  • Memory
    • Types of retrieval
      • Recognition
        • Retrieving information whilst being given options to choose from, for example multiple choice questions
      • Cued recall
        • Retrieving information whilst being given a cue to recall the information such as ‘it begins with…’
      • Free recall
        • Retrieving information without any cues or options
      • Primary effect
        • Words that appear first on the list are more likely to be recalled than the middle ones
    • Types of encoding
      • Visual encoding
        • Some memories are stored visually (what it looks like).
          • Example: If I ask you to count the windows on your house you will probably 'see' your house in your mind to count the windows.
      • Acoustic encoding
        • Some memories are stored in terms of what they sound like
          • Example: your alarm clock, if you think about you can hear the tune
      • Semantic encoding
        • Our semantic memory is the meaning of words. It is the ability to understand and use words and concepts
          • Example: you know and understand the word elephant, and can use it in a sentence
      • Tactile encoding
        • Memory of what things feel like
          • Example: apples, you can understand because you eat them alot
      • Olfactory encoding
        • Memory for smells
          • Example: Playdough because of childhood
    • Types of long-term memory
      • Episodic
        • Unique memories which are concerned with personal experiences or events e.g. a holiday
          • Declarative: Knowing that
            • Memories for facts and general knowledge. Knowing the capital city of a country
      • Semantic
        • Memories for facts and general knowledge. Knowing the capital city of a country
      • Procedural
        • Our memory for carrying out complex skills/ muscle memory e.g. bike riding. They are stored using motor code rather than verbal
          • Non-declaritive: Knowing how
    • False memory: Remembering something that never happened
    • Types of processes
      • 1. Encoding
        • The information must be translated into a form so it can be held in your brain
      • 2. Storage
        • The information is then kept in your brain for a period of time- even a lifetime
      • 3. Retrieval
        • The information has to be located and brought back out of your brain
    • Multi-store model of memory
      • Says that there is more than one memory store
      • Info arrives in our senses
        • Stays in our memory store but only for a short period of time
      • Short term store has a small capcity: it can hold approx. 7 chunks of information
        • New info pushes the old info out
        • If you rehearse this information it will move into your LTM
          • The LTM has a large capacity and can stay there indefinitely
  • Episodic: Right prefrontal area
    • If the three different types of memory are different then they should have locations
