Presentation Transcript

  1. Long-Term Memory • Information not lost from STM is then passed to LTM

  2. LTM can be divided into Sub-sections

  3. Procedural Memory (actions) • Stores knowledge of how to do things • Starts slowly, over time -> faster (automatic) • Resistant to forgetting • What examples can you think of????

  4. Declarative Memory (information) • Contains information about the world • Episodic Memory (events) • Information about yourself, things that have happened involving you • Personalised knowledge • Autobiographical • Subject to forgetting – less useful • Semantic Memory (facts) • General information about the world • Includes facts, figures and other information • Encyclopaedic • Less subject to forgetting – more useful

  5. Organisation of information in LTM – Semantic Network Theory

  6. SEMANTIC NETWORK THEORY • LTM is organised systematically into hierarchical networks arranged as interrelated categories and sub-categories • Short link between 2 concepts indicates strong association • Information is organised in terms of meaning • Information is organised as concepts • A concept is a piece of information together with the characteristics (properties) of that information • The concepts are organised hierarchically • Broadest at the top

  7. SEMANTIC NETWORK THEORY continued • Based on studies that required p’s to memorise lists of words which could be placed into any of 4 categories (not disclosed to p’s) • 60 words – presented in random order • p’s tended to recall the words in their categories (animals, vegetables, names and occupations) despite the originally random presentation

  8. Have a go at creating your own example of Semantic Network Eg. Food
