The brain's memory centers become weak and wither away as family members and close friends become strangers.
Someone with Alzheimer's may become unknowing over time.
People are robbed of a sense of joy, meaning, and camaraderie because of lost memory.
Alzheimer's disease strips away memory by damaging the brain.
People who win gold medals in a memory Olympics are at the other extreme.
Solomon Shereshevskii, a Russian journalist, had to listen while other reporters wrote notes.
A string of 7- to 9-digits could be parroted back by the average person.
If they were read about 3 seconds apart, S could repeat up to 70.
He could easily recall digits or words backwards.
Even after 15 years, his accuracy was unerring.
When we were in your apartment, you gave me this series.
I was sitting in the rocking chair while you were sitting at the table.
You wore a gray suit.
Consider your own memory.
You remember a lot of faces, places, and things.
In one study, students only listened to four-tenths of a second from popular songs.
As soon as we hear a familiar voice, we recognize songs.
Also, with faces and places.
There are 2500 slides of faces and places.
You can see 280 of these slides with others you've never seen.
90 percent of the slides the participants viewed in the first round were recognized by them.
In a follow-up experiment, people were exposed to 2800 images for 3 seconds each and were able to see the repeats.
Look for a target face in a sea of faces and you will recognize other faces from the scene as well.
Some superrecognizers can recognize faces.
After viewing a video of an armed robbery, one police officer spotted and arrested the bandit on a busy street.
Humans have shown remarkable memory for faces.
The sheep can remember faces.
At least one fish species can be seen spitting at familiar faces to get a food reward.
After food rewards are associated with some sheep faces, but not with others, sheep remember the faces for two years.
We'll look at these fascinating questions in this chapter.
If you study for a final exam or engage in a language used in early childhood, you will relearn the material more easily.
If you can remember most of the people in your high school graduating class, you may be able to spot their names in a list of names.
People who had graduated 25 years earlier were unable to remember many of their classmates.
If you are like most students, you can probably remember more names of Snow White's dwarfs than you can remember.
Our recognition memory is large and quick.
The mind knows before the mouth can give us an answer to millions of questions.
This was shown over a century ago by a memory researcher.
He practiced and tested a sample of syllables.
To get a feel for his experiments, quickly read aloud, eight times over, the following list (from Baddeley, 1982), then look away and try to recall the items.
After learning about the list, Ebbinghaus could not remember a lot of the words.
The less time he had to relearn the list on Day 2, the more frequently he repeated it.
Retention is increased when practice is distributed over time.
It helps to rehearse course material even after you know it.
When he practiced a list of nonsense on Day 1, the less time he had to relearn it on Day 2.
One measure of memory retention is the speed of relearning.
If Taylor Swift and Bruno Mars hadn't become famous, their high school classmates would most likely still recognize them in these photos.
The tests show that we remember more than we can remember.
Multiple-choice questions test our knowledge.
It's harder to remember information than it is to recognize it.
Retention of the material is better if you recall it.
The chances of test success are higher.
Virtual house models are created to help clients envision their future homes.
Even if imperfect, psychologists create memory models that are useful.
The models help us think about how our brain works.
To remember an event, we need to get information into our brain.
Computer models have limits.
Our memories are more fragile than a computer's.
While alternating between tasks, most computers process information in sequential order.
Specific memories arise from certain activation patterns.
Every time you learn something new, your brain's neural connections change, forming and strengthening pathways that allow you to interact with and learn from your constantly changing environment.
The classic three-step model helps us to think about how memories are processed, but today's researchers recognize other ways long-term memories form.
Most of the time what you are reading enters working memory through vision.
You could repeat the information using a rehearsal.
Your attention is focused as you integrate these memory inputs.
Information fades without focused attention.
If you think you can look up later, you don't attend to it as much.
They invested less energy and remembered less well if they knew the information would be online.
Working memory plays a key role in processing new information and connecting it to previously stored information, which is why the AtkinsonShiffrin model viewed short-term memory as a temporary holding space.
ANSWER: Active processing of incoming visual and auditory information.
Our mind has a second, unconscious track.
Other information skips the conscious encoding track and goes directly into storage.
Our two-track mind helps us remember information through both effortful and automatic tracks.
Automatic processing helps the formation of implicit memories.
If you are attacked by a dog as a child, you will automatically tense up as the dog approaches.
When you want to retrieve the information, you may visualize the location of the material you are studying.
You unintentionally note the sequence of events while going about your day.
You will be able to retrace your steps when you realize you've left your coat somewhere.
The two-track mind is efficient in information processing.
The other track is free to focus on conscious, effortful processing as one track automatically tucks away routine details.
Mental feats such as vision, thinking, and memory are not single abilities.
We split the information into different parts for separate and simultaneous processing.
Automatic processing is easy to do.
You can't help but register the meaning of the words you see in your native language when you see them on a delivery truck.
You may remember connecting letters to certain sounds.
With practice and experience, your reading became automatic.
After enough practice, you would be able to perform this task much more easily.
Driving, texting, and speaking a new language are some of the skills we develop in this way.
Our active working memory is fed by sensory memory, recording momentary images of scenes or echoes of sounds.
In one experiment, people only had to look at three rows of letters for a short time.
They could only recall half of the letters after they disappeared.
When George Sperling flashed a group of letters similar to this, people could only recall half of them.
They were able to recall a row immediately after the letters had vanished.
The tone told participants to only report the letters of the top, middle, and bottom row.
They were able to show that all nine letters were available for recall.
A fleeting memory of visual stimuli was demonstrated by Sperling's experiment.
For a few tenths of a second, our eyes register a photographic or picture-image memory of a scene, and we can recall any part of it in amazing detail.
Delaying the tone signal by more than half a second caused the image to fade.
There is a text message while you are in class.
Auditory echoes last for 3 or 4 seconds.
Short-term memory refers to what we can temporarily retain.
Our brain makes sense of incoming information and links it with stored memories as part of the related idea of working memory.
George Miller proposed that we can keep about seven pieces of information in short-term memory.
The seven wonders of the world, the seven seas, the seven deadly sins, the seven colors of the rainbow, the seven musical scale notes, and the seven days of the week are all part of Miller's magical number seven.
Miller made a hole-in-one at the age of 77, according to his daughter.
He loved that.
If nothing distracts us, we can recall about seven digits.
We remember about six letters and five words, but the number varies by task.
To prevent rehearsal, the researchers asked them to start at 100 and count backwards by threes.
After 3 seconds, people only remembered the letters half the time, and after 12 seconds, they never remembered them at all.
Short-term memories have a limited life because they don't have active processing.
Unless practiced, verbal information can be quickly forgotten.
Depending on age and other factors, working memory capacity can vary.
Young adults have more working memory capacity than older adults.
The ability to juggle multiple items while processing information aids information retention after sleeping and creative problem solving.
We do better and more efficient work when we are focused on one task at a time.
Working memory capacity seems to reflect intelligence level, unlike short-term memory capacity.
Imagine seeing a letter of the alphabet, then a question, then another letter, followed by another question.
Those who could juggle the most mental balls, who could remember the most letters, and who were able to maintain their focus were shown to have high intelligence.
They were less likely to report that their mind was wandering when they reported in.
Our ability to form new memories can be boosted by several processing strategies.
The difference between success and failure can be made by these strategies when trying to retrieve a memory.
You will probably remember sets 4 and 6 more easily than the same elements in sets 3 and 5.
Information-organizing items into familiar, manageable units allows us to recall it more easily.
Try to remember 43 numbers and letters.
It is possible to organize information into meaningful units, such as letters, words, and phrases.
It would make someone cringe.
We don't speak Chinese, but we are amazed by the Chinese reader's ability to look at and reproduce all the strokes.
The most committed sports fan may be amazed by a basketball player's recall of all the players' positions after a 4-second peek at a basketball play.
When we organize information into meaningful arrangements, we remember it better.
You can read Chinese if that's the case.
Ancient Greek scholars and orators developed many memory aids that use vivid imagery to help remember.
We remember concrete, visualizable words more easily than abstract words.
If you still recall the rock-throwing rioter sentence, it's probably because of its meaning and also because it painted a mental image.
The power of such systems is understood by memory whizzes.
Most star performers in the World Memory Championships don't have exceptional intelligence, but are better at using mnemonic strategies.
Joshua Foer wanted to see how much he could improve his memory.
He won the U.S. Memory Championship by remembering a pack of 52 playing cards in less than two minutes.
He made new memories of his childhood home.
The clear picture in his head made it possible for each card to match up.
As the test subject of his own wild memory experiment, he learned that "you don't have to be memorize packs of playing cards to benefit from a little bit of insight into how your mind works"
Chunking and mnemonic techniques are great memory aids.
Gordon Bower and his colleagues demonstrated in 1969 how to organize knowledge in a hierarchy by presenting words randomly or into categories.
The recall was two to three times better when the words were grouped.
The benefits of organizing what you study are shown in the results.
Taking lecture and text notes in an outline format may be helpful.
Information is retained better when it is distributed over time.
Experiments have shown the benefits of this.
Those who learn quickly forget quickly.
After you've studied long enough to master the material, further study becomes inefficient.
If you need to remember something within 10 days or 6 months, it's better to review it later.
The spacing effect is one of psychology's most reliable findings, and it extends to motor skills and online game performance.
It improves them.
Testing protects our memory from harmful effects of stress.
There are opportunities to improve learning and memory in the Retrieval Practice questions and Review sections.
Rereading material may lull you into a false sense of mastery, but it's better to practice retrieval.
Another memory expert said that what we recall becomes more recallable.
The daily quizzing improves introductory psychology students' course performance.
It is smart practice to occasionally rehearse with self-testing for lasting memories.
Researchers have found that we process verbal information at different levels, and that the depth of processing affects our long-term retention.
Shallow processing can be done on an elementary level, such as a word's letters, or a more intermediate level, such as a word's sound.
In one experiment, researchers flashed words to viewers.
They asked them questions that elicited different levels of processing.
The deeper semantic processing triggered by the third question yielded a better memory than the shallow processing elicited by the first question.
We have trouble processing new information if it isn't related to our experience.
The procedure is very easy.
Things are arranged into different groups.
Depending on how much is involved, one pile may suffice.
One arranges the materials into different groups after the procedure is over.
They can be placed in their appropriate places.
Once more they will be used and the whole cycle will have to be repeated.
That is a part of life.
When some students heard the paragraph you just read, without a meaningful context, they remembered little of it.
When others were told the paragraph described washing clothes, they remembered a lot more.
Do you recall the sentence about the angry rioter that we gave you at the beginning of the chapter?
Some researchers have compared our minds to theater directors who imagine the finished stage production when given a raw script.

We can avoid some mismatches by changing what we hear and see.
Learning meaningful material requires one-tenth of the effort as compared to learning nonsense material, according to his experiments on himself.
The actor can easily remember the lines with this sequence in mind.
Most people remember personally relevant information.
When asked how well certain words describe someone else, we often forget them.
Members of collectivist Eastern cultures tend to remember self-relevant and family-relevant information equally well.
The greatest long-term retention can be found in distributed practice and repeated selftesting.
The meaning of the words is what determines this.
Retention is increased by deep processing.
You can check your answer by clicking on the e-book and Appendix C of the printed text.
According to research, trying to answer these questions on your own will improve retention.
A psychologist who asks you to write down as many objects as you can remember is testing you.
Taking in information, retaining it, and getting it back out are psychological terms.
The idea of working memory is to focus on active processing that occurs in this stage.
Sensory memory can be visual or auditory.
We only have a short-term memory for new information.
Memory aids that use visual imagery are called ___________.
You can find answers in the e-book and at the back of the printed text.
I think that a man's brain is like an empty attic, and you have to stock it with furniture that you choose.
It's not a good idea to think that the little room has elastic walls.
There is a time when you forget something you know before.
Our capacity to store long-term memories is unlimited.
The brain's storage capacity was estimated by a research team to be in the same ballpark as the World Wide Web.
Some surgeons and memory researchers were interested in the patients' vivid memories after surgery.
The seeming flashbacks seemed to have been invented, not a vivid reliving of longforgotten experiences.
Karl Lashley trained rats to find their way out of a maze and then removed pieces of their brain's cortex to test their memory.
The rats had at least a partial memory of how to navigate the maze even after he removed the small brain section.
Some brain cells that fire when we experience something fire again are involved in the original experience.
