Memory The persistence of learning over time through the storage and retrieval of information. http://www.positscience.com/test-your-brain/memory/working-memory-word-list-recall
Take out a piece of paper….. • Name the seven dwarves….. Now name them…..
Was it easy or hard? • It depends on several things…. • If you like Disney movies? • When was the last time you have seen the movie? • Are people around you being loud pain in the butts so you cannot concentrate?
Recall Versus Recognition Recall Recognition you must identify the target from possible targets multiple-choice tests • you must retrieve the information from your memory • fill-in-the blank or essay tests
Recall vs. Recognition With celebrity yearbook photos!
Instructions • I will show you an old school photo of a celebrity and ask you to identify who it is with no hints. • This is testing your recall – I am asking you to recall all of the celebrities you’ve ever seen that could possibly fit your impression of the picture. You’ll find that this is probably pretty tough. • Next, I will offer you a list of possible celebrities to choose from that might belong to that photo (like a multiple choice test). • This is testing your recognition – by asking you to choose the answer from a list of possibilities, you will probably find that when you have the opportunity to recognize the individual in question, it is easier to come up with a match. • Ready?
Recall • Who is this handsome fellow?
Recognition • A. Brad Pitt • B. Gordon Ramsay • C. Ryan Seacrest • D. Mike “The Situation” Sorentino
Recall • Who is this fine young man?
Recognition • A. Eminem • B. David Schwimmer • C. Johnny Knoxville • D. Taylor Lautner
Recall • Who is this gorgeous gal?

So which do you think is easier? Recall or Recognition? Why? Ryan Seacrest, Eminem, Fergie, Katy Perry
The Memory Process Three step process…. • Encoding: The processing of information into the memory system. • Storage: The retention of encoded material over time. • Retrieval: The process of getting the information out of memory storage.
Automatic processing • Effortful processing +Time Spent +Spacing effect +Overlearning -Next in line -Seconds before sleep -During sleep Serial Positioning Effect
Encoding Exercise The Ways we can encode… • Visual Encoding: the encoding of picture images • Acoustic Encoding: the encoding of sound, especially the sounds of words. • Semantic Encoding: the encoding of meaning.
Encoding Meaning “Whale” Q: Did the word begin with a capital letter? Structural Encoding Shallow Q: Did the word rhyme with the word “weight”? Phonemic Encoding Intermediate Q: Would the word fit in the sentence? He met a __________ in the street. Semantic Encoding Deep Craik and Lockhart (1972)
Reproduce figures A and B (image) • Recall of the figure given a verbal label will be significantly more accurate, because it was encoded both semantically and visually.
Sensory Memory • A split second holding tank for ALL sensory information. • Sperling’s research on Iconic Memory • Echoic Memory
Short Term Memory • The stuff we encode from the sensory goes to STM. • Events are encoded visually, acoustically or semantically. • Holds about 7 (plus or minus 2) items for about 20 seconds. • We recall digits better than letters. Short Term Memory Activity
Ways to remember things in STM…so they go to LTM • Chunking: Organizing items into familiar, manageable units. • Mnemonic devices • Rehearsal • Hierarchy 1-4-9-2-1-7-7-6-1-8-1-2-1-9-4-1 "Mary Very Easily Makes Jam Saturday Unless No Plums."

A seashore is a better place than the street. At first it is better to run than to walk. You may have to try several times. It takes some skill but is easy to learn. Even young children can enjoy it. Once successful, complications are minimal. Birds seldom get too close. Rain, however, soaks in very fast. Too many people doing the same thing can also cause problems. One needs lots of room. If there are no complications, it can be very peaceful. A rock will serve as an anchor. If things break loose from it, however, you will not get a second chance. The Context: Kite Flying
