  2. Students’ presentation

  3. The Memory Process • Encoding: • Storage • Retrieval

  4. Encoding • The first stage of memory system • This stage determines how the event we witness is stored in memory, and how detailed is its representation. • Selectivity in encoding reflects the limited attentional resources of the human organism

  5. Storage • The second phase of the memory system • Shorter-term and long-term memory stores • The passage of time • The number of times • The types of intervening experiences

  6. Retrieval • The final step in remembering involves the retrieval of stored information • Seldom perfect. • A variety of cognitive as well as social factors influence the retrievability of stored information • Motivation to retrieve old memories, the willingness to cooperate with the examiner, and the comprehension of what is important to recall. • Memory retrieval is strongly influenced by context. • Need cues and contexts

  7. Semantic and Episodic Memory • Semantic memory is defined as the long-term storage of all of our world knowledge, including concepts, algorithm, definitions of words • Episodic memory is conceptualized memory of specific events, including their temporal and spatial contexts.

  8. Three factors that influence the development of Memory: knowledge, strategies, and metamemory • Existing knowledge • Awareness and application of mnemonic strategies that facilitate remembering • Metamemoryrefers to understanding the properties of memory and what strategy is needed in a given situation. E.g. knowing when we have memorized a list, and what actions we need to take to maintain that list in memory. Counting numbers buying Which knowledge

  9. Knowledge development • The ability to encode, store, and retrieve information directly depends on the knowledge that one possesses. • ELT, CLT, TBLT, PBLT, Metacognition, Assimilation Accommodation, equilibrium • Conservation. • CPBT, ELTA, PVC, TBBT, Cochlear implant: • Definition of Cochlear implant • Dementia

  10. Event representations, or scripts • Scripts are generalized event representations • They are abstracted from the occurrences of similar events and, as conceptual structures, represent with varying specificity different types of events. • Scripts specify the structure of events by having slots for the participants in the events and links between these slots. What we did last week? What we did last weekend? What do we have to do with it?

  11. Example • Germination • Pollination • Fertilization • Seed dispersor

  12. Words and scripts • The encoding, storage, and retrieval of an experience needs to be connected to the script • Script: life experience is identified as an instantiation of a script is through words • It is influenced by childhood amnesia (infantile amnesia): memories from the first 3 years of life compared to the amount of memories from other periods in life.

  13. Top-down structures • Scripts influence how we experience events and retrieve specific memories, • 1. they influence what we attend to • 2. They have an interpretative function influencing the perception of ambiguous features and adding typical information where no information is available. • Think about what had happened last weekend.

  14. Congruity and mismatch • when there is a mismatch between what is expected and what is actually experienced, it is not uncommon for this mismatch to be resolved by the expectation intruding into the experience record and preventing accurate retrieval. • Scripts can be potent reminders of features of events, but they also can lead to erroneous filling in of missing or expected features and activities.

  15. Memory is constructive • Constructive view of memory. • People construct their own memory using their already existing knowledge • Fire alarm memory of children and

  16. The relationship between age, scripted knowledge, and recall • Scripts develop with age but even very young children possess scripts for familiar events, and these scripts influence the way the children reconstruct past events. • Preschoolers ma be more vulnerable to the negative effects of script-based knowledge than elementary school-aged children. • Younger children are more likely to incorposrate one-time special events into their scripts.

  17. Strategy development • Rehearsal: pattern changes with age • Organization: classification of the items to be remembered into meaningful groups or categories. Cluster effect. • Elaboration • Other mnemonic devices • Utilization deficiency • Knowing when to use a strategy

  18. Task • Look at the activity and think about ways to help learners of different age groups • Pre-operational • Concrete operational • Former operational

  19. Homework • Read chapter 7 The literate mind in Wood. • Summarize and analyze how children in different ages learn literacy. • Evaluate one activity in ELT material.
