Mem­ory is more com­plex that we usu­ally think. Cog­ni­tive sci­ences have iden­ti­fied dif­fer­ent mem­ory sys­tems, each sup­ported by dif­fer­ent brain regions. One major dif­fer­ence is between long-term and short-term mem­ory (also called work­ing memory).

Long-term mem­ory is an unlim­ited stor­age of mem­o­ries dat­ing as far back as you can remem­ber to a few min­utes ago. For instance, when you remem­ber your first day in high-school or what you said to your col­league two min­utes ago, you are using your long-term mem­ory sys­tem. This sys­tem depends mostly on parts of the tem­po­ral (in blue here) and frontal (in green) regions of the brain.

Short-term or work­ing mem­ory is a lim­ited stor­age used to briefly keep the infor­ma­tion needed for the task at hand. For instance, when you keep in mind a phone num­ber while you are dial­ing it or when you do some men­tal cal­cu­la­tion you are using your work­ing mem­ory sys­tem. This sys­tem depends mostly on parts of the frontal (in green) and pari­etal (in yel­low) regions of the brain.

Work­ing mem­ory is cru­cial for most of the tasks we per­form daily. It is also quite vul­ner­a­ble to the aging process. Two good rea­sons to try to main­tain this func­tion! Ready to test and sharpen your short-term memory?

Despite tele­vi­sion, cell phones, and Web “twit­ter,” tra­di­tional read­ing is still an impor­tant skill. Whether it is school text­books, tech man­u­als at work, or reg­u­lar books, peo­ple still read, though not as much as they used to. One rea­son that many peo­ple don’t read much is that they don’t read well. For them, it is slow, hard work and they don’t remem­ber as much as they should. Stu­dents, for example,may have to read some­thing sev­eral times before they under­stand and remem­ber what they read.

Why? You would think that schools teach kids how to read well. Schools do try. I work with middle-school teach­ers (see http://peer.tamu.edu) and they tell me that many stu­dents are 2–3 years behind grade level in read­ing pro­fi­ciency. No doubt, tele­vi­sion, cell phones, and the Web are major con­trib­u­tors to this prob­lem, which will appar­ently get worse if we don’t empha­size and improve read­ing instruction.

Some of the blame can be placed on the fads in read­ing teach­ing, such as phon­ics and “whole lan­guage,” which some­times are pro­moted by zealots who don’t respect the need for both approaches. Much of the blame for poor read­ing skills can be laid at the feet of par­ents who set poor exam­ples and, of course, on the young­sters who are too lazy to learn how to read well.

For all those who missed out on good read­ing skills, it is not too late. I sum­ma­rize below what I think it takes to read with good speed and comprehension.

1. Read with a pur­pose.
2. Skim first.
3. Get the read­ing mechan­ics right.
4. Be judi­cious in high­light­ing and note tak­ing.
5. Think in pic­tures.
6. Rehearse as you go along.
7. Stay within your atten­tion span and work to increase that span.
8. Rehearse again soon.

1) Know Your Purpose

Every­one should have a pur­pose for their read­ing and think about how that pur­pose is being ful­filled dur­ing the actual read­ing. The advan­tage for remem­ber­ing is that check­ing con­tin­u­ously for how the pur­pose is being ful­filled helps the reader to stay on task, to focus on the more rel­e­vant parts of the text, and to rehearse con­tin­u­ously as one reads. This also saves time and effort because rel­e­vant items are most attended.

Iden­ti­fy­ing the pur­pose should be easy if you freely choose what to read. Just ask your­self, “Why am I read­ing this?” If it is to be enter­tained or pass the time, then there is not much prob­lem. But myr­iad other rea­sons could apply, such as:

o to under­stand a cer­tain group of peo­ple, such as Mus­lims, Jews, Hin­dus, etc.
o to crys­tal­lize your polit­i­cal posi­tion, such as why a given gov­ern­ment pol­icy should be opposed.
o to develop an informed plan or pro­posal.
o to sat­isfy a require­ment of an aca­d­e­mic course or other assigned reading.

Many of us have read­ings assigned to us, as in a school envi­ron­ment. Or the boss may hand us a man­ual and say Read the rest of this entry »

There are whole mar­kets (think cross­words, herbal sup­ple­ments, drugs, brain fit­ness soft­ware) aimed at help­ing us improve our memory.

Now, what is “mem­ory”? how does the process of mem­ory work?

Dr. Bill Klemm, Pro­fes­sor of Neu­ro­science at Texas A&M Uni­ver­sity, explains a very impor­tant con­cept below.

Mak­ing Mem­ory Con­sol­i­da­tion Work

By Bill Klemm,  Ph. D.

Until con­sol­i­da­tion has occurred, a short-term mem­ory is very vul­ner­a­ble, as all of us have expe­ri­enced from look­ing up a phone num­ber only to have some dis­trac­tion cause us to lose the num­ber before we can get it dialed.

What is “consolidation”?

Brain researchers use the term “con­sol­i­da­tion” for the process whereby short-term mem­ory gets made more permanent.

Here, I would like to dis­cuss some aspects of con­sol­i­da­tion that many peo­ple may not know about: why sleep is so impor­tant, why mem­ory must be prac­ticed, and how test­ing pro­motes con­sol­i­da­tion. Read the rest of this entry »
