, human language is largely culturally acquired, which is why there are thousands of different human languages around the world.

Non-Verbal Communication

Non-verbal communication (NVC) refers to the messages we send without using words. It plays a crucial role in how we interact with others and can reinforce, contradict, or replace verbal messages.

Eye contact serves multiple functions in communication. It can signal interest, attention, or attraction. Maintaining eye contact can indicate confidence or honesty, while avoiding eye contact may suggest discomfort, deception, or submission. The appropriate amount of eye contact varies across cultures.

Body language includes gestures, posture, and movement. Open body language (such as uncrossed arms and leaning forward) tends to communicate receptiveness and engagement, while closed body language (crossed arms, turning away) can signal defensiveness or disinterest.

Facial expressions are a key channel for communicating emotions. Research by Paul Ekman has suggested that certain basic facial expressions -- such as those for happiness, sadness, anger, fear, surprise, and disgust -- are universal across cultures, which supports the idea that some aspects of non-verbal communication are innate rather than learned.

Personal space refers to the physical distance people maintain between themselves and others. Edward Hall identified four zones: intimate distance (up to about 45 cm), personal distance (45 cm to 1.2 m), social distance (1.2 m to 3.6 m), and public distance (over 3.6 m). The appropriate distance depends on the relationship between the people involved and varies across cultures.

Touch communicates a wide range of messages depending on the context, from comfort and affection to dominance and aggression. The meaning of touch is heavily influenced by the relationship between the people involved and the cultural setting.

Tone of voice (also called paralinguistics) includes pitch, volume, speed, and intonation. The same words can carry very different meanings depending on how they are spoken. Sarcasm, for instance, relies heavily on tone of voice rather than the literal meaning of the words.

Key Study: Yuki (2007)

Research into cultural differences in interpreting non-verbal communication provides useful evidence for this topic. Yuki (2007) found that Japanese participants focused more on the eyes when interpreting facial expressions on emoticons, while American participants focused more on the mouth. This supports the idea that non-verbal communication is influenced by culture and that people from different cultural backgrounds may interpret the same non-verbal signals differently. This study is relevant to both NVC and the broader question of how culture shapes communication.

How These Topics Are Assessed on Paper 2

On Paper 2, questions on Social Influence and Language, Thought and Communication can range from 1-mark multiple-choice items to 6-mark extended-response questions. Be prepared for:

• AO1 (Knowledge and Understanding): Questions asking you to describe theories, studies, or concepts -- for example, "Describe Milgram's study of obedience" or "Outline the Sapir-Whorf hypothesis."
• AO2 (Application): Scenario-based questions where you must apply your knowledge to a situation -- for example, being given a scenario about someone following a crowd and being asked to explain their behaviour using concepts of conformity.
• AO3 (Evaluation): Questions asking you to evaluate a study or theory -- for example, "Evaluate Asch's research into conformity" or "Discuss one strength and one limitation of Piliavin's subway study."

For 6-mark extended-response questions, you will need to combine knowledge, application, and evaluation. Structure your answer clearly: describe the relevant theory or study, apply it to the question or scenario, and evaluate it with at least one or two well-developed points.

Research methods questions may also appear in these sections. You could be asked to identify the independent or dependent variable in a social influence experiment, suggest improvements to a study's methodology, or discuss ethical issues raised by research into obedience or conformity.
