Brain Training Report – Marty – Stage 4, Session 5

Sunday, April 1st, 2012

Stage: 4

Session number: 5

Average n-back: 2.3

This session was relatively good. I’m getting a (little) bit better at n=3, but cannot yet maintain that level of performance.

Definitely feeling a nice level of comfort with n=2. I find that if I focus my attention on the 3×3 grid as a whole, I have more success than focusing on a particular aural/visual cue and trying to remember what I just heard/saw.

Will keep working on it!

Brain Training Report – Cristina P – Stage 3, Session 39

Sunday, April 1st, 2012

Stage: 3

Session number: 39

Average n-back: 4.75

Better then a few days ago, worse then a week ago, fluctuating a lot, lately. I lose my patience during the exercises more often

Brain Training Report – Jared – Stage 3, Session 6

Thursday, March 29th, 2012

Stage: 3

Session number: 6

Average n-back: 3.6

It’s the beginning of the second week on session number 6 and I managed to jump up to n=5, only to fall all the to n=2 somehow. I think n=5 may have been a shock to my brain causing me to stumble back a bit. n=4 has become easier and n=3 is a cake walk. Though n=4 is still a challenge, I plan on jumping to n=5 a few more times this week. I’m curious as to how it will feel to complete the second week of training since I know that’s when my intelligence should get a boost.

Stage: 1

Session number: 1

Average n-back: 5.2

It was pretty easy at first, but became really difficult as the training progressed. It didn’t help that my husband was trying to confuse me while training, calling out random letters. I’d like to know if this is a “good” score or a “bad” one.

Brain Training Report – George – Double Switchback – Session 1

Monday, March 19th, 2012

Stage: 2

Average n-back: 5.4

This was a difficult session! I am looking forward to trying the other stages. How do I compare my scores to that of the others?

Working Memory as A (Neuron) Group Activity

Virtual Maze

How many neurons does it take to remember to screw in a light bulb?  Scientists have come a step closer to answering this question with a novel and very clever experiment that monitored neural activity in mice as they used their working memory to negotiate a maze in search of treasure (read ‘water treat.’)

Performed in the laboratory of David Tank, Princeton’s Henry L. Hillman Professor in Molecular Biology and co-director of the Princeton Neuroscience Institute, and published in Nature, the study showed neurons firing sequentially during a working memory task. The sequential neuronal firing patterns surprised the researchers and spanned the roughly 10-sec period that it took for the mouse to form a memory, store it and make a decision about which way to turn.

“The data reveal quite clearly that at least some form of short-term memory is based on a sequence of neurons passing the information from one to the other, a sort of ‘neuronal bucket brigade,’” said Christof Koch, a neuroscientist not involved in the study.

The design of the study itself reads like something out of science fiction: The researchers used a virtual (as opposed to a physical) maze, thereby keeping the mouse’s head still for brain imaging while he traversed the maze on a spherical treadmill.  An infrared laser-powered optical microscope detected the firing of doped neurons by their green glow.

With this setup to detect which neurons were firing, the team gave the mice a prompt telling them whether the water treat lay to the left or right a few seconds before they approach a T-junction in the maze.  If the mice stored and remembered the prompt correctly and turned the right way at the junction they would get the treat.

The firing sequences were so clear that the researchers were able to accurately predict which way the mice would turn well before they reached the junction.

Helping Kids Learn: Stress & Working Memory

classroom stress

me king mo worry

According to a new study, telling children that learning is difficult makes them better students.  This conclusion might seem somewhat counter-intuitive until we consider the detrimental impact of stress on working memory.

Published by the American Psychological Association the study sought to investigate the effect of expectations on children’s learning ability:

“By being obsessed with success, students are afraid to fail,” said Frederique Autin, PhD, from the University of Poitiers, France. “So they are reluctant to take difficult steps to master new material.”

“People usually believe that academic achievement simply reflects students’ inherent academic ability, which can be difficult to change,” said Professor Jean-Claude Croizet, PhD. “But teachers and parents may be able to help students succeed just by changing the way in which the material is presented.”

After trying to solve a set of very difficult anagrams, one group of French sixth graders received the feedback that learning is difficult and failure is common, but practice will help. A second group were simply asked how they tried to solve the problems. For both groups this was followed by a working memory test; working memory predicts many aspects of academic achievement, including reading comprehension, problem solving and IQ. Those who had heard that learning is difficult performed significantly better on the working memory test, especially on more difficult problems, than the second group or than a third control group who had neither tackled the anagrams nor talked to the researchers.

A second, similar experiment included an additional group of students who tackled simpler anagrams that this time could be solved: this group was not told that learning is difficult. All of the students then completed a reading comprehension test. The children who were told that learning is difficult scored higher than the other groups, including the students who had solved the simpler anagrams.

A third experiment also surveyed the children’s feelings about their own academic competence. Again, the group that was told that learning is difficult performed better in reading comprehension and reported fewer feelings of incompetence.

Although the impact of such one-time positive reinforcement is probably short term, the study noted, the fact that working memory capacity can be improved simply by boosting confidence and reducing fear of failure “suggests that students will benefit from education that gives them room to struggle with difficulty,” Autin said. “Teachers and parents should emphasize children’s progress rather than focusing solely on grades and test scores. Learning takes time and each step in the process should be rewarded, especially at early stages when students most likely will experience failure.”

Brain Training Report – cristina – Stage 3, Session 18

Thursday, March 8th, 2012

Stage: 3

Session number: 18

Average n-back: 4.3

Often when I think my n-back answers were bad, it turns out that I answered very accurate and when I think I did very well it turns out to be quite bad, actually. Can someone explain why? Is it normal, did this happen to others too?

Something odd – Edward

Monday, February 27th, 2012

Stage: 3

Session number: 12

Average n-back: 3.6

Hi,

I was in the midst of a training session (N=3) and was getting almost full scores on most blocks but when I progressed to the next block, I ended up with 17 errors and only 1 correct response. Does anyone have an explanation for this?

Also, I have noticed an improvement in problem-solving abilities amongst other things (even though my training has been somewhat sparse).

Many Thanks,

Edward
