Copyright © Allyn & Bacon 2007 The Third Stage: Long-Term Memory Procedural Memory Division of LTM that stores memories for how things are done Example: How to tie a shoe Declarative Memory Division of LTM that stores explicit information (also known as fact memory) Requires some conscious mental effort Example: The capital of Boston Yes…this was intentional
Copyright © Allyn & Bacon 2007 Declarative Memory Subdivisions of Declarative Memory Episodic Memory Memory that stores personal events, or “episodes” Semantic Memory Memory that stores general knowledge, including meanings of words and concepts Google-able Memory
Copyright © Allyn & Bacon 2007 Please read the following story, and be prepared to have your memory tested for one of its sentences. This is an interesting story about the telescope. In Holland, a man named Lippershey was an eyeglass maker. One day his children were playing with some lenses. They discovered that things seemed very close if two lenses were held about a foot apart. Lippershey began experimenting, and his “spyglass” attracted much attention. He sent a letter about it to Galileo, the great Italian scientist. Galileo at once realized the importance of the discovery and set about to build an instrument of his own. He used an old organ pipe with one lens curved out and the other in. On the first clear night he pointed the glass toward the sky. He was amazed to find the empty dark spaces filled with brightly gleaming stars! Night after night Galileo climbed to a high tower sweeping the sky with his telescope. One night he saw Jupiter, and to his great surprise discovered near it three bright stars, two to the east and one to the west.

Copyright © Allyn & Bacon 2007 Eidetic Memory The so-called “photographic” memory An "unfounded myth?????" Evidence of it is found more often in children than adults Eidetic memory as observed in children is typified by the ability of an individual to study an image for approximately 30 seconds, and maintain a nearly perfect photographic memory of that image for a short time once it has been removed
Copyright © Allyn & Bacon 2007 The Biological Basis of Long-Term Memory Engram or Memory Trace Physical change in the brain associated with memory Where are memories held????…Probably anywhere Long-term Potentiation (po-TEN-she-a-shun) The long-lasting improvement in communication between two neurons that results from stimulating them simultaneously
Copyright © Allyn & Bacon 2007 Consolidation The process by which short-term memories are changed to long-term memories The Biological Basis of Long-Term Memory

Deep processing leads to better recall than shallow processing Percent of words recalled Type of Processing Shallow - Visual Visual (written in capitals?) Acoustic (rhymes with...) Semantic (type of…) Shallow - Acoustic Deep
