Improving Driving Skills and Brain Functioning- Interview with ACTIVE’s Jerri Edwards

February 4, 2008 by Alvaro Fernandez

Jerri Edwards- Active trialToday we are for­tu­nate to inter­view Dr. Jer­ri Edwards, an Asso­ciate Pro­fes­sor at Uni­ver­si­ty of South Flori­da’s School of Aging Stud­ies and Co-Inves­ti­ga­tor of the influ­en­cial ACTIVE study. Dr. Edwards was trained by Dr. Kar­lene K. Ball, and her research is aimed toward dis­cov­er­ing how cog­ni­tive abil­i­ties can be main­tained and even enhanced with advanc­ing age.

Main focus of research

Alvaro Fer­nan­dez: Please explain to our read­ers your main research areas 

Jer­ri Edwards: I am par­tic­u­lar­ly inter­est­ed in how cog­ni­tive inter­ven­tions may help old­er adults to avoid or at least delay func­tion­al dif­fi­cul­ties and there­by main­tain their inde­pen­dence longer. Much of my work has focused on the func­tion­al abil­i­ty of dri­ving includ­ing assess­ing dri­ving fit­ness among old­er adults and reme­di­a­tion of cog­ni­tive decline that results in dri­ving difficulties.

Some research ques­tions that inter­est me include, how can we main­tain health­i­er lives longer? How can train­ing improve cog­ni­tive abil­i­ties, both to improve those abil­i­ties and also to slow-down, or delay, cog­ni­tive decline? The spe­cif­ic cog­ni­tive abil­i­ty that I have stud­ied the most is pro­cess­ing speed, which is one of the cog­ni­tive skills that decline ear­ly on as we age.

ACTIVE results

Can you explain what cog­ni­tive pro­cess­ing speed is, and why it is rel­e­vant to our dai­ly lives? 

Pro­cess­ing speed is men­tal quick­ness. Just like a com­put­er with a 486 proces­sor can do a lot of the same things as a com­put­er with a Pen­tium 4 proces­sor, but it takes much longer, our minds tend to slow down with age as com­pared to when we were younger. We can do the same tasks, but it takes more time. Quick speed of pro­cess­ing is impor­tant for [Read more…] about Improv­ing Dri­ving Skills and Brain Func­tion­ing- Inter­view with ACTIVE’s Jer­ri Edwards

Brain Teaser for the Frontal Lobes: Tipping the Scales

June 15, 2007 by Caroline Latham

Here is a new brain teas­er from puz­zle mas­ter Wes Carroll.

Tip­ping the Scales

free brain teasers for frontal lobes

Ques­tion:
The top two scales are in per­fect bal­ance. How many dia­monds will be need­ed to bal­ance the bot­tom set?

This puz­zle works your exec­u­tive func­tions in your frontal lobes by using your pat­tern recog­ni­tion, hypoth­e­sis test­ing, and logic.
ANSWER:

Four dia­monds

SOLUTION:

First add up the num­ber of clubs in the first two scales (5). Then count how many clubs are in the bot­tom scale (5). The do the same with the spades, which gets you 5 and 5. There are 4 dia­monds in the top two bal­anced scales. There­fore, it must take 4 dia­monds to bal­ance the third scale since all the oth­er mea­sure­ments are the same.

Math Brain Teaser: Concentric Shapes or The Unkindest Cut of All, Part 2 of 2

May 8, 2007 by Caroline Latham

If you missed Part 1, also writ­ten by puz­zle mas­ter Wes Car­roll, you can start there and then come back here to Part 2.

Con­cen­tric Shapes:
The Unkind­est Cut of All, Part 2 of 2

Dif­fi­cul­ty: HARDER
Type: MATH (Spa­tial)
Vitruvian Man

Ques­tion:
Imag­ine a square with­in a cir­cle with­in a square. The cir­cle just grazes each square at exact­ly four points. Find the ratio of the area of the larg­er square to the smaller.

In this puz­zle you are work­ing out many of the same skills as in Part I: spa­tial visu­al­iza­tion (occip­i­tal lobes), mem­o­ry (tem­po­ral lobes), log­ic (frontal lobes), plan­ning (frontal lobes), and hypoth­e­sis gen­er­a­tion (frontal lobes).

Solu­tion:
Two to one.

Expla­na­tion:
Draw the small­er square’s diag­o­nal to see that the the small­er square’s diag­o­nal is the diam­e­ter of the cir­cle. Divide the larg­er square into two equal rec­tan­gu­lar halves to see that the larg­er square’s side is also the diam­e­ter of the cir­cle. This means that the small­er square’s diag­o­nal equals the larg­er square’s side. (Or, if you pre­fer, sim­ply rotate the inner square by 45 degrees.) As we’ve seen in the ear­li­er puz­zle “The Unkind­est Cut Of All,” the area of the small­er square is half that of the larg­er, mak­ing the ratio two to one.

Math Brain Teaser: The Unkindest Cut of All, Part 1 of 2

April 27, 2007 by Caroline Latham

In hon­or of Math­e­mat­ics Aware­ness Month, here is anoth­er math­e­mat­i­cal brain ben­der from puz­zle mas­ter Wes Carroll.

The Unkind­est Cut of All, Part 1 of 2

Dif­fi­cul­ty: HARD
Type: MATH (Spa­tial)
Square

Ques­tion:
The area of a square is equal to the square of the length of one side. So, for exam­ple, a square with side length 3 has area (32), or 9. What is the area of a square whose diag­o­nal is length 5?

In this puz­zle you are work­ing out your spa­tial visu­al­iza­tion (occip­i­tal lobes), mem­o­ry (tem­po­ral lobes), and hypoth­e­sis gen­er­a­tion (frontal lobes).

Solu­tion:
12.5

Expla­na­tion:
I am espe­cial­ly fond of these two ways to solve this problem:

1. Draw the right tri­an­gle whose hypotenuse is the square’s diag­o­nal, and whose two legs are two sides of the square. Then use the Pythagore­an The­o­rem (a^2 + b^2 = c^2) to solve for the length of each side. Since two sides are equal, we get (a^2 + a^2 = c^2), or (2(a^2) = c^2) ). Since c is 5, 2(a^2) = 25, mak­ing a^2 equal to 25/2, or 12.5. Since the area of the square is a^2, we’re done: it’s 12.5.

2. Tilt the square 45 degrees and draw a square around it such the the cor­ners of the orig­i­nal square just touch the mid­dles of the sides of the new, larg­er square. The new square has sides each 5 units long (the diag­o­nal of the small­er square), and it there­fore has area 25. How­ev­er, a clos­er inspec­tion reveals that the area of the larg­er square must be exact­ly twice that of the small­er. There­fore the small­er square has area 25/2, or 12.5.

You can now go on to Con­cen­tric Shapes: The Unkind­est Cut of All, Part 2 of 2
