Test your Short-Term Memory: How many letters can you memorize?

by

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?

Fol­low this link to mem­o­rize series of let­ters. The first 2 tri­als are very easy but the test gets quite chal­leng­ing after that!

Cognitive Ability: Brain Games or Drugs?

A recent sci­en­tif­ic study is being wel­comed as a land­mark that shows how flu­id intel­li­gence can be improved through train­ing. I inter­viewed one of the researchers recent­ly (Can Intel­li­gence Be Trained? Mar­tin Buschkuehl shows how), and con­trib­u­tor Dr. Pas­cale Mich­e­lon adds her own take with the great arti­cle that fol­lows. Enjoy!

What is intelligence? 

Intel­li­gence is a con­cept dif­fi­cult to define as it seems to cov­er many dif­fer­ent types of abilities.

One def­i­n­i­tion dis­so­ci­ates between crys­tal­lized intel­li­gence or abil­i­ties and flu­id intel­li­gence. Crys­tal­lized intel­li­gence refers to the knowl­edge acquired through­out life such as vocab­u­lary. Flu­id intel­li­gence is the abil­i­ty that allows us to adapt to new sit­u­a­tions or problems.
