    Study Notes

    SAQs and Paper 3 Psychology Revision

    • 3 SAQs (no options) - 27 marks
    • Paper 3 - 24 marks
    • Responses must be fully focused on the question
    • Responses must meet the command term requirements
    • Knowledge and understanding must be accurate, addressing the main topics/problems in the question
    • Responses must be supported by research, explicitly linked to the question.
    • Introduction: Thesis statement
    • Key terms defined
    • Appropriate research (ASMPRCE) described
    • Conclusion explicitly links study to theory/concept

    Cognitive Approaches to Understanding Behaviour

    • The brain is a set of mental processes (memory, perception, thinking, language, attention)
    • Cognitive misers – avoid actively processing information to conserve time/effort
    • Schemas- frameworks based on past experiences, used to understand new experiences
    • Bartlett's study (War of the Ghosts) showed distortion, assimilation, levelling, omission, and sharpening of memories, reflecting cognitive schemas.

    Memory Models

    • Atkinson and Shiffrin's Multi-Store Model (MSM):

      • Sensory memory: initial stage, brief storage
      • Short-term memory (STM): limited capacity, temporary storage
      • Long-term memory (LTM): permanent storage, potentially unlimited

    • Baddeley and Hitch's Working Memory Model (WMM):

      • Central executive: controls attention and cognitive processes
      • Phonological loop: verbal and acoustic information
      • Visuospatial sketchpad: visual and spatial information
      • Episodic buffer: integrates information from other components

    • Displacement decay (STM): Information lost due to new information or fading over time without rehearsal/repetition

    • Serial Position effect (Primacy & Recency): Better recall of items at beginning (primacy) and end (recency) of a list

    Thinking and Decision Making

    • Biases (e.g., anchoring bias) affect decision-making
    • Thinking is the process of using knowledge/information for planning, problem-solving, and decision making
    • Dual processing model (System 1 and System 2 thinking) – (automatic vs. controlled/rational)

    Working Memory Model

    • Central Executive: Controls attention and cognitive processes
    • Phonological Loop: Stores verbal and auditory information.
    • Visuospatial Sketchpad: Stores visual and spatial information.
    • Episodic Buffer: Integrates information from other components

    Long-Term Storage Memory

    • Various types of biases affect decision making (emotional/contextual)
    • Decision making is identifying/choosing alternatives based on values/preferences
    • Thinking is critical to decision-making to formulate thoughts, problem solve, and evaluate scenarios

    Cognitive Processes and Studies

    • Loftus and Palmer: Study on eyewitness testimony
    • Glanzer & Cunitz: Study on serial position effect (STM)
    • Englich & Mussweiler: Study on anchoring bias
    • Brown & Kulick: Study on flashbulb memories
    • Maguire et al: Study on London taxi drivers (HM) and neuroplasticity
    • Draganski: Study on brain plasticity following new learning
    • Antonova et al: Study on the effect of scopolamine on memory
    • McGaugh and Cahill: Study on the effect of stress hormones on emotional memory
    • Wedekind et al: Study on MHC and mate selection
    • Caspi et al: Study on gene-environment interaction and depression

    Ethical Considerations in Research

    • Informed consent, anonymity/confidentiality, right to withdraw, deception, protection from harm, debriefing.

    Generalizability and Transferability

    • Generalizability: extent findings can be applied to broader populations.
    • Transferability: extent findings apply to similar contexts or situations

    Credibility in Research

    • Triangulation: combining methods to enhance credibility
    • Reflexivity: critical self-awareness to identify researcher influence
    • Accurate participant reporting (potential participant bias)
