Topic Synopsis
The Memory topic covers the stages of information processing, types of forgetting, the biological basis of memory including the role of specific brain structures, and two key theoretical models: the Multi-store Model and the Theory of Reconstructive Memory. It also explores practical applications in advertising and neuropsychological measurement.
Key Concepts & Core Principles
- Hypotheses: A testable prediction (e.g., 'Students who revise with music will recall fewer words than those who revise in silence'). You need to know the difference between null and alternative hypotheses, and directional vs. non-directional.
- Variables: Independent variable (IV) is manipulated by the researcher; dependent variable (DV) is measured. Extraneous variables (e.g., noise, time of day) must be controlled to avoid confounding results.
- Sampling methods: Random, stratified, opportunity, and volunteer sampling. Each has pros and cons regarding bias and representativeness. For example, opportunity sampling is quick but may not represent the target population.
- Reliability and validity: Reliability means consistency (e.g., test-retest reliability). Validity means the study measures what it claims to (e.g., internal validity: did the IV cause the DV?). A study can be reliable but not valid.
- Ethical guidelines: Informed consent, deception, debriefing, right to withdraw, confidentiality, and protection from harm. The BPS (British Psychological Society) sets these rules. You must apply them to any study you design or evaluate.
Exam Tips & Revision Strategies
- 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.
Examiner Marking Points
- 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
