Squeeze Left - Think Better (aka: Weird Science)

In today's Wall Street Journal's Ideas Market under the sub-heading "Intelligence":

An Israeli research team at the Brain Research Center of Bar-Ilan University in Ramat Gan, Israel including Dr. Abraham Goldstein and three others have discovered through controlled testing that squeezing a ball with your left hand can increase creative thinking.

In a study entitled  Unilateral Muscle Contractions Enhance Creative Thinking, the researchers have concluded, after asking the 40 subjects to squeeze a ball with their left hand--which controls the brain's right hemisphere--in advance of their taking a complicated cognitive test, that the advance activation of the right hemisphere increased their creative thinking and their correct answers on the test. 

Participants attempted to complete the Remote Associates Test after squeezing a ball with either their left or right hand. As predicted, participants who contracted their left hand (thus activating the RH) achieved higher scores than those who used their right hand and those who did not contract either hand. Our findings indicate that tilting the hemispheric balance toward the processing mode of one hemisphere by motor activation can greatly influence the outcome of thought processes.
So, my friends, in advance of your next big exam or nerve-wracking job interview, practice squeezing a ball with your left hand.  You might just be surprised at the positive results!  Leave it to Israel (it's that improbable "Yiddishe Kopf" in action again).

The Great Debate: Is it Itsy Bitsy, or Inky Dinky, of Spider Fame?

Image
For the better part of a year, I've had an on-again, off-again debate with my D.H. as to the "correct" adjective in the children's finger-play nursery rhyme, "The Itsy-Bitsy Spider" (now you know which one I favor). My D. H. insists that the correct descriptive is "inky dinky," whereas I demur.  I vaguely recollect from my own childhood, either hearing " itsy-bitsy spider ," or even more familiar to me, the description "eency-weency," referring to said spider's miniscule size, yet plucky persistance, and how he (she?) braved the violent rainstorm which "washed it out" after the arduous climb up the water spout, yet doggedly climbed the spout again, after the sun came out and 'dried up all the rain.' Many, if not most of our American nursery rhymes originated on the other side of the pond, in England, for obvious reasons: the American colonists were British in origin, and brought with them the culture an...

The End. Is there a Beginning...?

This is my first post back on Tikkun Olam since April 23rd, 2015. It does not feel real. Why is it that we never think we will ever have a JOLT in our lives that will change the entire life course we have been traveling? We continue on, day by day, complacent, even in the face of serious illness--believing that what we are living is the only reality; that it is immutable, that it is PHYSICAL: you can touch it, feel it, and it will continue to be there for you tomorrow, and tomorrow, and tomorrow... But it isn't. And it won't.  Because the unthinkable can, and does, happen, in time. To everybody. As it happened to me, almost a year ago, on August 10, 2015, when my DH - Dear Husband, of 46 years, died. I am living in an Alternate Universe. Because the universe in which I was living all my life until now, is gone. I still want to slap myself in the face and wake myself up. It's a dream. A terrible nightmare.  It's a horror movie with a frightening ending, but I will...

Hijab for Jewish Women?

Image
Someone used this phrase in a comment on a post about the hijab wearing Jewish women in Ramat Bet Shemesh Alef: "modern Hareidi community;" this is an oxymoron. Just for the record, I rarely agree with a Hareidi interpretation of anything. This mode of dress is just a bad interpretation of a good concept ( tzniyut ) taken to extremes. Personally, I cover my hair because I feel it increases my humility by remembering that there is a G-d above me ( not because of the reason of less attraction to men). I chose many years ago to do so; but I have come to believe a woman can be Orthodox without covering her hair all the time; just while in shul, and where it shows respect for the Torah, such as at shiurim, or where it is the preferred mode of dress, such as at yeshiva dinners and the like. But to go to the grocery? Not necessarily . I think the whole message of tzniyut is lost in those hijab cases: where will they go next? Hiding in the home and not going out? Sitting behind a cur...
