Add slide for episodic memory
Episodic memory is the memory of autobiographical events (times, places, associated emotions, and other contextual knowledge) that can be explicitly stated. Semantic and episodic memory together make up the category of declarative memory, which is one of the two major divisions in memory. The counterpart to declarative, or explicit memory, is procedural memory, or implicit memory.[1]

3. Memory
Memory is any indication that learning has persisted over time. It is our ability to store and retrieve information.
Memory is the basis for knowing your friends, your neighbors, the English language, the national anthem, and yourself.
An event is such a little piece of time and space, leaving only a mindglow behind like the tail of a shooting star. Far a lack of a better word, we call that scintillation memory. Diane Ackerman, An Alchemy of Mind, 2004
If memory was nonexistent, everyone would be a stranger to you; every language foreign; every task new; and even you yourself would be a stranger.

7. Information Processing Model Three Stages of Memory
The Atkinson-Schiffrin (1968) three-stage model of memory includes a) sensory memory, b) short-term memory, and c) long-term memory.
Sensory Memory
Role of sensory registers is to hold sensory info just long enough to get into STM.
Provides coherence and continuity to world.
Short-Term Memory (STM) and Working Memory
Two components:
Maintenance – Holds unrehearsed info (STM)
Manipulation – Working Memory - Consciously thinking and working on info being held in STM.
Mostly uses acoustic encoding.
Module

8. Modifications to the Three-Stage Model
Some information skips the first two stages and enters long-term memory automatically.
Since we cannot focus on all the sensory information received, we select information that is important to us and actively process it into our working memory.
Module

9. Working Memory
A newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory
Working memory fades unless we rehearse it

How We Encode
Preview Question 2: How do automatic and effortful processing help us encode sights, sounds, and other sensations and transfer them into our memory system?
Some information (route to your school) is automatically processed.
However, new or unusual information (friend’s new cell-phone number) requires attention and effort.
Module

11. Automatic Processing
We process an enormous amount of information effortlessly, such as the following:
Reading an example of automatic processing after practice
Space: While reading a textbook, you automatically encode the place of a picture on a page.
Time: We unintentionally note the events that take place in a day.
Frequency: You effortlessly keep track of how many times things happen to you.
Module

12. Such processing leads to durable and accessible memories.
Effortful Processing
Committing novel information to memory requires effort just like learning a concept from a textbook.
Such processing leads to durable and accessible memories.

Processing the meaning of verbal information by associating it with what we already know or imagine.
Encoding meaning (semantic encoding) results in better recognition later than visual or acoustic encoding.
Ebbinghaus – Learning meaningful material required 1/10th the effort of meaningless material.
“The time you spend thinking about material you are reading and relating it to previously stored materials is about the most useful thing you can do in learning any new subject matter” (Wickelgren 1977)

19. Visual Encoding
Mental pictures (imagery) are a powerful aid to effortful processing, especially when combined with semantic encoding.

37. Module 21 06 23 11 An excerpt from Chapter Eight.
Take a look at the following list of numbers: 4,8,5,3,9,7,6. Read them out loud to yourself. Now look away, and spend twenty seconds memorizing that sequence before saying them out loud again.
If you speak English, you have about a 50 percent chance of remembering that sequence perfectly If you're Chinese, though, you're almost certain to get it right every time. Why is that? Because as human beings we store digits in a memory loop that runs for about two seconds. We most easily memorize whatever we can say or read within that two second span. And Chinese speakers get that list of numbers—4,8,5,3,9,7,6—right every time because—unlike English speakers—their language allows them to fit all those seven numbers into two seconds.
That example comes from Stanislas Dehaene's book "The Number Sense," and as Dehaene explains:
Chinese number words are remarkably brief. Most of them can be uttered in less than one-quarter of a second (for instance, 4 is 'si' and 7 'qi') Their English equivalents—"four," "seven"—are longer: pronouncing them takes about one-third of a second. The memory gap between English and Chinese apparently is entirely due to this difference in length. In languages as diverse as Welsh, Arabic, Chinese, English and Hebrew, there is a reproducible correlation between the time required to pronounce numbers in a given language and the memory span of its speakers. In this domain, the prize for efficacy goes to the Cantonese dialect of Chinese, whose brevity grants residents of Hong Kong a rocketing memory span of about 10 digits.
It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one would think that we would also say one-teen, two-teen, and three-teen. But we don't. We make up a different form: eleven, twelve, thirteen, and fifteen. Similarly, we have forty, and sixty, which sound like what they are. But we also say fifty and thirty and twenty, which sort of sound what they are but not really. And, for that matter, for numbers above twenty, we put the "decade" first and the unit number second: twenty-one, twenty-two. For the teens, though, we do it the other way around. We put the decade second and the unit number first: fourteen, seventeen, eighteen. The number system in English is highly irregular. Not so in China, Japan and Korea. They have a logical counting system. Eleven is ten one. Twelve is ten two. Twenty-four is two ten four, and so on.
That difference means that Asian children learn to count much faster. Four year old Chinese children can count, on average, up to forty. American children, at that age, can only count to fifteen, and don't reach forty until they're five: by the age of five, in other words, American children are already a year behind their Asian counterparts in the most fundamental of math skills.
The regularity of their number systems also means that Asian children can perform basic functions—like addition—far more easily. Ask an English seven-year-old to add thirty-seven plus twenty two, in her head, and she has to convert the words to numbers ( ). Only then can she do the math: 2 plus 7 is nine and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two tens-two, and then the necessary equation is right there, embedded in the sentence. No number translation is necessary: It's five-tens nine.
"The Asian system is transparent," says Karen Fuson, a Northwestern University psychologist, who has done much of the research on Asian-Western differences. "I think that it makes the whole attitude toward math different. Instead of being a rote learning thing, there's a pattern I can figure out. There is an expectation that I can do this. There is an expectation that it's sensible. For fractions, we say three fifths. The Chinese is literally, 'out of five parts, take three.' That's telling you conceptually what a fraction is. It's differentiating the denominator and the numerator."
The much-storied disenchantment with mathematics among western children starts in the third and fourth grade, and Fuson argues that perhaps a part of that disenchantment is due to the fact that math doesn't seem to make sense; its linguistic structure is clumsy; its basic rules seem arbitrary and complicated.
Asian children, by contrast, don't face nearly that same sense of bafflement. They can hold more numbers in their head, and do calculations faster, and the way fractions are expressed in their language corresponds exactly to the way a fraction actually is—and maybe that makes them a little more likely to enjoy math, and maybe because they enjoy math a little more they try a little harder and take more math classes and are more willing to do their homework, and on and on, in a kind of virtuous circle.
When it comes to math, in other words, Asians have built-in advantage. . .

68. Context Effects
After learning to move a mobile by kicking, infants most strongly respond when retested in the same context rather than in a different context (Rovee-Collier, 1993).

69. Déjà Vu
Déjà Vu means “I've experienced this before.” Cues from the current situation may unconsciously trigger retrieval of an earlier similar experience.
French for already seen
Happens most to well educated, imaginative, young adults when tired or stressed (Brown 2003)
Other kinds of vu
jamais vu (from the French, meaning "never seen") is used to describe any familiar situation which is not recognized by the observer
Presque vu (from French, meaning "almost seen") is the sensation of being on the brink of an epiphany. Often very disorienting and distracting, presque vu rarely leads to an actual breakthrough. Frequently, one experiencing presque vu will say that they have something "on the tip of my tongue".
Presque vu is often cited by people who suffer from epilepsy or other seizure-related brain conditions, such as temporal lobe lability.
Differences in how fast sensory systems encode information may give us this feeling, sight might be at fault.

70. Retrieving Incomplete Knowledge
Tip-of-the-tongue Phenomenon
“The answer is on the tip-of-my-tongue… It starts with Q….”
Feeling-of-knowing Experience – If you don’t know the answer, how likely is it that you could recognize the answer? People are good at this. They “know it” but can’t retrieve it.

71. Moods and Memories
We usually recall experiences that are consistent with our current mood (state-dependent memory).
Ask about childhood while in a bad mood people report more negatives than in a good mood.

Our memories are mood-congruent.
Emotions, or moods, serve as retrieval cues.
