Chapter 7:Human Memory

1. Sensory Memory

   • Preserves information in its original form of a very brief time. Appears to decay in about one quarter of a second.

2. Short Term Memory

   • Is a working memory. It can maintain about 7 chuncks of unrehearsed info for up to 20 seconds.

3. Long Term Memory

   • Is an unlimited capacity store that can hold information indefinitely.

4. Schema

   • Is an organized cluster of info about an object or event.

5. Conceptual Hierarchies

   • Is a multi level classification system based on common properties among items.

6. Reality Monitoring

   • Involves deciding whether memories are based on ones perceptions of actual events or ones thoughts & imaginations.

7. Explicit Memory

   • Involves intentional recollection of previous experiences. It is conscious, accessed directly & best assessed with recall or recognition measures of retention.

8. Implicit Memory

   • Is apparent when retention is exhibited on a task that does not require intentional remembering. It is unconscious accessed indirectly & best assessed with relearning measures of retention.

9. Attention

   • Involves focusing awareness on a narrowed range of stimuli or events.

10. Encoding

    • Involves forming a memoryc ode.

11. Storage

    • Involves maintaining encoded info in memory over time.

12. Retrieval

    • Involves recovering info from memory stores.

13. Decay

    • Proposes that forgetting occurs because memory traces fade with time.

14. Long Term Potentiation (LTP)

    • is a long lasting increase in neural excitability at synapses along a specific neural pathway.

15. Retention

    • Refers to the proportion of material retained (remembered).
