Take out a piece of paper Name the Seven Dwarves Difficulty of Task • Was the exercise easy or difficult. It depends on what factors? •Whether you like Disney movies •how long ago you watched the movie •how loud the people are around you when you are trying to remember As you might have guessed, the next topic we are going to examine is……. Memory The persistence of learning over time through the storage and retrieval of information. So what was the point of the seven dwarves exercise? The Memory process • Encoding • Storage • Retrieval Encoding • The processing of information into the memory system. Typing info into a computer Getting a girls name at a party Storage • The retention of encoded material over time. Pressing Ctrl S and saving the info. Trying to remember her name when you leave the party. Retrieval • The process of getting the information out of memory storage. Finding your document and opening it up. Seeing her the next day and calling her the wrong name (retrieval failure). Turn your paper over. Now pick pick out the seven dwarves.

Recall v. Recognition • With recall- you must retrieve the information from your memory (fill-in-the blank tests). • With recognition- you must identify the target from possible targets (multiple-choice tests). • Which is easier? Flashbulb Memory • A clear moment of an emotionally significant moment or event. Where were you when? 1. You heard about 9/11 2. You heard about the death of a family member 3. During the OJ chase Types of Memory • Sensory Memory: • Short-Term Memory • Long-Term Memory Sensory Memory • The immediate, initial recording of sensory information in the memory system. • Stored just for an instant, and most gets unprocessed. Examples: •You lose concentration in class during a lecture. Suddenly you hear a significant word and return your focus to the lecture. You should be able to remember what was said just before the key word since it is in your sensory register. •Your ability to see motion can be attributed to sensory memory. An image previously seen must be stored long enough to compare to the new image. Visual processing in the brain works like watching a cartoon -- you see one frame at a time. •If someone is reading to you, you must be able to remember the words at the beginning of a sentence in order to understand the sentence as a whole. These words are held in a relatively unprocessed sensory memory. Short-Term Memory • Memory that holds a few items briefly. • Seven digits (plus of minus two). • The info will be stored into long-term or forgotten. How do you store things from short-term to long-term? Rehearsal You must repeat things over and over to put them into your long-term memory. Working Memory (Modern day STM) • • Another way of describing the use of short-term memory is called working memory. Working-Memory has three parts: 1. Audio 2. Visual 3. Integration of audio and visual (controls where you attention lies) Long-Term Memory • The relatively permanent and limitless storehouse of the memory system. Encoding How do you encode the info you read in our text? Getting the information in our heads!!!! Two ways to encode information • Automatic Processing • Effortful Processing Automatic Processing • Unconscious encoding of incidental information. • You encode space, time and word meaning without effort. • Things can become automatic with practice. For example, if I tell you that you are a jerk, you will encode the meaning of what I am saying to you without any effort. Effortful Processing • Encoding that requires attention and conscious effort. • Rehearsal is the most common effortful processing technique. • Through enough rehearsal, what was effortful becomes automatic. Things to remember about Encoding 1. The next-In-Line effect: we seldom remember what the person has just said or done if we are next. 2. Information minutes before sleep is seldom remembered; in the hour before sleep, well remembered. 3. Taped info played while asleep is registered by ears, but we do not remember it. Spacing Effect • We encode better when we study or practice over time. • DO NOT CRAM!!!!! Take out a piece of paper and…. List the U.S. Presidents The Presidents Washington J.Adams Jefferson Madison Monroe JQ Adams Jackson Van Buren Harrison Tyler Polk Taylor Fillmore Pierce Buchanan Lincoln A.Johnson Grant Hayes Garfield Arthur Cleveland Harrison Cleveland McKinley T.Roosevelt Taft Wilson Harding Coolidge Hoover FD.Roosevelt Truman Eisenhower Kennedy L.Johnson Nixon Ford Carter Reagan Bush Clinton Bush Jr. Dean Serial Positioning Effect • Our tendency to recall best the last and first items in a list. Presidents Recalled If we graph an average person remembers presidential list- it would probably look something like this. Encoding exercise Types of Encoding • Semantic Encoding: the encoding of meaning, like the meaning of words •Acoustic Encoding: the encoding of sound, especially the sounds of words. •Visual Encoding: the encoding of picture images. Which type works best? Self-Reference Effect • An example of how we encode meaning very well. • The idea that we remember things (like adjectives) when they are used to describe ourselves. Peg-word system Tricks to Encode • Use imagery: mental pictures Mnemonic Devices use imagery. Like my “peg word” system or…. "Mary Very Easily Makes Jam Saturday Unless No Plums." Mars, Venus, Earth, Mercury, Jupiter, Saturn, Uranus, Neptune, Pluto. Give me some more examples…. Chunking • Organizing items into familiar, manageable units. • Often it will occur automatically. 1-4-9-2-1-7-7-6-1-8-1-2-1-9-4-1 Do these numbers mean anything to you? Chunk- from Goonies 1492, 1776, 1812, 1941 how about now?
