Language, Thought and Communication

What you'll learn

This topic examines the relationship between the words we use, the thoughts we have, and how we communicate with others. You'll explore how language shapes our thinking, the differences between human and animal communication, and the importance of both verbal and non-verbal communication in everyday interactions. This material is directly assessed in OCR GCSE Psychology Component 2.

Key terms and definitions

Piaget's theory — the view that language depends on thought; children must first understand a concept before they can use the words to describe it.

Sapir-Whorf hypothesis — the theory that language determines or influences thought; the words available in a language shape how speakers think about the world.

Von Frisch's bee study — research demonstrating that honeybees communicate the location of food sources through a waggle dance, showing non-human communication can convey specific information.

Displacement — the ability to communicate about things not present in time or space; a unique feature of human language.

Non-verbal communication (NVC) — transmission of messages without words, including body language, facial expressions, eye contact, gestures, posture and tone of voice.

Eye contact — direct visual connection between people; serves functions including regulating conversation flow, expressing emotion, and establishing relationships.

Personal space — the physical distance people maintain between themselves and others, which varies by culture, relationship and context.

Open and closed posture — body positioning that either invites interaction (open: uncrossed limbs, facing toward) or signals defensiveness or disinterest (closed: crossed arms/legs, turned away).

Core concepts

The relationship between language and thought

Two major theories explain how language and thought interact:

Piaget's theory: thought before language

Jean Piaget argued that cognitive development drives language acquisition. Key principles include:

• Children develop mental schemas (frameworks for understanding) through interaction with their environment
• Language emerges only after children grasp the underlying concept
• Evidence: children worldwide develop object permanence (understanding objects exist when out of sight) before using words for hidden objects
• Supports: the pre-linguistic stage where infants think and problem-solve without language

The Sapir-Whorf hypothesis: language shapes thought

Benjamin Lee Whorf and Edward Sapir proposed that language influences or determines thought patterns:

• Strong version (linguistic determinism): language completely determines thought; you cannot think about concepts without words for them
• Weak version (linguistic relativity): language influences thought but doesn't completely control it
• Evidence: Inuit languages have multiple words for snow, potentially making speakers more aware of snow variations
• Counter-evidence: people can imagine colours they don't have specific words for

Evaluation of both theories

Strengths of Piaget's approach:

• Explains why children understand concepts before accurately verbalising them
• Supported by cross-cultural research showing similar cognitive developmental stages

Weaknesses of Piaget's approach:

• Underestimates how language might help organise and refine thought
• Cannot fully explain why bilingual speakers sometimes think differently in each language

Strengths of Sapir-Whorf:

• Explains cultural differences in perception and categorisation
• Supported by studies showing language affects colour perception and spatial reasoning

Weaknesses of Sapir-Whorf:

• Strong version lacks empirical support; people can understand concepts without specific vocabulary
• Difficult to separate language effects from broader cultural influences

Differences between human and animal communication

Human language possesses unique characteristics that distinguish it from animal communication systems.

Characteristics of human language

• Displacement: humans can discuss past events, future plans, and hypothetical situations
• Productivity/creativity: infinite novel sentences can be created from finite grammatical rules
• Structure: systematic grammar with rules for combining sounds (phonology), words (syntax) and meaning (semantics)
• Cultural transmission: language is learned socially, not purely instinctive
• Semanticity: symbols (words) represent specific meanings

Animal communication

Animals communicate but generally lack the complexity of human language:

• Often limited to present circumstances (food, danger, mating)
• Fixed repertoire of signals rather than creative combinations
• Largely instinctive rather than culturally learned
• Can be sophisticated but typically lacks grammatical structure

Von Frisch's bee study (1967)

Karl von Frisch investigated honeybee communication:

• Procedure: Observed bees returning to hive after finding food sources at varying distances and directions
• Findings: Bees perform "waggle dances" encoding information about food location
  • Round dance: food source nearby (within 100 metres)
  • Waggle dance: food source distant; angle of dance indicates direction relative to sun; duration indicates distance
• Conclusion: Bees can communicate specific, detailed information through non-verbal signals

Evaluation of Von Frisch's study

Strengths:

• Systematic observation over many years
• Demonstrated that non-human communication can be referential (about external objects)
• High ecological validity (natural bee behaviour)

Weaknesses:

• Bee communication still lacks displacement (only about current food sources)
• Limited flexibility compared to human language
• Cannot generalise findings to all animal species

Non-verbal communication in humans

Non-verbal communication (NVC) often conveys more meaning than spoken words, particularly regarding emotions and attitudes.

Functions of non-verbal communication

• Managing interactions: turn-taking in conversation, signalling agreement or confusion
• Expressing emotions: facial expressions, tone of voice convey feelings
• Conveying attitudes: body language shows interest, boredom, attraction or hostility
• Supporting verbal messages: gestures emphasise or illustrate speech
• Replacing words: thumbs up, head shake communicate without speech

Types of non-verbal communication

Eye contact (gaze)

• Regulates conversations: looking away signals you're still speaking; looking at listener signals turn-taking
• Expresses emotions: prolonged gaze can show interest or aggression; avoiding eye contact may suggest discomfort
• Establishes relationships: more eye contact typically occurs between friends than strangers
• Cultural variations: direct eye contact considered respectful in UK but disrespectful in some Asian cultures

Argyle and Dean's (1965) equilibrium theory

• Proposes people maintain comfortable intimacy levels by balancing eye contact, proximity and other NVC
• If one person moves physically closer, the other may reduce eye contact to maintain equilibrium
• Supported by research showing people look less when standing closer

Facial expressions

• Ekman and Friesen identified six universal expressions: happiness, sadness, fear, anger, surprise, disgust
• Recognised across cultures, suggesting biological basis
• Can be deliberately controlled (masking true feelings) or spontaneous

Body language

• Posture:
  • Open posture (uncrossed limbs, facing toward) signals receptiveness and honesty
  • Closed posture (crossed arms/legs, turned away) suggests defensiveness or disinterest
• Gestures: hand movements that illustrate (showing size), regulate (beckoning), or symbolise (waving goodbye)
• Touch: handshakes, pats on back convey friendship, support or status

Personal space

Edward Hall (1966) identified four distance zones used in Western cultures:

• Intimate distance (0-45cm): close family, romantic partners
• Personal distance (45cm-1.2m): friends and acquaintances
• Social distance (1.2-3.6m): impersonal business, formal interactions
• Public distance (3.6m+): public speaking, formal ceremonies

Violations of expected personal space cause discomfort; preferences vary by:

• Culture: Mediterranean and Latin American cultures prefer closer proximity than Northern European
• Relationship: closer distance for friends than strangers
• Context: crowded trains require acceptance of reduced personal space
• Status: higher-status individuals often claim more space

Paralanguage

Vocal elements beyond words themselves:

• Tone of voice: conveys emotion and attitude (sarcasm uses contradictory tone)
• Pitch: higher when excited or nervous; lower when calm or authoritative
• Volume: loudness signals confidence or aggression; quietness suggests shyness or intimacy
• Pace: rapid speech may indicate nervousness; slow speech suggests thoughtfulness or condescension

Verbal communication

Functions of verbal communication

• Transmitting factual information clearly and efficiently
• Abstract thinking: discussing theoretical concepts, hypotheticals
• Building and maintaining social relationships through conversation
• Persuasion and influence through reasoned argument

Social class and language

Bernstein's (1971) research identified two speech codes:

Elaborated code:

• Complex grammatical structures, varied vocabulary
• Context-independent: explicit and detailed
• Used by middle class in formal settings
• Example: "I would appreciate it if you could refrain from making noise"

Restricted code:

• Simpler grammar, limited vocabulary
• Context-dependent: assumes shared understanding
• Used by working class and in informal settings across all classes
• Example: "Be quiet, will you?"

Evaluation of Bernstein's theory

Strengths:

• Highlights how language varies by social context
• Draws attention to potential educational disadvantages

Weaknesses:

• Criticised for deficit model (suggesting working-class speech is inferior rather than different)
• Oversimplifies class differences; both codes have value in appropriate contexts
• Many people switch between codes depending on situation (code-switching)

Worked examples

Example 1: 3-mark question

Question: Outline one difference between human language and animal communication. [3 marks]

Model answer: One key difference is displacement [1 mark]. Human language allows us to communicate about things not present in time or space, such as discussing events from last year or making plans for next month [1 mark]. In contrast, animal communication is typically limited to the immediate situation, such as warning calls about current dangers or signals about food that is present now [1 mark].

Examiner guidance: This answer identifies the feature (1 mark), explains it with human example (1 mark), and contrasts with animal communication (1 mark). Alternative differences include productivity/creativity or grammatical structure.

Example 2: 4-mark question

Question: Describe what psychologists have discovered about personal space. [4 marks]

Model answer: Personal space refers to the physical distance people maintain between themselves and others [1 mark]. Edward Hall identified four zones: intimate distance (0-45cm) for close relationships, personal distance (45cm-1.2m) for friends, social distance (1.2-3.6m) for formal interactions, and public distance (3.6m+) for public speaking [1 mark]. Research shows personal space preferences vary by culture, with Mediterranean cultures preferring closer proximity than Northern European cultures [1 mark]. When personal space is invaded, people experience discomfort and may step back or use other non-verbal signals like reduced eye contact to restore comfortable distance [1 mark].

Example 3: 6-mark extended response

Question: Evaluate the Sapir-Whorf hypothesis. [6 marks]

Model answer: The Sapir-Whorf hypothesis suggests language influences or determines thought, existing in strong and weak versions [1 mark].

One strength is supporting evidence from colour perception studies. Research shows that speakers of languages with more colour terms can distinguish similar shades more quickly, suggesting language influences perceptual categories [1 mark]. Additionally, the hypothesis explains why bilingual speakers sometimes report thinking differently in each language [1 mark].

However, a major weakness is the lack of support for the strong version (linguistic determinism). People can clearly understand and think about concepts even without specific words for them [1 mark]. For example, speakers of languages without future tense can still plan and think about future events [1 mark].

Another limitation is difficulty separating language effects from broader cultural factors. Differences attributed to language might actually result from different cultural practices and environmental experiences [1 mark].

Examiner guidance: Extended responses need balanced evaluation with evidence, clear structure separating strengths and weaknesses, and psychological terminology.

Common mistakes and how to avoid them

• Confusing Piaget and Sapir-Whorf: Remember Piaget says thought comes first (children understand before speaking), while Sapir-Whorf says language shapes thought. Use a mnemonic: "Piaget = Pre-linguistic thought"

• Describing NVC without explaining functions: Don't just list types of non-verbal communication; explain what each achieves (e.g., "eye contact regulates turn-taking" not just "people use eye contact")

• Treating all animal communication as identical: Von Frisch's bees show sophisticated communication, so avoid claiming animals cannot convey specific information; instead, note they lack displacement and creativity

• Oversimplifying Bernstein: Don't suggest restricted code is "worse"—recognise both codes serve different functions and contexts; note people code-switch

• Forgetting cultural variations: Always consider cultural differences in NVC, particularly for eye contact and personal space; what's appropriate in UK may differ elsewhere

• Weak evaluation: Avoid vague statements like "the theory is good." Instead, provide specific evidence: "Supported by Ekman's cross-cultural research showing universal facial expressions"

Exam technique for "Language, Thought and Communication"

• Command words matter: "Outline" needs brief description; "Describe" requires more detail; "Explain" needs reasoning; "Evaluate" demands strengths and weaknesses with evidence

• Mark allocation guides depth: For 2 marks, make two developed points or one detailed point; for 6 marks, aim for three evaluation points (typically two strengths and one weakness or vice versa), each elaborated with evidence or examples

• Use research evidence: Reference specific studies (Von Frisch, Ekman, Bernstein, Hall) to support descriptions and strengthen evaluations; examiners reward psychological knowledge

• Apply to real contexts: When questions ask for application, use realistic scenarios demonstrating understanding—job interviews for NVC, classroom settings for verbal communication codes

Quick revision summary

Language and thought interact in complex ways, with debate whether thought precedes language (Piaget) or language shapes thought (Sapir-Whorf). Human communication differs from animal systems through displacement, creativity and grammatical structure, though Von Frisch showed bees communicate detailed location information. Non-verbal communication—including eye contact, facial expressions, body language, personal space and paralanguage—conveys emotions and attitudes, with cultural variations in appropriateness. Verbal communication varies by social context, with Bernstein identifying elaborated and restricted codes. Understanding these concepts requires evaluating theories with research evidence and recognising cultural diversity.
