QCE Psychology Unit 3: Individual Behaviour — Flashcards & Quiz

Q1: Distinguish between sensation and perception.

Sensation is the process by which sensory receptors detect physical stimuli (light, sound, pressure) and convert them into neural signals (transduction). Perception is the brain’s interpretation and organisation of sensory information into meaningful experiences. Sensation is a bottom-up (data-driven) process, while perception involves top-down (knowledge-driven) processing that is influenced by expectations, context and prior experience.

Q2: Explain the Gestalt principles of perceptual organisation.

The Gestalt principles describe how the brain organises visual elements into meaningful patterns: Proximity — objects close together are perceived as a group. Similarity — similar objects are grouped together. Closure — the brain fills in gaps to perceive complete shapes. Continuity — elements arranged on a line or curve are perceived as related. Figure–ground — the brain distinguishes a main figure from its background. The overarching Gestalt principle is "the whole is greater than the sum of its parts."

Q3: Explain classical conditioning and identify its key components.

Classical conditioning (Pavlov, 1904) is a learning process where a neutral stimulus (NS) is repeatedly paired with an unconditioned stimulus (UCS) that naturally triggers an unconditioned response (UCR). After repeated pairings, the NS becomes a conditioned stimulus (CS) that elicits a conditioned response (CR) on its own. Key processes include acquisition (learning phase), extinction (CR weakens when CS is presented without UCS), spontaneous recovery (CR reappears after rest), generalisation (responding to similar stimuli) and discrimination (responding only to the specific CS).

Q4: Explain Skinner’s operant conditioning and the four types of consequences.

Operant conditioning (Skinner) is learning through consequences of voluntary behaviour. Positive reinforcement: adding a desirable stimulus increases behaviour. Negative reinforcement: removing an aversive stimulus increases behaviour. Positive punishment: adding an aversive stimulus decreases behaviour. Negative punishment: removing a desirable stimulus decreases behaviour. "Positive" = adding; "negative" = removing. "Reinforcement" = increases behaviour; "punishment" = decreases behaviour.

Q5: Describe Bandura’s social learning theory and the Bobo doll experiment.

Bandura’s social learning theory proposes that learning occurs through observation, imitation and modelling without requiring direct reinforcement. The Bobo doll experiment (1961) showed that children who watched an adult model behave aggressively toward an inflatable doll subsequently imitated the aggressive behaviour. Four mediational processes are required: attention (noticing the model’s behaviour), retention (remembering it), motor reproduction (ability to perform it) and motivation (willingness to imitate, influenced by vicarious reinforcement).

Q6: Describe Maslow’s hierarchy of needs.

Maslow’s hierarchy (1943) arranges human needs in a pyramid from basic to complex: (1) Physiological needs (food, water, sleep), (2) Safety needs (security, stability), (3) Love and belonging (relationships, community), (4) Esteem needs (achievement, recognition), (5) Self-actualisation (realising one’s full potential). Lower-level needs must be substantially satisfied before higher-level needs become motivating. Maslow later added self-transcendence (helping others achieve their potential) above self-actualisation.

Q7: Compare intrinsic and extrinsic motivation.

Intrinsic motivation: behaviour driven by internal satisfaction, interest or enjoyment (e.g. studying because the subject is fascinating). Extrinsic motivation: behaviour driven by external rewards or avoidance of punishment (e.g. studying to earn a high ATAR). Research suggests intrinsic motivation produces deeper learning and greater persistence. The overjustification effect: providing extrinsic rewards for intrinsically motivated behaviour can reduce intrinsic motivation.

Q8: Compare the James–Lange theory and the Cannon–Bard theory of emotion.

James–Lange theory: an event triggers a physiological response, and our perception of that response produces the emotional experience. Emotion follows the body’s reaction (e.g. "I am afraid because my heart is racing"). Cannon–Bard theory: an event simultaneously triggers both the physiological response and the emotional experience independently via the thalamus. The body’s reaction and the emotion occur at the same time, not sequentially.

Q1: Sensation involves the brain’s interpretation of sensory information into meaningful experiences.

Answer: FALSE

Sensation is the detection of physical stimuli by sensory receptors and their conversion into neural signals (transduction). Perception is the brain’s interpretation and organisation of sensory information into meaningful experiences.

Q2: The Gestalt principle of closure describes how the brain fills in gaps to perceive complete shapes.

Answer: TRUE

The Gestalt principle of closure states that the brain tends to fill in missing information to perceive incomplete figures as complete, whole shapes. This demonstrates the brain’s tendency to organise visual information into meaningful patterns.

Q3: In classical conditioning, the unconditioned stimulus (UCS) is learned through repeated pairing.

Answer: FALSE

The unconditioned stimulus (UCS) naturally and automatically triggers a response without any learning. It is the neutral stimulus (NS) that becomes a conditioned stimulus (CS) through repeated pairing with the UCS.

Q4: Negative reinforcement involves removing an aversive stimulus to increase the likelihood of a behaviour.

Answer: TRUE

Negative reinforcement increases behaviour by removing an unpleasant or aversive stimulus. For example, taking paracetamol (behaviour) removes a headache (aversive stimulus), making you more likely to take paracetamol for future headaches.

Q5: Bandura’s social learning theory requires direct reinforcement for all learning to occur.

Answer: FALSE

Bandura’s social learning theory proposes that learning can occur through observation alone, without direct reinforcement. Vicarious reinforcement (observing others being rewarded or punished) influences motivation to imitate, but the learning itself occurs through observation.

Sensation and Perception

Understanding the difference between bottom-up (sensation) and top-down (perception) processing, Gestalt principles of organisation, and factors influencing perceptual set is essential. QCAA exams frequently present visual stimuli and require you to apply perceptual theories to explain what people see and why.

Learning Theories

Classical conditioning, operant conditioning and observational learning are core theories that QCAA tests through scenario-based questions. Being able to identify conditioning components (UCS, UCR, CS, CR), types of reinforcement and punishment, and Bandura’s mediational processes in novel examples is critical for exam success.

Motivation

Maslow’s hierarchy of needs, intrinsic vs extrinsic motivation and the overjustification effect are key concepts. QCAA expects you to evaluate these theories — understanding their strengths and limitations demonstrates the critical thinking that earns top marks.

Emotion and the Biological Bases of Behaviour

Comparing theories of emotion (James–Lange vs Cannon–Bard), understanding the fight-or-flight response and the role of the autonomic nervous system provides the biological context for individual behaviour. QCAA assesses your ability to explain the physiological mechanisms underlying emotional experiences.

What does QCE Psychology Unit 3 cover about individual behaviour?

Unit 3 covers sensation and perception (including perceptual principles and illusions), learning theories (classical conditioning, operant conditioning, observational learning), motivation (Maslow’s hierarchy, drive theory) and the biology of emotion, all aligned to the QCAA syllabus.

Are these flashcards aligned to the QCAA syllabus?

Yes — every flashcard and quiz question is mapped to the QCAA senior Psychology syllabus for Unit 3: Individual Behaviour.

What study techniques work best for QCE Psychology?

Use spaced repetition for key terms and theories, practise applying concepts to real-world scenarios, and create comparison tables for learning theories. QCAA exams reward application and critical thinking over rote recall.
