    Topic Overview

    Memory is a core topic in OCR GCSE Psychology, exploring how we encode, store, and retrieve information. You'll study two key models: the Multi-Store Model (Atkinson & Shiffrin, 1968) and the Working Memory Model (Baddeley & Hitch, 1974). Understanding these models helps explain everyday phenomena like why you forget a phone number seconds after hearing it, or why you can remember song lyrics from years ago. This topic also covers types of long-term memory (episodic, semantic, procedural) and factors affecting memory accuracy, such as context and interference.

    Memory is crucial because it underpins all learning and personal identity. In exams, you'll need to describe and evaluate the models, using research studies like Peterson & Peterson (1959) on short-term memory duration and Bahrick et al. (1975) on very long-term memory. You'll also explore practical applications, such as improving revision techniques using the encoding specificity principle or avoiding interference by spacing out study sessions.

    This topic connects to other areas of psychology, including cognitive development and mental health. For example, understanding memory distortions can help explain eyewitness testimony errors (covered in Criminal Psychology). Mastering memory gives you a solid foundation for discussing how the mind processes information, which is a key theme across the GCSE course.

    Key Concepts

    Core ideas you must understand for this topic

    • →Multi-Store Model: Sensory register, short-term memory (STM), and long-term memory (LTM) as separate stores with different capacities and durations. Information moves through attention and rehearsal.
    • →Working Memory Model: Central executive, phonological loop, visuospatial sketchpad, and episodic buffer. Emphasises active processing rather than passive storage.
    • →Types of LTM: Episodic (personal events), semantic (facts/knowledge), and procedural (skills/habits). Each is processed in different brain regions.
    • →Encoding, Storage, and Retrieval: Encoding is how information is changed for storage (e.g., acoustic in STM, semantic in LTM). Storage is maintaining information over time. Retrieval is accessing stored information.
    • →Interference Theory: Forgetting occurs because similar memories compete (proactive: old interferes with new; retroactive: new interferes with old).

    What You Need to Demonstrate

    Key skills and knowledge for this topic

    • Stages of information processing: input, encoding, storage, retrieval, and output
    • Types of forgetting: decay, displacement, and retrieval failure (lack of cues)
    • Structure and functions of the brain in memory formation
    • Impact of neurological damage on memory (hippocampus, frontal lobe, cerebellum)
    • Multi-store Model of memory structure and process
    • Theory of Reconstructive Memory structure and process
    • Application of memory techniques in advertising (cues, repetition, avoiding overload, autobiographical advertising)
    • Use of neuropsychological tests like the Wechsler Memory Scale

    Examiner Tips

    Expert advice for maximising your marks

    • 💡Ensure you can 'tell the story' of the two core studies (Wilson et al. and Braun et al.) including background, method, design, sample, materials, procedure, results, conclusions, and criticisms.
    • 💡Be prepared to link memory theory to the brain and neuropsychology, as this is an embedded theme.
    • 💡Understand how to apply memory concepts to real-world scenarios like advertising.
    • 💡When evaluating models, always use research evidence. For example, cite the case study of HM to support the Multi-Store Model (he could learn new procedures but not new facts, showing separate LTM stores).
    • 💡For 'describe' questions, include specific details like capacity (7±2), duration (STM: 18-30 seconds without rehearsal; LTM: potentially lifetime), and encoding (STM: mainly acoustic; LTM: mainly semantic).
    • 💡In evaluation, don't just list strengths and weaknesses. Use phrases like 'However, a limitation is...' and 'This is supported by...' to show critical thinking. For the Working Memory Model, mention the dual-task technique (e.g., Baddeley & Hitch, 1976) as evidence for separate slave systems.

    Common Mistakes

    Pitfalls to avoid in your exam answers

    • Misconception: Short-term memory can hold unlimited information. Correction: STM capacity is limited to about 7±2 chunks (Miller, 1956). Chunking can help, but the basic capacity is fixed.
    • Misconception: The Multi-Store Model suggests rehearsal is the only way to transfer information to LTM. Correction: While maintenance rehearsal helps, deeper processing (elaborative rehearsal) is more effective, as shown by Craik & Lockhart's Levels of Processing framework.
    • Misconception: Amnesia means you forget everything. Correction: Most amnesiacs retain procedural memory (e.g., riding a bike) but lose episodic memory. This supports the idea of multiple LTM systems.
