Write down the names of the Seven Dwarves

Memory  The persistence of learning over time through the storage and retrieval of information. As you might have guessed, the next topic we are going to examine is……. So what was the point of the seven dwarves exercise?

The Memory process Encoding— Selective Attention Storage Retrieval

Encoding The processing of information into the memory system. Typing info into a computer Getting a girls name

Spacing Effect We encode better when we study or practice over time. DO NOT CRAM!!!!!

List the U.S. Presidents In your notes….

Serial Positioning Effect Our tendency to recall best the last and first items in a list. If we graph an average person remembers presidential list- it would probably look something like this. Presidents Recalled AKA--Primacy vs. Recency Effect

Types of Encoding Semantic Encoding: the encoding of meaning, like the meaning of words--BEST Acoustic Encoding: the encoding of sound, especially the sounds of words. Echoic Memory— 2 nd best Visual Encoding: the encoding of picture images. Iconic Memory— 3 rd best

Iconic Memory a momentary sensory memory of visual stimuli, a photograph like quality lasting only about a second. We also have an echoic memory for auditory stimuli. If you are not paying attention to someone, you can still recall the last few words said in the past three or four seconds.

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…. Links to examples of mnemonic devices. “My Very Excellent Mother Just Served Us Nine Pizzas.“ Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto Give me some more examples….

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).

Recall v. Recognition With recall- you must retrieve the information from your memory (fill-in-the blank or essay tests). With recognition- you must identify the target from possible targets (multiple-choice tests). Which is easier? Did you do better on the first or second dwarf memory exercise?

Retrieval Cues Things that help us remember. We often use a process called priming (the activation of associations in our memory) to help us retrieve information.

PRIMING EFFECT Priming effect occurs when people respond faster or better to an item if a similar item preceded it. For the most part, the priming effect is considered involuntary and is most likely an unconscious phenomenon. The priming effect basically consists of repetition priming and semantic priming.

Context Effects It helps to put yourself back in the same context you experienced (encoded) something. If you study at a desk at home, you will probably score higher because you take tests at a desk here at school.

Effects on Memory Mood Congruent Memory--The tendency to recall experiences that are consistent with one's current good or bad mood. –If you are depressed, you will more likely recall sad memories from you past. State Dependent Memory—recalling events encoding during a certain state of consciousness. –If you are sleepy, and remember an appt. you need to write it down because you won’t remember it until you are sleepy again.

Types of Memory According to the Three Box/Info Processing Model Sensory Memory: Short-Term Memory Long-Term Memory  Opposing theory is the Levels of Processing Model which says we tend to remember things that we deeply or elaboratively process.

Review the three stage process of Memory

Sensory Memory The immediate, initial recording of sensory information in the memory system. Stored just for an instant, and most gets unprocessed. Example: 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.

Storage and Sensory Memory George Sperling played one of three tones (each tome corresponding with a row of letters). Then he flashed the letters for less than a second and the subjects were able to identify the letters for the corresponding row,

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.

Storage and Short-Term Memory Lasts usually between 3 to 12 seconds. Can store 7 (plus or minus two) chunks of information. We recall digits better than letters. Short-term memory exercise.

Chunking—Mnemonic Device Organizing items into familiar, manageable units. Often it will occur automatically. Chunk- from Goonies Do these numbers mean anything to you? 1492, 1776, 1812, 1941 how about now?

Working Memory (Modern day STM) Another way of describing the use of short-term memory is called working memory.

Long-Term Memory The relatively permanent and limitless storehouse of the memory system. At 5 years old, Rajan would memorize the license plates of all of his parents’ guests (about 75 cars in ten minutes). He still remembers the plate numbers to this day.

Long-Term Potentiation (LTP) The current theory of how our long-term memory works. LTP is an increase in a synapse’s firing potential after brief, rapid stimulation. Memory has a neural basis. Example--If you are trying to remember a phone number, the neurons are firing neurotransmitter through the synapse. The neuron gets used to firing in that pattern and essentially learns to fire in that distinct way. It is a form of rehearsal (but for our neurons).

Flashbulb Memory A clear moment of an emotionally significant moment or event, which is easy to recall. Stress seems to enhance LTM. Where were you when? 1. You heard about 9/11 2. You heard about the death of a family member 3. When Obama became President.

Types of LTM Episodic Memory— Episodes of your life –Explicit Memory Semantic Memory— Just the facts/info –Explicit Memory Procedural Memory— Things you know how to do—usually non- declaritive –Implicit Memory

Eidetic or Photographic Memory Alexandra Luria studied a patient who would repeat a list of 70 letters or digits. The patient could do it backwards and recall it up to 1.5 years later!!!! It is like you take a picture of information and store it in your brain.

The Hippocampus Damage to the hippocampus disrupts our memory. Left = Verbal Right = Visual and Locations The hippocampus is the like the librarian for the library which is our brain.

Forgetting

Encoding Failure We fail to encode the information. It never has a chance to enter our LTM.

Test Your Memory Which is the real penny?

Forgetting Decay--Without rehearsal, we forget things over time. Ebbinghaus’s forgetting curve. Anterograde Amnesia--? Tip of the Tongue-- temporary inability to remember Semantic Network Theory—Memories are connected

Types of Retrieval Failure Proactive Interference The disruptive effect of prior learning on the recall of new information. If you call your new girlfriend your old girlfriend’s name.

Types of Retrieval Failure Retroactive Interference The disruptive effect of new learning on the recall of old information. When you finally remember this years locker combination, you forget last years.

Motivated Forgetting One explanation is REPRESSION: in psychoanalytic theory, the basic defense mechanism that banishes anxiety-arousing thoughts, feelings and memories from consciousness. Recovered Memories Why does is exist?

What do you remember from 9/11? Write down all the things you can remember from 9/11. Write down all the things you remember about each crash site. Be specific. Pentagon

Memory Construction— Reconstructive Memory We sometimes alter our memories as we encode or retrieve them. Your expectations, schemas, environment may alter your memories. Elizabeth Loftus—Lost in a Mall???

Misinformation Effect Depiction of Accident  Incorporating misleading information into one’s memory of an event.

Misinformation Effect Leading Question: About how fats were the cars going when they smashed into each other?
