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 long-term storage. Typing info into a computer Getting a girls name at a party

Storage The retention of encoded material over time. Trying to remember her name when you leave the party. Pressing Ctrl S and saving the info.

Retrieval The process of getting the information out of memory storage. Seeing her the next day and calling her the wrong name (retrieval failure). Finding your document and opening it up.

Now pick out the seven dwarves. Turn your paper over. Now pick out the seven dwarves.

Did you do better on the first or second dwarf memory exercise? 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?

Types of Memory Sensory Memory Short-Term Memory Long-Term Memory Encoding Retrieval Long-Term Memory

Sensory Memory The immediate, initial recording of sensory information in the memory system. Echoic – sensory memory for sound (last 1-2 s.) Iconic – sensory memory for vision (lasts a fraction of a second) Stored just for an instant, and most gets unprocessed.

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? You must repeat things over and over to put them into your long-term memory. Rehearsal

Long Term Memory Unlimited storehouse of information. Explicit (declarative) memories Implicit (non-declarative) memories

Explicit Memories (aka, declarative memories) Episodic Memories Episodic memory is the memory of autobiographical events (times, places, associated emotions, and other contextual who, what, when, where, why knowledge) that can be explicitly stated. Semantic Memories Semantic memory refers to a portion of long-term memory that processes ideas and concepts that are not drawn from personal experience. Semantic memory includes things that are common knowledge, such as the names of colors, the sounds of letters, the capitals of countries and other basic facts acquired over a lifetime. Formed by the hippocampus; stored in the cerebral cortex.

Implicit Memories Procedural Memories Procedural memory is a part of the long-term memory that is responsible for knowing how to do things, also known as motor skills. Conditioned Memories AKA Classical Conditioning and Operant Conditioning Formed by the cerebellum; stored in the cerebral cortex.

To summarize….

Getting the information in our heads!!!! 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. Examples: what table you were seated at a restaurant; what you ate for breakfast, where on the page a word was, who you saw on the way to class today. Things can become automatic with practice (when you first learn a new word, every time you hear it, you consciously and effortlessly pull up the definition from meaning; after hearing it 50 times, you can understand the word without effort – reading Shakespeare.)

Effortful Processing Encoding that requires attention and conscious effort. Examples: vocabulary for school, dates, names Rehearsal (conscious repetition) is the most common effortful processing technique. It depends on the amount of time spent processing the information. Overlearning (reviewing things you already know) enhances retention. (This is why Dr. Humble will probably never allow senior exam exemptions.)

Spacing Effect We increase long-term retention when we study or practice over time. Cramming is an inefficient means of studying (ie, cramming = less time for guitar hero)

Which type works best?

Chunking Organizing items into familiar, manageable units. Often it will occur automatically. Take 10 seconds to try to remember this number list: 1-4-9-2-1-7-7-6-1-8-1-2-1-9-4-1 Chunk- from Goonies Now, try again: 1492, 1776, 1812, 1941 What are some other examples of chunking?

Tricks to Encoding Mnemonic Devices = memory tricks Often use imagery (peg word, method of loci, “hippo on campus…”) May use chunking (King Philip Came Over for Great Spaghetti, SOHCOHTOA, My very earnest mother just served us nine [pizzas], ROY G. BIV) Give me some more examples…. Links to examples of mnemonic devices.

Self-Reference Effect The idea that we remember things when they relate to ourselves. What do we do in class to take advantage of this?

Study pitfalls Visual encoding: thinking about the appearance of the word Acoustic encoding: thinking about the sound of the word (unless it is set to music—then it is great for rote memorization) The next-in-line effect: we seldom remember what the person has just said or done if we are next. Information minutes before sleep is seldom remembered; in the hour before sleep, well remembered. Taped info played while asleep is registered by ears, but we do not remember it.

Quiz Question In order to remember to buy sugar, ham, oranges, and potatoes the next time he does to the grocery store, Nabil forms the word “SHOP” with the first letter of each item. He is using a memory aid known as Chunking The spacing effect The serial position effect The method of loci The next-in-line effect
