We Forget so we remember – Study

imagesResearchers report new findings on how the human brain retains what is most important, and avoids being overwhelmed by trivia.
By Lee Dye

We accumulate so many memories that it’s a wonder our brains don’t clog, strangling us on the trivia of our daily lives. How do we recall the memories that are important to us without flooding our brains with the details of every insignificant event? How do we separate the memories we need from the mountains of garbage? According to ongoing research, we separate the wheat from the chaff by shutting down some memories, at least temporarily, to allow that one chosen treasure to resurface. In short, we forget, so we can remember.

New research into “retrieval-induced forgetting,” an awkward phrase that is easily forgotten, is reshaping much of what we have known about how memories are organized and retrieved. Psychologists Benjamin C. Storm of the University of California, Santa Cruz, and Robert A. Bjork of UC Berkeley, along with other cognitive scientists around the world, have produced some potentially game-changing results. Continue reading

Practiced to be a perfect lier – study

lie_ah1By Tia Ghose 

The more you practice a lie, the better you get at it, say the results of a new study.

Published Nov. 12 in the journal Frontiers in Cognitive Science, the study found that, after 20 minutes of practicing their cover story, liars could respond just as quickly and easily to lies as to the truth. Moreover, they were no more likely to slip-up on falsehoods than on the truth. “After a short time of training, people can be very efficient at lying,” said Xioaqing Hu, a study co-author and psychology doctoral candidate at Northwestern University. “The difference between lying and being honest has been eliminated after the training.” Continue reading

Aga Khan museum being built near Don Mills and Eglinton in Toronto

Ten things Toronto can look forward to in 2013

One year ends, a new one arrives, and with it hopes for something better. However irrational, that is the expectation for 2013 — that things will improve for Toronto. Let’s face it, 2012 wasn’t the city’s finest year. Which is not to say that we will get our civic act together, but here are a few of the things we’re looking forward to in the 12 months ahead, in no particular order:

  • Occupying a large suburban site at Eglinton Ave. E. and Wynford Dr., the Aga Khan Museum and Ismaili Center will transform this part of Toronto. Already the magnificent complex is turning heads — for now, mostly those watching as they drive by on the northbound DVP. When complete, its effect will be felt across the city. The architects including Fumihiko Maki and Charles Correa have created a place of surpassing beauty. As an act of faith in Toronto, a gift to the city, the center is unparalleled. |…|

On Facebook – Negative vs Positive

By Christina Valhouli

LIKE many women these days, Aran Hissam, 35, of Melbourne, Fla., posted the news that she was pregnant on Facebook. On the morning of an ultrasound last year, she debated on the site whether to learn the baby’s sex, musing “to peek or not to peek?” When she failed to post an update later that day, friends started to contact her. Ms. Hissam decided to return to Facebook to share the news that her unborn baby, a girl, had been found to have fetal hydrops and given no chance of survival. Continue reading

Alzheimer’s Disease Early Cognitive Problems Identified

imagesWritten by Joseph Nordqvist

Early indicators of Alzheimer’s disease have been discovered and published in the latest issue of American Journal of Psychiatry. The findings reveal that people who are beginning to develop the disease often show problems with processing semantic and knowledge based information before severe symptoms of the disease begin showing.

The study is the first of its kind to review mild cognitive impairment (MCI) associated with Alzheimer’s disease in a systematic way and reveal the early indicators, signs and symptoms. Terry Goldberg, PhD, director of neurocognition at the Litwin Zucker Center for Research in Alzheimer’s Disease, and his colleagues developed a test to identify any problems with a person’s ability to process semantic or knowledge based information.

Spectroscopy make Breast Cancer Diagnosis easy

BC_1Written by Catharine Paddock PhD

The analysis of small deposits of calcium in breast tissue can help differentiate cancerous and benign tumors, but it is sometimes not easy to make such a diagnosis. Now a team of researchers in the US believes a new method that uses a special type of spectroscopy to locate calcium deposits during a biopsy, could greatly improve the accuracy of diagnosis.

The team, from Massachusetts Institute of Technology (MIT) and Case Western Reserve University (CWRU), writes about the work that led them to this conclusion in a paper published online in Proceedings of the National Academy of Sciences on 24 December. Continue reading
